Test Coverage Assessment for PR #45

I've reviewed the changes and test coverage for the pagination cursor feature.

Changes Summary

This PR adds pagination cursor support to cfl space list:

1. New --cursor flag for specifying a pagination cursor
2. extractCursor() helper function to parse cursor from next page links
3. Updated output to show the next page command when more results exist

Test Coverage Analysis

Well Covered:

• TestRunList_WithCursor - Verifies the cursor parameter is correctly passed to the API endpoint
• TestRunList_DisplaysNextCursor - Verifies the next page cursor is extracted from the API response and displayed to stderr with the proper command format
• TestExtractCursor - Comprehensive table-driven tests covering:
  • Valid cursor with other query params
  • Empty link (returns empty string)
  • Missing cursor param (returns empty string)
  • Full URL with cursor

Coverage Gaps Noted (acceptable):

1. No API-layer test for cursor in spaces.go: The api/spaces_test.go file doesn't have a specific test for the Cursor option. However, this is a minor gap because:

   • The TestRunList_WithCursor test verifies end-to-end that the cursor reaches the API
   • The api/pages_test.go has TestClient_ListPages_WithCursor which tests the same pattern
   • The implementation in spaces.go is straightforward (if opts.Cursor != "" { params.Set("cursor", opts.Cursor) })

2. Malformed URL edge case: extractCursor() handles url.Parse errors by returning empty string, but there's no explicit test for this. This is acceptable since:

   • The function is defensive (returns empty string on error)
   • Confluence's API should return well-formed URLs
   • The fallback behavior (showing the old "use --limit" message) is tested implicitly

Verdict

Test coverage is adequate. The critical paths are tested:

• Cursor is correctly passed to the API
• Cursor is correctly extracted from response links
• User sees helpful next-page command in output

The implementation follows the same pattern as the existing pages pagination, and the tests are consistent with the testing patterns used elsewhere in the codebase.
