coverlet.exe / application coverage: exception "application does not have a console or when console input has been redirected"

[pkrukp]

Hello,

I tried to collect application coverage (coverlet.exe) from a simple .net core 3.1 console application which reads from standard input (Console.ReadKey()). I got an exception. It looks like coverlet.exe does not provide/pass/redirect standard input to the executed program.

The error I got was:

$ coverlet.exe bin/Debug/netcoreapp3.1/console2.exe --target bin/Debug/netcoreapp3.1/console2.exe --include-test-assembly
Hello World!
Press any key to continue...
Unhandled exception. System.InvalidOperationException: Cannot read keys when either application does not have a console or when console input has been redirected. Try Console.Read.

Attaching the console2 project for your convenience: console2.zip

I'm using coverlet.exe 1.7.0.0

Thanks for reporting this

I'm not sure if this is something we want to support. My expectation for a console test runner is that it runs to completion in a non-interactive way. I don't think I'll classify it as a bug

I thought it simply collects coverage from executed application...

Since next version we allow e2e test coverage, so maybe also a console app that accepts input could be a use case, what do you think @tonerdo?

[pkrukp]

Do you know when that next version will be available?

I prefer to spend more time optimizing for the common case which is usually non-interactive runs in CI servers. Even when using the integration test feature

Moved to enhancement

@pkruk2 the idea is to release within end of the year.
