如何在maven-cobertura-plugin中运行cobertura测试？

Question

In order to fine-tune which tests are run at which times and in which environments, we have several executions set up for the maven-surefire-plugin. We set the default configuration to skip all tests, then enable them for the executions we want. This by itself works well for us.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
     <skip>true</skip>
  </configuration>
  <executions>
     <execution>
       <id>unit-tests</id>
       <phase>test</phase>
       <goals>
          <goal>test</goal>
       </goals>
       <configuration>
          <skip>false</skip>
          <includes>
             <include>**/*Tests.java</include>
          </includes>
          <excludes>
             <exclude>**/*IntegrationTests.java</exclude>
          </excludes>
       </configuration>
     <execution>
     <execution>
       <id>integration-tests</id>
       <phase>integration-test</phase>
       <goals>
          <goal>test</goal>
       </goals>
       <configuration>
          <skip>false</skip>
          <includes>
             <include>**/*IntegrationTests.java</include>
          </includes>
       </configuration>
     <execution>
   </executions>
</plugin>

When I add the maven-cobertura-plugin to the mix, I run into problems. The cobertura goal runs, and successfully instruments my classes. However, no tests get run. I assume this is because the test execution that cobertura is running in is one that is skipped. However, I cannot find how to specify which phase and goal to set up for this execution. When I turn on all tests, the output seems to indicate that these are still running in these unit-tests and integration-tests phases/goals.

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>cobertura-maven-plugin</artifactId>
  <version>2.4</version>
  <configuration>
     <formats>
        <format>xml</format>
        <format>html</format>
     </formats>
  </configuration>
  <executions>
     <execution>
        <phase>package</phase>
        <goals>
           <goal>cobertura</goal>
        </goals>
     </execution>
  </executions>
</plugin>

How do I need to specify a surefire execution so that the cobertura will run it against the instrumented classes?

Answer 1

You will note from the docs that cobertura:cobertura

• Must be wired as a report
• Instruments, tests and generates a report
• Runs in its own lifecycle cobertura (not the default lifecycle)
• Invokes lifecycle phase test before running itself

So, wiring it accordingly should automatically result in instrumentation and testing.
