(1) Create empty class FastTests and SlowTests. (2) In your test case class, categorize your test method using @Category annotation:
(3) Append the following code to your pom.xml:
SlowTests com.sap.SlowTests FastTests com.sap.FastTests org.apache.maven.plugins maven-compiler-plugin 3.1 1.8 1.8 org.apache.maven.plugins maven-surefire-plugin 2.13 org.apache.maven.surefire surefire-junit47 2.13 ${testcase.groups}
(4) In my project, by default all 7 test methods will be executed during Maven build:
Suppose you only want to execute unit test belonging to category “SlowTests”, use the following command line:

Since now I only marked one method with annotation SlowTests, only one test method is executed:
If you would like to execute all unit tests EXCEPT @SlowTests, simply add another profile in pom.xml:
NonSlowTests org.apache.maven.plugins maven-surefire-plugin com.sap.SlowTests
Before test, in order to prove that Slow method is NOT really executed, I add a system.out.println in each method:
Use command line: mvn test -P NonSlowTests From console output, I can ensure that the method with @Category(SlowTests.class) is NOT executed at all.
