ExUnit vs JSSpec comparison of testing frameworks
What are the differences between ExUnit and JSSpec?

	ExUnit https://hexdocs.pm/ex_unit/ExUnit.html	JSSpec https://github.com/jsspec/jsspec
Programming language	Elixir	JavaScript
Category	Unit Testing	Unit Testing
General info	Unit testing framework for Elixir. Elixir comes bundled with ExUnit allowing developers to use all elixir features without compromising unit tests. It uses a TDD workflow, and shows one message per test	Javascript BDD (Behaviour Driven Development) based test runner/framework Contextualised spec runner for JavaScript in the flavour of RSpec (Ruby Spec runner). JSSpec has got 2 really powerful features which helps you to make unit testing easier: 1) Shared examples 2) Shared contexts
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes xUnit has the ExUnit framework as an instance	No
Client-side Allows testing code execution on the client, such as a web browser	Yes Front-end code can be tested using ExUnit, Phoenix front-end framework for Elixir uses ExUnit as the default testing framework	Yes JSSpec is primarily used for testing front-end/client-side components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes ExUnit tests backend code. Typically Unit tests will be written not to interact with the browser, but with ExUnit you can test whichever part of your application	No
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes ExUnit has a library called ExUnitFixtures fixtures are functions that are run before a test is run to setup the test environment or provide the test with data	N/A
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 fixures are possible with this library	N/A
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.	Yes Generators are found in the StreamData module	N/A
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	N/A
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 Mocks are available for use with ExUnit through the Mock module. Also available through the use of third party libraries like mecktest	Yes It has a module doubles (mocks/spies) for mocking and spying
Grouping Allows organizing tests in groups	Yes Using the 'describe' function which goups tests together. Every describe block recieves a name which is used as a prefix for upcoming tests	N/A
