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
