Phase 03 Plan 03: BackendSelectionStep Summary

BackendSelectionStep implemented with TDD: remote name zod validation (onSubmit mode) and popularity-sorted backend card grid that validates name before dispatching three store actions on card click.

Tasks Completed

Task	Name	Commit	Files
RED	Add failing tests for BackendSelectionStep	cf06d72	src/components/wizard/BackendSelectionStep.test.tsx
GREEN	Implement BackendSelectionStep	b47f607	src/components/wizard/BackendSelectionStep.tsx, BackendSelectionStep.test.tsx

What Was Built

BackendSelectionStep — Step 0 of the wizard. Renders a remote name text field (top) with zod-powered react-hook-form validation, followed by three backend selection cards in popularity order (Azure Blob Storage, Amazon S3, S3-Compatible).

Clicking a card triggers handleSubmit internally — the form validates the remote name before dispatching actions. If the name is invalid, an inline error appears and navigation does not proceed. On valid submit, the component dispatches:

1. SET_REMOTE_NAME — stores the validated name
2. SET_BACKEND_TYPE — stores the selected backend
3. SET_REMOTE_PARAMS({}) — clears any stale backend-specific params
4. SET_STEP(1) — advances to step 1

The component never dispatches RESET — deployment options (includeInstall, configPath, scriptTargets) are preserved across back-navigation.

TDD Execution

• RED commit: cf06d72 — 10 test stubs replaced with real assertions, failing because component did not exist
• GREEN commit: b47f607 — Component implemented, all 10 tests pass

Verification

Test Files  1 passed (1)
Tests      10 passed (10)

All WIZD-01 and WIZD-04 cases GREEN. Full suite: 71 passing, 16 RED (expected expect.fail stubs from Plans 03-04 and 03-05).

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Added waitFor to async validation tests

• Found during: GREEN phase test run
• Issue: handleSubmit is async — React state updates from zod validation don't flush synchronously. Tests using fireEvent.click without waitFor found no alert in DOM.
• Fix: Imported waitFor from @testing-library/react; wrapped post-click assertions in await waitFor(...) for the three tests that assert on validation error presence/absence.
• Files modified: src/components/wizard/BackendSelectionStep.test.tsx
• Commit: b47f607

Self-Check

• src/components/wizard/BackendSelectionStep.tsx exists
• src/components/wizard/BackendSelectionStep.test.tsx updated with real tests
• Commit cf06d72 exists (RED tests)
• Commit b47f607 exists (GREEN implementation)
• All 10 BackendSelectionStep tests GREEN
• No regressions in previously passing tests (71 passing)
