How can I run xUnit Unit Tests with VS2015 Preview

Question

I added the "xUnit.net runner for Visual Studio" v0.99.8 via Extensions Manager, but when I open the Test Explorer window, it does not seem to pick up any of my unit tests. Also, the Resharper 9 EAP does which is the only version of Resharper that supports VS2015 does seem yet to have the plugin for xUnit Test Runner.

How then, can I run xUnit Unit Tests in VS2015 Preview?

You can find the answer here: http://blogs.msdn.com/b/webdev/archive/2014/11/12/announcing-asp-net-features-in-visual-studio-2015-preview-and-vs2013-update-4.aspx

Visual Studio supports running and debugging for ASP.NET 5 xUnit tests through test explorer. All you need to do is add the xUnit dependencies and test commands to the test project's project.json file, as shown below (NOTE: To install the xUnit packages you will need to add https://www.myget.org/F/aspnetvnext/api/v2 as a NuGet package source):

"dependencies": {
    "Xunit.KRunner": "1.0.0-beta1"
},

"commands": {
    "test": "Xunit.KRunner"
},

---

If anyone is asking how to add https://www.myget.org/F/aspnetvnext/api/v2 as a NuGet package source... here are the steps:

1. In Visual Studio 2015 Preview go to Tools -> Options -> NuGet Package Manager -> Package Sources
2. Click the Plus (Add) button at the top (see image below)
3. Enter the Name and Source like in the image below (NOTE: be sure to click the Update button after entering the Name and Source)

Happy coding!

Answer 2

You need to add reference to these 3 nuget packages:

"xunit": "2.1.0.0-beta1-build2945",
"xunit.runner.aspnet": "2.1.0.0-beta1-build60",
"xunit.runner.visualstudio": "2.1.0.0-beta1-build1051"

Answer 3

Regarding managing / running the tests through test explorer, it is available through nuget. I had to install package xunit.runner.visualstudio version 0.99.9-build1021 in the test projects. After building the solution, the tests showed up fine and I was able to run them.

BTW, this was for a windows service but should work for ASP.NET/Web projects.

Answer 4

With visual studio 2015 RC I could not get tests to work with the following:

"xunit": "2.1.0-beta2-*",
"xunit.runner.dnx": "2.1.0-beta2-*"

But tests started showing up in the Test Explorer after changing the casing of the first letter "x" to "X"

"Xunit": "2.1.0-beta2-*",
"Xunit.runner.dnx": "2.1.0-beta2-*"

When I change it back to lower case it fails. I have not yet found a way to get these tests to show up in the latest version of Resharper at this time.

Here is the post I followed to get this far and everything worked except for the casing for some reason:

I know this will be out of date soon, but hopefully it helps someone in the mean time :)
