Programming language	PHP	Kotlin
Category	Browser Automation	Acceptance Testing, Unit Testing
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.	Spek is a specification framework for Kotlin Spek is a Kotlin-based Specification Testing framework for the JVM. It works as a JUnit 5 Test Engine meaning that we can easily plug it into any project that already uses JUnit 5 to run alongside any other tests that we might have.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	N/A	No
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 Yes you can test front-end behaviour by writing specifications to test front-end functionality. Developers can also write unit tests for individual front-end components.
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 behaviour and componets by writing specifications to test back-end functionality and unit tests for individual back-end components
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 Fixtures are available in spek through functions suchas beforeEachTest() and afterEachTest()
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 spek has group fixtures available through the beforeGroup() and afterGroup() functions

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 Laravel provides helpers for mocking events, jobs, and facades out of the box or use Mockery or PHPUnit to create your own mocks or spies	Yes You can use the third party library mockito-kotlin
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.	Yes Tests are written using nested lambdas, each scope (level) can either be a group or a test
