Selenium Basics — Selenium is: 1. Ecosystem of UI testing tools 2. User-agent library 3. Contiuous integration tools 6 

Getting Started — 1. Install Selenium plugin for IntelliJ IDEA 2. Create a new project 3. Write tests! 7 

Setting up Driver Binary — 1. Download webdriver binary, compatible with a local browser 2. Specify path to webdriver binary in tests: System.setProperty(“webdriver.chrome.driver”, “/path/to/binary/chromedriver”); No way! We can do this better with WebDriverManager: io.github.bonigarcia:webdrivermanager:4.4.3 Must-have library for managing drivers! 8 

Modern APIs on top of Selenium — Top 3 productive APIs to write your UI tests: 1.Selenide (Java/Kotlin/Groovy) 2.FluentLenium (Java/Groovy) 3.Geb (Groovy) 9 

Selenide — 1.Concise fluent APIs 2.AJAX support 3.Powerful selectors 4.Simple configuration 5. WebDriverManager Out-of-the-box See github.com/jreznot/intellij-selenide-example 10 

Page Object Pattern — Main advantages: 1. Separate tests from page specific code 2. Single repository for operations offered by the page 11 

Kotlin for UI Testing — Most useful Kotlin features for UI testing: 1.Extension functions 2.DSLs: let{}, apply{}, with{} 3.Type inference and implicit casts 4.Null-safety 5.Data classes 6.String templates 12 

Reporting Libraries — Put your tests in order with reporting library: 1.Allure Framework 2.Serenity BDD 13 

Mobile Testing — You can still use Java for mobile testing with: 1.Appium 2.Selenide with Appium 14 

Running Selenium on CI Server — 1.Web browser on a host 2.Selenium Grid v3 or v4 3.Selenoid 4.Cloud Services 15 

Selenoid — 1. Enables you to run web browsers in Docker 2. Implements Selenium Hub protocol 3. Easy to install 4. Easy to share browsers setup with browsers.json config 16 

Running Test with Selenoid — Start Selenoid in Docker: https://hub.docker.com/u/selenoid > docker run -d \ --name selenoid \ -p 4444:4444 \ -v /var/run/docker.sock:/var/run/docker.sock \ -v /your/directory/config/:/etc/selenoid/:ro \ aerokube/selenoid:latest-release Selenide: Configuration.remote = "http://localhost:4444/wd/hub"; 17 

Selenoid UI — Provides status pages and VNC access to running web browsers under test. > docker run -d --name=selenoid-ui --link selenoid -p 8080:8080 aerokube/selenoid-ui --selenoid-uri http://selenoid:4444 18 

Perfect UI Automation Stack — ⬠ Java/Kotlin ⬠ Gradle ⬠ Selenide ⬠ Allure Framework ⬠ Selenoid No more custom frameworks needed! 19
