Selenium and the Four Rules of Simple Design
summary
Transforms a brittle Selenium test suite into a maintainable set of tests by applying four concrete rules: tests always pass (checks before and after each change), express intent (rename long method names into readable actions), no duplication (extract repeated strings and logic), and small (extract setup, search, locate, add to bag, assert helpers). The demo runs the suite, times are shown (around 12–19 seconds), commits after each refactor, and ends with helpers hiding Selenium details.
