Arquillian vs stestr comparison of testing frameworks
What are the differences between Arquillian and stestr?

	Arquillian http://arquillian.org/	stestr https://pypi.org/project/stestr/
Programming language	Java	Python
Category	Intergration Testing, Functional Testing	Unit Testing
General info	Arquillian is an Open source framework for writing Integration and functional tests Arquilian comes bundled with many extra tools such as Arquillian graphene, Drone and Selenium to write tests to the visual layer as well	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 It is a xUnit framework	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can perform unit tests on front-end components and functionality	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 You can unit tests on back-end behaviours and functionalities by testing specific back-end classes and functions	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 By use of extensions, for example you can use the Persistence extension to set database fixtures	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 You can define group fixtures	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.	N/A	Yes By using a library like test-generator
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 Arquillian supports mock object functionality you can use third party libraries	N/A
Grouping Allows organizing tests in groups	Yes Arquilian supports grouping of tests	N/A
