testNG异常测试只程序本身会抛出某个异常，期望结果和抛出的异常一致，则测试通过，如果不一致则失败。
代码如下
package com.course.testng;
import org.testng.annotations.Test;
public class ExpectedException {
/**
* 什么时候会用到异常测试？
* 在我们期望结果为某个异常的时候
* 比如：我们传入了某些不合法的参数，程序抛出了异常
* 也就是期望结果结果就是这个异常
*/
/**
* 异常测试失败，抛出的异常和期望结果ArithmeticException不符
*/
@Test(expectedExceptions = ArithmeticException.class)
public void runTimeExceptionFail() {
System.out.println("这应该抛出一个RuntimeException异常");
throw new RuntimeException();
}
/**
* 异常测试成功
*/
@Test(expectedExceptions = ArithmeticException.class)
public void divisionWithException() {
int i = 1 / 0;
System.out.println("这是一个成功的异常测试");
}
}
运行结果
