The differences between JUnit 3 and JUnit 4

Question

Could someone describe in a few words what the main differences between JUnit 3 and 4 are?

This is not actually a question of opinion. There are very factual and explicit differences between Junit 3 and 4 and the enumeration of such is of interest. — dcow, Dec 22 '14 at 22:32

Java 5 annotations for setup and teardown (@before and @after) instead of setUp() and tearDown().
don't need to extend TestCase anymore.
@Test annotation replaces testSomeMethod() naming convention.
static imports for asserts.
Junit theories, which allow you to separate data sets from the test itself.

one more.. names doesn't need to start with "test" therefore pattern "testXXXXX" can be ignored with JUnit4. – Ewoks Aug 24 '15 at 13:36
