What are the differences between Test’em and PHPSpec?

	Test’em https://github.com/testem/testem	PHPSpec https://www.phpspec.net/en/stable/
Programming language	JavaScript	PHP
Category	Unit Testing	Unit Testing
General info	A Unit testing test runner for JavaScript Test'em is framework agnostic and has support for Jasmine, Qunit, Mocha and others through custom test framework adapters. It canalso run tests on all major browsers as well as Node and Phantomjs	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
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	It has an xUnit reporter	No
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
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
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
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
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
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
Grouping Allows organizing tests in groups		In PHPspec, you can group specification files by a certain namespace in a suite
