The sbom-utility was designed to be an API platform to validate, analyze and edit Bills-of-Materials (BOMs). Initially, it was created to validate either CycloneDX or SPDX-formatted BOMs against official, versioned JSON schemas as published by their respective standards communities.
- Organizations may also design and supply "custom JSON schema" variants to the validate command which are perhaps designed to enforce additional data-compliance requirements.
The utility also offers commands that support analysis and editing of BOM document data including trim, patch (IETF RFC 6902) and diff (experimental).
In addition, the utility features "report" commands that can easily extract, filter, list and summarize component, service, license, resource, vulnerability and other BOM information using the utility's powerful, SQL-like query command. The query command allows select-ion of specific data from anywhere in the BOM document where data values match specified (regex) patterns.
- Report output can be produced in several formats (e.g.,
txt,csv,md(markdown) andjson) to accommodate further processing.
Note: This utility supports all CycloneDX BOM variants, such as Software (SBOM), Hardware (HBOM), Manufacturing (MBOM), Machine Learning and AI (MLBOM), Cryptographic (CBOM), etc.
The following commands, which operate against input BOMs and their data, are offered by the utility:
Command [subcommand] |
Description |
|---|---|
| validate | Enables validation of SBOMs against their declared format (e.g., SPDX, CycloneDX) and version (e.g., "2.3", "1.6", etc.) using their JSON schemas. |
| patch | Applies a JSON patch file, as defined by IETF RFC 6902, to an input JSON BOM file. |
| trim | Removes specified JSON information from the input JSON BOM document and produce output BOMs with reduced or targeted sets of information. A "SQL-like" set of parameters allows for fine-grained specification of which fields should be trimmed from which document paths. |
| diff | Experimental1: Displays the delta between two similar BOM versions in JSON (diff) patch format as defined by IETF RFC 6902. Please read "recommendations" before running. |
| query | Retrieves JSON data from BOMs using SQL-style query statements (i.e., --select <data fields> --from <BOM object> --where <field=regex>). The JSON data can be used to create custom listings or reports. |
component list |
Produces filterable listings of hardware or software components declared in the BOM. |
license list |
Produces filterable listings of license data declared in the BOM along with the associated component or service. Includes "usage policy" determinations as declared in the license.json configuration file. |
license policy |
Produces filterable listings of software and data license information and associated license usage policies as defined a license.json configuration file. |
resource list |
Produces filterable listings of resources (i.e., components and services) declared in the BOM. |
schema list |
Produces filterable listings of schema formats, versions and variants supported by the validation command.Note: Customized JSON schemas can also be permanently configured as named schema "variants" within the utility's configuration file (see the schema command's adding schemas section). |
vulnerability list |
Produces filterable listings of vulnerabilities declared in the BOM (i.e., CycloneDX Vulnerability Exploitability eXchange (VEX)) data or independently stored CycloneDX Vulnerability Disclosure Report (VDR) data stored in the BOM format. |
Experimental commands: Testing, feedback and helpful suggestions and code commits are appreciated on experimental commands.

