1. Unit testing with TYPO3 Oliver Klee, 2015-10-26 @oliklee typo3-coding@oliverklee.de
2. Unit tests?
3. Manual testing is cumbersome
4. Automated testing is fast
5. Unit tests for the
 Realty Manager extension
6. more than
 1600 tests
7. in less than 60 seconds
8. Verify that your code does what you expect
9. Make sure that your changes won‘t break anything
10. Keep
    other coders
    from breaking your code
11. Don‘t break anything
    even in complex projects
12. Create a safety net
    for refactoring
13. Improve the structure of the code
14. Green feelsgood!
16. Know your tools
17. The phpunit extension has it all phpunit (TYPO3 extension) PHPUnit (Composer package) Testrunner (back-end- module) Testrunner
 (CLI module) Testing framework for FE & DB
18. Let‘s get some terms straight
19. Test suite Test case Test Two tests meet in a bar ... Assertion Test Test Test case
20. The life cycle of a unit test new FooTest(); setUp(); /** @test */ lifeIsGood(); tearDown();
21. 4 test phases Setup Exercise Verify Teardown setUp() in the test method call assert… tearDown() https://robots.thoughtbot.com/four-phase-test
22. Code test-first write
 test write code refactor
23. kata Code
24. Testing levels http://dabrorius.github.io/2015/06/tested-be-thy-name.html
25. Unit tests are
    small and fast
26. Integration tests check the interaction
    of components
27. System tests test
    the complete system
28. Test types
29. Blackbox tests what is visible to the outside test
30. Whitebox tests inner workings test the
31. Functional
 tests
32. Acceptance tests Selenium
33. Regression tests
34. Smoke tests
35. Smoke tests
36. Use meaningful
    unit test names classCanBeInstantiated setTitleSetsTitle setSizeWithZeroThrowsException hasTitleForEmptyTitleReturnsFalse Name the behavior. Name the preconditions. Mention the method. Dont‘t use "works" or "correctly". measureFrubbleWorksCorrectly
37. The testing framework
    is created quickly /** * @var Tx_Phpunit_Framework */ protected $testingFramework = NULL; protected function setUp() { $this->testingFramework = new Tx_Phpunit_Framework('tx_news2'); } protected function tearDown() { $this->testingFramework->cleanUp(); } CREATE TABLE tx_news2_domain_model_news ( … is_dummy_record tinyint(1) unsigned DEFAULT '0' NOT NULL, … discard the FE,
 delete DB records,
 delete files
38. $recordUid = $tf->createRecord($tableName, array $recordData = array()); The testing framework
    can fake almost everything $tf->changeRecord($tableName, $uid, array $recordData); $tf->deleteRecord($tableName, $uid); $tf->createRelation($tableName, $uidLocal, $uidForeign, $sorting = 0); $tf->createRelationAndUpdateCounter($tableName, $uidLocal, $uidForeign, $columnName); $tf->removeRelation($tableName, $uidLocal, $uidForeign); $numberOfRecords = $tf->countRecords($tableName, $whereClause = ''); $success = $tf->existsRecord($tableName, $whereClause = ''); $success = $tf->existsRecordWithUid($tableName, $uid); $success = $tf->existsExactlyOneRecord($tableName, $whereClause = '');
39. $groupUid = $tf->createFrontEndUserGroup(array $recordData = array()); $userUid = $tf->createFrontEndUser($groups = '', array $recordData = array()); $userUid = $tf->createAndLoginFrontEndUser($groups = '', array $recordData = array()); $pageUid = $tf->createFrontEndPage($parentId = 0, array $recordData = array()); $pageUid = $tf->createSystemFolder($parentId = 0, array $recordData = array()); $elementUid = $tf->createContentElement($pageId = 0, array $recordData = array()); $tf->createTemplate($pageId, array $recordData = array()); $pageUid = $tf->createFakeFrontEnd($pageUid = 0); $tf->discardFakeFrontEnd(); $tf->loginFrontEndUser($userId); $tf->logoutFrontEndUser(); $isLoggedIn = $tf->isLoggedIn(); The testing framework
    can fake almost everything
40. $recordUid = $tf->createBackEndUser(array $recordData = array()); $recordUid = $tf->createBackEndUserGroup(array $recordData = array()); The testing framework
    can fake almost everything
41. $path = $tf->createDummyFile($fileName = 'test.txt', $content = ''); $path = $tf->createDummyZipArchive($fileName = 'test.zip', array $filesToAdd = array()); $tf->deleteDummyFile($fileName); $tf->deleteDummyFolder($folderName); $path = $tf->createDummyFolder($folderName); The testing framework
    can fake almost everything
