Behat is a test framework for behavior-driven development written in the PHP programming language. Behat was created by Konstantin Kudryashov and its development is hosted on GitHub.

Contents

Purpose

Behat is intended to aid communication between developers, clients and other stakeholders during a software development process. It allows the clear documentation of testable examples of the software's intended behaviour. Behat test scenarios are written with Gherkin, [2] a business-readable domain-specific language following defined patterns.

Benefits

Tests can be run at any point new code is introduced into a codebase to confirm no regressions within the existing test coverage are introduced. It can be used to directly test php code and is often used with Selenium to remote control browsers as part of the scenarios. The browsers under remote control can take videos [3] or screenshots of failures. Using selenium or tools like selenoid [4] a "grid" of browsers can be remote controlled for parallel test execution. There is also a module for running php only scenarios. [5]

Like other BDD frameworks, Behat scenarios are a series of Given, When, and Then steps that explain a business case. The definition of these steps exist within method annotations of a class that extends the BehatContext. [6]

Behat can output test results in a number of different formats, including JUnit XML and HTML [7]

Examples

The preconditions after "Given" correspond to the PHP method name to execute:

Feature: Simple description of this feature’s story  Describe benefit, role and feature or user story  Use as many lines as neededBackground:    Given some step run for all scenariosScenario: Scenario or example description    Given I setup preconditions with:      | data column 1 | data column 2 |      | alice         | bob           |When I press the "blue" buttonThen the result is:"""    A multiple line    string of data"""    #comments can be added as neededScenario Outline: Scenario or example description    Given I setup config with "<setting>"When I push button "<button>"Then "<result>" happensExamples:      | setting | button | result           |      | a       | red    | there is a beep  |      | b       | blue   | there is no beep |

In software testing, test automation is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that would be difficult to do manually. Test automation is critical for continuous delivery and continuous testing.

Selenium is an open source umbrella project for a range of tools and libraries aimed at supporting browser automation. It provides a playback tool for authoring functional tests across most modern web browsers, without the need to learn a test scripting language. It also provides a test domain-specific language (Selenese) to write tests in a number of popular programming languages, including JavaScript (Node.js), C#, Groovy, Java, Perl, PHP, Python, Ruby and Scala. Selenium runs on Windows, Linux, and macOS. It is open-source software released under the Apache License 2.0.

Cucumber is a software tool that supports behavior-driven development (BDD). Central to the Cucumber BDD approach is its ordinary language parser called Gherkin. It allows expected software behaviors to be specified in a logical language that customers can understand. As such, Cucumber allows the execution of feature documentation written in business-facing text. It is often used for testing other software. It runs automated acceptance tests written in a behavior-driven development (BDD) style.

It generates cross-platform client and server bindings for many languages. Most common usage scenarios include connecting services in a microservices style architecture, or connecting mobile device clients to backend services.
