Twenty Years of Web Testing: From Selenium's Dawn to Vitest's Promise
summary
A twenty-year timeline names Selenium, JS Test Driver (circa 2007), Karma (2011) and Jest (eclipsing Karma around 2016) and shows concrete wins and failures: phantomjs crashes make Karma brittle in CI, node‑based runners remove the JVM overhead, Jest struggles with ESM and custom compilers, and headless Chrome fixes stability but not transform drift. Vitest arrives as an environment‑aware runner that reuses build config so transforms match production, reducing false positives and actually working for many modern frameworks.