Download and decompress the correct archive file (i.e., .tar for Unix/Linux systems and .zip for Windows) for your target system's architecture and operating system from the releases page within this repository.
The source archive will contain the following files under the root directory:
sbom-utility- binary executable. This is all most need for non-customized configurations.LICENSE- the software license for the utility (i.e. Apache 2)sbom-utility-<version>.sbom.json- a simple Software Bill-of-Materials (SBOM) for the utility
as well as sample configuration files:
config.json(optional) - copy of the default schema configuration file for optional customization (to be passed on the command line)license.json(optional) - copy of the default license policy configuration file for optional customization (to be passed on the command line)custom.json(experimental, unused) - custom validation configuration file
For convenience, the default config.json and optional license.json configuration files have been embedded in the executable and used. You can provide your own versions of these files on the command line using the --config-schema or --config-license flags respectively.
- Note: When providing configuration files using command line flags, the executable attempts to load them from the same path where the executable is run from. If you choose to keep them in a different directory, you will have to supply their location relative to the executable along with the filename.
On MacOS, the utility is not a registered Apple application and may warn you that it cannot open it the first time. If so, you will need to explicitly permit the executable to be "opened" on your system acknowledging it trusted. This process is initiated from the Finder application by using ctrl-click on the executable file and agreeing using the "Open" button.
This section provides detailed descriptions of all commands, supported flags and output formats along with usage examples.
All commands generate consistent exit codes as well as share some persistent flags which are described here:
- Exit codes: Including:
0: no error,1: application error,2: validation error, etc. - Persistent flags Including:
--input,--output,--format,--quiet,--where, etc.
Convenient links to each command:
- validate: Validates BOM data against declared or required JSON schema.
- trim: Removes uninteresting or necessary fields and data from a BOM.
- patch: Patches BOMs using IETF RFC 6902 records.
- diff: (Experimental): Displays the differences between two similar BOMs. Please read recommendations before executing.
- query: Extracts JSON objects and fields from a BOM using SQL-like queries.
- component list: Lists all component information found in a BOM.
- license
- resource list: Lists all resource information by type (e.g., components, services).
- schema list: Lists supported JSON schemas by BOM format, version and variant.
- vulnerability list: Lists vulnerability (i.e.,
VEX) information included in a BOM or standaloneVDRBOM. - completion: Generates command-line completion scripts for the this utility.
- help: Displays help and usage information for the utility or currently specified command.
All commands return a numeric exit code (i.e., a POSIX exit code) for use in automated processing where 0 indicates success and a non-zero value indicates failure of some kind designated by the number.
The SBOM Utility always returns one of these 3 codes to accommodate logic in BASH (shell) scripting:
0= no error (valid)1= application error2= validation error
This example uses the schema list command to verify its exit code:
./sbom-utility schema listverify the exit code:
echo $?which returns 0 (zero) or "no error":
0This section describes some of the important command line flags that apply to most of the utility's commands.
- format flag: with
--format - indent flag: with
--indent - input flag: with
--inputor-i - output flag: with
--outputor-o - quiet flag: with
--quietor-q - where flag: with
--where
All list subcommands support the --format flag with the following values:
txt: text (tabbed tables)csv: Comma Separated Value (CSV), e.g., for spreadsheetsmd: Markdown (GitHub-compliant tables)
Some commands, which can output lists of JSON objects, also support JSON format using the json value.
This example uses the --format flag on the schema command to output in markdown:

}All list subcommands and the validate command support the --input-file <filename> flag (or its short-form -i <filename>) to declare file contents (i.e., BOM data) the commands will read and operate on.
All commands that support the input flag can also accept data from standard input or stdin by using the - (dash) character as the value instead of a filename.

output.csvloads within a spreadsheet app like MS Excel.
All commands support the --quiet flag. By default, the utility outputs informational (INFO), warning (WARNING) and error (ERROR) text along with the actual command results to stdout. If you wish to only see the command results (JSON) or report (tables) you can run any command in "quiet mode" by simply supplying the --quiet or its short-form -q flag.
This example shows the --quiet flag being used on the schema command to turn off or "quiet" any informational output so that only the result table is displayed.

