Continuous integration

Continuous integration (CI) is the concept of running tests and checks on each push, to reduce different risks related to the development cycle.

Motivation

• Be proactive rather than reactive
• Identify hotspots
• Reduce the risk of bugs and regressions

Goal: Code quality is not allowed to decrease.

Parts

1. Syntax check
2. PSR-12
3. Type check
4. Unused variables
5. Tests
   1. Unit tests
   2. Functional tests (with fixture)
   3. Integrity tests (with scripted browser)

Todo:
