Add UI tests for attaching profilers to running processes#27
Conversation
- Introduce a new test file `attachProfiler.test.ts` to validate the functionality of attaching profilers (py-spy and memray) to running processes. - Implement tests to handle both valid and initially invalid PIDs, ensuring correct command generation and terminal output. - Utilize the VS Code Extension Tester framework for UI interactions and assertions, enhancing test coverage for profiling features.

Pull Request Overview
This PR adds comprehensive UI test coverage for attaching profilers (py-spy and memray) to running processes. The tests validate the command prompt interaction flow and verify that the correct profiling commands are executed in the terminal.
- Adds end-to-end UI tests for py-spy and memray profiler attachment functionality
- Tests both valid PID scenarios and error recovery with invalid PIDs
- Validates command execution and terminal output verification

The hardcoded PID '999999' is a magic number that may not represent a valid process ID in all test environments. Consider using a more descriptive constant name like MOCK_PID or TEST_PID to clarify this is a test fixture value.

This line appears redundant since line 48 already sets the command text. The selectQuickPick call with the same text may be unnecessary or could indicate a copy-paste error from another test pattern.

attachProfiler.test.tsto validate the functionality of attaching profilers (py-spy and memray) to running processes.Note
Add UI tests that verify attaching py-spy and memray to a running PID (including invalid PID retry) via VS Code commands and terminal output.
