Unable to test dotnet project

[Abir Stolov]

I'm trying to run dotnet test on a solution and unable to.

pipeline:

image: mcr.microsoft.com/dotnet/sdk:6.0

pipelines:

  default:

  - step:

      name: Build

      caches:

        - dotnetcore

      script:

        - dotnet restore

        - dotnet build --no-restore --configuration Release

        - dotnet test --no-build --no-restore -v d

If I remove the last line, `dotnet test`... than is it successful

The error shown is:

Test run for /opt/atlassian/pipelines/agent/build/thresholds-module.tests/bin/Debug/net6.0/thresholds-module.tests.dll (.NETCoreApp,Version=v6.0)

The argument /opt/atlassian/pipelines/agent/build/thresholds-module.tests/bin/Debug/net6.0/thresholds-module.tests.dll is invalid. Please use the /help option to check the list of valid arguments.

I found this answer on my search for the same error, so I'll answer it for the next ones coming here.

Look at the last 2 commands in your script:

- dotnet build --no-restore --configuration Release
- dotnet test --no-build --no-restore -v d

You are building in Release configuration but are testing in Debug configuration.

So the dotnet test command doesn't find any assemblies for running tests due to the --no-build switch.

In this case I think it would have been much more helpful for you (and me) if the error message had been a "file not found" instead of the less specific "argument is invalid".
