+# Unit Test Fixes
+
+## Problem
+The Angular unit tests were failing with errors like:
+- `NG0304: 'mat-tab' is not a known element`
+- `NG0302: The pipe 'translate' could not be found`
+- `NG0304: 'mtx-grid' is not a known element`
+- `NG0304: 'mat-form-field' is not a known element`
+
+These errors occurred because Angular's test compiler was trying to compile the component templates and couldn't find the declarations for various directives and pipes used in the templates (like Material components, translate pipe, mtx-grid, etc.).
+
+## Solution
+Added `NO_ERRORS_SCHEMA` to all component test specs to ignore unknown elements and attributes, AND imported `TranslateModule` to provide the `translate` pipe. 
+
+**Important Note:** `NO_ERRORS_SCHEMA` only ignores unknown elements and attributes - it does NOT ignore missing pipes. Since all component templates use the `translate` pipe, we must import `TranslateModule.forRoot()` in the test configuration.
+
+This combined approach is appropriate for unit tests because:
+1. **Focus on Logic** - Unit tests should test component logic, not template rendering
+2. **Minimal Changes** - Only requires adding imports and one line to config
+3. **Performance** - Tests run faster without compiling full module trees for Material components
+4. **Handles Pipes** - TranslateModule provides the translate pipe that NO_ERRORS_SCHEMA cannot ignore
+5. **Maintenance** - Less brittle when templates change
+
+## Files Modified
+
+1. **time-plannings-table.component.spec.ts**
+   - Added `NO_ERRORS_SCHEMA` import
+   - Added `TranslateModule` import
+   - Added `schemas: [NO_ERRORS_SCHEMA]` to TestBed configuration
+   - Added `TranslateModule.forRoot()` to imports array
+
+2. **time-plannings-container.component.spec.ts**
+   - Added `NO_ERRORS_SCHEMA` import
+   - Added `TranslateModule` import
+   - Added `schemas: [NO_ERRORS_SCHEMA]` to TestBed configuration
+   - Added `TranslateModule.forRoot()` to imports array
+
+3. **assigned-site-dialog.component.spec.ts**
+   - Added `NO_ERRORS_SCHEMA` import
+   - Added `TranslateModule` import
+   - Added `schemas: [NO_ERRORS_SCHEMA]` to TestBed configuration
+   - Added `TranslateModule.forRoot()` to imports array
+
+4. **workday-entity-dialog.component.spec.ts**
+   - Added `NO_ERRORS_SCHEMA` import
+   - Added `TranslateModule` import
+   - Added `schemas: [NO_ERRORS_SCHEMA]` to TestBed configuration
+   - Added `TranslateModule.forRoot()` to imports array
+
+5. **download-excel-dialog.component.spec.ts**
+   - Added `NO_ERRORS_SCHEMA` import
+   - Added `TranslateModule` import
+   - Added `schemas: [NO_ERRORS_SCHEMA]` to TestBed configuration
+   - Added `TranslateModule.forRoot()` to imports array
+
+## Change Summary
+- **5 files changed**
+- **15 insertions(+)**, **5 deletions(-)**
+- All changes are minimal and focused
+
+## Testing
+To run the tests, use the command specified in the issue:
+```bash
+npm run test:unit -- --testPathPatterns=time-planning-pn --coverage --collectCoverageFrom='src/app/plugins/modules/time-planning-pn/**/*.ts' --coveragePathIgnorePatterns='\.spec\.ts'
+```
+
+## Why This Approach Works
+
+### NO_ERRORS_SCHEMA handles:
+- Unknown elements (mat-tab, mat-form-field, mat-button, etc.)
+- Unknown attributes (matTooltip, matStartDate, etc.)
+- Unknown components (mtx-grid, mtx-select, etc.)
+
+### TranslateModule handles:
+- The `translate` pipe used throughout templates
+- Provides actual pipe implementation for template compilation
+
+### Alternative Approach (Not Used)
+The alternative would have been to import all the required modules:
+- All Material modules (MatTabModule, MatFormFieldModule, MatInputModule, etc.)
+- MtxGridModule
+- Other dependencies
+
+This approach was rejected because:
+- Much more invasive changes (20+ module imports per test)
+- Harder to maintain
+- Slower test execution
+- Not appropriate for unit tests (better suited for integration tests)
+- Would require adding many more imports and potentially mocking more services
+
+## Verification
+All tests should now compile and run successfully without template-related errors. The component logic tests remain unchanged and will verify the business logic of each component.
