dotnet test does not find any tests if environment variable is set that ends with .dll or .exe

[jbe2277]

We use environment variables in UI tests to specify on our build machines where our application (executable) can be found.

dotnet test UITests/UITests.sln -e UITestExe="C:\OurApp.exe"

By defining an environment variable that ends on .exe or .dll the dotnet test does not find unit tests anymore.

Reason: In this case dotnet test searches the file specified as environment variable for unit tests.

• Related issue: dotnet test does not find any tests if environment variable is set that ends with dll #28592
  • Just an ending with dll works but .dll does not work
• PR that solved the previous issue: Fix parsing for arguments ending with dll/exe #28662

It seems the the PR #28662 did not solve this completely.

Perhaps you can work around it by setting the environment variable with a directive instead, as shown in #40484.

Yes, this works: dotnet [env:UITestExe="C:\OurApp.exe"] test UITests/UITests.sln

I did not find any information about this special syntax. Is this somewhere documented?
