EvoSuite vs WebdriverIO comparison of testing frameworks
What are the differences between EvoSuite and WebdriverIO?

	EvoSuite http://www.evosuite.org/	WebdriverIO https://webdriver.io/
Programming language	Java	JavaScript
Category	Unit Testing	Browser Automation, Unit Testing, Functional Testing
General info	EvoSuite is a tool that automatically generates unit tests for Java software EvoSuite is a tool that automatically generates test cases with assertions for classes written in Java code by applying a hybrid approach that generates and optimizes whole test suites towards satisfying a coverage criterion	WebdriverIO is the next-gen WebDriver test framework for Node.js made upon Selenium WebdriverIO is written in JavaScript and uses Selenium under the hood. It also comes with its own inbuilt test runner and supports other testing frameworks like Jasmine, Cucumber, and Mocha
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end code by testing the classes that provide front-end functionality	Yes WebdriverIO allows the use of advanced CSS selectors and makes it easy to find elements for front-end testing
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side functionality and components	Yes It can be used to test server side 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	You can write your own fixtures but no inbuilt fixtures are provided	Yes WebdriverIO supports the creation of fixtures
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 WebdriverIO supports the creation of group fixtures
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	N/A
Licence Licence type governing the use and redistribution of the software	GNU 2.1 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)	No	Yes It contains a mocking service called 'wdio-wiremock-service'
Grouping Allows organizing tests in groups	Yes Suites are generated automatically in evosuite	Yes WebdriverIO allows one to build test suites, you can run these test in parallel and organize them by adjusting the 'maxInstances' property in your config file
