|
|
|
These tests fail because they depend on the `ManifestMigrator` class which is not yet implemented. This is expected and by design:
|
|
|
|
#### 1. questions-skipped-on-update.test.js
|
|
|
|
- **Tests**: 8 total (2 passing, 6 failing)
|
|
- **Status**: ⏳ PARTIAL
|
|
- **Issue**: Missing ManifestMigrator for field migration
|
|
- **Passing Tests**:
|
|
- Basic update flow
|
|
- Configuration caching
|
|
|
|
#### 2. backward-compatibility.test.js
|
|
|
|
- **Tests**: 15 total (0 passing, 15 failing)
|
|
- **Status**: ⏳ PENDING
|
|
- **Issue**: Missing ManifestMigrator for v4→v5→v6 migration
|
|
- **Purpose**: Version migration scenarios
|
|
|
|
#### 3. invalid-manifest-fallback.test.js
|
|
|
|
- **Tests**: 8 total (0 passing, 8 failing)
|
|
- **Status**: ⏳ PENDING
|
|
- **Issue**: Missing ManifestMigrator and error recovery
|
|
- **Purpose**: Error handling and recovery
|
|
|
|
#### 4. install-config-loading.test.js (Partial)
|
|
|
|
- **Tests**: 6 total (6 passing, 0 failing)
|
|
