How can i specify the reflection engine mode for VS Test Explorer?

[AdmiralSnyder]

I'm trying to convert a bUnit test project from xUnit to TUnit.

since bUnit allows for expressing unit tests in razor components which are then source generated at compile time to .cs files, TUnit cannot see those, and the tests don't show up in VS solution explorer.
i'd like to configure the test project to emit reflection-friendly info so the tests do show up - how would i do that?

The tests do show up when i do dotnet test -- --reflection - so how do i do it inside VS?

thanks a lot :-)

for now, i'm falling back to specifying the environment variable
TUNIT_EXECUTION_MODE as reflection
but that means that all my unit tests run as reflection. please also add a check regarding one of the assembly attributes

...

what do you think about looking at the assembly attribute TUnitReflectionScanner too, in TUnit.Engine.Framework.TUnitServiceProvider.GetUseSourceGeneration?
this would enable me to just put that attribute into that specific bUnit assembly and be done with it...

oh, and also, this needs to be documented. i'll PR this quickly.

I've enabled reflection mode for our bUnit test project by setting this environment variable through the .runsettings file. This works with the VS Test Explorer.

Here’s the approach I took:

• I created a dedicated test project just for the bUnit tests.
• I added a .runsettings file to set this environment variable.
• I then referenced this .runsettings file in the .csproj.

.runsettings

<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
  <RunConfiguration>
    <EnvironmentVariables>
      <TUNIT_EXECUTION_MODE>reflection</TUNIT_EXECUTION_MODE>
    </EnvironmentVariables>
  </RunConfiguration>
</RunSettings>

Project.Tests.csproj

<PropertyGroup>
  <RunSettingsFilePath>$(MSBuildProjectDirectory)\.runsettings</RunSettingsFilePath>
</PropertyGroup>

Thanks @johanbenschop .

@AdmiralSnyder does that answer things for you?

Yeah, I am doing it this way, but I don't like the additional effort, it would be so much nicer if less stuff was needed. See my other comments...