...All list subcommands support the --where flag. It can be used to filter output results based upon matches to regular expressions (regex) by using the output list's column titles as keys.
Multiple key-value (i.e., column-title=regex) pairs can be provided on the same --where filter flag using commas.
Syntax: [--where key=regex[,...]]
See each command's section for contextual examples of the --where flag filter usage.
This command will parse standardized SBOMs and validate it against its declared format and version (e.g., SPDX 2.3, CycloneDX 1.6).
- Custom variants of standard JSON schemas can be used for validation by supplying the
--variantname as a flag. - Explicit JSON schemas can be specified using the
--forceflag.
Use the schema command to list supported schemas formats, versions and variants.
- A "supported" schema is already "built-in" to the utility resources along with any dependent schemas it imports.
- This means that BOM files can be validated when there is no network connection to load the schemas from remote locations (a.k.a., "off-line" mode).
Customized JSON schemas can also be permanently configured as named schema "variants" within the utility's configuration file. See adding schemas.
- Overriding default schema
- Using the
--forceflag and passing in a URI to an alternative JSON schema.
- Using the
- "Customized" schema variants, perhaps derived from standard BOM schemas, can be used for validation using the
--variantflag (e.g., industry or company-specific schemas).- Note: These variants need to be built into the utility binary as a resource.
The following flags can be used to improve performance when formatting error output results:
You can override the schema used for validation (which defaults to the schema that matches the declared format and version found in the input BOM file) by providing a different one using the --force flag. This may be useful to verify a BOM contents against a newer specification version or provide a customized schema.
- Note: The
--forceflag works with schema files with valid URIs which include URLs (e.g., 'https://') and files (e.g., 'file://').
Use the --error-limit x (default: 10) flag to reduce the formatted error result output to the first x errors. By default, only the first 10 errors are output with an informational messaging indicating x/y errors were shown.
Use the --error-value=true|false (default: true) flag to reduce the formatted error result output by not showing the value field which shows detailed information about the failing data in the BOM.
Use the --colorize=true|false (default: false) flag to add/remove color formatting to error result txt formatted output. By default, txt formatted error output is colorized to help with human readability; for automated use, it can be turned off.

]In many cases, BOMs may have many errors and having the value information details included can be too verbose and lead to large output files to inspect. In those cases, simply set the error-value flag to false.
Rerunning the same command with this flag set to false yields a reduced set of information.

]This command is able to "trim" one or more JSON keys (fields) from specified JSON BOM documents effectively "pruning" the JSON document. This functionality helps consumers of large-sized BOMs that need to analyze specific types of data in large BOMs in reducing the BOM data to just what is needed for their use cases or needs.
This command is used to output, using the --output-file flag, a "trimmed" BOM in JSON format.
json(default)
Trim operates on a JSON BOM input file (see --input-file flag) and produces a trimmed JSON BOM output file using the following flags:
A comma-separated list of JSON map keys. Similar to the query command's --select flag syntax.
A comma-separated list of JSON document paths using the same syntax as the query command's --from flag.
A flag that normalizes the BOM data after trimming and prior to output.
This flag invokes custom code that sorts all components, services, licenses, vulnerabilities, properties, external references, hashes and most other BOM data using custom comparators.
Each comparator uses required fields and other identifying fields to create "composite keys" for each unique data structure.
The original BOM used for these examples can be found here:

}This experimental command is able to "patch" an existing JSON BOM document using an IETF RFC6902 "JavaScript Object Notation (JSON) Patch" file.
The current implementation supports the following "patch" operations:
- "add", "update", "remove" and "test"
At this time the "move" or "copy" operations are not supported.
Patches work for both simple (i.e., integer, float, boolean and string) values as well as complex values such as JSON objects, maps and arrays.
This command is used to output, using the --output-file flag, a "patched" BOM in JSON format.
json(default)
The patch command operates on a JSON BOM input file (see --input-file flag) as well as an IETF RFC6902-formatted "patch' file and produces a "patched" version of the input JSON BOM as output using the following flags:
The --patch-file <filename> flag is used to provide the relative path to the IETF RFC6902 patch file to applied to the BOM input file.
A flag that normalizes the BOM data after patching and prior to output.
This flag invokes custom code that sorts all components, services, licenses, vulnerabilities, properties, external references, hashes and most other BOM data using custom comparators.
Each comparator uses required fields and other identifying fields to create "composite keys" for each unique data structure.
This section contains examples of all supported patch operations (i.e., add, replace, test) including values that are primitives (i.e., numbers, strings) as well as JSON objects and may be indexed JSON array elements.
- Example 1: "add" BOM
serialNumber - Example 2: "add" (update) BOM
version - Example 3: "add"
supplierobject tometadata - Example 4:"add"
propertyobjects tometadata.propertiesarray - Example 5: "replace"
versionandtimestampvalues - Example 6: "remove"
propertyfrom themetadata.propertiesarray - Example 7: "test" if a
propertyexists in themetadata.propertiesarray
This example adds a new top-level key "serialNumber" and corresponding value to a CycloneDX JSON BOM file.
The original CycloneDX JSON BOM file: test/patch/cdx-1-5-simplest-base.json has no serial number:

