Level 37: Achieve 50% Code Coverage

Aim to achieve at least 50% code coverage on your own. This means at least half of your code should be executed by your tests.

• Run npm run test:coverage to see your current coverage percentage
• Add tests for routes and edge cases you haven’t covered yet
• Focus on testing:
  • All your GET routes
  • POST routes with valid and invalid data
  • Error cases (404, 400 validation errors)
  • DELETE operations

Goal: Reach at least 50% coverage across statements, branches, and functions. Getting 100% is often unrealistic, but 50-70% is a good target for most projects.
