go-smtp-mock¶
go-smtp-mock is a Go package designed to simulate an SMTP server for testing purposes.^[600-developer__smtp.md]
It provides developers with a mock environment to verify email sending logic without requiring a live mail server or risking the delivery of test emails to real recipients.
Key Features¶
- Protocol Simulation: It functions as a simulated [[smtp|Simple Mail Transfer Protocol]] server, implementing standard interactions expected of an SMTP endpoint^[600-developer__smtp.md].
- Testing Utility: As a mock tool, it allows for the validation of application behavior related to email generation and transmission^[600-developer__smtp.md].
- Go Integration: The package is specifically designed for the Go programming language, facilitating integration into Go-based test suites^[600-developer__smtp.md].
Usage Context¶
This tool is typically used within automated testing frameworks. By intercepting SMTP requests, it enables developers to assert that their applications correctly format and send email messages according to the protocol's specifications^[600-developer__smtp.md], such as handling commands like HELO/EHLO, MAIL FROM, and RCPT TO^[600-developer__smtp.md].
