如果test1()失败了怎么办?test2()测试会发生什么,因为它依赖于test1?
如果我们在test1()方法上不使用@Test注释,但在test 2()测试用例上仍然使用@Test(dependsOnMethod =“test1”),会怎么样?
如果我们在dependsOnMethods属性中传递一个方法列表会怎么样?他们的处决有命令吗?
如何在属于不同类的测试用例上使用dependsOnMethods?
本文将详细讨论@Test注释的dependsOnMethods属性。
这个属性有什么作用?dependsOnMethods属性的用途是什么?dependsOnMethods用于依赖于另一个测试用例执行的测试用例。因此,后一个测试用例将首先执行,因为它的执行对于运行依赖于它的用例是必要的。
语法
dependsOnMethod属性将接受一个字符串数组,如{“test1”,“test 2”},如果一个测试只依赖于另一个测试,你也可以传递“test1”。所以,它会像下面这样-
@Test(dependsOnMethod = {"test1","test2"}) // if depends on one or more tests
@Test(dependsOnMethod = "test1") // if your test depends on only one other test
现在,让我们看一些关于如何在测试中使用dependsOnMethods的代码-
import org.testng.Assert;
import org.testng.annotations.Test;public class CodekruTest {@Test // this test will run firstpublic void test1() {System.out.println("test1 is passed");Assert.assertTrue(true);}@Test(dependsOnMethods = "test1") public void test2() {System.out.println("test2 is passed");Assert.assertTrue(true);}}
产出-
test1 is passed
test2 is passed
PASSED: test1
PASSED: test2===============================================Default testTests run: 2, Failures: 0, Skips: 0
===============================================
在这里,您可以看到首先执行test1(),然后执行test2()。现在,让我们玩一些事情,因为许多紧迫的问题仍然没有答案。

如果test1()失败了怎么办?test2()测试会发生什么,因为它依赖于test1?
在这种情况下,test 2()将被跳过,不会运行。我们来看看这个的实际效果-
import org.testng.Assert;
import org.testng.annotations.Test;public class CodekruTest {@Testpublic void test1() {System.out.println("test1 is passed");Assert.assertTrue(false); // failing the condition here}@Test(dependsOnMethods = "test1") // now this test won't run as test1 failedpublic void test2() {System.out.println("test2 is passed");Assert.assertTrue(true);}}
产出-
test1 is passed

如果我们在test1()方法上不使用@Test注释,但在test 2()测试用例上仍然使用@Test(dependsOnMethod =“test1”),会怎么样?
它将抛出一个错误,并且任何一个测试用例都不会运行,如下所示-
import org.testng.Assert;
import org.testng.annotations.Test;public class CodekruTest {public void test1() {System.out.println("test1 is passed");Assert.assertTrue(true);}@Test(dependsOnMethods = "test1")public void test2() {System.out.println("test2 is passed");Assert.assertTrue(true);}}

如果我们在dependsOnMethods属性中传递一个方法列表会怎么样?他们的处决有命令吗?
不,没有测试的执行顺序,所以,如果我们通过一个测试列表,如@Test(dependsOnMethods = {“test1″,“test 2”}). TestNG可以先执行test1或test 2,但可以保证它们将在使用dependsOnMethods属性的测试方法之前运行。
如何在属于不同类的测试用例上使用dependsOnMethods?
我们可以通过在dependsOnMethods属性中给出方法名的完整路径来实现。让我们创建两个不同的类,CodekruTestFirst和CodekruTestSecond,每个类都有自己的测试用例。CodekruTestFirst的测试用例依赖于CodekruTestSecond的测试用例。
CodekruTestFirst.java
import org.testng.Assert;
import org.testng.annotations.Test;public class CodekruTestFirst {@Test()public void testFirst() {System.out.println("Excecuting test method in CodekruTestFirst class");Assert.assertTrue(true);}}
CodekruTestSecond.java
import org.testng.Assert;
import org.testng.annotations.Test;public class CodekruTestSecond {@Test(dependsOnMethods = "Demo.CodekruTestFirst.testFirst")public void testSecond() {System.out.println("Excecuting test method in CodekruTestSecond class");Assert.assertTrue(true);}}
我们现在将运行CodekruTestSecond类,并且CodekruTestFirst中的测试用例也将被执行,因为testSecond()方法依赖于它。

注意事项: 依赖方法和依赖方法必须具有不同的名称。否则,您将遇到错误。
public class CodekruTestFirst {@Testpublic void test() {System.out.println("Excecuting test method in CodekruTestFirst class");Assert.assertTrue(true);}}
public class CodekruTestSecond {@Test(dependsOnMethods = "Demo.CodekruTestFirst.test")public void test() {System.out.println("Excecuting test method in CodekruTestSecond class");Assert.assertTrue(true);}}
现在,当我们运行CodekruTestSecond类时,我们会得到下面的错误。
