Developers face challenges in generating and managing test user data at scale, especially for applications with email verification or multi-user testing.
Key challenges include email verification bottlenecks, temporary data persistence issues, automation limitations, domain restrictions, and the need for testing multi-user scenarios.
Solutions include setting up local SMTP servers, using email API services like Mailosaur or Mailtrap, and implementing dedicated testing email management solutions for persistent and scalable email accounts.
Best practices involve creating email accounts programmatically, storing credentials securely, cleaning up test data, implementing timeout handling, and documenting the test email strategy.
