Have integration tests in jacoco-it directory

问题

I have integration tests and they are executed fine, but Jacoco considers them as unit tests. How to tell Jacoco to see them as integration tests and display their graph coverage, not in the jacoco-ut directory, but it the jacoco-it directory ?

Here in the Maven configuration:

UPDATE: I was missing this bit in the maven-failsafe-plugin plugin:

<executions>
  <execution>       
    <goals>                       
      <goal>integration-test</goal>               
    </goals>                                                  
  </execution>                                                          
</executions>

After having added it as in:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
      <argLine>${failsafeArgLine}</argLine>
      <includes>
        <include>**/it/**</include>
      </includes>
    </configuration>
    <executions>
      <execution>       
        <goals>                       
          <goal>integration-test</goal>               
        </goals>                                                  
      </execution>                                                          
    </executions>                                                                   
  </plugin>

the integration tests report shows the integration tests.

回答1:

You misunderstood the pattern for the include tag of maven-failsafe-plugin. The pattern is used for the package name of the classes within the test classpath (see also https://maven.apache.org/surefire/maven-failsafe-plugin/examples/inclusion-exclusion.html).

The build-helper-maven-plugin includes all classes in src/it/java to the test classpath. Then the pattern of include tag in both test plugins (surefire, failsafe) filters the classes within this test classpath. These filtered classes are executed by the test plugins.

So the workflow is

Build-Helper-Plugin extends the set of the test classes that have to be compiled and executed. Therefore the source directive is used. The path location defined in this source directive is related to the Maven project path.
Compiler Plugin compiles the java classes.
Jacoco-Plugin should measure the coverage in the production classes with unit tests. Therefore, the normal agent has to be prepared before the tests are executed. You can specify which production code should be included or excluded in the coverage measurment (include/exclude directive). The pattern in these directives are package-based (shlashes are used instead of dots).
Surefire-Plugin executes the tests whose full-qualified class name match the pattern of the include directive. The pattern uses slashes instead of dots.
Now the Jacoco-Plugin should measure the coverage in the production classes with integration tests. Therefore, the integration agent has to be prepared before the tests are executed. And again, you can specify which production code should be included or excluded in the coverage measurment (include/exclude directive). The pattern in these directives are package-based (shlashes are used instead of dots).
The same for the Failsafe-Plugin. It executes the tests whose full-qualified class name match the pattern of the include directive. The pattern uses slashes instead of dots.
