How to run test methods in specific order in JUnit4?

In JUnit 4, you can use the @FixMethodOrder annotation to specify the order in which test methods should be executed. The @FixMethodOrder annotation is available as a part of the org.junit.runners.MethodSorters class.

To use the @FixMethodOrder annotation, you need to specify one of the following values for the value parameter:

• MethodSorters.NAME_ASCENDING: This value specifies that test methods should be executed in alphabetical order.
• MethodSorters.JVM: This value specifies that test methods should be executed in the order they are returned by the JVM.

Here is an example of how to use the @FixMethodOrder annotation to specify the order in which test methods should be executed:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class MyTest {

    @Test
    public void testMethod1() {
        // test method implementation
    }

    @Test
    public void testMethod2() {
        // test method implementation
    }

    @Test
    public void testMethod3() {
        // test method implementation
    }

}

In this example, the test methods will be executed in alphabetical order.

I hope this helps. Let me know if you have any questions.
