- Menta is a testing framework for PHP that provides components and utilities for automating tests using Selenium WebDriver. - It includes components for common tasks like assertions, waiting, taking screenshots. Page object components are used to represent pages under test. - Menta manages Selenium sessions, handles configuration, and integrates with PHPUnit to allow writing and running automated tests. It aims to provide reusable tools for test automation.

A thin layer is good!
But not enough…
no test logic
no higher level

dealing with
Selenium specific tasks
not compatible to
legacy test cases
No abstraction /
