Junit处理异常

当一个被测类中有异常时,如何处理?

如:一个原始的被测类;

  public class UserExceptionDemo {
    public int age;
    public String name;
    public void setAge(int age){
      if(age<0||age>100){
      throw new IllegalArgumentException("ageError!");
      }
    System.out.println(age);
    }
  }

 

junit测试类应该这么写:

  public class UserExceptionDemoTest {
    @Test(expected = IllegalArgumentException.class)
    public void testSetAge() {
      UserExceptionDemo user = new UserExceptionDemo();
      user.setAge(-1);
    }
  }
