General info

Lens is a unit-testing framework for PHP

Lens is a unit-testing framework for PHP that needs no assertions

JasUnit is a slim unit testing framework for JavaScript, following the general design principles of xUnit.

For testing your code, JasUnit allows you to: Create test fixtures with any number of test methods; Implement setup() and teardown() methods which are run before and after each test; Specify a namespace for a fixture for easy organisation of tests; Use the default or custom logger (default appends results to a given element); Use assertions from any scope - this isn't necessary or even really advised, but some people prefer it.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

Yes

JasUnit follows the general design principles o xUnit
Client-side
Allows testing code execution on the client, such as a web browser

Yes

It can test front end components

Yes

JasUnit is primarily used to test front-end code and functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

It can test back-end behaviour

No

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

With JasUnit you can Create test fixtures with any number of test methods Implement setup() and teardown() methods which are run before and after each test
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

JasUnit allow you to create 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

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)

It provides inbuilt Mocking capabilities
Grouping
Allows organizing tests in groups
