500 Error Running Visual Studio ASP.NET Unit Test

Question

I have the following method in my unit test project: ``` [TestMethod] [HostType("ASP.NET")] [UrlToTest("http://localhost:3418/Web/SysCoord/ChooseEPA.aspx")] [AspNetDevelopmentServerHost("%PathToWebRoot%")] public void TestMethod1() { Page page = TestContext.RequestedPage; Assert.IsTrue(false, "Test ran, at least."); } ``` I'm getting this exception: The test adapter 'WebHostAdapter' threw an exception while running test 'TestMethod1'. The web site could not be configured correctly; getting ASP.NET process information failed. Requesting 'http://localhost:3418/SysCoord/VSEnterpriseHelper.axd' returned an error: The remote server returned an error: (404) Not Found. The remote server returned an error: (404) Not Found. The page works as it should in a browser at the url: http://localhost:3418/Web/SysCoord/ChooseEPA.aspx. This physical path is: C:\ESI\HR_Connect2\BenefitChangeSystem\Application_DEV\Web\SysCoord. Any ideas would be appreciated. Update 1 Added the following to my web.config…

I've had this problem before and at that point gave up after reading all I could google about it (including this thread).

The solution turned out to be simple in my case. All I had to do was not use ASP.NET test attributes and simply test the MVC project as a DLL.

Step 1

Remove the extra attributes from the test.

```
[TestMethod]
public void TestMethod1()
{
    Page page = TestContext.RequestedPage;
    Assert.IsTrue(false, "Test ran, at least.");
}
```

Step 2

In Code Coverage, uncheck the MVC Project and add the MVC Project's DLL manually.

Voila, it get instrumented as a normal assembly, no errors, doesn't spin up the Development Server, also doesn't fail the Team Build.
