Needle vs Selenium comparison of testing frameworks
What are the differences between Needle and Selenium?

Needle

Selenium

https://pypi.org/project/selenium/
Programming language

Java

Python

Category

Unit Testing

Web Automation

General info

Needle is a lightweight framework for testing Java EE components outside of the container in isolation

Needle 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

Selenium is an open source tool used to test web applications

Selenium is a powerful testing tool which can send standard Python commands to different browsers, despite variations in browser design. It also provides extensions to emulate user interaction with browsers, a distribution server for scaling browser allocation, and the infrastructure for implementations of the W3C WebDriver specification that lets you write interchangeable code for all major web browsers
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can test front-end components and functionality by testing individual front-end classes and functions

Yes

It is primarily a browser automation tool which tests front-end components and functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test back-end components and functionality.one of needles features is database testing via a JPA (Java Persistence API) like hibernate

Yes

It can perform Unit tests and can test various components and behaviours in the backend using a BDD or TDD approach
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

It has setUp() and tearDown() functions which are mostly used to execute database operations

Yes

By writing your Selenium WebDriver tests in PyTest, this gives you access to Pytest's powerful fixture model
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

The setUp() and tearDown functions can be used to define an environment for a group of tests

Yes

One can group fixtures if accessing Pytest's fixture model
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

Yes

By using a library such as Faker or Fake-factory
Licence
Licence type governing the use and redistribution of the software

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

One of needle's features is automatic injection of mock objects, it supports EasyMock and Mockito out of the box

Yes

It includes support for mocking
Grouping
Allows organizing tests in groups

N/A

Yes

By using the TestNG feature with which we can create groups and maintain them easily
