Development & Testing

• Get an API key at: https://haveibeenpwned.com/API/Key
• Set HIBP_API_KEY=<your api key> in .env file
• If using VS Code:
  • Use the Testing tab to run tests, it should pick up the API key as environement variable to run tests that require the API key.
• If others:
  • Use make tests
