JUnit vs Google Puppeteer comparison of testing frameworks
What are the differences between JUnit and Google Puppeteer?

	JUnit https://junit.org/junit5/	Google Puppeteer https://developers.google.com/web/tools/puppeteer
Programming language	Java	JavaScript
Category	Unit Testing, Regression Testing	Browser Automation
General info	JUnit is an open source Unit testing framework for java JUnit is useful for developers to write and run repeatable tests. JUnit has been crucial in the development of test driven development and is partof the xUnit family of unit testing frameworks	Puppeteer is a Node library which provides browser automation for chrome and chromium Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium; It provides a high-level API to control Chromium or Chrome over the DevTools Protocol
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It is an instance of the xUnit architecture for unit testing frameworks.	No
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end components such as individual classes and functions that create the front-end	Yes Most things you can do manually in the browser can be done using puppeteer, therefore you can create a testing environment for your tests to run directly. You can test front-end functionality such as UI testing with puppeteer
Server-side Allows testing the bahovior of a server-side code	Yes You can test classes and functions that compose the back-end such as database connections and so on	No
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes JUnit contains a setUp() method, which runs before every test invocation and a tearDown() method, which runs after every test method.	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 You can use setUp() and tearDown() inbuilt functions as group fixtures.	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.	You can use JUnit-quickcheck to generate test data	No
Licence Licence type governing the use and redistribution of the software		Apache License 2.0
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)	JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects.	No
Grouping Allows organizing tests in groups	Yes In JUnit you can create a test suite that bundles a few unit test cases and runs them together. You use both @RunWith and @Suite annotation are used to run the suite test.	No
