exception.java：
import org.testng.annotations.Test; public class exception { @Test public void testMethod() { int a = 0; int b = 10; System.out.println(b / a); } } |
运行结果：

如果我们的预期结果就是代码抛出异常ArithmeticException，用例通过的话，则通过@Test的expectedExceptions属性，通过该属性指定抛出异常的类，
修改exception.java，添加(expectedExceptions = ArithmeticException.class)：
import org.testng.annotations.Test; public class exception { @Test(expectedExceptions = ArithmeticException.class) public void testMethod() { int a = 0; int b = 10; System.out.println(b / a); } } |
再次运行，结果通过：
PASSED: testMethod =============================================== Default test Tests run: 1, Failures: 0, Skips: 0 =============================================== |
如果是一个正常的代码，期望抛出异常的话，会怎样呢？
修改exception.java，不会抛出异常：
import org.testng.annotations.Test; public class exception { @Test(expectedExceptions = ArithmeticException.class) public void testMethod() { int a = 0; int b = 10; System.out.println(a / b); } } |
再次运行，结果失败：
