Unit Tests?
Manual testing is cumbersome
Automated testing is fast
Unit tests for the TYPO3 Core
Unit Tests 406 (144) tests/s
Functional Tests 8.13 (1.97) tests/s
Acceptance Tests .009 (.003) tests/s
Verify that your code does what you expect
Make sure that your changes won‘t break anything
Keep others from breaking your code
Don’t break anything even in complex projects
Create a safety net for refactoring or for TYPO3, PHP
or Symfony updates
Improve the structure of your code
Find the location of bugs
Green feels good!
Let’s get some terms straight
The two programming modes clean hacky
Testsuite Testcase Test Assertion Test Test Testcase
The life cycle of a test new FooTest(); setUp(); /**
@test */ lifeIsGood(); tearDown();
4 test phases set up setUp() code in the test
method exercise method call verify assert…() tear down tearDown()
Code test-first write test write code refactor
Effects of TDD higher code coverage minimale code think
before you code tests now test what the code should do (instead of what it does) focused coding cleaner code structure
Test levels http:// fi lipdefar.com/2015/06/tested-be-thy-name.html
Unit tests are small and fast
Integration tests test how components work together in TYPO3:
„functional tests“
Acceptance tests Codeception Cypress
Test types
Blackbox tests test the public API
Whitebox tests inner workings test the
Anti- zombie tests-
Regression tests
Smoke tests

Naming Tests
Use meaningful test names classCanBeInstantiated setTitleSetsTitle setSizeWithZeroThrowsException hasTitleForEmptyTitleReturnsFalse Name the
behavior. Name the preconditions. Name the method. Don’t use “works” or “works correctly”. measureFrubbleWorksCorrectly
