Maven 'test' command that only runs the tests that failed

Question

Is there a way to call the maven 'test' command that only runs the tests that failed the last time it was called?

Answer 1

Try using the surefire plugin's runOrder parameter. It doesn't look like it has an ${expression} allowing you to change the property from the command line, so I would roll my own:

... POM stuff here....
<properties>
    <!-- plugin's default value for this param -->  
    <surefire.test.runOrder>filesystem</surefire.test.runOrder>
</properties>
....
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <runOrder>${surefire.test.runOrder}</runOrder>
  </configuration>
</plugin>
....

Then you may choose the setting you want at the command line:

mvn -Dsurefire.test.runOrder=failedfirst test (or package or whatever phase you want).
