I get the same error. It's also triggered from the Test view when I press the Play button.

But I would also like to say that if I use the SFDX: Invoke Apex Tests... option from the command palette the tests are run. The command issued is different though:

sfdx force:apex:test:run --classnames <HereGoesMyClassName> --synchronous --resultformat human --loglevel error

In the classnames param the namespace is omitted.

My team is also experiencing this issue. We sometimes create non-namespaced orgs - it's only happening in that environment for us. The command is assuming the org is namespaced and adding the namespace to the class name when it is not. For our namespaced orgs, these run successfully. @shillem's workaround works for us.

(I added these details as a comment in the linked WI as well)

@robertbwatson same here. The only workaround I see now is to delete the namespace from the example dx command presented in output:

19:59:37.362 sfdx force:apex:test:run --tests <namespace>.<classname>.<testname> --resultformat human --outputdir /Users/julian.joseph/Documents/Repos/spc-integration/.sfdx/tools/testresults/apex --loglevel error ERROR running force:apex:test:run: Unable to invoke any tests. Ensure the tests are loaded into the org or valid inputs are supplied. This class name's value is invalid: ccsi01.DataLakeApiService_TEST. Provide the name of an Apex class that has test methods.

Change: sfdx force:apex:test:run --tests <namespace>.<classname>.<testname> --resultformat human --outputdir /Users/julian.joseph/Documents/Repos/spc-integration/.sfdx/tools/testresults/apex --loglevel error

to

sfdx force:apex:test:run --tests <classname>.<testname> --resultformat human --outputdir /Users/julian.joseph/Documents/Repos/spc-integration/.sfdx/tools/testresults/apex --loglevel error

and rerun in terminal

As of today, this issue is still happening. Thanks for the workarounds.

Created an org with a namespace today and I'm now facing this issue as well. It is really weird, it seems the extension is trying to add the namespace twice...

This class name's value is invalid: .. Provide the name of an Apex class that has test methods.

I'm also experiencing this issue, but not on all test methods. I can get one class to work, but I'm not seeing anything stand out as different in this class.
Update: After restarting, they are all failing again

[aaronmorris]

A workaround that looks to be working for me is:
In the settings there is a new feature that needs to be disabled

In Settings: Salesforcedx-vscode-core > Experimental: Use Apex Library
Disable - Use Apex Library for Apex CLI Commands

Closing since this was fixed in release 51.2.0 of the Salesforce Extensions for VSCode. Thanks for providing feedback.
