Modern UI Test Automation with Selenium Libraries

End-to-end testing is a common testing methodology where the objective is to test how an application works by checking user scenarios from start to finish. Usually, it is not that easy to write and maintain these tests. Fortunately, we have Selenium, a rock-solid ecosystem where you can find almost everything for UI automation, both for web and mobile testing.
In this live stream, we will talk about modern approaches to UI test automation with Selenium and Java. Let’s see if setting up e2e tests is easy or not, and how we can do it better.

Yuriy has been developing libraries, frameworks, and tools for developers for the past 10 years. As part of his academic activities, he mentored Applied Mathematics students at Samara University.
As a member of the JetBrains IntelliJ IDEA team, Yuriy is fascinated with introducing useful new tools to the daily routine of millions of developers. He is the author of the Selenium UI Testing plugin and maintainer of Gauge support for IntelliJ IDEA.

5. Java is Here! — https://www.jetbrains.com/lp/devecosystem-2020/testing/ 5
6. Selenium Basics — Selenium is: 1. Ecosystem of UI testing tools 2. User-agent library 3. Contiuous integration tools 6
7. Getting Started — 1. Install Selenium plugin for IntelliJ IDEA 2. Create a new project 3. Write tests! 7
8. 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
9. 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
10. 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
11. Page Object Pattern — Main advantages: 1. Separate tests from page specific code 2. Single repository for operations offered by the page 11
12. 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
13. Reporting Libraries — Put your tests in order with reporting library: 1.Allure Framework 2.Serenity BDD 13
14. Mobile Testing — You can still use Java for mobile testing with: 1.Appium 2.Selenide with Appium 14
15. Running Selenium on CI Server — 1.Web browser on a host 2.Selenium Grid v3 or v4 3.Selenoid 4.Cloud Services 15
16. 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
17. 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
18. 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
19. Perfect UI Automation Stack — ⬠ Java/Kotlin ⬠ Gradle ⬠ Selenide ⬠ Allure Framework ⬠ Selenoid No more custom frameworks needed! 19
