Developer Test Environment¶
This assumes you have your basic server running and you’ve made some changes and you want to test them to work out what’s going right... or wrong.
Cassandane is a Perl-based integration test suite for Cyrus. Cassandane documentation includes information on setting up tests and writing new tests.
Why “Cassandane”? Wikipedia indicates that Cassandane was the name of the consort of King Cyrus the Great of Persia, founder of the Achaemenid Persian Empire. So that’s kinda cool.
Install and configure Cassandane¶
You already have it – it’s in the “cassandane” subdirectory of the cyrus-imapd sources.
sudo apt-get install libanyevent-perl libtest-unit-perl libconfig-inifiles-perl \ libdatetime-perl libbsd-resource-perl libxml-generator-perl \ libencode-imaputf7-perl libio-stringy-perl libnews-nntpclient-perl \ libfile-chdir-perl libfile-libmagic-perl libnet-server-perl libunix-syslog-perl \ libdata-uuid-perl libjson-xs-perl libdata-ical-perl libjson-perl \ libdatetime-format-ical-perl libtext-levenshteinxs-perl \ libmime-types-perl libdatetime-format-iso8601-perl libcal-dav-perl \ libclone-perl libstring-crc32-perl libnet-ldap-server-perl
The quickest option for the rest is installing via CPAN, but you could build packages using dh-make-perl if that is preferred.
sudo cpan -i Tie::DataUUID sudo cpan -i XML::Spice sudo cpan -i XML::Fast sudo cpan -i Data::ICal::TimeZone sudo cpan -i Text::VCardFast sudo cpan -i Mail::IMAPTalk sudo cpan -i List::Pairwise sudo cpan -i Convert::Base64 sudo cpan -i Net::DAVTalk sudo cpan -i Net::CardDAVTalk sudo cpan -i Net::CalDAVTalk sudo cpan -i Math::Int64
cd /path/to/cyrus-imapd/cassandane make
cassandane.iniin your home directory
cassandane.inito set up your cassandane environment.
Assuming you configure cyrus with
--prefix=/usr/cyrus(as above), then the defaults are mostly fine
[valgrind]if you’re using it.
[imaptest]section. For the moment, it may be necessary to suppress the binary tests as they are buggy upstream still.
[imaptest] basedir=/path/to/imaptest/imaptest suppress=append-binary urlauth-binary fetch-binary-mime fetch-binary-mime-qp
Ensure that the following config items are off:
altnamespace = no unixhierarchysep = no
cyrususer and matching group and also add
sudo adduser --system --group cyrus sudo adduser cyrus mail
Give your user account access to sudo as

sudo -u cyrus mkdir /var/tmp/cass
IMAPTest is a testing suite which uses libraries from the Dovecot installation.
Fetch and compile Dovecot.
- Get the latest nightly snapshot from http://dovecot.org/nightly/dovecot-latest.tar.gz
./configure && make(No need for make install)
Fetch and compile IMAPTest
- Download http://dovecot.org/nightly/imaptest/imaptest-latest.tar.gz
./configure --with-dovecot=../dovecot-2.2 && make(No need for make install)
--with-dovecot=<path>parameter is used to specify path to Dovecot v2.2 sources’ root directory.
Rebuild Cyrus for Testing¶
Prepare to rebuild by making the source tree shiny and clean as if you’ve done a brand new checkout. Leave no old artifacts lying around!
cd /path/to/cyrus-imapd make clean git clean -f -x -d autoreconf -v -i
Apply caution! The
git clean removes anything that’s a build product, but also anything it doesn’t know about: which may include your new source files you haven’t added yet.
Set the compile flags for testing and debugging. It may be of use to also add
--std=gnu99 here. That does TONS of warnings, and
-g enables debug mode.
CFLAGS="-g -fPIC -W -Wall -Wextra -Werror"
Configure the environment.
./configure --prefix=/usr/cyrus --with-cyrus-prefix=/usr/cyrus \ --enable-autocreate --enable-http --enable-unit-tests \ --enable-replication --enable-nntp --enable-murder \ --enable-idled --enable-xapian --enable-calalarmd \ --enable-backup make lex-fix # you need this if compile fails with errors from sieve/sieve.c
And finally, make it.
If you’re testing across versions, the binsymlinks is necessary as older Cyrus doesn’t have the binaries in the new locations. This uses the default install path of
/usr/cyrus/. It can be useful to also have
/usr/cyrus24, etc, if you’re testing with older versions as well.
make -j16 && make -j16 check sudo make install sudo make install-binsymlinks sudo cp tools/mkimap /usr/cyrus/bin/mkimap
Running the tests¶
cyrus, run the tests.
cd /path/to/cyrus-imapd/cassandane sudo -u cyrus ./testrunner.pl -f pretty -j 8
Debugging and stacktraces¶
Check out the guide to running Cyrus components under gdb.
In the event of a crash, here’s how to generate a stacktrace.
Tips and Tricks¶
Read the script to see other options. If you’re having problems, add more
-v options to the testrunner to get more info out.
Looking for memory leaks? Run with –valgrind to use valgrind (if it’s installed). It is slower, which is why it doesn’t need to be always used.
Running with -v -v is very noisy, but gives a lot more data. For example: all IMAP telemetry.
Also helpful to run
sudo tail -f /var/log/syslog, and examine /var/tmp/cass as root to examine log files and disk structures for failed tests.
