我正在尝试测试使用异步的web api方法,但它们永远不会返回结果。
以下是控制方法:
[HttpGet]
[Route("{id}")]
[ResponseType(typeof(IEmployee))]
public async Task<IHttpActionResult> Get(string id)
{
try
{
IEmployee result = await _repoEmployee.GetEmployeeAsync(id);
return Ok(result);
}
catch (Exception ex)
{
logit.Error($@"An error occurred while trying to get Employee for Employee number ""{id}"".", ex);
throw;
}
}
以下是使用NUnit的测试:
[TestCase("0677")]
public async Task EmployeeController_Get_GiveValidEmpID_Success(string employeeNumber)
{
Setup();
// Act
IHttpActionResult getResult = await _controller.Get(employeeNumber);
var contentResult = getResult as NegotiatedContentResult<IEmployee>;
// Assert
Assert.IsNotNull(contentResult);
Assert.AreEqual(HttpStatusCode.Accepted, contentResult.StatusCode);
Assert.IsNotNull(contentResult.Content);
Assert.AreEqual(employeeNumber, contentResult.Content.Person.EmployeeNumber);
}
如果我调试Get方法,结果变量中会出现正确的结果,但是当它返回测试方法时,getResult就不算什么了。
我哪里出错了,如何修复它以测试结果?
谢谢!
答案 0 :(得分:2)
由于getResult
不属于NegotiatedContentResult<IEmployee>
类型,因此广告系列会为contentResult
生成空值。相反,您可能希望转换为OkNegotiatedContentResult<IEmployee>
:
var contentResult = getResult as OkNegotiatedContentResult<IEmployee>;
