Testing desktop apps with selenium
This document discusses how Avast, an antivirus software company, overcame challenges in testing their desktop application user interfaces (UIs) by using Selenium. It outlines how Avast connects Selenium to their applications via the Chromium Embedded Framework (CEF) to access and control the application structure as if it were a website. This allows them to build a powerful testing framework and run UI tests across different environments like daily short tests on Linux servers and longer tests on virtual Windows machines. The presentation provides code examples and a demo of connecting Selenium to an Avast application.

- 7. Avast architecture andtesting possibilities ■ Antivirus engine − C++, assembler ▪ integration/component ▪ e2e tests in python ▪ using boost framework − No UI testing needed
- 8. Avast architecture andtesting possibilities ■ Avast GUI frameworks ▪ Avast UI page looks like a website − Htmlayout ▪ renderer of HTML layout content for old parts of UI ▪ untestable by standard methods :( ▪ partial success with Sikuli − CEF ▪ new parts of UI ▪ allows to use selenium webdriver for testing We used to fail in UI automation testing :(
- 9. Motivation and ideaoutline ■ GUI testing tools are often image based − Too clumsy − Very inflexible − One small change in GUI requires several changes in tests 9 - Motivation and idea outline ■ Tests require too much maintenance ■ Solution − Testing tool that can access the base structure of GUI − Allows framework creation ■ We have that in Web testing
