Programming language	.NET	JavaScript
Category	Acceptance Testing	Unit Testing
General info	Gauge is a light-weight cross-platform test automation tool for writing acceptance tests. Gauge is a free and open source framework for writing and running acceptance tests. Some of its key features include: -Simple, flexible and rich syntax based on Markdown.; -Consistent cross platform/language support for writing test code.; -A modular architecture with plugins support.	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.	No	Yes Compatible
Client-side Allows testing code execution on the client, such as a web browser	Yes You can test front-end behaviour by creating testing specifications to test front-end behaviour	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	Yes You can test back-end behaviour by creating testing specifications to test back-end behaviour	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.	N/A

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 You can create mocks using third party libraries like moq	Yes SinonJS is basically a library that we can use to create object mocks for unit testing
Grouping Allows organizing tests in groups	Yes You can create test suites with Gauge which can be run using multiple parameters.
