Feature: IMAP fetch header of message
Background: Fetch header deterministic content type and boundary
Given there is connected user "user"
And there are messages in mailbox "INBOX" for "user"
| id | from | to | subject | n attachments | content type | body |
| 1 | f@m.co | t@pm.me | A message with attachment | 2 | html | body |
| 2 | f@m.co | t@pm.me | A simple html message | 0 | html | body |
| 3 | f@m.co | t@pm.me | A simple plain message | 0 | plain | body |
# | 4 | f@m.co | t@pm.me | An externally encrypted message | 0 | mixed | body |
# | 5 | f@m.co | t@pm.me | A simple plain message in latin1 | 0 | plain-latin1 | body |
And there is IMAP client logged in as "user"
And there is IMAP client selected in "INBOX"
@ignore-live
Scenario Outline: Fetch header deterministic content type and boundary
Given header is not cached for message "<id>" in "INBOX" for "user"
# First time need to download and cache
When IMAP client fetches header of "<id>"
Then IMAP response is "OK"
And IMAP response contains "Content-Type: <contentType>"
And IMAP response contains "<parameter>"
And header is cached for message "<id>" in "INBOX" for "user"
# Second time it's taken from imap cache
When IMAP client fetches body "<id>"
Then IMAP response is "OK"
And IMAP response contains "Content-Type: <contentType>"
And IMAP response contains "<parameter>"
# Third time header taken from DB
When IMAP client fetches header of "<id>"
Then IMAP response is "OK"
And IMAP response contains "Content-Type: <contentType>"
And IMAP response contains "<parameter>"
Examples:
| id | contentType | parameter |
| 1 | multipart/mixed | boundary=4e07408562bedb8b60ce05c1decfe3ad16b72230967de01f640b7e4729b49fce |
