Wallaby vs Codedeception comparison of testing frameworks
What are the differences between Wallaby and Codedeception?

	Wallaby https://github.com/elixir-wallaby/wallaby	Codedeception https://codeception.com/
Programming language	Elixir	PHP
Category	Intergration Testing, Browser Automation	Unit Testing, Acceptance Testing/Functional Testing
General info	Library for end-to-end intergration testing for Elixir apps Wallaby supports concurrent feature testing (i.e multiple tests can run concurrently) as well as browser management	Codeception is a full-stack testing framework for PHP It is inspired by BDD and provides a way of writing acceptance, functional and even unit tests. It is powered by PHPUnit.
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 It works well for automated E2E testing; Wallaby also has an experimental Chrome Driver that works well	Yes One is able to write acceptance tests which are used to look at functionality from a user's perspective. It is able to look at pages in browser (Chrome, Firefox or PhpBrowser)
Server-side Allows testing the bahovior of a server-side code	N/A	Yes It supports back-end tests, by writing functionaltests one can be able to test server behaviour
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 One can define a fixture and write the test with Codedeception, use the yii2-codedeceptionextention which will autoload fixtures for you
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 One can define group fixtures
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	MIT License	MIT 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)	Yes Available through third party libraries like Mock and Mockery	Yes Codeception provides Codeception\Stub library for building mocks and stubs for tests
Grouping Allows organizing tests in groups	N/A	Yes Codeception consists of three so-called “suites”: A “unit suite” for all unit tests, a “functional suite” for all functional tests, and an “acceptance suite” for all acceptance tests.
