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.	PHPUnit is a unit testing framework for the PHP programming language PHPUnit is a programmer-oriented testing framework and is an instance of the xUnit architecture for unit testing frameworks.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes It's an instance of the xUnit architecture for unit testing frameworks
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 It can perform Unit tests and can test various front-end components and behaviours
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 By performing unit tests on singular back-end components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test		Yes By use of a setup code. The setup code consists of two Important template functions, the 'setUp()' function (called to create the objects to be tested) and 'tearDown()' function (called to cleanup the objects which you tested)
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 It does support group fixtures
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	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 One of its main features is that PHPUnit comes with out of the box support for Mock objects
Grouping Allows organizing tests in groups	Yes You can create test suites with Gauge which can be run using multiple parameters.	Yes It allows grouping of tests and by using the @group annotation one can tag a test to belong to one or more groups
