Run a single test method with maven

I know you can run all the tests in a certain class using:

mvn test -Dtest=classname

But I want to run an individual method and -Dtest=classname.methodname doesn't seem to work.

Solution 1:

To run a single test method in Maven, you need to provide the command as:

mvn test -Dtest=TestCircle#xyz test

where TestCircle is the test class name and xyz is the test method.

Wild card characters also work; both in the method name and class name.

If you're testing in a multi-module project, specify the module that the test is in with -pl <module-name>.

For integration tests use it.test=... option instead of test=...:

mvn -pl <module-name> -Dit.test=TestCircle#xyz integration-test

Solution 2:

There is an issue with surefire 2.12. This is what happen to me changing maven-surefire-plugin from 2.12 to 2.11:

1. mvn test -Dtest=DesignRulesTest

   Result:
   [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12:test (default-test) on project pmd: No tests were executed!

2. mvn test -Dtest=DesignRulesTest

   Result: [INFO] --- maven-surefire-plugin:2.11:test (default-test) @ pmd --- ... Running net.sourceforge.pmd.lang.java.rule.design.DesignRulesTest Tests run: 5, Failures: 0, Errors: 0, Skipped: 4, Time elapsed: 4.009 sec

Solution 3:

What I do with my TestNG, (sorry, JUnit doesn't support this) test cases is I can assign a group to the test I want to run

@Test(groups="broken")

And then simply run 'mvn -Dgroups=broken'.
