Behat vs DOH comparison of testing frameworks
What are the differences between Behat and DOH?


Programming language




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

D.O.H means Dojo Objective Harness, it's a test framework for the DOJO web apps which tests and runs on the browser and on cloud test execution services like Browserstack

Dojo is a Typescript framework build for modern web application, and D.O.H is a basically unit test library to test JavaScript functions and custom widgets
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.



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


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.


DOH is both flexible and extendable and runs in many environments including many browsers to test various front-end functionalities and components
Allows testing the bahovior of a server-side code


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


Pieces of back-end code can be tested with DOH as it performs Unit tests. It is flexible enough to test server-side behaviour and functionality
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


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

It has various fixture methods like setUp(), tearDown() and Performance test fixtures which are just like a regular test fixtures, but with extra options. Specifically, it uses 'testType' to mark it as a "perf" test, which instructs the D.O.H. runner to treat the tests as performance and use the calibrate and execute test runner
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.


Behat allows for group fixtures


It supports group fixtures
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.

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


Allows organizing tests in groups


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


There is a function that allows you to group tests, the 'doh.register(...)' function. It's most commonly used for registering Unit Tests
