Testing ''is '' software development. Software development is writing code. Testing makes sure the code actually works, so in a nutshell: '''Testing is software development''' :-)
Software development is writing code. Testing makes sure the code actually works, so in a nutshell: One major aspect of testing - especially '''Testing is software developmentduring''' :-)==Phan==see development and the [[Continuous Integration]] process, is [[Phanstatic analysis]].<blockquote>Program testing can be used to show the presence of bugs, but never to show their absence!<ref>https://en.wikiquote.org/wiki/Edsger_W._Dijkstra</ref>

PHPStan seems more polished (perhaps because it's commercial and has a 'pro' version that adds a GUI) whereas phan is the original PHP static analysis tool Rasmus Ledorf uses. PHPStan has some very notable projects that integrate it: Symphony, Doctrine, Monolog, and many more. Once again, there are PHPStan integrations for Drupal and Wordpress, but not MediaWiki. Adding a configuration file for your MediaWiki extension is straightforward and would look like this:<syntaxhighlight lang="yaml">parameters: level: 1 paths: - src - tests scanDirectories: - ../../includes - ../../tests/phpunit - ../../vendor</syntaxhighlight> The * [[https://phpstan.org/user-guide/rule-levels '''level''' can be 0 - 9Software Quality]] and are "intuitive" with zero being the lowest "lax" level, and 9 being the highest level of strictness. This is the opposite of Phan levels where zero is the highest level of strictness. The '''paths''' are the directories of '''your code.''' The '''scanDirectories''' are additional paths used to discover symbols, but not analyze for errors. For more advanced usage, see * [[Ansible#Testing|Ansible [https://github.com/ProfessionalWiki/Maps/blob/ee88211fadb3573b646cce005383450e96c3054e/phpstan.neon the example of Professional Wiki's Maps extensionTesting]]] which illustrates configuration file includes of a 'baseline'; error message suppression; and directory exclusions of problem code. ===Psalm===https://psalm.dev/ <references />
