2. ● Definitions

Agenda

3. SUT = Subject Under Test
● Unit testing
○ Procedural programming - procedure
○ Functional programming - function
○ OOP - object
● Non-unit testing - REST service, UI app, cli app, DB, etc.
● Examples
○ Unit testing
○ Non-unit testing

4. CI = Continuous Integration
● “is the practice of automating the integration of code changes from multiple
contributors into a single software project”
● “CI process is comprised of automatic tools that assert the new code’s
correctness before integration.”
● Tools - version control system, automated code quality tests, syntax style
review tools, and more.

8. Test Suite
● Contains test cases
● Contains test suites
(composite)
● Demo

9. Test Suite - test case organization
● Per feature - user login
● Per fixture - test cases need a shopping basket with 2
items inside.

13. Project Smells

14. Behavior Smells
● API/UI sensitivity
● Context/Data sensitivity - Fixture’s modified.
● Behavior sensitivity - SUT’s modified.

15. Code Smells
● Obscure tests
● Conditional test logic
● Hard-coded test data literals
● Hard-to-test code
