Description
In this episode, learners are guided through writing Behat functional tests in Sylius — step by step, from writing a .feature file using Gherkin to implementing and refactoring the test in PHP. Behat is the BDD (Behavior-Driven Development) engine at the heart of Sylius's business-facing test layer.
We cover:
- creating and exploring .feature scenarios,
- checking which steps are already defined and implementing missing ones,
- debugging undefined step and no matching step definition errors,
- working with Context classes and Transformers, which convert input like order numbers to domain objects,
- using Page Object Pattern via Symfony Pages for interacting with the UI,
- best practices in naming, modularization, and test structure,
- advanced debugging techniques (tag filtering, running single scenarios, Symfony container inspection).
This episode provides a complete foundation for writing automated, business-readable tests with Behat in Sylius.
