The document outlines best practices for unit testing in PHP, emphasizing the importance of solitary versus sociable unit tests and their respective advantages and disadvantages. It also discusses the implementation of a continuous integration environment using tools like Jenkins, and strategies for optimizing test execution to ensure reliability and minimize errors. Additionally, it addresses the setup and configuration of CI servers, as well as useful plugins for enhancing the testing and building process.

- 3. Globalcode – Open4education Schedule Tests Pyramid Solitary Unit Test x Sociable Unit Test Optimizations for Running Tests PHP Continuous Integration Environment
- 4. Globalcode – Open4education Tests Pyramid Goal: To provide an adequate tests proportion to run and a quick feedback. Unit Tests: To verify the quality at small code snippets (units). e.g., PHPUnit Integration Tests: To test the integration of the tested units. e.g., PHPUnit + DBUnit UI Tests (User Interface Tests): To validate flows and information displayed at the user level. e.g., Selenium Webdriver

- 6. Globalcode – Open4education Solitary Unit Test x Sociable Unit Test What is a unit test? Concept more used and defended: Solitary Unit Test: Methods are tested in isolation from other internal methods and external communications using mocks. Mock: It’s a change of a real structure to a simulated structure for running tests.
- 7. Globalcode – Open4education Solitary Unit Test x Sociable Unit Test Solitary Unit Test Controller Model Database Controller Model(Mock) Unit
- 8. Globalcode – Open4education Solitary Unit Test x Sociable Unit Test Solitary Unit Test Advantages: Quick execution. Faster error location. Exception simulation. Disadvantages: Possible outdated mock. False positive at tests. Possible bug at production.
- 9. Globalcode – Open4education Solitary Unit Test x Sociable Unit Test What is a unit test? Less known concept: Sociable Unit Test : Methods are tested in collaboration from other internal methods and external communications. What is unit in this case? It depends on the depth of your test.
- 10. Globalcode – Open4education Unit Solitary Unit Test x Sociable Unit Test Sociable Unit Test Controller Model Database
- 11. Globalcode – Open4education Solitary Unit Test x Sociable Unit Test Sociable Unit Test Advantages: Running tests with the real structure. More thoroughly tested scenario (units collaboration). Disadvantages: Slower runtime. High dependence among components or systems. False negative at tests ( e.g., external communications ).
- 12. Globalcode – Open4education Solitary Unit Test x Sociable Unit Test What kind of unit test is best? It’s necessary to review each case depending on the need and use one of two test types. What about the tests pyramid with the sociable unit tests? http://martinfowler.com/bliki/UnitTest.html TOO CONFUSING!!!!
- 13. Globalcode – Open4education Optimizations for Running Tests What is important for running tests? It must pass confidence that code is reliable. It must be easy to understand. The suite execution must be as fast as possible, so that it runs as soon as possible and many times as necessary. (e.g., every commit )
- 14. Globalcode – Open4education Optimizations for Running Tests Environment Optimizations Problems that can delay the running tests: Network concurrence. Database concurrence. Possible solution: To centralize the testing environment on a single machine, either virtual or real with its own database for testing.
- 15. Globalcode – Open4education Optimizations for Running Tests Environment Optimizations STAGING DATABASE LOCAL TEST DATABASE BEFORE AFTER
- 16. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – Unit Tests @dataProvider : Creating a data provider to produce entries for a test.
- 17. Globalcode – Open4education Optimizations for Running Tests Without @dataProvider
- 18. Globalcode – Open4education Optimizations for Running Tests With @dataProvider
- 19. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests setUp e tearDown At the suite execution, it prevents multiple browsers stay open if several tests fail.
- 20. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests setUpBeforeClass e tearDownAfterClass What if instead, the browser was opened and closed once at each test class?
- 21. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests Surefire Plugin (Running tests in parallel)
- 22. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests Results – Build #73 (Using setUp and tearDown)
- 23. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests Results – Build #75 (Using setUpBeforeClass and tearDownAfterClass)
- 24. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests Results – Build #75 (Using setUpBeforeClass and tearDownAfterClass)
- 25. Globalcode – Open4education Optimizations for Running Tests Code Optimizations – UI Tests Results – Build #76 (parallel tests)
- 26. Globalcode – Open4education PHP Continuous Integration Environment What is a continuous integration environment? Continuous Integration Agile process. It defends the continuous code delivery in a central repository in a short time. The code to be integrated can’t produce defects at the existing code. (tests) The continuous integration environment aims to automate tasks of the continuous integration process. Automation is important to decrease the errors of human nature.
- 27. Globalcode – Open4education PHP Continuous Integration Environment Monitoring Central repository with version control CI SERVER
- 28. Globalcode – Open4education PHP Continuous Integration Environment How does create a basic continuous integration (CI) server for PHP? Verification and Updating of Repository Copy Running Tests Building Package
- 29. Globalcode – Open4education PHP Continuous Integration Environment How does create a basic continuous integration (CI) server for PHP? CI Tool (Jenkins, Hudson, etc..) It’s the heart of continuous integration server, where whole code integration process, tests and building packages is done. Versioning Control (GIT, SVN, etc...) The CI server will verify the central repository from time to time checking if there was a change. If there is a change, a building will be triggered and the local copy is updated.
- 30. Globalcode – Open4education PHP Continuous Integration Environment How does create a basic continuous integration (CI) server for PHP? PHP/PHPUnit Running tests to validate the integrated code. Web Server (Apache) and Database (MySQL, SQLite, etc...) Support for sociable unit tests, integration tests and UI tests. Building Tool (Maven, Ant, etc...) Building packages.
- 31. Globalcode – Open4education PHP Continuous Integration Environment Thanks champs!!! So now I’ll install everything manually!!!! “IT’S RIGHT!!”! :P
- 32. Globalcode – Open4education PHP Continuous Integration Environment Jenkins can manage the installation of most components through PLUGINS. It can manage multiple component versions. Easy installation, removal or upgrade.

- 35. Globalcode – Open4education PHP Continuous Integration Environment Other useful plugins: Clover PHP Code coverage chart for each building. Warnings when code coverage decreases.
- 36. Globalcode – Open4education PHP Continuous Integration Environment Other useful plugins: Clover PHP
- 37. Globalcode – Open4education PHP Continuous Integration Environment Other useful plugins: HTML Publisher PHPUnit Log: It provides code coverage charts of each folder, class or method. Covered and discovered lines information and dead code.
- 38. Globalcode – Open4education PHP Continuous Integration Environment Other useful plugins: HTML Publisher
- 39. Globalcode – Open4education PHP Continuous Integration Environment The continuous integration process within Jenkins is represented by Job. A job can be configured in a very varied way, could represent a step in the continuous integration, like whole continuous integration process. It’s possible to change the step execution order within a job through a simple “drag and drop”.
