  1. Java 5 annotations for setup and teardown (@before and @after) instead of setUp() and tearDown().

  2. don't need to extend TestCase anymore.

  3. @Test annotation replaces testSomeMethod() naming convention.

  4. static imports for asserts.

  5. Junit theories, which allow you to separate data sets from the test itself.
