💡TL;DR
If a fix only works on your laptop, it is not a fix. It is a temporary illusion.
A lot of bugs survive because we test in the exact environment where we built the feature. Same browser, same cached data, same .env, same DB shape, same user role.
Then it goes to staging or production and breaks immediately.
Real habit to build:
Before marking anything “done”, test at least these:
- fresh login
- different role or permission
- empty state
- bad input
- mobile view
- slow network or failed API case
Most production issues do not come from complex logic.
They come from untested assumptions.
