What are the differences between Wallaby and Test::Unit?

Wallaby

https://github.com/elixir-wallaby/wallaby

Test::Unit

https://test-unit.github.io/
Programming language

Elixir

Ruby

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

Test::Unit is a unit testing framework for Ruby

Test::Unit is an implementation of the xUnit testing framework for ruby which is used for Unit Testing. However Test::Unit has been left in the standard library to support legacy test suites therefore if you are writing new test code use Minitest instead of Test::Unit
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

test-unit is a xUnit family unit testing framework for Ruby
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

It could have tested some front-end components but its now legacy hence wouldn't work with the many new front-end components
Server-side
Allows testing the bahovior of a server-side code

N/A

Yes

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

Fixture methods are available through its ClassMethods Module
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 fixture methods are supported
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

No

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

No

Grouping
Allows organizing tests in groups

N/A
