Adds the file api/bots_api/provision.py that installs dependencies
for bots using pip. This file is also used by run.py when running
a bot. However, for testing, you need to separately provision the bots.
This involves both using the new `initialize`
method for calling `get_config_info`, and
refactoring the testing framework by adding a
way for mocking this method.
This commit decouples the http mock conversation
feature from assert_bot_response(), and moves it
to the context manager mock_http_conversation().
This allows a modular design with context managers
that could be added for assert_bot_response().
This commit integrates the mock_test function in
check_expected_responses and makes this function usable
for simple tests only by not allowing mock http conversations.
assert_bot_response() is now used for single message-response pairs,
resolving potential issues with multiple messages and a single http
request-response pair.
The giphy bot test file is updated accordingly.
'followup' bot has different message handling behavior for
different messages.
For usual messages it calls 'send_message' function of
'BotHandlerApi' class.
For empty messages it calls 'send_reply' function of
'BotHandlerApi' class.
Since few bots directly call 'send_message' function of
'BotHandlerApi' class instead of calling 'send_reply' function
first, add 'mock_test_send_message' to check for 'send_message'
function.
All test_<bot>.py files now need to specify which function the bot
will be sending the response to, for each particular message.
Make 'test_virtual_fs.py' and 'test_thesaurus.py' test files
consistent with other bots.
The regex used for parsing .crypt-table didn't allow colons in class
names. This commit changes the [^:] token with \S, meaning that class
names can now contain colons but can no longer contain whitespace.
I think this should be fine, since zcrypt is only used for MIT zephyr,
where (by convention) class names do not contain whitespace.
Additionally, it should not be possible for us to accidentally consume a
field-separating colon as part of the class capture group because the
regex enforces that all field-separating colons are followed by one or
more whitespace characters, whereas the class name cannot contain
whitespace.