}This command allows you to perform SQL-like queries into JSON format SBOMs. Currently, the command recognizes the --select and --from as well as the --where filter.
The --from clause value is applied to the JSON document object model and can return either a singleton JSON object or an array of JSON objects as a result. This is determined by the last property value's type as declared in the schema.
The --select clause is then applied to the --from result set to only return the specified properties (names and their values).
If the result set is an array, the array entries can be reduced by applying the --where filter to ony return those entries whose specified field names match the supplied regular expression (regex).
Note: All query command results are returned as valid JSON documents. This includes a null value for empty result sets.
The query command only supports JSON output.
json(default)
The query command does not support formatting of output results as JSON format is always returned.
This example effectively extracts the first-order package manifest from the SBOM.
In this example, only the --from clause is needed to select an object. The --select clause is omitted which is equivalent to using the "select all" wildcard character * which returns all fields and values from the component object.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from metadata.componentis equivalent to using the wildcard character (which may need to be enclosed in single or double quotes depending on your shell):
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --select '*' --from metadata.component -q{
"name": "Example Application v10.0.4",
"bom-ref": "pkg:oci/example.com/product/application@10.0.4.0",

}
],
"licenses": [
{
"license": {
"id": "Apache-2.0"
}
}
],
...In this example, the --from clause references the top-level metadata.supplier object.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from metadata.supplier -q{
"contact": [
{
"email": "distribution@example.com"
}
],
"name": "Example Co. Distribution Dept.",
"url": [
"https://example.com/software/"
]
}In this example, the --from clause references the singleton JSON object component found under the top-level metadata object. It then reduces the resultant JSON object to only return the name and value fields and their values as requested on the --select clause.
./sbom-utility query --select name,version --from metadata.component -i examples/cyclonedx/SBOM/juice-shop-11.1.2/bom.json --indent 2 -qThe result, which also uses the --indent 2 flag:
{
"name": "juice-shop",
"version": "11.1.2"
}In this example, the --from filter will return the entire JSON components array.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from components -q[

]Note: The command for this example only used the --from flag and did not need to supply --select '*' as this is the default.
In this example, the --where filter will be applied to a set of properties results to only include entries that match the specified regex.
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --from metadata.properties --where name=urn:example.com:classification -q[
{
"name": "urn:example.com:classification",
"value": "This SBOM is Confidential Information. Do not distribute."
}
]additionally, you can apply a --select clause to simply obtain the matching entry's value:
./sbom-utility query -i test/cyclonedx/cdx-1-4-mature-example-1.json --select value --from metadata.properties --where name=urn:example.com:classification -q[
{
"value": "This SBOM is Confidential Information. Do not distribute."
}
]Primarily, this command is used to extract, filter and list CycloneDX BOM component data using component list.
This command supports the --format flag with any of the following values:
txt(default),csv,md
Use the --summary flag on the component list command to produce a summary report with reduced column information.
This example shows the component list with all column information display. Since CycloneDX component data can be very extensive, many columns simply indicate the component has more data available which can be extracted using the query command if needed.

