- 2. The Unit Test ● Simple ● Repeatable ● Automated ● Isolated from other tests ● Tests one behavior ● Living documentation ● Developer’s responsibility
- 3. ● Professional product delivery ● Meets requirement ● Delivered on time ● Easy to build ● Maintainable ● Safe to change Why should I care?
- 4. What to test in database? ● Logic ● Structure ● State
- 5. Why utPLSQL v3? ● open-source ● free ● complete ● unit tested ● IDE independent ● transportable ● pure PL/SQL ● CI/CD oriented ● extendable
- 6. Getting started unit testing as part of software delivery lifecycle
- 7. Test Driven Development ● write a test ● make it fail ● keep it simple ● tests are examples ● tests become documentation ● get to green fast ● take baby steps ● stuck? undo and start over ● write only enough code to pass the test ● remove duplication (in code and tests) ● rename and clean up ● run tests and stay green ● change implementation, not behavior ● improve structure in small steps RED GREEN REFACTOR
- 8. Run all tests after every single change
