How to set priority for test methods execution using Annotation?

Got annotation with priority:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Test {
    int priority();
}

Got test class:

  @Test(priority = 9)
    public static void test(){
        System.out.println("Test9");
    }

    @Test(priority = 8)
    public static void test1(){
        System.out.println("Test8");
    }

    @Test(priority = 7)
    public static void test2(){
        System.out.println("Test7");
    }
}

Got method to execute with priority, but it's not working:

for (Method m : methods){
        if (m.isAnnotationPresent(Test.class) && m.getAnnotation(Test.class).priority() == 9){
            m.invoke(null);
        }
        if (m.isAnnotationPresent(Test.class) && m.getAnnotation(Test.class).priority() == 8){
            m.invoke(null);
        }
        if (m.isAnnotationPresent(Test.class) && m.getAnnotation(Test.class).priority() == 7){
            m.invoke(null);
        }
    }

How to execute methods with priority?

CodePudding user response：

I guess, you are using junit library for testing. You can use @Order annotation

@Test
@Order(1)    
public void firstTest() {
    output.append("a");
}

@Test
@Order(2)    
public void secondTest() {
    output.append("b");
}

or in this documentation there are different ways to do this.
