RSpec vs Laravel Dusk comparison of testing frameworks
What are the differences between RSpec and Laravel Dusk?

	RSpec https://rspec.info	Laravel Dusk https://laravel.com/docs/5.8/dusk
Programming language	Ruby	PHP
Category	Unit Testing, Intergration Testing	Browser Automation
General info	Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks.	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification.	N/A
Client-side Allows testing code execution on the client, such as a web browser	Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that.	Yes It is a browser automation tool which tests front-end components and functionality
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side behaviour with Rspec	Yes Laravel provides a variety of tools to make it easier to test your database driven applications
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes RSpec does contain fixture methods	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.	Yes Group fixture methods are supported	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.	Yes RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	MIT 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)	Yes Available through rspec-mocks gem.	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
Grouping Allows organizing tests in groups	Yes Allows declaring example groups and contexts.	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.
