Codedeception vs testdouble.js comparison of testing frameworks
What are the differences between Codedeception and testdouble.js?

	Codedeception https://codeception.com/	testdouble.js https://github.com/testdouble/testdouble.js
Programming language	PHP	JavaScript
Category	Unit Testing, Acceptance Testing/Functional Testing	Unit Testing, Intergration Testing
General info	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.	This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development) Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is compatible with xUnit and supportsxUnit XML output
Client-side Allows testing code execution on the client, such as a web browser	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)	No
Server-side Allows testing the bahovior of a server-side code	Yes It supports back-end tests, by writing functionaltests one can be able to test server behaviour	Yes Testdouble is primarily used to test server-side functions, behaviours and components
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 define a fixture and write the test with Codedeception, use the yii2-codedeceptionextention which will autoload fixtures for you	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 One 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.	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 Codeception provides Codeception\Stub library for building mocks and stubs for tests	Yes Testdouble includes inbuilt support for mocking
Grouping Allows organizing tests in groups	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.	N/A
