C# 如何测试IActionResult及其内容

我正在用C#和.NETCore2.0开发一个ASP.NETCore2WebAPI

我更改了一个方法，将其添加到try-catch中，以允许我返回状态代码

public IEnumerable<GS1AIPresentation> Get()
{
    return _context
        .GS1AI
        .Select(g => _mapper.CreatePresentation(g))
        .ToList();
}

但是现在我的测试方法有一个问题，因为现在它返回的是

IActionResult

，而不是

IEnumerable

：

或者我可以在

IActionResult

中获取

IEnumerable

，在控制器中调用的

返回Ok（…）

返回a，它是从

IActionResult

派生的，因此您需要转换为该类型，然后访问其中的值

[Test]
public void ShouldReturnGS1Available() {
    // Arrange
    MockGS1(mockContext, gs1Data);

    var controller = new GS1AIController(mockContext.Object, mockMapper.Object);

    // Act
    IActionResult result = controller.Get();        

    // Assert
    var okObjectResult = result as OkObjectResult;
    Assert.IsNotNull(okObjectResult);
    var presentations = okObjectResult.Value as IEnumerable<Models.GS1AIPresentation>;
    Assert.IsNotNull(presentations);
    Assert.AreEqual(presentations.Select(g => g.Id).Intersect(gs1Data.Select(d => d.Id)).Count(),
                    presentations.Count());
}

[测试]
public void应返回GS1可用（）{
//安排
MockGS1（mockContext，gs1Data）；
var controller=new GS1AIController（mockContext.Object、mockMapper.Object）；
//表演
IActionResult=controller.Get（）；
//断言
var okObjectResult=结果为okObjectResult；
Assert.IsNotNull（okObjectResult）；
var presentations=okObjectResult.Value作为IEnumerable；
Assert.IsNotNull（演示文稿）；
Assert.AreEqual（presentations.Select（g=>g.Id）.Intersect（gs1Data.Select（d=>d.Id））.Count（），
Count（））；
}
