        private string getBaseViewPath()
        {
            return @"~\Views\Indications\TermSheetViews\";
        }
    }

因此，只需查看代码，您就可以知道它的作用。每个控制器动作引用一个不同的期望结果，我传入（大部分）Guid? id，我们正在使用id来调用private帮助器方法，获取model，并根据view返回特定的model。

我甚至不知道从哪里开始对这个班级进行单元测试。我可以在这里得到一些帮助吗？谢谢！

Answer 1

嗯，首先，您应该进行测试以确保传入的特定Guid会导致ViewResult具有正确的View位置集。 AKA

ActionResult action = _myControllerToTest.Notes(null, null);
Assert.IsNotNull(action);

ViewResult viewResult = action as ViewResult;
Assert.IsNotNull(viewResult);

// Check viewResult for correct view path and model data

从那里开始，并确保注入depdencies（特别是对于isModelValid（）方法，因为它调用了CachedTransactionManager）