This command is used to aggregate and summarize software, hardware and data license information included in the SBOM. It also displays license usage policies for resources based upon concluded by SPDX license identifier, license family or logical license expressions as defined in he current policy file (i.e., license.json).
The license command supports the following subcommands:
- list - list or create a summarized report of licenses found in input SBOM.
- list with --summary flag - As full license information can be very large, a summary view is often most useful.
- policy - list user configured license policies by SPDX license ID, family name and other filters.
The list subcommand produces JSON output which contains an array of CycloneDX LicenseChoice data objects found in the BOM input file without component association. LicenseChoice data, in general, may provide license information using registered SPDX IDs, license expressions (of SPDX IDs) or license names (not necessarily registered by SPDX). License data may also include base64-encoded license or legal text that was used to determine a license's SPDX ID or name.
This command supports the --format flag with any of the following values:
json(default),csv,md- using the
--summaryflag:txt(default),csv,md

The resource command is geared toward inspecting various resources types and their information from SBOMs against future maturity models being developed as part of the OWASP Software Component Verification Standard (SCVS). In the SCVS model, a "resource" is the parent classification for software (components), services, Machine Learning (ML) models, data, hardware, tools and more.
Primarily, the command is used to generate lists of resources, by type, that are included in a CycloneDX SBOM by invoking resource list.
This command supports the --format flag with any of the following values:
txt(default),csv,md
Currently, all resource list command results are sorted by resource type then by resource name (required field).

The completion command can be invoked as follows:
./sbom_utility completion [shell]where valid values for shell are:
- bash
- fish
- powershell
- zsh
The utility supports the help command for the root command as well as any supported commands

./sbom-utility help validateThis section contains experimental commands that will be promoted once vetted by the community over two or more point releases.
This experimental command will compare two similar BOMs and return the delta (or "diff") in JSON (diff-patch format) or text. This functionality is "JSON aware" and based upon code ancestral to that used to report file diffs between git commits.
- Even with BOMs that SHOULD be similar, it is recommended to use the trim command to remove data that changes within a BOM from one generation to another or is often proprietary such as: bom-ref, hashes, timestamp(s), properties, etc..
- In addition, it is recommended that you also
--normalizetrimmed output data to better guarantee ordering of fields and array data.
- This command is undergoing analysis and tests which are exposing some underlying issues around "moved" objects in dependent diff-patch packages that may not be fixable and have no alternatives.
- Specifically, the means by which "moved" objects are assigned "similarity" scores appears flawed in the case of JSON.
- Additionally, some of the underlying code relies upon Go maps which do not preserve key ordering.

