TRAINING PROJECT
Java testing & TDD feature delivery (Parkit)
Bug fixes, TDD unit tests and JUnit integration tests for the Park'it application at Move'it.
Context
Move'it is developing Park'it, an automated parking payment system. Previous developer Tek left several bugs and unimplemented features. Mission: fix the code, add 2 features using TDD, and reach >70% test coverage with JaCoCo and Surefire.
TDD Development Steps
- 1Bug fixFixed incorrect duration calculation for stays > 24h (producing negative values)
- 2Feature: 30-min freeTDD: tests written first, then implementation — price = 0 for stays < 30 minutes
- 3Feature: 5% recurring discountTDD: 5% discount for recurring users — license plate lookup to determine eligibility
- 4ParkingService unit testsMockito mocks to test without database — >90% coverage on ParkingService
- 5Integration testsTests against real database (ParkingDatabaseIT) — global coverage >70%
Stack & Tools
- Java + Maven for build and test execution
- JUnit 5 for unit tests
- Mockito for mocking (TicketDAO, ParkingSpotDAO, InputReaderUtil)
- JaCoCo for code coverage report
- Surefire for test execution report
