OBSOLETE ^

Test::AskAnExpert is the successor module, the name is better and there have been some compatability breaking changes. You don't want this.

NAME ^

Test::Smart - Test things that require Human Intelligence automatically. (By asking someone)

SYNOPSIS ^

  use Test::Smart import => [qw(ask answer)],tests => 7;

Start up the Human Interface:

  initialize("Test::Smart::Interface::Subclass",'Subclass args'...);

Synchronously submit and wait for a yes or a no answer:

  get_yes("Question");
  get_no("Question");

Same, but with timeouts: (In seconds)

  get_yes("Need a fast asnwer",10);
  get_no("Need a fast denial",10);

Submit an asynchronous question:

  $question = ask("This could take a while");

Check the answer:

  answer($question,'yes');
  answer($question,'no');

The check can timeout too:

  answer($question,'yes',10);

DESCRIPTION ^

Test::Smart aims to fill a hole in the current set of testing tools by integrating an automated method for asking testing questions that computers cannot easily answer like: "Is this meteorologically sound?" or "Does this output fit into category x?" or "Is this distrobution quality?" and still allow standard test tools to work properly in terms of generating reports, locking the doors if the tests aren't passing, etc. etc.

Test::Smart is built on Test::Builder and will play nice with Test::Simple, Test::More, and anything they play nice with. To provide Smart answers to conceptual questions we cheat by asking people instead of actually solving a Very Hard Problem regarding machine intelligence. This requires a little more overhead as we need to set up a way to talk to people, and provide them some (but not too much) time to tender an answer.

initialize($interface_name, @interface_params)

The initialize function must be called before using any of Test::Smart's functions to load a Human Interface, otherwise the default (skip when sent a query) will load. To specify something other than the default pass a subclass of Test::Smart::Interface. @InterfaceParameters are any Interface specific parameters, consult the documentation of the Interface you're using for what (if anything) to pass here.

On error it returns false, allowing you to try multipule Interfaces in a short- circuit style before giving up:

  initialize("Test::Smart::Telepathy")
    or initialize("Test::Smart::AskLarry",say_please=>1)
    or skip_all("No good interfaces available");

Note that skip_all isn't required, if no Interface is specified Test::Smart will use a default Interface that simply skips if its asked to test anything.

get_yes/get_no ($question, $name, [$Timeout])

Test::Smart provides two methods for the programmers who don't want to muck with asynchronous interaction, get_yes and get_no. get_yes passes when the question asked is answered yes, get_no the opposite. They are slim wrappers arround ask and answer, taking a plain text question, test name, and optionally a timeout in the same way.

ask($question_text, $test_name)

NOTE: This does not actually run any tests!

ask is a very self explanatory function: it sends a question to be answered by whatever is on the other side of the Interface (Test::Smart::Pass anyone?). It returns a Test::Smart::Question object which is later used for retrieving the answer. Since this is the factory for Test::Smart::Question objects it also optionally takes the test name the question is bound to, though this can be changed with the name method. If there was an error in asking the question the object will have its skip parameters set so when answer is called on it the test will be skipped. Read the Test::Smart::Question documentation if you'd like to query the object your self and do something other than skip the test (like re-initialize to a different Interface and ask again, or BAIL_OUT).

$QuestionText should be plaintext with no markup, the Interface is expected to format it nicely for the human on the other side (e.g. if its an HTML interface give them nice links) to make their life a little easier.

answer($question_obj, $expected, [$timeout])

answer takes a previously asked question and waits until an answer is ready or optionally $Timeout seconds have passed and then executes typical test magic.

$QuestionObj should be a Test::Smart::Question object returned by ask or correctly constructed otherwise. $Expected can be any capitalization of yes or no and will be checked against the answer in the question for the test.

EXPORTS ^

By default get_yes and get_no are exported, to get ask and answer pass import => [qw(ask answer)] to the use line.

BUGS ^

This is the first version, it probably has some. Bug reports, failing tests, and patches are all welcome.

TODO ^

Timeouts. I haven't done them yet, but they'll be in the next release. I promise.

Test::Smart::Interface::CGI and Test::Smart::Interface::DBI. These would probably be more useful than the current File interface which exists more to prove it can be done than anything.

SUPPORT ^
