tdd - 使用 Moq 使用 ActionMailer.net 模拟 MailController

Question

我正在尝试模拟我的 MailController

_mockMailController = new Mock<IMailController>();
_mockMailController.Setup(x => x.ForgotPassword("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="deaabbadaa9ebbb3bfb7b2f0bdb1b3" rel="noreferrer noopener nofollow">[email protected]</a>"));

我的 Controller 将 IMailController 作为依赖项，但是当我调用时

mailController.ForgotPassword("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c6b2a3b5b286a3aba7afaae8a5a9ab" rel="noreferrer noopener nofollow">[email protected]</a>").Deliver();

我收到 NullReferenceException(我猜是因为 ForgotPassword 没有返回任何内容)

理想情况下，我们会 stub EmailResult？

我为 ActionMailer.Net 创建了一个拉取请求，该请求引入了 IEmailResult 接口(interface)，使模拟变得非常容易。看看这个:

https://bitbucket.org/swaj/actionmailer.net/pull-request/4/iemailresult-interface-for-better/

在合并拉取请求之前，您可以使用我项目中的自定义构建。

https://bitbucket.org/hydr/xv-actionmailer.net

模拟 get 就像写作一样简单(使用 FakeItEasy，Moq 可能类似):

//SetUp
_myMailer = A.Fake<IMyMailer>();

//Later on in Assert
A.CallTo(() => _myMailer.MyTestEmail()).MustHaveHappened(Repeated.Exactly.Once);

当 Mailer 定义如下时:

public class MailController : MailerBase, IMyMailer
{
    public IEmailResult MyTestEmail()
    {
        To.Add("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="87f5e2e4eef7eee2e9f3c7f4e3e1a9e4e8ea" rel="noreferrer noopener nofollow">[email protected]</a>");
        From = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6211070c060710221106044c010d0f" rel="noreferrer noopener nofollow">[email protected]</a>";
        Subject = "Subject";
        return Email();
    }
}
