Demo package



Bekendheid met testen

100% coverage en CI!

in control, goede coverage

starten goed, houden niet bij

te weinig, helaas...

... tests?



Crap in === crap out

Eindproduct



Team Profiel - De enthousiaste developer

Yeah, nieuw project!




Lekker vaartje!




Eeeh, waar ben ik?




Ooeeeeeei!

Test Driven Development?

Schrijf eerst test === denk eerst

Snelste weg naar slagende test

Refactor later



“Cease dependence on mass inspection to achieve quality.

Improve the process and build quality into the product in

the first place.”

Test Driven Development Quotes



PHP Code Testen

Flow testing framework gebruikt PHPUnit

BaseTest class biedt helpers

Configuratie standaard aanwezig

Unit & Functionele tests



Tests Uitvoeren

Unit tests:phpunit -c Build/buildessentials/PhpUnit/UnitTests.xml

Functionele tests:phpunit -c Build/buildessentials/PhpUnit/FunctionalTests.xml



Unit / Functional tests

Een unit test...

test een class buiten zijn contexttest kleine ‘units’ code

Een functionele test...

test de class in zijn contexttests dekken het volledige systeem



UnitTestCase Helpers

Mock objecten

getAccessibleMock()getAccessibleMockForAbstractClass()

Dependency Injection

inject()Protected / private

_set()_call()



Dependency Injection

Gebruik injection method indien mogelijk $mockFoo->injectBar($mockBar);

inject() $this->inject($mockFoo, ‘bar’, $mockBar);

AccessibleMock $mockFoo->_set(‘bar’, $mockBar);



FunctionalTestCase

$testableSecurityEnabled

$testableHttpEnabled

$router

$testablePersistenceEnabled

$browser

$objectManager



/** * @test */public function aBlogCanBeCreatedAndPersisted() { $blog = new \TYPO3\T3CON\Test\Domain\Model\Blog(); $blog->setTitle('foo'); $this->blogRepository->add($blog);

$this->persistenceManager->persistAll(); $this->persistenceManager->clearState();

$this->assertEquals(1, $this->blogRepository->countAll());}

Persistence Test



/** * @test */public function getControllerObjectNameIsEmptyIfNoRouteMatchesCurrentRequest() { $this->router = new \TYPO3\Flow\Mvc\Routing\Router(); $request = \TYPO3\Flow\Http\Request::create(

new \TYPO3\Flow\Http\Uri('http://localhost') );

$actionRequest = $this->router->route($request); $this->assertEquals('', $actionRequest->getControllerObjectName());}

HTTP Test



/** * @test */public function administratorsAreAllowedToSeeHiddenRestrictableEntities() { $this->authenticateRoles(array('Administrator'));

$defaultEntity = new Fixtures\RestrictableEntity('default'); $hiddenEntity = new Fixtures\RestrictableEntity('hiddenEntity'); $hiddenEntity->setHidden(TRUE);

// ...

$result = $this->restrictableEntityRepository->findAll(); $this->assertTrue(count($result) === 2);

$this->assertNotNull($this->persistenceManager->getObjectByIdentifier($defaultEntityIdentifier, 'TYPO3\T3CON\Test\Tests\Functional\Security\Fixtures\RestrictableEntity'));

$this->assertNotNull($this->persistenceManager->getObjectByIdentifier($hiddenEntityIdentifier, 'TYPO3\T3CON\Test\Tests\Functional\Security\Fixtures\RestrictableEntity'));

$this->restrictableEntityRepository->removeAll(); $this->persistenceManager->persistAll(); $this->persistenceManager->clearState();}

Security Test



/** * @test */public function formIsRedisplayedIfValidationErrorsOccur() { $this->browser->request('http://localhost/test/fluid/formobjects’); $form = $this->browser->getForm();

$form['post']['email']->setValue('test_noValidEmail');

$this->browser->submit($form); $form = $this->browser->getForm(); $this->assertSame('test_noValidEmail', $form['post']['email']->getValue()); $this->assertSame('f3-form-error', $this->browser->getCrawler()

->filterXPath('//*[@id="email"]')->attr('class'));

$form['post']['email']->setValue('[email protected]');

$response = $this->browser->submit($form); $this->assertSame('Egon Olsen|[email protected]', $response->getContent());}

“Browser” Test

flaws in my initial design.”

“Mijn bug reproduceren met een test? Kan dat? Maar... dan

kan ik dus regressions voorkomen!”




Continues Integration



Tests uitvoeren met Jenkins

Gerrit trigger op patches

Unit tests (evt. functioneel)
