testdouble.js vs TestOOB comparison of testing frameworks
What are the differences between testdouble.js and TestOOB?

	testdouble.js https://github.com/testdouble/testdouble.js	TestOOB https://pypi.org/project/testoob/
Programming language	JavaScript	Python
Category	Unit Testing, Intergration Testing	Unit Testing, unittest Extensions
General info	This library was designed to work for both Node.js and browser interpreters and it encourages the TDD (Test Driven Development) Test doubles can be used with conjuction of other test frameworks such as Jasmine, Jest, Chai, QUnit, Mocha, Tape etc.	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.	Yes It is compatible with xUnit and supportsxUnit XML output	No
Client-side Allows testing code execution on the client, such as a web browser	No	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 Testdouble is primarily used to test server-side functions, behaviours and components	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	N/A	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.	N/A	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.		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)	Yes Testdouble includes inbuilt support for mocking	Yes Mocks are available - testoob can acess library unittest.mock which is used for mocking
Grouping Allows organizing tests in groups	N/A	Yes One can build suites with testoob
