Sample Tests

Functional Testing

Simple imaptest to cover the basics:

timeout 10s imaptest pass=supersecret host=127.0.0.1 mbox=testmbox.sm40k user=testuser1 Fetch2=100 store=100 delete=100 expunge=100 clients=1

Check the output for errors.

Verify that messages exist in INBOX:

doveadm mailbox status -u testuser1 all INBOX

Copy a message with doveadm:

doveadm copy -u testuser1 Trash mailbox INBOX 1

Copy messages with imaptest:

imaptest pass=supersecret host=127.0.0.1 mbox=testmbox.sm40k user=testuser1 copybox=Trash

Move a message:

doveadm move -u testuser1 Trash mailbox INBOX 1

Performance Testing:

Test rapid delivery of lots of messages via IMAP APPEND (100k test users)

imaptest - user=testuser%d pass=testpass mbox=testmbox append=100,0 logout=0 users=100000 clients=500 msgs=100000 no_pipelining secs=10

Test rapid delivery of lots of messages via LMTP (Useful for Scality CDMI, where an LMTP request takes 2 PUTs and IMAP APPEND takes 3 PUTs)

imaptest profile=imaptest.profile mbox=testmbox secs=10

imaptest.profile:

lmtp_port = 24
lmtp_max_parallel_count = 500 # Set to ~50-60% of total_user_count
total_user_count = 800
rampup_time = 0s

  username_format = testuser%n
  count = 100%

Load Testing:

1h mixed test against proxy (10.41.1.135) with 2m users and 200 clients:

timeout 1h imaptest pass=testpassword host=10.41.1.135 mbox=testmbox user=testuser%d users=1-2000000 Fetch2=100 store=100 delete=90 expunge=100 clients=200

8hr mixed test with 2m users; generally this would be run against multiple proxies (host=proxy ip) from multiple imaptest nodes.

timeout 8h imaptest pass=testpassword host=127.0.0.1 mbox=testmbox user=testuser%d users=1-2000000 Fetch2=100 store=100 delete=90 expunge=100 clients=100

POP3 + LMTP test with profile

To generate read load (BODY FETCHs):

imaptest - user=terra.29.%d select=100 fetch2=100,0 logout=0 clients=10 msgs=100000 no_pipelining users=400 no_tracking

To avoid out-of-socket issues when connecting to local HAproxy instance, spread load between multiple local IP addresses to hit HAproxy, e.g.:

obox_fs = scality:http://127.0.%4Hu.1:8080/?timeout_msecs=30000&addhdr=X-Dovecot-Hash:%2Mu/%2.3Mu&bulk_delete=1
