Getting started

Running in CLI

mvn spring-boot:run

Testing and Code coverage

Run simple tests:

mvn clean test

An updated report will be generated in the folder:

/target/site/jacoco/index.html

To check if coverage level is under minimum expected (see pom.xml for details):

mvn clean verify

Details

Different results of coverage

Pay attention to slight different value of code coverage, according the way it was invoked. For example:

• with mvn clean verify there is 98% (missed 2 of 114 instructions)
• with Intellij's Run with Coverage there is 94% (missed 6 of 118 instructions)

Covering Spring Code

To cover Spring code properly pay attention to pom.xml entry:

 <execution>
    <id>default-report</id>
    <phase>verify</phase>
    <goals>
        <goal>report</goal>
    </goals>
</execution>
