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

	Wallaby.js https://wallabyjs.com/	Atoum http://atoum.org/
Programming language	JavaScript	PHP
Category	Unit Testing	Unit Testing
General info	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.	Atoum is a unit testing framework specific to the PHP language Atoum is similar to SimpleTest and is designed to be implemented rapidly, simplify test development and allow for writing reliable, readable, and clear unit tests
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	N/A	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Wallaby.js can test front-end components and functionality	Yes Autom can perform unit tests on various front-end components and behaviours
Server-side Allows testing the bahovior of a server-side code	Yes Wallaby.js can test server behaviour and functionality	Yes Autom can perform unit tests on servers/back-end components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	Yes By using the 'given()' method to setup your environment
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.	N/A	Yes By using the 'given()' method to setup your environments
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.	N/A	N/A
Licence Licence type governing the use and redistribution of the software	N/A	Atoum License
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 use of a third party library Jest works well with wallaby	Yes By use of autom mocks which are decoupled and easier to maintain
Grouping Allows organizing tests in groups		Yes By use of an extension for autom called blackfire which allows you to write blackfire test suites.
