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

	PHPSpec https://www.phpspec.net/en/stable/	teenytest https://github.com/testdouble/teenytest
Programming language	PHP	JavaScript
Category	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	Teenytest is a simple, zero-config test runner for NodeJS Teenytest's CLI will run tests with zero public-API and zero configuration
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It supports xUnit output
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	No
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 Teenytest tests database connections and other server-side components and behaviour
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	Yes It provides fixtures with the methods beforeAll(),afterEach() and afterAll()beforeAll() creates the browser and gives you a newPage() globalafterEach() will close any pages you created with newPage()afterAll() closes the browser
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	Yes Teeny test supports grouping of 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.	Yes There are methods that act as generators
Licence Licence type governing the use and redistribution of the software	Free	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 It has built in support for Mocks	N/A
Grouping Allows organizing tests in groups	In PHPspec, you can group specification files by a certain namespace in a suite	Yes Grouping is supported through nested tests in which any object can contain any combination of hooks, test functions, and additional sub-test objects.
