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. |
Needle is a lightweight framework for testing Java EE components outside of the container in isolationNeedle reduces the test setup code by analysing dependencies and has automatic injection of mock objects by default. Therefore It will maximize the speed of development as well as the execution of unit tests |
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 |
YesChai can be used in a browser environment to test front-end components and functionality |
YesYou can test front-end components and functionality by testing individual front-end classes and functions |
Server-side
Allows testing the bahovior of a server-side code |
YesChai is used in a Node.JS environment to test server behaviour and functionality |
YesYou can test back-end components and functionality.one of needles features is database testing via a JPA (Java Persistence API) like hibernate |
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test |
N/A |
YesIt has setUp() and tearDown() functions which are mostly used to execute database operations |
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 |
YesThe setUp() and tearDown functions can be used to define an environment for a group of tests |
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. |
YesBy using chai-spec-generator plugin which will generate chai test specs from a JavaScript object |

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) |
YesBy 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 |
YesOne of needle's features is automatic injection of mock objects, it supports EasyMock and Mockito out of the box |
Grouping
Allows organizing tests in groups |
