Allow running only the tests that are part of an Unlocked Package and no other dependencies

[jefersonchaves]

Summary

Is there a way to request only the tests inside of an Unlocked Package to run?

I have an Unlocked Package that has Unlocked Package dependencies. I want to run the test classes part of the package and nothing else.

This is a big pain point in Unlocked Package development.

Current behaviour as of 4-Nov-204

By running sf apex run test --test-level RunLocalTests it runs all the non-namespaced tests, including dependency tests.

Alternatives

1. Bash scripting (e.g grep, awk, sed, NodeJs) to find all the test classes in a given folder and use to build sf apex run test --test-level RunSpecifiedTests --tests TestOne --tests TesTwo.
2. Manually update test suites. Not scalable.

I'm considering add a new value for --test-level which then may query all classes via tooling api and then pipe to RunSpecifiedTests behind the scenes.

The Tooling API query I could think of today for Unlocked Packages without Namespace prefix is: SELECT Name FROM ApexClass WHERE NamespacePrefix = null AND Id NOT IN (SELECT SubjectId FROM Package2Member).
