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

	Espec https://github.com/antonmi/espec	EvoSuite http://www.evosuite.org/
Programming language	Elixir	Java
Category	Unit Testing	Unit Testing
General info	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)	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
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 Front-end components can be tested; there is also espec_phoenix for the Phoenix web framework	Yes You can test front-end code by testing the classes that provide front-end functionality
Server-side Allows testing the bahovior of a server-side code	Yes databases and server behaviour can be tested using Espec	Yes You can test server-side functionality and components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	You can write your own fixtures but no inbuilt fixtures are provided
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	MIT License	GNU 2.1 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)	Yes It has a Built-in mocking functionality on top of Erlang 'meck' library	No
Grouping Allows organizing tests in groups	Yes By use of context blocksand tags functions	Yes Suites are generated automatically in evosuite
