Copy-and-Paste: 7. Comprehensive Testing and Validation

⚠️ Important: Use the /feature/copy-and-paste branch as the base branch for this feature.

Covers Development Plan Point: 9

Description:
This task focuses on thorough testing of the entire copy-and-paste feature across various scenarios to ensure reliability, correctness, and a smooth user experience. While individual components will have unit tests, this task emphasizes integration and end-to-end testing.

Requirements:

1. Diverse Dataset Testing:
   • Test with collections of varying sizes (small, medium).
   • Test with documents of different structures and data types.
   • Test with empty collections.
2. Scenario Testing:
   • Cross-cluster/server migrations: Copying between different MongoDB instances/servers.
   • Same-cluster migrations: Copying between different databases or collections within the same server.
   • Document Conflicts:
     • Test all configured WriteConflictStrategy options (Abort, SkipAndLog, Overwrite as defined in "Copy-and-Paste: 4. Implement Conflict Resolution Options (UI and Task Update)").
   • General Write Errors (including Schema Validation Errors if applicable):
     • Test behavior with WriteConflictStrategy (Abort, SkipAndLog, and how Overwrite falls back for these errors).
   • Index Copying:
     • Verify indexes are copied correctly when IndexCopyOption.Yes is selected (enum from "Copy-and-Paste: 4. Implement Conflict Resolution Options (UI and Task Update)").
     • Verify indexes are not copied when the option is deselected.
3. Error Handling and Abort Validation:
   • Induce errors (e.g., network interruption briefly, invalid credentials for target during setup) to test error reporting and task failure states.
   • Test the abort functionality at various stages of the copy process. Verify that data copied up to the abort point is preserved on the target.
4. Performance Validation (for smaller datasets):
   • Ensure the feature performs adequately for its intended use case (smaller datasets).
   • Monitor for any excessive memory usage or UI freezes.
5. Edge Case Handling:
   • Test with unusual collection or database names (e.g., containing special characters, if supported by the DB).
   • Test rapidly starting multiple copy tasks.
   • Test UI interactions like canceling dialogs at various points.

Acceptance Criteria:

• The copy-and-paste feature functions correctly across a wide range of defined test scenarios and datasets.
• Conflict resolution, error handling, progress reporting, and abort mechanisms work as expected.
• The feature is stable and does not introduce regressions or negatively impact VS Code performance significantly for its intended scope.
• A test plan document or checklist is created and executed, with results documented.
