Wallaby vs Unitils comparison of testing frameworks
What are the differences between Wallaby and Unitils?

	Wallaby https://github.com/elixir-wallaby/wallaby	Unitils http://www.unitils.org/summary.html
Programming language	Elixir	Java
Category	Intergration Testing, Browser Automation	Unit Testing, Intergration Testing
General info	Library for end-to-end intergration testing for Elixir apps Wallaby supports concurrent feature testing (i.e multiple tests can run concurrently) as well as browser management	Unitils is an open source library whose goal is to make unit and integration testing easy and maintainable. Unitils is divided into modules, each of them providing support for a certain aspect of your unit and integration tests. For example if you need mocking for your tests, just include unitils-mock as a dependency, If you would also want to load DbUnit data sets, just include unitils-dbunit
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 It works well for automated E2E testing; Wallaby also has an experimental Chrome Driver that works well	Yes You can perform unit tests on various components and functionality that make up the front-end
Server-side Allows testing the bahovior of a server-side code	N/A	Yes Unitils provides support for testing the back-end through modules such as DbUnit which specifically tests your database, i.e connections setup and so on
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	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
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
Licence Licence type governing the use and redistribution of the software	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)	Yes Available through third party libraries like Mock and Mockery
Grouping Allows organizing tests in groups	N/A
