testNG依赖测试是指一个用例需要依赖另外一个用例才能运行，只有运行成功后才会执行，如果被依赖的用例执行失败，那边这个用例将会Skips掉。
以下代码运行结果
Total tests run: 4, Failures: 1, Skips: 1
java代码如下
1 package com.course.testng; 2 3 import org.testng.annotations.Test; 4 5 public class DependTest { 6 /** 7 * 依赖测试 8 */ 9 // test1 可以作为test2的前置条件 10 @Test 11 public void test1() { 12 System.out.println("这是test1运行"); 13 } 14 15 /** 16 * 可以成功运行，因为test1（)能运行成功 17 */ 18 @Test(dependsOnMethods = {"test1"}) 19 public void test2() { 20 System.out.println("这是test2运行"); 21 22 } 23 24 /** 25 * 异常测试失败，抛出的异常和期望结果ArithmeticException不符 26 */ 27 @Test(expectedExceptions = ArithmeticException.class) 28 public void runTimeExceptionFail() { 29 System.out.println("这应该抛出一个RuntimeException异常"); 30 throw new RuntimeException(); 31 32 } 33 34 /** 35 * 这个用例会因runTimeExceptionFail（）运行失败，而Skips 36 */ 37 @Test(dependsOnMethods = {"runTimeExceptionFail"}) 38 public void test3() { 39 System.out.println("这个用例会因runTimeExceptionFail（）运行失败，而Skips"); 40 41 } 42 43 }
运行结果
