General info

Laravel Dusk is an easy-to-use browser automation and testing API.

One can use Dusk to programmatically test applications, visit any website using a real Chrome browser, automate repetitive tasks, scrape information from other sites or test to make sure your app always works in the browser.

Kiwi is a Behavior Driven Development library for iOS development

The goal behind Kiwi is to provide a BDD library that is simple to setup and use, and create tests that are more readable than what is possible with the bundled test framework.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

Yes

Kiwi is an xUnit style framework
Client-side
Allows testing code execution on the client, such as a web browser

Yes

It is a browser automation tool which tests front-end components and functionality

Yes

You can test front-end components with kiwi
Server-side
Allows testing the bahovior of a server-side code

Yes

Laravel provides a variety of tools to make it easier to test your database driven applications

Yes

You can test back-end components with kiwi
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

Yes

kiwi has a beforeEach(aBlock) which is run before every 'it' block in all enclosed contexts. Code that sets up the particular context should go here and afterEach(aBlock) which is run after every it block in all enclosed contexts
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

Yes

through the beforeAll(aBlock) and afterAll(aBlock) functions.

Mocks

Yes

Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks
Grouping
Allows organizing tests in groups

Yes

Using the 'dusk' which command accepts any argument that is normally accepted by the PHPUnit test runner, allowing you to run the tests for a given group.
