prohuddle-utPLSQL v3 - Ultimate unit testing framework for Oracle
2 likes2,610 views
Utplsql v3 is a free and open-source unit testing framework for Oracle databases designed for ease of use, tested on various versions of Oracle DB, and suitable for CI/CD integration. It provides features such as modular test organization, annotations for test definitions, and various matchers for expectations. The framework emphasizes best practices in unit testing, enabling developers to write effective tests that facilitate maintainable and iteratively delivered software.
![Summary
Annotation syntax:
--%name( parameter[s] )
Example:
--%suite(description)
--%test(description)
Expectation examples:
ut.expect( 1 ).to_( equal( 1 ) );
ut.expect( ‘Chuck’ ).to_equal( ‘Chuck’ );
Running tests:
exec ut.run();](https://image.slidesharecdn.com/utplsqlv3-ultimateunittestingframeworkfororacle-prohuddle-180320195958/85/prohuddle-utPLSQL-v3-Ultimate-unit-testing-framework-for-Oracle-14-320.jpg)

- 6. Why utPLSQL v3 ? ● free ● open source ● pure PL/SQL ● Tested on 11gR2 - 12cR2 ● IDE independent ● database independent ● CI/CD oriented ● modular and extendable
- 7. Properties of Unit Tests ● Fast ● Isolated ● Repeatable ● Self-verifying ● Thorough & Timely https://github.com/.../F.I.R.S.T-Principles-of-Unit-Testing https://pragprog.com/.../2012-01/unit-tests-are-first
- 8. The Unit Test also needs to be ● Simple ● Automated ● Testing one behavior ● Living documentation ● Developer’s responsibility
- 9. Delivering software that is: ● Safe to change ● Maintainable ● Can be tested and delivered iteratively Why should I care ?
- 10. What to test in database ? ● Behavior ○ Logic ○ in / out structure ○ State (?) ● Avoid ○ under-testing ○ over-testing ○ meaningless tests ○ flaky tests ○ aiming for metrics (coverage/test count)
- 11. 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 With TDD you get: ● Fast feedback loop ● Visible progress ● Code is tested before it exists ● Accomplishment with every new test
- 12. Test Driven Development with utPLSQL v3 ● suite structure ● annotations ● expectation syntax ● running tests ● failure and error messages
