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

	Needle http://needle.spree.de/	Windmill https://pypi.org/project/windmill/
Programming language	Java	Python
Category	Unit Testing	UI Testing
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	Windmill is an Open Source Web UI testing framework for Python Windmill is an Open Source AJAX Web UI testing framework that implements in-browser recording and playback, cross browser testing and test integration
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 Its main function is testing of 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	No
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	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 The setUp() and tearDown functions can be used to define an environment for a group of tests	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.	N/A	Yes By using third party libraries
Licence Licence type governing the use and redistribution of the software	GNU Lesser General Public License v2.1	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)	Yes One of needle's features is automatic injection of mock objects, it supports EasyMock and Mockito out of the box	N/A
Grouping Allows organizing tests in groups	N/A	N/A
