Ability to export search results to CSV, JSON, or plain text

[Copilot]

Pull request overview

This pull request adds a new feature to export search results in VS Code to various formats (JSON, CSV, Plain Text). The feature allows users to save search results for analysis, sharing, or archival purposes.

Key Changes

• New export action registered in the search context menu and command palette that serializes search results to JSON, CSV, or Plain Text formats
• Progress tracking for large exports (>500 matches or >20 files) with cancellation support
• Preference persistence to remember last used format and export path across sessions

This test is redundant and doesn't test any actual functionality. It simply asserts that a string literal equals itself ("search.action.export" === "search.action.export"). Consider removing this test or making it verify that the actual constant from the codebase matches the expected value by importing and checking Constants.SearchCommandIds.ExportSearchResultsActionId.

The extension manipulation logic has a bug. When currentExt !== expectedExtension and currentExt is truthy, the condition on line 507 is redundant because it's checking the same condition that was already checked on line 505. This means the else if (!currentExt) block on line 510 will never be reached. Consider simplifying to:

if (currentExt !== expectedExtension) {
  if (currentExt) {
    // Remove wrong extension
    const pathWithoutExt = fileUri.path.slice(0, -currentExt.length);
    fileUri = fileUri.with({ path: pathWithoutExt + expectedExtension });
  } else {
    // No extension, add the correct one
    fileUri = fileUri.with({ path: fileUri.path + expectedExtension });
  }
}

Use single quotes for string literals to follow the project's coding guidelines. The codebase consistently uses single quotes for strings.

Use single quotes for string literals to follow the project's coding guidelines. Throughout this entire file, double quotes are used but the codebase consistently uses single quotes for non-externalized strings.

This file appears to be a test plan document rather than an executable test file. Browser integration tests in VS Code should follow the established patterns in test/integration/ or test/smoke/ directories. Consider removing this file or moving it to a documentation location, or implementing actual browser tests using the VS Code automation API.

[Copilot]

This test file is using .js file extension in the import path (./src/application.js), but VS Code tests typically use .ts extensions and rely on the build system to resolve them. Additionally, this test appears to be incomplete as it only verifies that commands execute without checking the actual export functionality. Consider either completing this test or removing it in favor of unit tests that can fully validate the export behavior.
