Test::Unit vs stestr comparison of testing frameworks
What are the differences between Test::Unit and stestr?

	Test::Unit https://test-unit.github.io/	stestr https://pypi.org/project/stestr/
Programming language	Ruby	Python
Category	Unit Testing, Intergration Testing	Unit Testing
General info	Test::Unit is a unit testing framework for Ruby Test::Unit is an implementation of the xUnit testing framework for ruby which is used for Unit Testing. However Test::Unit has been left in the standard library to support legacy test suites therefore if you are writing new test code use Minitest instead of Test::Unit	stestr is a Python test runner designed to execute unittest test suites stestr executes unittest test suites by using multiple processes to split up execution of a test suite then stores a history of all test runs to help in debugging failures and optimizing the scheduler to improve speed.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes test-unit is a xUnit family unit testing framework for Ruby	No
Client-side Allows testing code execution on the client, such as a web browser	It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components	Yes Stestr being a test runner that runs unittest tests, it can test fron-tend functionality and behaviour.
Server-side Allows testing the bahovior of a server-side code	Yes	Yes Stestr being a test runner that runs unittest tests, it can run back-end tests for 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 Fixture methods are available through its ClassMethods Module	Yes By use of a third party library like Fixture
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 Group fixture methods are supported	By use of a third party library like Fixture
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.	No	Yes By using a library like test-generator
Licence Licence type governing the use and redistribution of the software	LGPLv2.1, Ruby Licence	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)	No	N/A
Grouping Allows organizing tests in groups	No	N/A
