What Geb is
Geb is a free, open source browser automation tool for scripting, screen scraping, general automation, and web or acceptance testing. It combines WebDriver and Groovy with jQuery-inspired content selection and Page Object modelling. Its Navigator API lets scripts select and move through page content with CSS selectors, attribute matchers, indexes, and chained operations. For asynchronous page content, Geb offers configurable waitFor clauses and implicit waiting.
Geb works with browsers supported by WebDriver, including remote drivers for automating browsers on another machine. For headless operation, it can use the in-process Java browser emulator HTMLUnit with WebDriver. Integration modules are available for Spock, JUnit, TestNG, and Cucumber via Cucumber JVM. The project documents Gradle and Maven integrations and says Geb can work with any build system.
Geb Core is available as a single geb-core JAR from Maven Central and can be added through Groovy Grape, Maven, or Gradle. It is licensed under Apache License, Version 2.0, and supported by the Apache Software Foundation and the Groovy community. Support channels include the geb-users mailing list, GitHub Discussions, and Groovy Slack’s #geb channel. Geb is listed for Linux, macOS, web, and Windows.
