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

	PHPSpec https://www.phpspec.net/en/stable/	Google Puppeteer https://developers.google.com/web/tools/puppeteer
Programming language	PHP	JavaScript
Category	Unit Testing	Browser Automation
General info	PhpSpec is a testing tool based on the concept of emergent design using specification PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line	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 By testing your PHP classes that run your front-end	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 You can use PHPSpec to test your PHP classes that run your back-end	No
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes You can define fixtures	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 You can define 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.	Yes There are methods that act as generators	No
Licence Licence type governing the use and redistribution of the software	Free	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)	Yes It has built in support for Mocks	No
Grouping Allows organizing tests in groups	In PHPspec, you can group specification files by a certain namespace in a suite	No
