Integration test is run on projects that contains the plugin maven-test-plugin under the POM build configuration.
Since integration test itself is for testing, the <testSourceDirectory> is no longer needed and the <sourceDirectory> is enough to be able to run the project test successfully. The following POM snippet is an example build configuration of an integration test project.
<build>
<sourceDirectory>./</sourceDirectory>
<plugins>
[...]
<plugin>
<groupId>npanday.plugin</groupId>
<artifactId>maven-test-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<integrationTest>true</integrationTest>
</configuration>
</plugin>
</plugins>
</build>
To run the test, simply import the project and execute the NPanday's test goal. You can refer to Importing Projects and Test sections for instructions on importing and executing test goal respectively.
