Behat vs TestOOB comparison of testing frameworks
What are the differences between Behat and TestOOB?

	Behat https://docs.behat.org/en/latest/	TestOOB https://pypi.org/project/testoob/
Programming language	PHP	Python
Category	Functional/Acceptance Testing	Unit Testing, unittest Extensions
General info	Behat is an open source Behavior-Driven Development framework for PHP. Behat uses the StoryBDD subtype of behaviour-driven development (the other subtype is SpecBDD); This means the tests we write with Behat look rather like stories than code. It is inspired by Ruby's Cucumber	Testoob is an advanced unit testing framework for Python. Testoob integrates with existing unittest test suites. It contains many features like: a filter which tests to run with regular expressions, output test results as XML/HTML/PDF, test skipping, color output on a terminal and more.
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 To enable Behat to test a website, you need to add Mink and a browser emulator (selenium maybe, though slow) to the mix. Mink methods are the connector between Behat and an extensive list of available drivers, and they provide a consistent testing API.	Yes Testoob can test front-end features since it is a unit testing tool. One can write a test for each function that is on the client side
Server-side Allows testing the bahovior of a server-side code	Yes Behat can be used for Data Integrity Testing to verify that database operations are functioning properly	Yes Testoob can test back-end functionality since it is a unit testing tool. One can write a test for each function in the 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 One can use the 'Doctrinefixturesbundle' to create the required fixture loaders and load them in our Behat scenarios when required, using the 'BeforeScenario' hook.	Yes TestOOB extends unittest and prepares fixtures by use of the 'setUp() function just like unittest
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 Behat allows for group fixtures	Yes The 'setUp()' function allows you to group your initialization functions
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.	By use of third party libraries like moodle-behat-generators	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	Apache License 2.0
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)	By using third party libraries like Mock and Prophecy	Yes Mocks are available - testoob can acess library unittest.mock which is used for mocking
Grouping Allows organizing tests in groups	Yes You can use tags to group features and scenarios together, independent of your file and directory structure	Yes One can build suites with testoob
