Winni Neessen	127cfdf2bc	Fix error variable declaration in eml.go ... The error variable declaration has been corrected from "if err := parseEML(...)" to "if err = parseEML(...)". This change ensures consistency with the rest of the error handling code in the file.	2024-10-24 13:20:09 +02:00
Winni Neessen	7ed23bf01b	Remove outdated client test cases ... Removed obsolete and redundant client test cases that were no longer relevant. This cleanup improves code maintainability and readability by eliminating excessive, unused test methods.	2024-10-24 12:53:37 +02:00
Winni Neessen	0310527eb5	Completed client.go tests ... We've now covered 96% of all code. Everything else is not testable for us at this point.	2024-10-24 12:25:13 +02:00
Winni Neessen	1399a3331a	Refactor and extend client email tests ... Refactor existing email sending tests by organizing multiple edge cases and adding robust test coverage. This includes adding checks for invalid sender/recipient addresses, handling DSN support, and ensuring proper client server interactions during failures like DATA init, DATA close, and MAIL FROM.	2024-10-24 12:03:56 +02:00
Winni Neessen	45ebcb95b3	Remove redundant connection check in send function. ... The connection check is performed in the c.Reset call just before the c.checkconn call, making this redundant. Removing it simplifies the code and eliminates unnecessary error handling for connection status. This change helps improve code maintainability.	2024-10-24 12:02:57 +02:00
Winni Neessen	1519522e5d	Reduce sleep duration in client tests ... Decreased sleep time from 300ms to 30ms across multiple tests to improve test execution speed.
