ALEX

Automata Learning EXperience (ALEX) is an extension of LearnLib that allows you run automated tests on web applications and JSON-based REST APIs using active automata learning.

Users model Selenium- or HTTP-based test inputs for their application, which are used to automatically infer an automaton model (a Mealy machine), which represents the behavior of the web application.
