Inclusions and Exclusions of Tests

Inclusions

By default, the Failsafe Plugin will automatically include all test classes with the following wildcard patterns:

  • "**/IT*.java" - includes all of its subdirectories and all Java filenames that start with "IT".
  • "**/*IT.java" - includes all of its subdirectories and all Java filenames that end with "IT".
  • "**/*ITCase.java" - includes all of its subdirectories and all Java filenames that end with "ITCase".

If the test classes do not follow any of these naming conventions, then configure Failsafe Plugin and specify the tests you want to include.

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.18</version>
        <configuration>
          <includes>
            <include>Sample.java</include>
          </includes>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

Exclusions

There are certain times when some tests are causing the build to fail. Excluding them is one of the best workarounds to continue the build. Exclusions can be done by configuring the excludes property of the plugin.

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.18</version>
        <configuration>
          <excludes>
            <exclude>**/CircleIT.java</exclude>
            <exclude>**/SquareIT.java</exclude>
          </excludes>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

Regular Expression Support

An include/exclude pattern can be an ant-style path expression, but regular expressions are also supported through this syntax:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>2.18</version>
        <configuration>
          <includes>
            <include>%regex[.*[Cat|Dog].*Test.*]</include>
          </includes>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

Note the syntax %regex[expr], where expr is the actual expression and the rest is just wrapping. Also note that regex matches are done over *.class files and not *.java files.