The entirety of the code contains the tag "TODO" with comments of things that are features or improvements conceived while authoring the base functionality. Most of these do not have active issues opened form them.
Feel free to "grep" for the "TODO" tag, open an issue and/or submit a draft PR.
An ad-hoc list of featured "TODOs" geared at making the tool more accessible, extensible and useful especially around "core" commands such as validation.
- Merge command Support merge of two (both validated) SBOMs with de-duplication and configurable. Please note that some method of normalization prior to merge will be necessary.
- Remote Schema loading Support using SBOM schema files that are remotely hosted (network accessible) from known, trusted source locations (e.g., releases of SPDX, CycloneDX specification schemas). Note that the config file has an existing
urlfield per entry that can be used for this purpose. - --orderby Support ordering of query result sets by comparison of values from a specified field key.
- license.json Document license policy configuration JSON schema structure and how to add entries relative to a CycloneDX
LicenseChoiceobject for entries with SPDX IDs and those without. - license.json Add entries for all SPDX licenses listed in v3.21.
- See issue: #12
- Go libraries Replace
go-prettyjson,go-multimaplibraries with alternatives that produce maintained releases.
The utility itself is written in Go to advantage the language's built-in typing enforcement and memory safe features and its ability to be compiled for a wide range of target platforms and architectures.
The utility also is designed to produce output formats (e.g., JSON) and handle exit codes consistently to make it immediately useful standalone or as part of automated Continuous Integration (CI) tool chains for downstream use or inspection.
Further commands and reports are planned that prioritize use cases that enable greater insight and analysis of the legal, security and compliance data captured in the SBOM such as component provenance and signage (e.g., verifying resource identities by hashes or fingerprints).
In addition, inclusion of Continuous Integration and Delivery (CI/CD) or "build integrity" information around the BOM component is anticipated as part of the CycloneDX Formulation work which will require features for workflow insights.
The utility additionally prioritizes commands that help provide insight into contents of the BOM to search for and report on missing (i.e., completeness) or specific data requirements (e.g., organization or customer-specific requirements).
In general, the goal of these prioritized commands is to support data verification for many of the primary BOM use cases as identified by the CycloneDX community (see https://cyclonedx.org/use-cases/). Functional development has focused on those use cases that verify inventory (resource identity), legal compliance (e.g., license), and security analysis (e.g., vulnerability) which are foundational to any SBOM.
In the future, we envision support for additional kinds of BOMs (e.g., Hardware (HBOM), Machine Learning (MLBOM), etc.) with each again having different data requirements and levels of maturity which will increase the need for domain-specific validation. Specifically, this utility intends to support the work of the OWASP Software Component Verification Standard (SCVS) which is defining a BOM Maturity Model (BMM).
The following development-oriented topics are included in this section:
- Prerequisites
- Building
- Running from source
- Debugging
- Adding new SBOM formats, schema versions and variants
- Go v1.20.1 or higher: see https://go.dev/doc/install
gitclient: see https://git-scm.com/downloads
To build an executable of the utility compatible with your local computer's architecture use the build target in the project's Makefile:
cd sbom-utility/
make buildThe will produce a binary named sbom-utility with version set to latest in the project's release directory.
$ ls
-rwxr-xr-x 1 User1 staff 11501122 Jan 24 08:29 sbom-utility$ ./sbom-utility version
Welcome to the sbom-utility! Version `latest` (sbom-utility) (darwin/arm64)Note The binary created using make build will be for the local system's operating system and architecture (i.e., GOOS, GOARCH). This would effectively match what would be reported using the uname -s -m unix command when run on the same local system.
If you wish to build binaries for all supported combinations of GOOS and GOARCH values, use the release target (i.e., make release) which will produce named binaries of the form sbom-utility-${GOOS}-${GOARCH} under the release directory (e.g., sbom-utility-darwin-amd64).
Developers can run using the current source code in their local branch using go run main.go. For example:
go run main.go validate -i test/cyclonedx/cdx-1-4-mature-example-1.jsonThis project was developed using VSCode and can be seamlessly loaded as a project.
In order to see global variables while debugging a specific configuration, you can add the "showGlobalVariables": true to it within your launch.json config. file:
{
"showGlobalVariables": true,
"name": "Test name",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "main.go",
"args": ["validate", "-i", "test/cyclonedx/cdx-1-3-min-required.json","-t"]
},or add it globally to the settings.json file:
- Use
Command-Shift-Pto opensettings.json - Select "Preferences: Open Settings (JSON)"
- Add the following block at the top level:
"go.delveConfig": {
"showGlobalVariables": true
},Note: The showGlobalVariables setting was only recently disabled as the default in VSCode as a stop-gap measure due to performance (loading) problems under Windows.
