Pull request overview
This PR adds project-aware pytest execution support to the test controller flow by wiring Python Environments “projects” into execution/debugging, and introducing shared helpers + unit tests to validate the new behavior in multi-project workspaces.
Changes:
- Add project-based test execution orchestration (
executeTestsForProjects, grouping test items by owning project, per-project execution). - Pass project context into pytest execution and debugging (env var
PROJECT_ROOT_PATH,LaunchOptions.project, project-derived Python path/session naming). - Add centralized test mocks and new/updated unit tests covering project execution and debug-session lifecycle handling.
