我尝试测试在尝试登录新用户时是否抛出badcredationals和disableexception。控制器中的代码是：

@PostMapping("/login")
  public ResponseEntity<?> createAuthenticationToken(@RequestBody JwtRequest authRequest) {
    final String token;

    authenticate(authRequest.getUserName(), authRequest.getPassword());

    final MyUserDetails userDetails = userService.loadUserByUsername(authRequest.getUserName());
    token = jwtTokenUtil.generateToken(userDetails);

    return ResponseEntity.ok(new JwtResponse(token));
  }

  private void authenticate(String username, String pass) throws BadCredentialsException, DisabledException{
    try{

      authManager.authenticate(new UsernamePasswordAuthenticationToken(username,pass));
    }catch(DisabledException e){
      throw new DisabledException("User disabled");
    }catch(BadCredentialsException e){
      throw new BadCredentialsException("Wrong Username or password");
    }
  }

测试代码为：

@Test(expected = BadCredentialsException.class)
  public void shouldThrowBadCredentialsExceptionWhenTryToAuthWithBadCredential() throws Exception {
    JwtRequest jwtRequest = new JwtRequest("someUser", "somPass");

    when(authManager.authenticate(new UsernamePasswordAuthenticationToken("someUsername", "somePassword")))
        .thenThrow(new BadCredentialsException("bad credentials"));

    controller.createAuthenticationToken(jwtRequest);

    verify(service, never()).loadUserByUsername("some");

  }

}

@Test(expected = DisabledException.class)
  public void shouldThrowDisabledExceptionWhenTryToAuthWithDisabledUser() {
    JwtRequest jwtRequest = new JwtRequest("someUser", "somPass");

    when(authManager.authenticate(new UsernamePasswordAuthenticationToken("someUsername", "somePassword")))
        .thenThrow(new DisabledException("User_disabled"));

    controller.createAuthenticationToken(jwtRequest);

    verify(service, never()).loadUserByUsername("some");

当我尝试运行测试时，我总是得到下面的错误消息

java.lang.AssertionError: Expected exception: org.springframework.security.authentication.DisabledException

我现在知道如何解决这个问题了，有人能帮我解释一下问题是什么吗？谢谢
