blocks|key|1779460|text|不，您不能像这样测试视图。最接近的方法是将视图呈现到流编写器中，然后测试生成的HTML。这不是单元测试中通常要做的事情。我建议您执行web测试，以验证视图是否正确。您可以使用Visual+Studio创建web测试，也可以使用免费的Selenium框架。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1779461|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/ms182538%2528v=vs.80%2529.aspx|1|http://seleniumhq.org/^0|2F|D|0|38|8|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

No, you cannot test views like this. The closest you might get is to render the view into a stream writer and then test the generated HTML. It is not something that is commonly done in unit tests. I would recommend you performing web tests in order to verify that the views are correct. You could create web tests with <a href="http://msdn.microsoft.com/en-us/library/ms182538%28v=vs.80%29.aspx" rel="noreferrer">Visual Studio</a> or there's also the free <a href="http://seleniumhq.org/" rel="noreferrer">Selenium</a> framework.

blocks|key|1779471|text|控制器返回的ViewResult只有一个应该显示的视图的引用。此时甚至还没有解析该视图。那里的代码永远不会被你的测试执行。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1779472|您应该在控制器中设置ViewBag属性，而不是在视图中。通常，视图只读取这样的值。|1779473|希望能有所帮助|1779474|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

The ViewResult returned by a controller has only a reference to the view that should be shown. The view is not even resolved at this time. The code there is never executed by your test.

What you should do is set ViewBag properties in the controller, not the view. Usually, the view will only read such values.

hope it helps

blocks|key|1993155|text|由于ViewData和ViewBag使用相同的存储模式，因此您应该能够在测试中使用ViewData[yourKey]。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1993156|因此，您的测试将如下所示：|1993157|[TestCase]
public+void+About()
{
++++var+controller+=+new+AboutController();
++++var+ar+=+controller.About()+as+ViewResult;
++++Assert.AreEqual("About+Us",+ar.ViewData["Title"]);
}|code-block|syntax|javascript|1993158|entityMap^0|15|H|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|R|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|S|8|@]|D|@]|E|$K|L]]|$1|M|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|N|$]]

Since both the ViewData and ViewBag use the same storage pattern, you should be able to use <code>ViewData[yourKey]</code> in your tests.

So your test will look like this:

<pre><code>[TestCase]
public void About()
{
 var controller = new AboutController();
 var ar = controller.About() as ViewResult;
 Assert.AreEqual("About Us", ar.ViewData["Title"]);
}
</code></pre>

Have you tried

It works for me

blocks|key|1779525|text|不管它有什么价值，我发现以下方法工作得很好：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1779526|Assert.AreEqual(_layout,+result.ViewBag.Layout);|code-block|syntax|javascript|1779527|使用result作为ViewResult|offset|length|style|CODE|1779528|entityMap^0|0|0|2|6|A|A|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

For what its worth, I found that the following worked fine:

<pre><code>Assert.AreEqual(_layout, result.ViewBag.Layout);
</code></pre>

With <code>result</code> being the <code>ViewResult</code>

[TestMethod]

<pre><code> public async Task GetData() {
 CtrlNameController controller = new CtrlNameController();

 controller.ViewData["UserId"] = 1;

 ViewResult result = await controller.GetData() as ViewResult;

 Assert.IsNotNull(result);
}
</code></pre>

<code>ViewData["UserId"]</code> is equal to <code>View.UserId</code>

Say I have a view with the following code at the top of the page:

<pre><code>@{
 ViewBag.Title = "About Us";
 Layout = "~/Views/Shared/_Layout.cshtml";
}
</code></pre>

And I have a controller method:

<pre><code> public ActionResult About()
 {
 return View();
 }
</code></pre>

How can I test that the ViewBag was set properly?

I have tried the following code.

<pre><code>[TestCase]
public void About()
{
 var controller = new AboutController();
 var ar = controller.About() as ViewResult;
 Assert.AreEqual("About Us", ar.ViewBag.Title);
}
</code></pre>

But I get the following result when I run the test:

<pre><code>Tests.Controllers.AboutControllerTests.About():
 Expected: "About Us"
 But was: null
</code></pre>

Is there a way to unit test ASP.NET MVC ViewBag properties set in the view?

单元测试

假设我在页面顶部有一个包含以下代码的视图：@{    ViewBag.Title = "About Us";    Layout = "~/Views/Shared/_Layout.cshtml";}我有一个控制器方法：    public ActionResult About()    {        return...
