Automated Tests—Your Safety Net
Automated testing is a way to check if your code and databases work as expected—like running a checklist before takeoff. First, write simple tests that confirm your most important functions do their job. Next, add tests for new features as you build, so problems don’t sneak in. Finally, treat failures as alerts, not disasters—they’re early warnings that save you stress and cost down the road.
Version Control—Your Project’s Safety Net
Version control is a history book for your code and databases. Each change is a page you can revisit, undo, or learn from. First, make small, frequent commits with clear messages, so you always know what changed and why. Next, use branches for experiments—this keeps the main project stable. Finally, if mistakes happen, don’t panic; version control lets you rewind without losing days of work.
