Currently, I use a robot framework-ImapLibrary for open mail to check context mail, then I have a function to click "Don't Send email", So How to check mail in the mailbox that actually I don't recieve an email.
Thanks for your help in advance!
You can use these keywords to check if email is not sent after executing "Don't send email" function.
Run Keyword And Expect Error Some Error Wait For Email sender=noreply@domain.com folder=INBOX subject=Some Subject
P.S. Replace "Some Error" with error what is returned from Wait For Email
keyword. Make sure you have Open Mailbox
before using above keyword.
