Testing best practices are habits that professional developers follow to keep their code reliable and easy to maintain.
Writing tests is important, but writing good tests is even more important.
Well-written tests make your codebase stronger and save time in the long run.
By following testing best practices, students can develop professional-level testing skills.
Key Testing Best Practices
- Write tests for every important function
- Keep tests small and focused
- Use clear and meaningful test names
- Test one thing at a time
- Avoid repeating test code
- Run tests after every change
- Fix failing tests immediately
These habits make testing simple, effective, and powerful.
This test checks many things at once.
If one fails, it is hard to know what exactly went wrong.
Here, each test focuses on only one function.
This makes debugging easier and tests more reliable.
These examples show how following testing best practices improves code quality.
By developing these habits, students gain the mindset of professional developers who write clean, reliable, and maintainable JavaScript applications — a key skill for becoming job-ready.
