Simple XCTest Log Formatter in Swift

This is the repo with the sample code for the blog post "Simple XCTest Log Formatter in Swift".

For more information visit https://vojtastavik.com/2019/04/23/xctest-log-formatter/.

Example

All tests passed

Some of the tests failed

Usage

1. Clone this repository

$ git clone https://github.com/VojtaStavik/XCTest-Log-Formatter.git

2. Make sure the formatter file is executable:

$ cd XCTest-Log-Formatter
$ chmod +x format_xctest_log.swift

3. Copy the formatter file to the repo you want to use it in or simply copy it to /usr/local/bin to make it accessible from everywhere:

cp format_xctest_log.swift /usr/local/bin

4. Because the formatter formats only the test logs, you need to separate the build and test steps.

Here are the example commands for Alamofire:

# The build step still uses xcpretty :
$ xcodebuild build-for-testing \
-workspace Alamofire.xcworkspace \
-scheme "Alamofire iOS" \
-sdk iphonesimulator \
ENABLE_TESTABILITY=YES \
| xcpretty

# The test step uses the new formatter:
$ xcodebuild test-without-building \
-workspace Alamofire.xcworkspace \
-scheme "Alamofire iOS" \
-destination "id=FE78C58A-0776-41C0-BE1C-FC7C3A07853A" \
| format_xctest_log.swift
