Peridot vs pytest comparison of testing frameworks
What are the differences between Peridot and pytest?

	Peridot http://peridot-php.github.io/	pytest https://docs.pytest.org/en/latest/
Programming language	PHP	Python
Category	Unit Testing	Unit Testing
General info	Peridot is a lightweight, extensible testing framework for PHP It features an event-driven architecture that allows testers to easily customize the framework via plugins and reporters, and uses the 'describe-it', syntax making the testing language clear and readable	Pytest is the TDD 'all in one' testing framework for Python Pytest is a powerful Python testing framework that can test all and levels of software. It is considered by many to be the best testing framework in Python with many projects on the internet having switched to it from other frameworks, including Mozilla and Dropbox. This is due to its many powerful features such as ‘assert‘ rewriting, a third-party plugin model and a powerful yet simple fixture model.
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 Front-end components can be tested with Peridot	Yes pytest can test any part of the stack including front-end components
Server-side Allows testing the bahovior of a server-side code	Yes Back-end componets and behaviours can be tested as small units	Yes pytest is powerful enough to test database and server components and functionality
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes Peridot has several methods that allow one to create and define fixtures	Yes Pytest has a powerful yet simple fixture model that is unmatched in any other testing framework.
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 There are methods to create group fixtures in Peridot	Yes Pytest's powerful fixture model allows 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.	N/A	Yes pytest has a hook function called pytest_generate_tests hook which is called when collecting a test function and one can use it to generate data
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)	Peridot does not include mocking out of the box but there are some great tools like 'Mockery' and 'Prophecy' which Peridot intergrates very well with	Yes By either using unittest.mock or using pytest-mock a thin wrapper that provides mock functionality for pytest
Grouping Allows organizing tests in groups	Yes By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.	Yes Tests can be grouped with pytest by use of markers which are applied to various tests and one can run tests with the marker applied
