Codeception: introduction to php testing
2 likes2,765 views
This document introduces Codeception, an open source PHP testing framework. It discusses different types of testing like unit, integration, functional, and acceptance testing. Codeception uses PHPUnit, Symfony browserkit, Selenium, and PhantomJS to test PHP applications. The document demonstrates running Codeception tests and provides examples of passing and failing tests. It also discusses how Codeception allows testing JavaScript-heavy applications using Selenium or headless testing with PhantomJS. Continuous integration and Docker/Vagrant are presented as ways to improve testing workflows.

Codeception: introduction to php testing
- 1. Codeception Introduction to PHP testing Thomas Dutrion / @tdutrion - September 2014
- 2. About me ● Founder and developer/architect at Engineor ● Working with PHP since 2003 ● Trying to work properly... @tdutrion / @engineor / [email protected]
- 3. PHP3: simple web pages PHP4: object? are you kidding? PHP5: mature language, with namespaces, real objects and so on… What is missing to compete with other languages? TESTABILITY Codeception PHP best practice: industrialisation
- 4. ● Unit testing ● Integration testing ● Functional testing ● Acceptance testing ● Mutation testing ● Monkey testing ● ... Codeception What can we test? And you, how are you testing?
- 5. ● Small unit of code ● SOLID principle (single Responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion) ● Requires complete isolation ● Long to write, requires continuous updates, expensive => very good for critical parts of the application! Codeception Unit testing
- 6. ● Test modules as groups ● Simulate input ● Less work than Unit testing (smaller number of tests) Codeception Integration testing
- 7. ● Test final application appearance ● Reproduce complete application execution ● Client point of view ● Less code, final result only, help on legacy projects => Can be used to prove the completion of the project Codeception Acceptance testing
- 8. Codeception One tool: Codeception
- 9. General introduction Codeception History: ● Started in 2011 ● Stable release in January 2012 ● Version 2.0.5 in August 2014! ● Currently 2725 commits ● 175 contributors... Problem solved: ● Bridge between all testing types ● No other languages required ● Extensible ● Covers major frameworks
- 10. PHP 5.4 minimum!!!! (you can do that, right!) Codeception
- 11. You already know it! Based on recommended and proven tools ● PHPUnit ● Symfony browserkit ● Selenium / PhantomJS (optional) ● … Test suite written in PHP => no need to learn another language. Codeception
- 12. Follow the quickstart! 1. Install codeception (prefer using composer, globally or in dev only) 2. Bootstrap (directories and files structure, basic configuration) 3. Generate acceptance testing 4. Write tests 5. And run! Codeception Acceptance testing 101
- 13. $ php vendor/bin/codecept run Codeception PHP Testing Framework v2.0.5 Powered by PHPUnit 4.2.5 by Sebastian Bergmann. Acceptance Tests (1) ------------------------------------------------------------------------------------------------------------ Trying to ensure that frontpage works (WelcomeCept) Ok --------------------------------------------------------------------------------------------------------------------------------- Functional Tests (0) --------------------------------------------------------------------- Unit Tests (0) --------------------------------------------------------------------------- Time: 382 ms, Memory: 8.50Mb OK (1 test, 1 assertion) Codeception Basic example results (pass)
- 14. Acceptance Tests (1) ------------------------------------------------------------------------------------------------------------ Trying to ensure that frontpage works (WelcomeCept) Fail There was 1 failure: 1) Failed to ensure that frontpage works in WelcomeCept (/Users/thomas/NetBeansProjects/Codeception01/tests/acceptance/WelcomeCept. php) Couldn't see "Not ok": Failed asserting that / → Your HTML code here [Content too long to display.

Codeception Basic example results (fail)
- 15. ● Since 2005, AJAX is everywhere (XmlHttpRequest) ● New architecture: MVVM javascript in front, PHP/node… in back Testing problem: PHPBrowser / Curl can not read javascript modifications. => Codeception can work with Selenium! Codeception What about sexy frontends?
- 17. ● No Firefox and or java on your servers => no Selenium on CI ● CI usually run only simple bash scripts ● Need to run the test in command line, emulating an headless browser => Codeception PhantomJS driver Codeception Headless testing for Continuous Integration
- 19. Workflow improvement ● Use Docker containers or Vagrant virtual boxes to add development, testing Codeception and production servers configuration to your VCS repository ● Add CI server triggered on commits, with email results
- 20. Questions? Special thanks to / reading recommendation: ● Jeremy Coates (@phpcodemonkey) for Testing with codeception ● PHPNW (@phpnw), great PHP group that made me discover Codeception ● All of you for your patience and supporting my French accent! ● Glasgow PHP (@glasgowphp) to let me talk here Please rate and comment this talk on SlideShare: http://goo.gl/uJIh7G Codeception: introduction to PHP testing, by Thomas Dutrion from Engineor for Glasgow PHP, September 2014
