EvoSuite vs Espec comparison of testing frameworks
What are the differences between EvoSuite and Espec?

	EvoSuite http://www.evosuite.org/	Espec https://github.com/antonmi/espec
Programming language	Java	Elixir
Category	Unit Testing	Unit Testing
General info	EvoSuite is a tool that automatically generates unit tests for Java software EvoSuite is a tool that automatically generates test cases with assertions for classes written in Java code by applying a hybrid approach that generates and optimizes whole test suites towards satisfying a coverage criterion	BDD driven testing framework for Elixir It is a testing framework written from scratch which is inspired by RSpec and the main idea is to close to its perfect DSL (Domain Specific Language)
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end code by testing the classes that provide front-end functionality	Yes Front-end components can be tested; there is also espec_phoenix for the Phoenix web framework
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side functionality and components	Yes databases and server behaviour can be tested using Espec
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	You can write your own fixtures but no inbuilt fixtures are provided	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.	N/A	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.	N/A	N/A
Licence Licence type governing the use and redistribution of the software	GNU 2.1 License	MIT License
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	Yes It has a Built-in mocking functionality on top of Erlang 'meck' library
Grouping Allows organizing tests in groups	Yes Suites are generated automatically in evosuite	Yes By use of context blocksand tags functions
