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

	Google Puppeteer https://developers.google.com/web/tools/puppeteer	Jnario http://jnario.org/
Programming language	JavaScript	Java
Category	Browser Automation	Acceptance Testing, Unit Testing
General info	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	Jnario is a test framework for Java focusing on the design and documentation aspects of testing Jnario is based on Xtend and consists of two domain-specific languages, one for writing readable acceptance tests, the other for succinct unit tests. Together they are well suited for behavior-driven development of Java programs.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It is an xUnit type testing framework
Client-side Allows testing code execution on the client, such as a web browser	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	Yes You can write scenarios to test various front-end behaviours using 'Given', 'When', 'Then' steps to describe simple scenarios
Server-side Allows testing the bahovior of a server-side code	No	Yes You can write unit tests to test server side behaviours and components using Jnario specs
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 It contains the Setup & Teardown functions similar to JUnit but less verbose
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 The Setup & Teardown functions can be used as 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.	No	N/A
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	Eclipse Public License v1.0
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)	No	Yes You can implement mocking through the use of a third partylibrary like Mockito
Grouping Allows organizing tests in groups	No	Yes Jnario Suites allows you to group multiple specifications into suites and execute them together, you do this using the suite wizard
