How to run test methods in specific order in JUnit4?

Question

I want to execute test methods which are annotated by @Test in specific order.

For example:

public class MyTest {
    @Test public void          


        

Answer 1

JUnit since 5.5 allows @TestMethodOrder(OrderAnnotation.class) on class and @Order(1) on test-methods.

JUnit old versions allow test methods run ordering using class annotations:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
@FixMethodOrder(MethodSorters.JVM)
@FixMethodOrder(MethodSorters.DEFAULT)

By default test methods are run in alphabetical order. So, to set specific methods order you can name them like:

a_TestWorkUnit_WithCertainState_ShouldDoSomething b_TestWorkUnit_WithCertainState_ShouldDoSomething c_TestWorkUnit_WithCertainState_ShouldDoSomething

Or

_1_TestWorkUnit_WithCertainState_ShouldDoSomething _2_TestWorkUnit_WithCertainState_ShouldDoSomething _3_TestWorkUnit_WithCertainState_ShouldDoSomething

You can find examples here.
