Being Good At Waiting
summary
Demonstrates concrete waiting strategies for AJAX in Selenium: uses HTMLUnit with a server delay of 0.5–4s, contrasts naive sleep with a homemade polling loop, explains pros/cons of implicit waits and the preferred WebDriver explicit wait (custom ExpectedConditions, 200ms poll). For zero–side‑effect validations shows injecting/patching JavaScript to override XMLHttpRequest and read jQuery.active; these hooks work in examples but aren’t foolproof for complex concurrent requests.
