Seminar task
1. Run the tests with Coverage
- Analyze which parts of DAO classes are not covered with tests.
- Create a proposal on how to implement tests to increase line/statement coverage of these
classes (you don’t need to implement them).
2. Implement these methods using TDD (write a test, then production code)
- DepartmentDao.finaAll()
- DepartmentDao.delete(...)
3. Uncomment line marked as TASK #3 in DepartmentDao and run the tests
- This will uncover bug which is somewhere in DAO classes. Find and fix the bug.
- What are the reasons why this bug happened?
- What could be done to avoid this kind of bugs?
4. How many SQL statements is sent to DB by method EmployeeDAO.findAll()?
5. Find and resolve duplicates introduced by adding Department entity
