The diff-mode cycle in PermissionsScreen referenced DiffDisplayMode.SIDE_BY_SIDE
and DiffDisplayMode.CONTEXT, but the enum only defines UNIFIED / SPLIT / AUTO.
Pyright flagged both as reportAttributeAccessIssue and behave failed to import
the screen module, masking the entire scenario suite under a single
traceback-outside-scenario error.
Also addresses the prior re-review feedback on the same PR:
- compose() return type was Any; tighten to collections.abc.Iterator[Any] so the
generator shape is exposed to type checkers without taking a hard textual
dependency at typecheck time (Iterator[Any] is the structural type of a
Textual ComposeResult; we stay importable when textual is absent).
- The Bug #10488 TDD scenario asserting action methods now also covers
action_dismiss_screen so a future refactor cannot silently drop the escape
binding without test failure.
Verified locally on this worktree:
- typecheck gate: 0 errors, 4 unrelated warnings.
- unit_tests gate on features/tui_permissions_screen.feature: 65/65 scenarios
pass.
- lint gate: clean.
ISSUES CLOSED: #10488
Applied ruff format fix to tui_permissions_screen_steps.py and corrected the step text mismatch in execution_environment.feature where 'it should not contain' was not updated to 'the container types should not contain' when the step definition was renamed.
ISSUES CLOSED: #10488
- Renamed 'it should contain' steps to 'the container types should contain' for specificity
- Updated execution_environment.feature to use the new step names
- This fixes the AmbiguousStep error that was preventing unit tests from running
- Changed PermissionsScreen to inherit from textual.app.Screen instead of textual.widgets.Static
- Added BINDINGS class variable with keyboard bindings for a, A, r, R, j, k, d, escape
- Implemented action methods: action_allow_once, action_allow_always, action_reject_once, action_reject_always, action_nav_next, action_nav_prev, action_cycle_diff, action_dismiss_screen
- Added compose() method for Textual screen layout
- Added update() method for backward compatibility with tests
- Added TDD Behave scenarios tagged @tdd_issue @tdd_issue_10488 to verify the fix
- All 65 unit test scenarios pass
