   • AUse a single CodeBuild project but manually specify which package to test via environment variables.
   • BRun all unit tests for all packages on every build to ensure nothing is broken.
   • CCreate separate CodeBuild projects for each package and trigger them all on every push.
   • DUse a script in the buildspec to identify the changed files and run only the corresponding package's tests.
