grails单元测试中的@ExpectedException

Question

有人在grails单元测试中使用过这个注释吗？似乎没有为我工作.谢谢.d

更新:我下面测试的最后一行确实抛出了预期的异常.但是测试失败了(这里的堆栈跟踪太大......).我正在使用grails 1.2并在eclipse的junit runner中运行测试.也许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")
}

目前仅支持JUnit 3,因此请shouldFail()改用:

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() 实际上更方便,因为每次测试可以多次使用它,它会返回异常消息,因此您可以根据消息和异常进行断言.
