Real-world examples of production bugs include UTF-8 issues, Unix timestamp errors, null values, dark mode failures, and floating-point inaccuracies.
A visual analysis of 334 bugs collected over two years reveals monthly trends and a surprising peak in bug occurrences during June.
Bugs are categorized into major types like UI and backend logic, with UI bugs being the most common, particularly in responsiveness, templating, and glitching.
Adopting a mobile-first design philosophy and using end-to-end testing frameworks like WebdriverIO and Playwright can prevent common responsiveness issues.
Techniques like dogfooding, exploratory testing, and heatmap visualization help identify unexpected glitches and user friction points like dead clicks and rage clicks.
Unresolved placeholders in text and emails can be prevented by implementing unit and integration tests that include assertions to check for missing values.
Exposing raw error messages and stack traces creates security vulnerabilities and poor user experience, so they should be replaced with generic messages in production.
