Added basic yii support for codeception - #115

@DavertMik so i added new class(plugins/frameworks/yii/CodeceptionHttpRequest) that must be used in codeception to avoid headers sent, it also handle cookies. I've tested on yii fresh created app, that was created through console by running yiic webapp and i've tested on currently developing application with db, cache, etc..., connector and module works correctly. But i have some trobles with codeception itself when it cant see selector like this button[type="submit"] or it sometimes cant see text when i call $I->see(), but page renders correctly. You can test it too on some yii web app, or create new with this guide http://www.yiiframework.com/doc/guide/1.1/en/quickstart.first-app and run the cept that i've wrote in the module Yii docs, this cept:

$I = new TestGuy($scenario);
$I->wantTo('Test index page');
$I->amOnPage('/index.php');
$I->see('My Web Application','#header #logo');
$I->click('Login');
$I->see('Login','h1');
$I->see('Username');
$I->fillField('#LoginForm_username','demo');
$I->fillField('#LoginForm_password','demo');
$I->click('#login-form input[type="submit"]');
$I->seeLink('Logout (demo)');
$I->click('Logout (demo)');
$I->seeLink('Login');

But dont forget to add in protected/config/main.php in components array:

'request' => array(
    'class'=>'CodeceptionHttpRequest',
),

and put this file (from plugins/frameworks/yii/CodeceptionHttpRequest) to components folder under protected, so it will be auto-imported when app starts.

@DavertMik did u test/check it?)

sorry, not yet. Didn't have time last days. Well, let's merge and find out )
Thanks for this commit. Great job!

I have:

<?php
return CMap::mergeArray(
    require(dirname(__FILE__).'/main.php'),
    array(
        'components'=>array(
            'fixture'=>array(
                'class'=>'system.test.CDbFixtureManager',
            ),
            'db'=>array(
                'connectionString'=>'sqlite:'.dirname(__FILE__).'/../data/blog-test.db',
            ),
        'request' => array(
            'class'=> CODECEPTION_LIB_ROOT.'/plugins/frameworks/yii/web/CodeceptionHttpRequest',
        ),

I get:

Cannot redeclare class CodeceptionHttpRequest

:(

No, i mean put CodeceptionHttpRequest under the yii application components, because Yii autoloader wil not found file in the codeception directory (
So request will be:

        'request' => array(
            'class'=> 'CodeceptionHttpRequest',
        ),

where CodeceptionHttpRequest is a file that located under yourapp/protected/components
I will do some more research on how maybe add out-of-the-box support for it, will try to provide PR in few days, but for now as i said, all you need to do is just copy it on your components folder of your app )

@Ragazzo I installed codeception in my Yii Application (Phundament) via composer and I am able to use it out of the box, at least without CodeceptionHttpRequest - but I've only tried acceptance tests so far, so maybe I am missing something?!

See this document about Installing Phundament and this one about adding codeception and here are my (combined) Cepts for Phundament.

Let me know, if you want to elaborate this.

Well, CodeceptionHttpRequest is only needed in functional tests where all tests are proceed in the codeception internals (without curl just symfony browser-kit), so Yii1 module purpose is to use it in codeceptionfunctional (they are much faster then acceptance) and unit tests, for acceptance tests you dont need it. Need to notice that in last days there were important fix for the unit testing with codeception and Yii, so if u want to use latest snapshot you need to use codeception source, or add plugins\frameworks\yii1 directory in phar complier file lists (so the Yii1 module in codeception will auto-import CodeceptionHttpRequest and other things like CTestCase, CDbTestCase). We've discussed this (adding this folder in the phar file lists) with @DavertMik here #198 (comment).

Thank you so far, I think I need to take a closer look at it.

Ok) feel free to create new issues on codeception repo about some Yii module improvements, bugs, etc. any help or suggestions are really appreciated :)

So I've a question ... my app still creates the default tests from the Yii Web App Skeleton into tests/.
But when I run codeception bootstrap then its tests also get generated into the same directory.

But AFAIK codeception can at least do the same things for you, like Yii's default test suite, but in a much more convenient way.

Would you recommend to replace Yii's default test suite completely with codeception or would it lack some features?

Well, afaik you can place codeception tests anywhere u want (need to check bootstrap config switchers), but as for me i got this structure in protected folder:

tests
    codeception
        codeception.yml \\here generated by codeception files and other
        fixtures \\fixtures for codeception
    functional  \\standard yii tests files and folders goes below
    unit
     ....

For now i prefer classic phpunit tests in Yii, thats why i use unit folder in standard yii tests folder, i use codeception more for acceptance and functional tests, but you can also use it for unit-tests too, it can handle them out-of-the-box (u can also generate them with generate:phpunit command). As for me this all just "a matter of taste"

I think ... I'll do it the same way, that sounds good, thank you!

Just for the record, I did the following:

vendor/bin/codecept bootstrap tests/codeception

I've also updated our wiki page.
