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

Its main function is testing of front-end components and functionality

Yes

Autom can perform unit tests on various front-end components and behaviours
Server-side
Allows testing the bahovior of a server-side code

No

Yes

Autom can perform unit tests on servers/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

N/A

Yes

By using the 'given()' method to setup your environment
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.

N/A

Yes

By using the 'given()' method to setup your environments
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.

Yes

By using third party libraries

N/A

Licence

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)

N/A

Yes

By use of autom mocks which are decoupled and easier to maintain
Grouping
Allows organizing tests in groups

N/A

Yes

By use of an extension for autom called blackfire which allows you to write blackfire test suites.
