Testing Email Sending in Haskell Without Actually Sending Emails
2025-04-21
This article demonstrates how to test email sending functionality in Haskell without actually sending emails, using test spies. By replacing the email sending function with a stub that records function call arguments and checking the recorded information in the test assertion phase, you can effectively test side effects, making tests faster and more reliable. This method avoids reliance on real services, leading to more isolated and faster tests.
