How to run a single JUnit test method in Eclipse? [duplicate]

Question

In a JUnit test case with multiple @Test annotations, how does one selectively run tests ?

For e.g., from the following code, how does one run just one test method ?

   @Test
   public void testHelloEmpty() 
   {
      assertEquals(h.getName(),"");
      assertEquals(h.getMessage(),"Hello!");
   }

   @Test
   public void testHelloWorld() 
   {
      // h.setName("World");
      assertEquals(h.getName(),"World");
      assertEquals(h.getMessage(),"Hello World!");
   }

I have tried to just highlight one @Test method and tried to run it, but it doesn't work that way.

Answer 1

For running a single test case in Eclipse (as per your last comment):

• Go to Run (the green forward arrow button) -> Run Configurations.
• Right click on JUnit, and select new.
• Fill in your test case and test method (the Search button is really helpful here).
• Click Run.

Answer 2

It seems that now days (Eclispse 4.4.0) this can be done easily.

If you place the caret at the head of the definition of a test case method, issue the Run or Debug command (menu or F11 or Ctrl+F11), then the JUnit plugin runs only that test case.

(If you on the other hand place the caret in the body of a method then all the test cases in that class are run.)

Some more tips for running JUnit tests:

• The Go to Previous/Next Member commands can be used to quickly move the caret to the head of the definition of a method with the keyboard. The default key bindings are Ctrl+Shift+Up/Down.
• If the Run or Debug commands are issued when the Debug, JUnit or Console views are active, then Eclipse will run the last run configuration. This can be used to re-run your single test case without having to navigate back to the editor.
• Running a particular run configuration can be done by navigating the Run menu: Alt + R, H, number key.
