I tried several solutions provided in this thread  however they were not working for module which depends on a different one  In that case I had to run mvn from the root-module with additional parameters  -am  --also-make   which tells maven to built modules which your test module depends on and -DfailIfNoTests false  otherwise  quot No tests were executed  quot  error appears  mvn test -pl B -Dtest MyTestClass myTest -am -DfailIfNoTests false  pom xml section in root   lt modules gt       lt module gt A lt  module gt       lt module gt B lt  module gt   lt modules gt   B depends on A

You can run a single test class  but not a single method within a test class    You use the simple name of the class not the fully-qualified name of the class    So  if you have a test in  org sonatype test MyTest  and that is the only test you want to run  your command line would look like this   mvn test -Dtest MyTest

The test parameter mentioned by tobrien allows you to specify a method using a   before the method name  This should work for JUnit and TestNG  I ve never tried it  just read it on the Surefire Plugin page      Specify this parameter to run individual tests by file name  overriding the includes excludes parameters  Each pattern you specify here will be used to create an include pattern formatted like      test  java  so you can just type  -Dtest MyTest  to run a single test called  foo MyTest java     This parameter overrides the includes excludes parameters  and the TestNG suiteXmlFiles parameter  since 2 7 3 You can execute a limited number of method in the test with adding  myMethod or  my ethod  Si type  -Dtest MyTest myMethod  supported for junit 4 x and testNg

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  lt module-name gt    For integration tests use it test     option instead of test       mvn -pl  lt module-name gt  -Dit test TestCircle xyz integration-test
