PHPSpec vs fast-check comparison of testing frameworks
What are the differences between PHPSpec and fast-check?

	PHPSpec https://www.phpspec.net/en/stable/	fast-check https://github.com/dubzzz/fast-check
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	It's a property based testing framework written in typescript Fast-check provides another way to test programs by using property testing, Property testing is a way to test functionality by automatically generating many different inputs. This means Instead of relying on hard-coded inputs and outputs, it checks characteristics of the output given the whole range of possible inputs
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 It can test 'units' of front-end code for functionality and behaviour
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 It is a unit testing framework in essence and can test back-end functionality 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	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	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	N/A
