Matomo quality assurance
QA Tools
- Travis Continuous Integration
Travis CI is our continuous integration build server. It runs tests (unit, plugins, integration, screenshot, piwik.js tests) as soon as there is a commit in the Git repository.
When tests pass, Travis is Green and when tests fail Travis is Broken. The build artifacts are uploaded to builds-artifacts.piwik.org.
Learn How Matomo (Piwik) uses Travis CI to deliver a reliable analytics platform to the community - All Matomo (Piwik) Core developers aim to write tests along with new features and changes to Matomo (TDD). We have hundreds of test cases which are easy to maintain and update. If you’re a developer, you can easily run the unit, integration and screenshot tests, learn all about our tests in tests/README [hackers only]
