I have 2 classes under src/test/java that I want to run: scen1.class and scen2.class. Both of these have @Test annotated methods.

I have another class called JunitDefinitions.class that has only @Before, @After, @BeforeClass and @AfterClass methods (no @Test). This is also under src/test/java but under a different package.

Assuming I have the default pom.xml, what should I add to it in order to be able to execute all these 3 classes?

  • Doesn't `mvn install` execute them? What exactly are you looking for? – Mureinik May 27 '17 at 11:32
  • You should have junit as dependency with scope`test` in your pom file and usually this should simply run by: `mvn clean test` – khmarbaise May 27 '17 at 11:32

    AFAIK the test classes must follow the pattern `*Test.java`. Hence, rename your classes to `Scen1Test` respectively `Scen2Test`. Related: [How do I get my Maven Integration tests to run](https://stackoverflow.com/q/1399240/3429133). – beatngu13 May 27 '17 at 11:44
  • I have the junit dependency there, where should i add scope test? Currently mvn clean test doesn't run the tests – Dotan Raz May 27 '17 at 11:46
  • Please show the full outline of your project and your pom file please...or put that example project on github so we can take a look at it... – khmarbaise May 27 '17 at 12:45

  • BTW, if the nemes of the classes are Test1.class, Test2.class Maven runs them, but it doesn't run the class with the BeforeClass anotation, again, this class doesn't have Test anotation... – Dotan Raz May 27 '17 at 14:54

  • Rename your test classes to Scen1Test.java and Scen2Test.java or include JunitFW.java, Scen1.java and Scen2.java using <includes> configuration, as it's described in the documentation.
  • The class JunitFW only contains a @Before, so it's not detected as a Test. You have to move the @Before to a class containing @Test or include a @Test in JunitFW class and rename it to JunitFWTest to make it work.

By default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns:

"**/Test*.java" - includes all of its subdirectories and all Java filenames that start with "Test".
"**/*Test.java" - includes all of its subdirectories and all Java filenames that end with "Test".
"**/*Tests.java" - includes all of its subdirectories and all Java filenames that end with "Tests".
"**/*TestCase.java" - includes all of its subdirectories and all Java filenames that end with "TestCase".

  • thanks Viniciusartur, but still, Maven doesn't execute JunitFWTest.java... it has only a Before anotation and not Test anotation... – Dotan Raz May 27 '17 at 18:15
  • I tested it and you're right. I updated the answer: The class JunitFW only contains a `@Before`, so it's not detected as a Test. You have to move the `@Before` to a class containing `@Test` or include a `@Test` in JunitFW class and rename it to JunitFWTest to make it work. – viniciusartur May 27 '17 at 21:12

Apart from the renaming of your classes as something like Scen1Test.java and Scen2Test.java as suggested by @viniciusartur, which shall help Maven to recognize the test classes to execute them using surefire-plugin.

Another point to note here is that the reason due to which the @Before, @BeforeClass, @After etc are not executed independently without a @Test method is that only

The Test annotation tells JUnit that the public void method to which it is attached can be run as a test case. To run the method, JUnit first constructs a fresh instance of the class then invokes the annotated method.

From the documentation of @Before in JUnit

Annotating a public void method with @Before causes that method to be run before the Test method. The @Before methods of superclasses will be run before those of the current class.

So inferring as this, while annotations are processed, if there is no @Test annotation present in the class under /src/test/java(relative to the question based on maven), no further annotations are meaningful to be processed.

Just to note, if you extend this class with another SubClassTest.java consisting of a @Test method, all these methods would be executed then. Since they are processed based on what(@Test) to act on to.
