TestNg的依赖测试

 有时在测试的过程中,有些测试方法要依赖于另外测试方法的执行成功,testng支持这种依赖关系的

TestNg的依赖关系

 testNg允许指定依赖关系,如果依赖关系失败了,则跳过后面的所有方法.
 在@Test注释中使用属性dependsOnMethods，或者在@Test注释中使用属性dependsOnGroups。

示例代码dependsOnMethods

一个简单的method2依赖于method1

public class TestNgDemo4 {

@Test
public void test_method(){
    System.out.println("第一个测试方法");
}

@Test(dependsOnMethods = {"test_method"})
public void test_method1(){
    System.out.println("第二个测试方法");
}
}
执行结果:
第一个测试方法
第二个测试方法

如果method1失败了,则不执行method2

 public class TestNgDemo4 {

@Test
public void test_method(){
    System.out.println("第一个测试方法");
    throw new RuntimeException();
}

@Test(dependsOnMethods = {"test_method"})
public void test_method1(){
    System.out.println("第二个测试方法");
}
}
 执行结果:
 第一个测试方法

dependsOnGroups 的操作

 编写2个测试脚本,分别叫testBase,testTwo,其中testTwo依赖于testbase的方法

testBase.java的代码示例:

 import org.testng.annotations.Test;

@Test(groups = "deploy")
public class testBase {
@Test
 public void deployServer() {
    System.out.println("Deploying Server...");
 }

 @Test(dependsOnMethods = "deployServer")
 public void deployBackUpServer() {
    System.out.println("Deploying Backup Server...");
 }

}

testtwo.java代码:

import org.testng.annotations.Test;

public class testTwo {

@Test(dependsOnGroups = "deploy")
public void test_001(){
    System.out.println("依赖方法的测试");
}
}

点击运行测试,测试结果如下:

Deploying Server...
Deploying Backup Server...
