General info

Lighttest is a JavaScript unit-testing library — it works both in browsers and under Node.js, supports flow control, and is focused on keeping the tests clear.

Lighttest keeps tests clear by using a minimal syntax of the test cases, and the only testing function, lighttest.check(), is used to indicate a success or a failure. Any testing behaviour can be implemented using this function JavaScript natively meaning no additional testing API is required.

Behat is an open source Behavior-Driven Development framework for PHP.

Behat uses the StoryBDD subtype of behaviour-driven development (the other subtype is SpecBDD); This means the tests we write with Behat look rather like stories than code. It is inspired by Ruby's Cucumber
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

Light Test works in the browser to test client side components and behaviours

Yes

To enable Behat to test a website, you need to add Mink and a browser emulator (selenium maybe, though slow) to the mix. Mink methods are the connector between Behat and an extensive list of available drivers, and they provide a consistent testing API.
Server-side
Allows testing the bahovior of a server-side code

Yes

Light Test works with NodeJs to test back-end environments behaviours and components in short it can test any behaviour in the back-end as well as the front-end

Yes

Behat can be used for Data Integrity Testing to verify that database operations are functioning properly
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

One can use the 'Doctrinefixturesbundle' to create the required fixture loaders and load them in our Behat scenarios when required, using the 'BeforeScenario' hook.
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

Behat allows for 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

By use of third party libraries like moodle-behat-generators
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

By using third party libraries like Mock and Prophecy
Grouping
Allows organizing tests in groups

N/A

Yes

You can use tags to group features and scenarios together, independent of your file and directory structure
