Testing

jest

• JavaScript testing framework developed by Facebook
• Great for testing both backend and frontend
• Built-in assertion libraries and mocking functionalities
• Easy to use!

Backend

• Routes:

  • Test routes behave as expected
  • Response status
  • Response data
  • Works with database as expected (GET, PUT, POST, DELETE calls)

• Database:

  • Test database behaves as expected
  • Add data to database
  • Update data in database
  • Delete data in database

Frontend

• Components
  • Test if components appear
  • Test if props are as expected
• Functionalities
  • Buttons and client interactions perform/update UI as expected

Let's try it out!

• Clone either the MongoDB or Postgres reference solution
• cd into a directory with cd client or server
• Run npm install --legacy-peer-deps in command line
• Run npm test in command line
