Codeception with testing base

Hello all.

I have a fortnight (very big) problem. And don’t understand what am I doing wrong.

www/tests/codeception/frontend/codeception.yml




namespace: tests\codeception\frontend

actor: Tester

paths:

    tests: .

    log: _output

    data: _data

    helpers: _support

settings:

    bootstrap: _bootstrap.php

    suite_class: \PHPUnit_Framework_TestSuite

    colors: true

    memory_limit: 1024M

    log: true

config:

    # the entry script URL (with host info) for functional and acceptance tests

    # PLEASE ADJUST IT TO THE ACTUAL ENTRY SCRIPT URL


    test_entry_url: mysite.com


modules:

    config:

        Db:

            dsn: 'mysql:host=localhost;dbname=mydb.yii2_tests'

            user: 'root'

            password: 'passw'

            cleanup: true




www/tests/codeception/config/config.php




<?php

/**

 * Application configuration shared by all applications and test types

return [

    'language' => 'en-US',

    'controllerMap' => [

        'fixture' => [

            'class' => 'yii\faker\FixtureController',

            'fixtureDataPath' => '@tests/codeception/common/fixtures/data',

            'templatePath' => '@tests/codeception/common/templates/fixtures',

            'namespace' => 'tests\codeception\common\fixtures',

        ],

    ],

'components' => [

        'db' => [

            'dsn' => 'mysql:host=localhost;dbname=mydb.yii2_tests',

            'username' => 'root',

            'password' => 'passw',

        ],

        'mailer' => [

            'useFileTransport' => true,

        ],

        'urlManager' => [

            'enablePrettyUrl' => true,

            'showScriptName' => false,

        ],

    ],

];



www/tests/codeception/frontend/acceptance.suite.yml




class_name: AcceptanceTester

modules:

    enabled:

        - WebDriver

        - tests\codeception\common\_support\FixtureHelper

        - Db


    config:

        WebDriver:

            url: mysite.yii2

            browser: firefox




During testing codeception insert data in my main DB (not mydb.yii2_tests). Why?

What i need to do?
