General info

Wallaby.js is an integrated continuous testing tool for JavaScript.

Wallaby.js runs your tests immediately as you change your code (you don’t even have to save the file) and reports code coverage and other results directly to your code editor. Its also uses various techniques such as dependency analysis to only execute tests affected by your code changes and parallel test execution to ensure your tests run as fast as possible.

Minimal testing framework, compatible with Test::Unit/MiniTest

xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

Client-side
Allows testing code execution on the client, such as a web browser

Yes

Wallaby.js can test front-end components and functionality

Server-side
Allows testing the bahovior of a server-side code

Yes

Wallaby.js can test server behaviour and functionality

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

N/A

FreeBSD 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)

By use of a third party library Jest works well with wallaby

Grouping
Allows organizing tests in groups
