| 1 | +# Unit Testing and Refactoring Summary |
| 2 | + |
| 3 | +## Overview |
| 4 | +This document summarizes the unit testing infrastructure and refactoring work done to improve testability of the Time Planning Plugin components. |
| 5 | + |
| 6 | +## Refactorings Made |
| 7 | + |
| 8 | +### 1. TimePlanningsContainerComponent |
| 9 | + |
| 10 | +#### Date Navigation Refactoring |
| 11 | +**Problem**: Date manipulation was mutating the original date objects using `setDate()` which could cause side effects. |
| 12 | + |
| 13 | +**Solution**: Extracted date manipulation into a pure helper method `addDays()` that creates new Date instances: |
| 14 | + |
| 15 | +```typescript |
| 16 | +private addDays(date: Date, days: number): Date { |
| 17 | + const result = new Date(date); |
| 18 | + result.setDate(result.getDate() + days); |
| 19 | + return result; |
| 20 | +} |
| 21 | +``` |
| 22 | + |
| 23 | +**Benefits**: |
| 24 | +- Immutability: Original dates are not modified |
| 25 | +- Testability: Pure function that's easy to test in isolation |
| 26 | +- Reusability: Can be used for any date addition logic |
| 27 | + |
| 28 | +### 2. TimePlanningsTableComponent |
| 29 | + |
| 30 | +#### Cell Class Logic Refactoring |
| 31 | +**Problem**: Complex nested ternary operator on line 151 made the code difficult to read, understand, and test: |
| 32 | +```typescript |
| 33 | +return workDayStarted ? workDayEnded ? 'green-background' : 'red-background' : plannedStarted ? 'grey-background' : message || workerComment ? 'grey-background' : 'white-background'; |
| 34 | +``` |
| 35 | + |
| 36 | +**Solution**: Extracted the complex logic into a separate helper method `getCellClassForNoPlanHours()`: |
| 37 | + |
| 38 | +```typescript |
| 39 | +private getCellClassForNoPlanHours( |
| 40 | + workDayStarted: boolean, |
| 41 | + workDayEnded: boolean, |
| 42 | + plannedStarted: any, |
| 43 | + message: any, |
| 44 | + workerComment: any |
| 45 | +): string { |
| 46 | + if (workDayStarted) { |
| 47 | + return workDayEnded ? 'green-background' : 'red-background'; |
| 48 | + } |
| 49 | + |
| 50 | + if (plannedStarted) { |
| 51 | + return 'grey-background'; |
| 52 | + } |
| 53 | + |
| 54 | + if (message || workerComment) { |
| 55 | + return 'grey-background'; |
| 56 | + } |
| 57 | + |
| 58 | + return 'white-background'; |
| 59 | +} |
| 60 | +``` |
| 61 | + |
| 62 | +**Benefits**: |
| 63 | +- Readability: Each condition is on its own line with clear logic |
| 64 | +- Testability: Can test the helper method independently |
| 65 | +- Maintainability: Easier to modify or extend the logic |
| 66 | + |
| 67 | +#### Cell Text Color Logic Refactoring |
| 68 | +**Problem**: Similar nested ternary operator issue on line 183. |
| 69 | + |
| 70 | +**Solution**: Extracted into `getCellTextColorForNoPlanHours()` helper method with clear if-else logic. |
| 71 | + |
| 72 | +**Benefits**: Same as above - improved readability, testability, and maintainability. |
| 73 | + |
| 74 | +#### Removed Duplicate Condition Check |
| 75 | +**Problem**: Line 134 had redundant condition: `if (nettoHoursOverrideActive && nettoHoursOverrideActive)` |
| 76 | + |
| 77 | +**Solution**: Simplified to: `if (nettoHoursOverrideActive)` |
| 78 | + |

| 109 | +## GitHub Actions Integration |
| 110 | + |
| 111 | +### Workflows Updated |
| 112 | +1. **dotnet-core-master.yml**: Added `angular-unit-test` job |
| 113 | +2. **dotnet-core-pr.yml**: Added `angular-unit-test` job |
| 114 | + |
| 115 | +### Test Execution |
| 116 | +The unit tests will run after the build job completes and before the e2e tests. They execute with: |
| 117 | +```bash |
| 118 | +npm run test:ci -- --include='**/time-planning-pn/**/*.spec.ts' |
| 119 | +``` |
| 120 | + |

| 150 | +## Best Practices Followed |
| 151 | + |
| 152 | +1. **Isolated Testing**: Each test is independent and doesn't rely on others |
| 153 | +2. **Mocking**: All dependencies are mocked using Jasmine spies |
| 154 | +3. **Descriptive Names**: Test names clearly describe what they're testing |
| 155 | +4. **Arrange-Act-Assert**: Tests follow the AAA pattern |
| 156 | +5. **Edge Cases**: Tests cover normal cases, edge cases, and error scenarios |
| 157 | +6. **Pure Functions**: Refactored methods are pure functions where possible |
| 158 | + |
| 159 | +## Future Improvements |
| 160 | + |
| 161 | +1. Add tests for the more complex dialog components (WorkdayEntityDialogComponent, AssignedSiteDialogComponent) |
| 162 | +2. Add integration tests that test component interactions |
| 163 | +3. Add tests for the state management if using NgRx |
| 164 | +4. Consider adding code coverage reporting to the CI pipeline |
| 165 | +5. Add visual regression testing for UI components |
| 166 | + |
| 167 | +## Running Tests Locally |
| 168 | + |
| 169 | +When the plugin is integrated into the main frontend: |
| 170 | + |
| 171 | +```bash |
| 172 | +# Install dependencies |
| 173 | +cd eform-angular-frontend/eform-client |
| 174 | +npm install |
| 175 | + |
| 176 | +# Run all tests |
| 177 | +npm test |
| 178 | + |
| 179 | +# Run tests in watch mode |
| 180 | +npm run test:watch |
| 181 | + |
| 182 | +# Run tests with coverage |
| 183 | +npm run test:coverage |
| 184 | + |
| 185 | +# Run only time-planning tests |
| 186 | +npm test -- --include='**/time-planning-pn/**/*.spec.ts' |
| 187 | +``` |
| 188 | + |
| 189 | +## Conclusion |
