PHPSpec vs Wallaby.js comparison of testing frameworks
What are the differences between PHPSpec and Wallaby.js?

	PHPSpec https://www.phpspec.net/en/stable/	Wallaby.js https://wallabyjs.com/
Programming language	PHP	JavaScript
Category	Unit Testing	Unit Testing
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	Wallaby.js is an integrated continuous testing tool for JavaScript. Wallaby.js runs your tests immediately as you change your code (you don’t even have to save the file) and reports code coverage and other results directly to your code editor. Its also uses various techniques such as dependency analysis to only execute tests affected by your code changes and parallel test execution to ensure your tests run as fast as possible.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	N/A
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 Wallaby.js can test front-end components and functionality
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	Yes Wallaby.js can test server behaviour and functionality
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	N/A
Licence Licence type governing the use and redistribution of the software	Free	N/A
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	By use of a third party library Jest works well with wallaby
Grouping Allows organizing tests in groups	In PHPspec, you can group specification files by a certain namespace in a suite
