Programming language

JavaScript

Category

Functional/Acceptance Testing

Unit Testing

General info

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

Tyrtle is a Javascript unit testing framework that emphasises simplicity, cleanliness and expressiveness.

Tyrtle runs either in the browser or on NodeJS. In a CommonJS environment (eg: Node, or the browser running RequireJS), nothing is added to the global space, and with plain Javascript in the browser, only one variable is added to the window object. This keeps it clean and ensures that it won't interfere with your codebase.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

N/A

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

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.

Yes

Front-end pieces of code can be tested, you can test various components and functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

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

Yes

Back-end components and functions can be tested using tyrtle
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

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.

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.

Yes

Behat allows for group fixtures

N/A

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.

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

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)

By using third party libraries like Mock and Prophecy

Yes

By using Myrtle, a sister project of Tyrtle which provides various Mocking features such as: -Mocking (spying and stubbing functions); -Mock function generation; -Timer manipulation-Speed profiling
Grouping
Allows organizing tests in groups

Yes

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