Rider 2020.2 mstest v2 not requiring VS

Hello Pontus,

I must say that MSTest unit testing should just work in Rider 2020.2 without any additional steps. Just create a new .NET Core Unit Test Project with type MSTest via File -> New, build it and run the tests in Unit Tests tool window (View -> Tool Windows -> Unit Tests).

If you don't see any tests in the Unit Tests tool window after you build your solution, please provide the following information for further investigation:

1. OS version, for example, Windows 10 or Mac OS X 10.8
2. JetBrains Rider version: Help -> About
3. MSBuild version and type that Rider is using: Settings -> Build, Execution, Deployment -> Toolset and Build -> Use MSBuild version
4. .NET Core version
5. Also, a sample solution where the issue reproduces would be very much appreciated

Thanks in advance!

Hi! 

I did not get it to work with the .net core unit test project, sorry.

5. https://github.com/PontusAfa/RiderMSTest The sample project just contains a small project with a function, a test project, and a console app to execute the function to see that the project actually compiles and runs. No problem on my side except, of course, no tests can be run. 

Thank you for your help.

Hi Pontus,

Thanks for the information! Unfortunately, I didn't manage to reproduce your problem. Everything works fine for me. Could you please reproduce it on your machine, collect Rider logs via Help -> Collect Logs and attach the archive to a new Support request? A screenshot of an error message would also be appreciated. 

Thank you!

For anyone who has a similar problem. We've found out that MSTest support was disabled in the user's settings. Previously, Rider had a checkbox for it, but in v2020.2 it is hidden in internal mode.

Here are the steps to enable MSTest support:

1. Turn on internal mode as described here: https://rider-support.jetbrains.com/hc/en-us/articles/207327910-How-to-run-JetBrains-Rider-in-Internal-Mode
2. Go to File | Settings | Build, Execution, Deployment | Unit Testing | MSTest -> and turn on Enable MSTest support

In Rider 2021.3.2 Enable MSTest support was enabled by default. Still not working.

Jaanus Udam, could you please clarify what exactly not working? Can you add an error message if any, a screenshot? Thank you in advance!
