Very Groovy Browser Automation
Groovy Java HTML

Build Status Maven Central

Geb (pronounced “jeb”) is a browser automation solution. It brings together the power of WebDriver, the elegance of jQuery content selection, the robustness of Page Object modelling and the expressiveness of the Groovy language.

How to contribute

Build Environment

Geb builds with Gradle. You do not need to have Gradle installed to work with the Geb build as Gradle provides an executable wrapper that you use to drive the build.

On UNIX type environments this is gradlew and is gradlew.bat on Windows.

For example to run the Geb test suite for the entire project you would run…

./gradlew test

Contributing Documentation

Geb documentation comes in two forms: the manual and the API (i.e. the Groovydoc amongst the source).

The Manual

The manual project can be found at doc/manual within the project tree. The AsciiDoc source files, CSS and images that make up the manual can be found at doc/manual/src (the manual is compiled using a tool called AsciiDoctor).

Most documentation contributions are simply modifications to these files.

To compile the manual in or to see any changes made, simply run (from the root of the geb project)…

./gradlew :doc:manual:asciidoctor

You will then find the compiled HTML in the directory doc/manual/build/asciidoc

The API reference

The API reference is made up of the Groovydoc (like Javadoc) that annotates the Groovy files for the different modules in module/. To make a change to the reference API documentation, find the corresponding file in module/«module»/src/main/groovy and make the change.

You can then generate the API reference HTML by running…

./gradlew :doc:manual:compileApi

You will then find the compiled HTML in the directory doc/manual/build/manual/api

Note that you can build the manual chapters and reference API in one go with ./gradlew doc:manual:compile

Contributing features/patches

The source code for all of the modules is contained in the module/ directory.

To run the tests after making your change to a module, you can run…

./gradlew :module:«module-name»:test

There are lots of example tests in the geb-core module that use the classes from the test-support module for running against an in memory HTTP server.

To run the entire test suite, run…

./gradlew test
