How to run Maven surefire without printing out test results to the command line?

Question

I am running the Maven 3.1.0 Surefire plugin already with the --quiet option, however it still prints out the results of unit tests out to the command line, even if they all pass. Is there a way to only get it to print failures?

The output I'd like to suppress if everything is fine looks like:

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running net.initech.project.dawgs.actionfactory.InterfaceActionFactoryTest
Tests run: 14, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.425 sec

Running net.initech.project.assertion.AssertStartsWithTest
Tests run: 6, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.008 sec

Results :

Tests run: 52, Failures: 0, Errors: 0, Skipped: 0

No, I do not want to pipe the output to /dev/null

Glad someone asked this. I wish maven defaults didn't produce this diarrhea. – Roumell

Answer 1

Try setting the surefire.printSummary property to false: this should only print the test cases that have errors. So try running it as mvn -q -Dsurefire.printSummary=false.

Alternatively, you can put it in your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>            
      <printSummary>false</printSummary> 
    </configuration>
  </plugin>

This still prints the "----<br>TESTS----<br>" banner, any idea how to get rid of that? I'm tempted to file that as a feature request against SureFire since it seems it ought to be included in that option. – Fluff

One more caveat that fooled me: if your command has -Dsurefire.useFile=false, then the setting of -Dsurefire.printSummary=false will not be respected. – Roumell

Another caveat - inside a pluginManagement element this setting seems to get ignored. – Roumell

And another caveat - if you have printSummary=false, then <trimStackTrace>false</trimStackTrace> will not be respected – Evergreen
