單元測試ApiController方法和狀態碼不HttpStatusCode枚舉

Question

我有一個看起來像這樣的ApiController方法...

[HttpPost] 
    public IHttpActionResult Post([FromBody] GloballyEnumeratedMessage gem) 
    { 
     var result = _gemPublisher.PublishGem(gem); 

     if (result.Success) 
     { 
      return Ok(); 
     } 

     return new StatusCodeResult((HttpStatusCode)422, this); 
    } 

我的測試，用於檢查好結果如下。

[TestMethod] 
    public void Post_ValidGem_Returns200() 
    { 
     _gemPublisherMock.Setup(v => v.PublishGem(It.IsAny<GloballyEnumeratedMessage>())).Returns(ResultStatus.FromSuccess()); 

     var controller = new PublishGemController(_gemPublisherMock.Object); 

     // Act 
     IHttpActionResult actionResult = controller.Post(It.IsAny<GloballyEnumeratedMessage>()); 

     // Assert 
     Assert.IsInstanceOfType(actionResult, typeof(OkResult)); 
    } 

我返回422之前，我是返回一個錯誤請求和測試是這樣的：

[TestMethod] 
    public void Post_InvalidGem_Returns400() 
    { 
     _gemPublisherMock.Setup(v => v.PublishGem(It.IsAny<GloballyEnumeratedMessage>())).Returns(ResultStatus.FromFailure()); 

     var controller = new PublishGemController(_gemPublisherMock.Object); 

     // Act 
     IHttpActionResult actionResult = controller.Post(It.IsAny<GloballyEnumeratedMessage>()); 

     // Assert 
     Assert.IsInstanceOfType(actionResult, typeof(BadRequestResult)); 
    } 

我想保留錯誤請求另一個潛在的故障，從而決定改變郵政法如果發佈失敗，則返回422。我的測試將檢查422狀態碼是什麼樣的？

編輯：解決了基於關閉的問題

[TestMethod] 
public void Post_InvalidGem_Returns422() 
{ 
    _gemPublisherMock.Setup(v => v.PublishGem(It.IsAny<GloballyEnumeratedMessage>())).Returns(ResultStatus.FromFailure()); 

    var controller = new PublishGemController(_gemPublisherMock.Object); 

    // Act 
    IHttpActionResult actionResult = controller.Post(It.IsAny<GloballyEnumeratedMessage>()); 
    var result = (StatusCodeResult) actionResult; 

    // Assert 
    Assert.IsInstanceOfType(actionResult, typeof(StatusCodeResult)); 
    Assert.AreEqual(422, (int)result.StatusCode); 
}

以下控制器和測試註釋做什麼，我相信你想要完成的任務：

控制器：

public class MyTestController : ApiController 
{ 
    [HttpPost] 
    public IHttpActionResult Post([FromBody] object gem) 
    { 
     return new StatusCodeResult((HttpStatusCode)422, this); 
    } 
} 

測試：

[TestMethod] 
    public void Post_Returns422() 
    { 
     var controller = new MyTestController(); 

     // Act 
     IHttpActionResult actionResult = controller.Post(It.IsAny<object>()); 

     // Assert 
     Assert.IsInstanceOfType(actionResult, typeof(StatusCodeResult)); 
     Assert.AreEqual((int)((StatusCodeResult)actionResult).StatusCode,422); 
    }
