java - @BeforeClass 方法不在每节课之前运行

Question

我有两个类，每个类包含 2 个测试用例和 Test1 类，其中一个方法带有 @BeforeClass，按照我的说法，这个方法也应该在 Test2 类之前运行，但它没有运行。

    package WebPackage;

    import org.testng.annotations.BeforeClass;
    import org.testng.annotations.Test;

    public class Test1 {
        @BeforeClass
        public void test1() {

            System.out.println("printing Before Class Method");
        }
        @Test (priority = 1)
    public void test2() {

            System.out.println("printing test_2");
        }

        @Test (priority = 3)
    public void test3() {

            System.out.println("printing test_3");
        }
    }

测试2

    package WebPackage;

    import org.testng.annotations.Test;

    public class Test2 {

        @Test (priority = 1)
        public void test4() {

                System.out.println("printing test_4");
            }

            @Test (priority = 3)
        public void test5() {

                System.out.println("printing test_5");
            }
    }

Answer 1

您可以使用 @BeforeClass 注释创建一个 BaseTest 类，然后每个测试类都使用 BaseTest 进行扩展。

基础测试:

public class BaseTest {
    @BeforeClass
    public void test1() {
        System.out.println("printing Before Class Method");
    }
}

测试 1:

public class Test1 extends BaseTest {
    @Test (priority = 1)
    public void test2() {
        System.out.println("printing test_2");
    }

    @Test(priority = 3)
    public void test3() {
        System.out.println("printing test_3");
    }
}

测试 2:

public class Test2 extends BaseTest {
    @Test(priority = 1)
    public void test4() {
        System.out.println("printing test_4");
    }

    @Test (priority = 3)
    public void test5() {
        System.out.println("printing test_5");
    }
}

输出:

printing Before Class Method
printing test_2
printing test_3
printing Before Class Method
printing test_4
printing test_5
