.net core Url.Action mock,怎么样？

Question

如何在测试控制器动作期间模拟Url.Action？

我正在尝试对我的asp.net核心控制器操作进行单元测试.行动逻辑有Url.Action,我需要模仿它来完成测试,但我找不到正确的解决方案.

谢谢您的帮助!

更新 这是我需要测试的控制器中的方法.

    public async Task<IActionResult> Index(EmailConfirmationViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = await _userManager.FindByNameAsync(model.Email);

            if (user == null) return RedirectToAction("UserNotFound");
            if (await _userManager.IsEmailConfirmedAsync(user)) return RedirectToAction("IsAlreadyConfirmed");

            var token = await _userManager.GenerateEmailConfirmationTokenAsync(user);
            var callbackUrl = Url.Action("Confirm", "EmailConfirmation", new { userId = user.Id, token }, HttpContext.Request.Scheme);

            await _emailService.SendEmailConfirmationTokenAsync(user, callbackUrl);

            return RedirectToAction("EmailSent");
        }

        return View(model);
    }

我有嘲笑这部分的问题:

var callbackUrl = Url.Action("Confirm", "EmailConfirmation", new { userId = user.Id, token }, HttpContext.Request.Scheme);

最后我找到了解决方案

当您模拟UrlHelper时,您只需要模拟基本方法Url.Action(UrlActionContext context),因为所有帮助方法实际上都使用它.

        var mockUrlHelper = new Mock<IUrlHelper>(MockBehavior.Strict);
        mockUrlHelper
            .Setup(
                x => x.Action(
                    It.IsAny<UrlActionContext>()
                )
            )
            .Returns("callbackUrl")
            .Verifiable();

        _controller.Url = mockUrlHelper.Object;

也!因为HttpContext.Request.Scheme中的null,我有问题.你需要模拟HttpContext

_controller.ControllerContext.HttpContext = new DefaultHttpContext();
