Behat vs Google Puppeteer comparison of testing frameworks
What are the differences between Behat and Google Puppeteer?

	Behat https://docs.behat.org/en/latest/	Google Puppeteer https://developers.google.com/web/tools/puppeteer
Programming language	PHP	JavaScript
Category	Functional/Acceptance Testing	Browser Automation
General info	Behat is an open source Behavior-Driven Development framework for PHP. Behat uses the StoryBDD subtype of behaviour-driven development (the other subtype is SpecBDD); This means the tests we write with Behat look rather like stories than code. It is inspired by Ruby's Cucumber	Puppeteer is a Node library which provides browser automation for chrome and chromium Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium; It provides a high-level API to control Chromium or Chrome over the DevTools Protocol
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes To enable Behat to test a website, you need to add Mink and a browser emulator (selenium maybe, though slow) to the mix. Mink methods are the connector between Behat and an extensive list of available drivers, and they provide a consistent testing API.	Yes Most things you can do manually in the browser can be done using puppeteer, therefore you can create a testing environment for your tests to run directly. You can test front-end functionality such as UI testing with puppeteer
Server-side Allows testing the bahovior of a server-side code	Yes Behat can be used for Data Integrity Testing to verify that database operations are functioning properly	No
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes One can use the 'Doctrinefixturesbundle' to create the required fixture loaders and load them in our Behat scenarios when required, using the 'BeforeScenario' hook.	N/A
Group fixtures Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.	Yes Behat allows for group fixtures	N/A
Generators Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.	By use of third party libraries like moodle-behat-generators	No
Licence Licence type governing the use and redistribution of the software	MIT License	Apache License 2.0
Mocks Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)	By using third party libraries like Mock and Prophecy	No
Grouping Allows organizing tests in groups	Yes You can use tags to group features and scenarios together, independent of your file and directory structure	No
