c# - 如何对 Web API 中冲突响应的错误消息进行单元测试

Question

这是我的端点:

public IHttpActionResult Work()
{
    try
    {
        this.Service.DoWork();
        return this.Ok();
    }
    catch (SomeException)
    {
        return this.Content(HttpStatusCode.Conflict, new { Message = "The message" });
    }
}

如何对错误消息进行单元测试？

这是一个测试模板:

[Test]
public void Work_Conflict()
{
    this.Service.Setup(x => x.DoWork()).Throws<SomeException>();
    var result = (<what goes here?>)this.MyController.Work();
    Assert.AreEqual("The message", <what goes here?>);
}

Answer 1

你快到了。

您需要将结果转换为从 ApiController 返回的实际类型并提取预期数据。

[Test]
public void Work_Conflict()
{
    this.Service.Setup(x => x.DoWork()).Throws<SomeException>();
    IHttpActionResult result = this.MyController.Work();
    var objectResult = result as ObjectResult;
    Assert.IsNotNull(objectResult);
    dynamic model = objectResult.Value;
    string actual = (string)model.Message;
    string expected = "The message";
    Assert.AreEqual(expected, actual);
}
