== Tabs

I use the following tabs during the development:

1) bitlbee-skype:

vim, make, etc.

2) bitlbee:

gdb --args ./bitlbee -v -n -D
run

3) skyped:

python skyped.py -n -d

4) irssi


== Tests

The plugin is tested with a mocked IRC client and a mocked skyped.

=== Requirements

Python pexpect module is required to run the tests.

To run tests with bitlbee built in a development tree and not (the one)
installed in the system (e.g. /usr), make sure to specify --plugindir= option to
./configure script during the build process:

bitlbee% ./configure --skype=1 --plugindir="$(realpath .)"

Otherwise bitlbee will try to load skype.so (among other things) from /usr/lib,
which is probably not what you want to test, or produce "Unknown protocol"
error.

=== Running

Tests can be run by running test.py script in this ("protocols/skype")
directory.

For more control over how/which tests are being run from there, use "python -m
unittest" command:

bitlbee/protocols/skype% python -m unittest test
bitlbee/protocols/skype% python -m unittest -f test
bitlbee/protocols/skype% python -m unittest test.Test.testMsg

If bitlbee crashes during tests with SIGSEGV (segmentation fault), it's likely
that there is some problem with skype.c plugin.
To get a backtrace of such crash, use:

bitlbee/protocols/skype% ATTACH_GDB=true python -m unittest test.Test.testMsg

Example shows running "testMsg" test with gdb attached to bitlbee, which will
produce full backtrace in "t/gdb-<pid>.log" files (see pid in pexpect error
output of the test).

=== Adding new tests

To add a new test, the following steps are necessary:

1) Add a new -skyped.mock file: just do the test manually, copy&paste the
skyped output and clean it up, so Alice talks to Bob.  You can test the created
mock file by starting skyped with the -m option, and testing it from an IRC
client manually.

2) Add a new -bitlbee.mock file: do the test manually from irssi, and use:

/connect -rawlog rawlog localhost

Then clean up the rawlog: the input lines are parsed as matching patterns, so
boring prefix/suffix text can be left out, non-interesting lines can be
deleted. The output lines still have to be strict IRC commands, as usual.

3) Add the new test to test.py and run it!
