Chai vs JBehave comparison of testing frameworks
What are the differences between Chai and JBehave?

	Chai https://www.chaijs.com	JBehave https://jbehave.org/
Programming language	JavaScript	Java
Category	Unit Testing	Acceptance Testing
General info	Chai is a BDD / TDD assertion library for Node.js and the browser that can be paired with any JavaScript testing framework. Chai is an assertion library, similar to Node's built-in assert and makes testing easier by giving you many assertions you can run against your code. It also includes a robust Plugin architecture for extending Chai's assertions and interfaces.	JBehave is a Behaviour-Driven Development testing framework for java JBehave is a Behaviour Driven Development framework. It intends to provide an intuitive and accessible way for automated acceptance testing
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 Chai can be used in a browser environment to test front-end components and functionality	Yes You can test front-end behaviour (scenarios) with JBehave
Server-side Allows testing the bahovior of a server-side code	Yes Chai is used in a Node.JS environment to test server behaviour and functionality	JBehave tests scenarios and behaviours of components, it can test back-end behaviour
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 You have a few options for using fixtures in JBehave: you can run your steps before/after each scenario by using LifeCycle: you can use @BeforeStory and @AfterStory annotations or you can define a dummy scenario with your setup/teardown steps
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 You can define group fixtures with JBehave
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 By using chai-spec-generator plugin which will generate chai test specs from a JavaScript object	No
Licence Licence type governing the use and redistribution of the software	MIT License	BSD-style 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 By using by using a third party library like chai-jest-mocks which is a chai plugin that adds assertions for jest mock functions. You can also use sinon.js	The best way to mock is to use third party libraries like Mockito, Jmock or Jmockit
Grouping Allows organizing tests in groups	N/A	N/A
