Summary

Enable the assign button for placement tests using the generator engine, even when their question pool is empty. Generator-based tests can dynamically create questions, so an empty question list should not block assignment.

Changes

  • TestListPage.tsx: Updated the assign button's disabled state logic in two locations to allow assignment when a test is a generator test, regardless of whether questions array is empty
    • Changed condition from disabled={test.questions.length === 0} to disabled={test.questions.length === 0 && !isGeneratorTest(test)}
    • Applied to both the main test list and expanded/detail view
  • Imports: Added isGeneratorTest utility import from src/utils/placementGenerator
  • TestListPage.test.tsx: Added test case verifying that the assign button is enabled for a generator placement test with an empty question pool

Implementation Details

The fix leverages the existing isGeneratorTest() utility to detect tests configured with mode: 'placement' and placementEngine: 'generator'. These tests can generate questions dynamically based on their generatorConfig settings, so they should be assignable even without pre-populated questions.

https://claude.ai/code/session_01U1T6mPsw1hee26nv1nTsvQ

Generator-engine placement tests (mode 'placement', placementEngine
'generator') intentionally carry an empty questions array — every
question is pulled live from the bank at runtime by the
next-placement-question edge function, with only a configured starter.
The assign button in TestListPage used `test.questions.length === 0` as
its "empty test, nothing to assign" guard, which permanently disabled
assignment for these tests.

Exclude generator tests from that guard via the existing isGeneratorTest
helper, in both the table and grid views, and add a regression test.

📝 Walkthrough

Walkthrough

TestListPage keeps Assign enabled for generator-based tests with empty question arrays in list and card views. A test verifies this behavior and preserves disabled behavior for other question-less tests.

Changes

Generator assignment availability

Layer / File(s) Summary
Update assignment rule and validation
src/pages/TestListPage.tsx, src/pages/__tests__/TestListPage.test.tsx
Both Assign buttons allow generator-based tests with no explicit questions. A test verifies the enabled state in card and list views.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to a881b

Generator-based placement tests with empty question pools can now be assigned in both views. Runtime behavior is covered, with only minor test-comment cleanup remaining before merge.

The generator-assign fix changed the disabled condition in both the
card (grid) and table (list) views of TestListPage, but the regression
test only rendered the default card view, leaving the list-view branch
uncovered. Switch to the list view and re-assert so both changed
conditions are exercised.

Comment thread src/pages/__tests__/TestListPage.test.tsx Outdated
Per the repo comment convention (no comments describing what the code
does), remove the two view-labelling comments from the generator-assign
regression test; the actions and assertions already make the covered
views clear. No behavior change.
