Test automation & Seleniun by oren rubin
The document discusses test automation and Selenium. It begins by explaining the differences between unit tests and end-to-end tests, then introduces Selenium as a tool for writing end-to-end tests across different browsers. It covers Selenium best practices like page object modeling and using Selenium Grid for parallel testing across browsers and devices. It also discusses techniques like visual validation using Applitools and recording and playback of tests.
