grails單元測試中的@ExpectedException

Question

有人在grails單元測試中使用過這個注釋嗎？ 似乎沒有為我工作。 謝謝。 d

更新：我下面測試的最后一行確實拋出了預期的異常。 但是測試失敗了（這里的堆棧跟蹤太大......）。 我正在使用grails 1.2並在eclipse的junit runner中運行測試。 也許grails使用的是早期版本的junit而不是4？

/**
 * Get the EC by a manager of a different company. Should throw exception
 */
@ExpectedException(ServiceAuthorizationException.class)
void testGetEcByNonOwnerManagerOfDifferentCompany() {
    mockDomain(ExpenseClaim , [new ExpenseClaim(id:"1",narrative:"marksClaim", employee:userMark, company:dereksCompany)])      

    def authControl = mockFor(AuthenticateService)
    authControl.demand.userDomain(1..1)  {-> otherUserMgr }
    authControl.demand.ifAllGranted(1..1)  {String arg1 -> return "ROLE_COMPANYMANAGER".equals(arg1) } //returns true
    def testService = new ExpenseClaimService()
    testService.authenticateService = authControl.createMock()
    def thrown = false
    testService.getExpenseClaim("1")
}

目前僅支持JUnit 3，因此請使用shouldFail() ：

void testGetEcByNonOwnerManagerOfDifferentCompany() {

  shouldFail(ServiceAuthorizationException) {
    mockDomain(ExpenseClaim , [new ExpenseClaim(id:"1",
                               narrative:"marksClaim", employee:userMark,
                               company:dereksCompany)])      

    def authControl = mockFor(AuthenticateService)
    authControl.demand.userDomain(1..1)  {-> otherUserMgr }
    authControl.demand.ifAllGranted(1..1)  {String arg1 ->
       "ROLE_COMPANYMANAGER".equals(arg1) } //returns true
    def testService = new ExpenseClaimService()
    testService.authenticateService = authControl.createMock()
    testService.getExpenseClaim("1")
  }
}

shouldFail()實際上更方便，因為每次測試可以多次使用它，並且它返回異常消息，因此您可以根據消息和異常進行斷言。
