General info

Spek is a specification framework for Kotlin

Spek is a Kotlin-based Specification Testing framework for the JVM. It works as a JUnit 5 Test Engine meaning that we can easily plug it into any project that already uses JUnit 5 to run alongside any other tests that we might have.

Laravel Dusk is an easy-to-use browser automation and testing API.

One can use Dusk to programmatically test applications, visit any website using a real Chrome browser, automate repetitive tasks, scrape information from other sites or test to make sure your app always works in the browser.
