无法在Visual Studio 2012中运行Windows应用商店应用的单元测试

Question

I can't seem to run unit tests for Windows store apps using Visual Studio 2012.

I have gone through the following steps in order to configure my application.

1. I create a windows store project. I build it and get it to run just fine.
2. I than right click on the solution and click Add > New Project. From the 'Add New Project Menu' I select the project template 'Unit Test Library (Windows Store apps) and click okay creating the project.
3. I create a basic unit test that looks something like the following.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.VisualStudio.TestPlatform.UnitTestFramework;

namespace UnitTestLibrary1
{
  [TestClass]
  public class UnitTest1
  {
    [TestMethod]
    public void TestMethod1()
    {
      string a = "a";
      string b = "b";

      Assert.AreEqual(a, b);
    }
  }
}

**Note as per the instructions found on the MSDN website here I have not built the Unit Test project yet

4 - I open the Visual Studio test explore which displays the following.

5 - I proceed to build the entire solution (below is the build output)

1>------ Build started: Project: vevo.pushclient, Configuration: Debug Any CPU ------
2>------ Build started: Project: UnitTestLibrary1, Configuration: Debug Any CPU ------
2>  UnitTestLibrary1 -> C:\Source\simple_push_client\vevo.pushclient\UnitTestLibrary1\bin\Debug\UnitTestLibrary1.dll
1>  vevo.pushclient -> C:\Source\simple_push_client\vevo.pushclient\vevo.pushclient\bin\Debug\vevo.pushclient.exe
========== Build: 2 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

The following was the output from Tests, I tried googling the error but could not find any helpful answers

------ Discover test started ------
MSTestAdapter failed to discover tests in class 'UnitTestLibrary1.UnitTest1' of assembly 'C:\Source\simple_push_client\vevo.pushclient\UnitTestLibrary1\bin\Debug\UnitTestLibrary1.dll'. Reason Method not found: 'System.String Microsoft.VisualStudio.TestPlatform.UnitTestFramework.TestCategoryBaseAttribute.get_TestCategory()'..
NUnit 0.97.0.0 discovering tests is started
NUnit 0.97.0.0 discovering test is finished
========== Discover test finished: 0 found (0:00:00.1800223) ==========

The Test Explorer still showed the same message as before the build that stated 'Build your solution to discover all available tests....

Even so I tried clicking run all.

This resulted in the following output for the build

========== Build: 0 succeeded, 0 failed, 2 up-to-date, 0 skipped ==========

And no output for Tests

Needless to say no tests were shown as having been run, passed, skipped, or failed in the test explorer.

I ensured that the configuration Properties of the UnitTest project were set to build and deploy and attempted to build using each platform configuration (Any CPU, x86, and x4)

Answer 1

It tells you that you are missing an attribute on your test methods...

MSTestAdapter failed to discover tests in class 'UnitTestLibrary1.UnitTest1' of assembly 'C:\\Source\\simple_push_client\\vevo.pushclient\\UnitTestLibrary1\\bin\\Debug\\UnitTestLibrary1.dll'. Reason Method not found: 'System.String Microsoft.VisualStudio.TestPlatform.UnitTestFramework.TestCategoryBaseAttribute.get_TestCategory()'..

Not sure why, it shouldn't be required. But add the attribute:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.VisualStudio.TestPlatform.UnitTestFramework;

namespace UnitTestLibrary1
{
  [TestClass]
  public class UnitTest1
  {
    [TestMethod]
    [TestCategory("tests")]    <! -- Added Attribute -->
    public void TestMethod1()
    {
      string a = "a";
      string b = "b";

      Assert.AreEqual(a, b);
    }
  }
}

The Category can be whatever you want. Not sure why its doing that, Category should be an optional parameter.
