What are the differences between Atata and Sinon.js?

	Atata https://atata.io/	Sinon.js https://sinonjs.org/
Programming language	.NET	JavaScript
Category		Unit Testing
General info	Atata is a C# / .NET test automation framework for web Atata is an open source test framework that uses fluent object pattern. It consists of the following concepts: components (controls and page objects), attributes of the control search, settings attributes, triggers, verification attributes and methods	Standalone test stubs and mocks for JavaScript. Works with any unit testing framework. Sinon.js is a great library when you want to unit test your code with supports spies, stubs, and mocks. The library has cross browser support and also can run on the server using Node.js.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes You can use Atata with xUnit frameworks	Yes Compatible
Client-side Allows testing code execution on the client, such as a web browser	Yes Atata is based on selenium and is used for browser automation. You can test various front-end functionalities and behaviours	Yes Sinon.js is a good library for unit testing your front-end code and has cross browser support
Server-side Allows testing the bahovior of a server-side code	No	Yes Sinon.js can run on node.js to test back-end components and server-side 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
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.
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.

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 SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping Allows organizing tests in groups
