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

	Testify https://github.com/stretchr/testify	ExUnit https://hexdocs.pm/ex_unit/ExUnit.html
Programming language	Go	Elixir
Category	Unit Testing	Unit Testing
General info	A set of golang packages that has many tools for testing Go code Testify is a Go testing framework that has some great features like easier assertions, Test suite Interfaces, and Mocks	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
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes xUnit has the ExUnit framework as an instance
Client-side Allows testing code execution on the client, such as a web browser	Yes Yes, since it is also easily hooked to 'testing' package it is used to test front-end components	Yes Front-end code can be tested using ExUnit, Phoenix front-end framework for Elixir uses ExUnit as the default testing framework
Server-side Allows testing the bahovior of a server-side code	Yes Yes it can also be used to test back-end components and functionality	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
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 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
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 Group fixures are possible with this library
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 Generators are found in the StreamData module
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 Its 'mock' package has a mechanism for easily writing mock objects that are used in place of real objects	Yes Mocks are available for use with ExUnit through the Mock module. Also available through the use of third party libraries like mecktest
Grouping Allows organizing tests in groups	Yes Using the 'suite' package developers can build a test suite as a struct build teardown and setup methods as well as testing methods on the struct then run them with 'go test'	Yes Using the 'describe' function which goups tests together. Every describe block recieves a name which is used as a prefix for upcoming tests
