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

	Shoulda https://github.com/thoughtbot/shoulda	EvoSuite http://www.evosuite.org/
Programming language	Ruby	Java
Category		Unit Testing
General info	Meta gem containing Shoulda Context and Shoulda Matchers Shoulda contains two other gems: Should Context and Shoulda Matchers. Should Context allows better naming and grouping of your tests. Shoulda Matchers provides a set of "matchers", i.e. methods that allow you to write much more concise assertions.	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	N/A	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	N/A	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)	N/A	No
Grouping Allows organizing tests in groups	Yes	Yes Suites are generated automatically in evosuite
Other Other useful information about the testing framework	Shoulda Context is compatible with Minitest and Test::Unit. Shoulda Matchers is compatible with RSpec and Minitest.
