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

tap-producing test harness for node and browsers.

Tape API is a small superset of the node core assert module
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

It does support xUnit output
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 write tests for any part of your front-end code to test any component or functionality
Server-side
Allows testing the bahovior of a server-side code

N/A

Yes

With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

No

Tape contains only the essential features for making assertions on your code but there is a package called redtape that extends tape to give you beforeEach and afterEach functionality
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

No

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

Licence

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

Tape is a minimalistic framework that provides only essential features to make your assertions about your code
Grouping
Allows organizing tests in groups

N/A

No

Tape contains only the essential features for making assertions on your code
