c# - 起订量 应用变量

Question

这是我第一次使用最小起订量，并且无法真正找到有关如何将其用于应用程序变量的好教程。我在我的 Controller 中调用一个调用 HttpContext.Current.Application["TheConnectionString"] 的方法，并且在我的 global.asax 中声明并初始化 Application["TheConnectionString"] = "MyConnectionString “

[TestMethod]
public void TestGetCompanyList()
{
    string applicationValue = "MyConnectionString";
    var mockApplication = new Mock<HttpApplicationStateBase>();
    mockApplication.SetupSet(s => s["TheConnectionString"] = It.IsAny<string>()).Callback((string name) => applicationValue = (string)val);
    mockApplication.SetupGet(s => s["TheconnectionString"]).Returns(() => applicationValue);

    var request = new Mock<HttpRequestBase>();
    var context = new Mock<HttpContextBase>();

    request.SetupGet(x => x.Headers).Returns(new System.Net.WebHeaderCollection {{"X-Requested-With", "XMLHttpRequest"}});
    context.SetupGet(ctx => ctx.Request).Returns(request.Object);
    context.SetupGet(x => x.Application).Returns(applicationValue);


    var accController = new AccSerController();
    CInt cInt = new CInt();
    cIn.Iss = "Other";
    cIn.Tick = "BK";
    var result = accController.GetClist(cIn) as IEnumerable<CList>;
    Assert.IsNotNull(result);
}

我不知道如何将应用程序值“连接”到 Controller 。

编辑:

我的 Controller :

public class AccSerController : ApiController
{
    [System.Web.Http.HttpPost]
    public dynamic GetCList([FromBody]CompanyInput cInput)
    {
        AccSerFacade accService = new AccSerFacade();
        IEnumerable<CompanyListResult> cList = accService.GetCList(cIn);
        return cList;
    }

I in my controller i am calling a method that calls HttpContext.Current.Application["TheConnectionString"]

好的，我们应该从第一条规则开始:

HttpContext.Current == Arch Enemy Of Unit Testing. Search for every single occurrence of this static call in your application and get rid of it.

因此，如果您想有机会模拟和测试它，那么让我们通过将其替换为正确的抽象来删除 Controller 中的这个邪恶调用:

public ActionResult GetClist(CInt model)
{
    string conStr = (string)this.HttpContext.Application["TheConnectionString"];
    ...
}

现在您可以编写适当的单元测试:

// arrange
string applicationValue = "MyConnectionString";
var mockApplication = new Mock<HttpApplicationStateBase>();
mockApplication.SetupGet(s => s["TheConnectionString"]).Returns(applicationValue);

var request = new Mock<HttpRequestBase>();
var context = new Mock<HttpContextBase>();

request.SetupGet(x => x.Headers).Returns(new WebHeaderCollection { { "X-Requested-With", "XMLHttpRequest" } });
context.SetupGet(ctx => ctx.Request).Returns(request.Object);
context.SetupGet(ctx => ctx.Application).Returns(mockApplication.Object);

var sut = new AccSerController();
sut.ControllerContext = new ControllerContext(context.Object, new RouteData(), sut);

CInt cInt = new CInt();
cIn.Iss = "Other";
cIn.Tick = "BK";

// act
var actual = accController.GetClist(cIn);

// assert
Assert.IsNotNull(actual);
