ERROR running force:apex:test:run: Specify a test class or test methods when running tests synchronously

[gsbasso]

Summary

Unable to run all tests synchronously.

This seems to have been introduced with release sfdx-cli/7.97.0 win32-x64 node-v15.14.0 (literally it was working on our Jenkins server in the morning and then suddenly began to fail in the afternoon, so I can only assume that the CLI version was automatically updated in between).

In the past we have had issues where tests would fail when run asynchronously so we added the -y option to our Jenkins script. Plus it has been our understanding that tests are run synchronously in production.

Steps To Reproduce:

1. Upgrade to CLI release: sfdx-cli/7.97.0 win32-x64 node-v15.14.0
2. Run the sfdx command: force:apex:test:run -u <alias> -r junit -c -y -w 90

Expected result

Tests are run

Actual result

ERROR running force:apex:test:run: Specify a test class or test methods when running tests synchronously