The utility uses the config.json file (either the default, embedded version or the equivalent provided on the command line using --config-schema flag) to lookup supported formats and their associated versioned JSON schema files. To add another SBOM format simply add another entry to the format array in the document:
{
"canonicalName": "SPDX",
"propertyKeyFormat": "SPDXID",
"propertyKeyVersion": "spdxVersion",
"propertyValueFormat": "SPDXRef-DOCUMENT",
"schemas": [
{
...
}
]
...
}The value for propertyKeyFormat should be the exact name of key field that would appear in the JSON SBOM itself which can be used to confirm it is indeed a format match. In addition, the corresponding value to match for that key should be declared in the propertyValueFormat value.
The fields canonicalName, propertyKeyFormat, propertyKeyVersion, and propertyValueFormat are required. The format object MUST have at least one valid schema object.
An example schema object for the canonical SPDX v2.3 (default, no variant) schema appears as follows:
{
{
"version": "SPDX-2.3",
"variant": "",
"name": "SPDX v2.3",
"file": "schema/spdx/2.3/spdx-schema.json",
"development": "https://github.com/spdx/spdx-spec/blob/development/v2.3/schemas/spdx-schema.json",
"url": "https://raw.githubusercontent.com/spdx/spdx-spec/development/v2.3/schemas/spdx-schema.json",
"default": true
},
},- Add a copy of the JSON schema file locally in the project under the structure
resources/schema/<format>/<version>/<schema filename>.- Note If the schema exists under the
resourcesdirectory, it will automatically be embedded in in the executable binary when built usinggo buildwhich includes using the project'sMakefile.
- Note If the schema exists under the
- Assure only one
schemaobject entry for a given format and version has the valuelatestset totrue. This latest schema will be used when the SBOM being validated does not have a clear version declared or used with the--force latestflag. - If you have a customized or "variant" version of a schema (with the same format and version values) you wish to use for validation (e.g., a
corporateorstagingversion with added requirements or for testing an unreleased version), you can create an entry that has the sameversionas another entry, but also declare itsvariantname (non-empty value). This value can be supplied on the commend line with the--variant <variant name>flag to force the validator to use it instead of the default (empty variant value).
Testing implementation and invocation, with examples, is described in this section including:
The built-in go test command will execute all functional tests that appear in files named with the pattern: <filename>_test.go. These files are executed from within the same directory (package) where its respective <filename>.go source code file is located and sets that same as the "working directory".
For example, tests in the validate_test.go file are executed from the cmd subdirectory.
This is normally a problem as the actual test SBOM JSON test files are located relative the project root, one level higher, and would not be found by the "working directory". In order to correct for that, the test working directory is automatically changed for all tests within the TestMain routine found in root_test.go.
The Makefile includes a test target for convenience which will use go test to run all tests found in all subdirectories:
make testThe test_cmd target will use run only the test found in the cmd package:
make test_cmdThe test_schema target will use run only the test found in the schema package:
make test_schemaExample: running all tests in the cmd package:
go test github.com/CycloneDX/sbom-utility/cmd -vExample: running all tests in the schema package:
go test github.com/CycloneDX/sbom-utility/schema -vRun in "quiet" mode to not see error test output:
go test github.com/CycloneDX/sbom-utility/cmd -v --quietrun an individual test within the cmd package:
go test github.com/CycloneDX/sbom-utility/cmd -v -run TestValidateCdx14MinRequiredBasicSimply append the flags --args --trace or --args --debug to your go test command to enable trace or debug output for your designated test(s):
go test github.com/CycloneDX/sbom-utility/cmd -v --args --traceNote: You should always use the --args flag of go test as this will assure non-conflict with go test built-in flags which is the case with the --trace flag.
Several tests will still output error and warning messages as designed. If these messages are distracting, you can turn them off using the --quiet flag.
go test github.com/CycloneDX/sbom-utility/cmd -v --quietIn order to initiate the release workflow, simply go to the release page of the repository:
and click on the Draft a new release button. Follow the instructions to create a new version tag, provide an appropriate release title and description and publish the release. The GitHub release workflow will be triggered automatically.
For local development, you may choose to make a release on your machine using the Makefile directive release:
make releaseAfter all builds are done, the binaries and config. files can be verified to be in the target release directory:

to produce a release version you can set the following flags and invoke go build directly:
BINARY=sbom-utility
VERSION=latest
LDFLAGS=-ldflags "-X main.Version=${VERSION} -X main.Binary=${BINARY}"
$ go build ${LDFLAGS} -o ${BINARY}TODO: Update the Makefile's release target to conditionally pull the release version from environment variable values and only uses the hardcoded values as defaults when not found in the runtime build environment.
