如何在Asp.net Core 1中创建请求进行测试

Question

在我的Asp.net core 1应用程序中，我具有使用以下方法的控制器：

[Microsoft.AspNetCore.Mvc.HttpPost()]
[Microsoft.AspNetCore.Mvc.RequireHttps]
public async System.Threading.Tasks.Task<Microsoft.AspNetCore.Mvc.IActionResult> Save()
{
    if (ModelState.IsValid)
    {
        try
        {
            var pass = Request.Form["password"].ToString();
            var pass1 = Request.Form["password1"].ToString();
            if (!pass.Equals(pass1))
            {
                return View("~/Views/PasswordRecovery.cshtml");
            }                  
        }
        catch (System.Exception ex)
        {
            return View("~/Views/Message.cshtml");
        }
    }
    return View("~/Views/Message.cshtml");
}

我想为此方法编写一个测试。 所以我写了这个：

[Xunit.Fact]
public async System.Threading.Tasks.Task SavePassNotEqualTest()
{
    var controller = new Controllers.PasswordRecoveryController(_mockRepo.Object);
    var dic = new System.Collections.Generic.Dictionary<string, Microsoft.Extensions.Primitives.StringValues>();
    dic.Add("password", "test");
    dic.Add("password1", "test1");
    var collection = new Microsoft.AspNetCore.Http.FormCollection(dic);
    controller.Request.Form = collection;  //request is null

    var result = await controller.Save();
    var viewResult = Xunit.Assert.IsType<Microsoft.AspNetCore.Mvc.ViewResult>(result);
    Xunit.Assert.Equal("~/Views/Message.cshtml", viewResult.ViewName);
}

问题是我需要将一些测试值设置为Form，Form在Request中，而Request为NULL。 我找不到，如何创建一些非NULL请求并用值填充它的Form。

编辑答案帮助我完成了以下解决方案：

我创建了一个将返回FormCollection的方法：

private Microsoft.AspNetCore.Http.FormCollection GetFormCollection()
{
    var dic = new System.Collections.Generic.Dictionary<string, Microsoft.Extensions.Primitives.StringValues>();
    dic.Add("password", "test");
    dic.Add("password1", "test1");
    return new Microsoft.AspNetCore.Http.FormCollection(dic);
}

我的测试方法是：

[Xunit.Fact]
public async System.Threading.Tasks.Task SavePassNotEqualTest()
{           
    var controller = new Findufix.Controllers.PasswordRecoveryController(_mockRepo.Object);

    var httpContext = new Moq.Mock<Microsoft.AspNetCore.Http.HttpContext>();
    httpContext.Setup( x => x.Request.Form).Returns(GetFormCollection());  

    controller.ControllerContext.HttpContext = httpContext.Object;          

    var result = await controller.Save();
    var viewResult = Xunit.Assert.IsType<Microsoft.AspNetCore.Mvc.ViewResult>(result);
    Xunit.Assert.Equal("~/Views/PasswordRecovery.cshtml", viewResult.ViewName);
}

Answer 1

使用Moq，您可以像这样：

var httpContext = new Mock<HttpContextBase>();           

httpContext.Setup(c => c.Request.Form).Returns(delegate()
{
    var formVaues = new NameValueCollection();
    formVaues .Add("Id", "123");
    formVaues .Add("Name", "Smith");

    return formVaues ;
});

如果将DefaultHttpContext传递给控制器​​，则Request不会为null，您可以将表单分配给Request.Form 。 无需嘲笑。

[Xunit.Fact]
public async System.Threading.Tasks.Task SavePassNotEqualTest()
{
    var controller = new Controllers.PasswordRecoveryController(_mockRepo.Object);
    var dic = new System.Collections.Generic.Dictionary<string, Microsoft.Extensions.Primitives.StringValues>();
    dic.Add("password", "test");
    dic.Add("password1", "test1");
    var collection = new Microsoft.AspNetCore.Http.FormCollection(dic);

    // Give the controller an HttpContext.
    controller.ControllerContext.HttpContext = new DefaultHttpContext();
    // Request is not null anymore.
    controller.Request.Form = collection;  

    var result = await controller.Save();
    var viewResult = Xunit.Assert.IsType<Microsoft.AspNetCore.Mvc.ViewResult>(result);
    Xunit.Assert.Equal("~/Views/Message.cshtml", viewResult.ViewName);
}

在Moq中，您可以尝试使用Setup（）或SetupGet（）来教它返回所需的内容

类似于

controller.SetupGet(x => x.Request.Form).Returns(collection);
