Geb Browser Automation Test Generator

Description

--- name: geb-skill description: > Generates Geb browser automation tests in Groovy with Spock integration. jQuery-like content DSL and page object pattern. Use when user mentions "Geb", "Groovy test", "GebSpec", "Browser.drive". Triggers on: "Geb", "GebSpec", "Groovy browser test", "Browser.drive". languages: - Groovy category: e2e-testing license: MIT metadata: author: TestMu AI version: "1.0" --- # Geb Automation Skill For TestMu AI cloud execution, see [reference/cloud-integration.md](reference/cloud-integration.md) and [shared/testmu-cloud-reference.md](../shared/testmu-cloud-reference.md). ## Core Patterns ### Basic Test (Spock) ```groovy import geb.spock.GebSpec class LoginSpec extends GebSpec { def "login with valid credentials"() { when: to LoginPage emailInput.value("[email protected]") passwordInput.value("password123") loginButton.click() then: at DashboardPage welcomeMessage.text().contains("Welcome") } def "login shows error for invalid credentials"() { when: to LoginPage emailInput.value("[email protected]") passwordInput.value("wrong") loginButton.click() then: at LoginPage errorMessage.displayed errorMessage.text().contains("Invalid") } } ``` ### Page Objects ```groovy class LoginPage extends geb.Page { static url = "/login" static at = { title == "Login" } static content = { emailInput { $("#email") } passwordInput { $("#password") } loginButton { $("button[type='submit']") } errorMessage(required: false) { $(".error") } } } class DashboardPage extends geb.Page { static url = "/dashboard" static at = { $(".dashboard").displayed } static content = { welcomeMessage { $(".welcome") } userName { $(".user-name") } } } ``` ### Navigator API ```groovy $("css-selector") $("div", class: "active") $("input", name: "email") $("div.items li", 0) // First match $("div.items li").size() // Count // Actions element.click() element.value("text") element << "text" // Append text element.text() element.displayed element.@href // Attribute ``` ### Cloud: `driver = new RemoteWebDriver(new URL(gridUrl), caps)` ## Setup: Gradle with `geb-spock` and `selenium-support` dependencies ### Cloud Execution on TestMu AI Set environment variables: `LT_USERNAME`, `LT_ACCESS_KEY` ```groovy // GebConfig.groovy environments { lambdatest { driver = { def ltOptions = [ user: System.getenv("LT_USERNAME"), accessKey: System.getenv("LT_ACCESS_KEY"), build: "Geb Build", name: "Geb Test", platformName: "Windows 11", video: true, console: true, network: true, ] def caps = new ChromeOptions() caps.setCapability("LT:Options", ltOptions) new RemoteWebDriver( new URL("https://hub.lambdatest.com/wd/hub"), caps) } } } ``` Run: `./gradlew test -Dgeb.env=lambdatest` ## Run: `./gradlew test` ## Deep Patterns See `reference/playbook.md` for production-grade patterns: | Section | What You Get | |---------|-------------| | §1 Project Setup | build.gradle, GebConfig.groovy, environments, waiting config | | §2 Page Objects | Content DSL, at checks, modules for reusable components | | §3 Spec Tests | Spock integration, data-driven with @Unroll, @Stepwise flows | | §4 Waiting & Async | Waiting presets, JavaScript interaction, alerts/confirms | | §5 Advanced Patterns | File upload/download, windows, frames, custom extensions | | §6 API Testing | REST API specs with Groovy JsonSlurper | | §7 CI/CD Integration | GitHub Actions with headless Chrome, Gradle caching | | §8 Debugging Table | 12 common problems with causes and fixes | | §9 Best Practices | 14-item Geb testing checklist |
