codeception does not see dump.sql

I'm using Yii2 with Codeception. The problem is that Codeception seems to not see the database dump. For simplicity, I consider only LoginCept acceptance tests: ``` use tests\_pages\LoginPage; $I = new WebGuy($scenario); $I->wantTo('ensure that login works'); $loginPage = LoginPage::openBy($I); $I->see('Login', 'h1'); $I->amGoingTo('try to login with empty credentials'); $loginPage->login('', ''); $I->expectTo('see validations errors'); $I->see('Username cannot be blank.'); $I->see('Password cannot be blank.'); ... ``` So, when I run ``` ./vendor/bin/codecept run tests/acceptance/LoginCept.php ``` everything runs without errors: ``` Acceptance Tests (1) ---------------------------------------- Trying to ensure that login works (LoginCept.php) Ok ------------------------------------------------------------- ``` But as soon as I add the following line ``` echo $I->grabFromDatabase('user', 'name', ['id' => 1]); ``` the test starts to fail: ``` Acceptance Tests (1) ---------------------------------------- Trying to ensure that login works (LoginCept.php) Error ------------------------------------------------------------- Time: 2.11 seconds, Memory: 9.75Mb There was 1 error: --------- 1) Failed to ensure that login works in LoginCept.php #1 F:\site\tests\acceptance\LoginCept.php:8 <-- 8 is the number of added line #2 F:\site\tests\acceptance\LoginCept.php:8 FAILURES! ``` Below I put the detailed info from config files. codeception.yml file has the following content: ``` paths: tests: tests log: tests/_log data: tests/_data helpers: tests/_helpers settings: bootstrap: _bootstrap.php suite_class: \PHPUnit_Framework_TestSuite memory_limit: 1024M log: true colors: true modules: enabled: [Db] config: Db: dsn: 'mysql:host=localhost;dbname=site_test' user: 'daemon' password: 'HsqyJSAbZC3q3KJa' dump: 'tests/_data/dump.sql' populate: true cleanup: true ``` The print out of \Yii::$app->db gives: ``` yii\db\Connection Object ( [dsn] => mysql:host=localhost;dbname=site_test [username] => daemon [password] => HsqyJSAbZC3q3KJa [attributes] => [pdo] => [enableSchemaCache] => [schemaCacheDuration] => 3600 ... ) ``` With the credentials above, I can log in manually to my database (in phpmyadmin). The database dump is located in `F:\site\tests\_data\dump.sql`. I've created it from my working database called site and made some modification inside it: ``` CREATE DATABASE IF NOT EXISTS `site_test` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin; USE `site_test`; DROP TABLE IF EXISTS `user`; CREATE TABLE `user` ( `id` smallint(5), `name` varchar(50) ); INSERT INTO `user` VALUES (1,'admin'); ``` Codeception build command everytime I run it, gives: ``` $ ./vendor/bin/codecept build Building Guy classes for suites: acceptance, functional, unit WebGuy includes modules: WebHelper, PhpBrowser WebGuy.php generated successfully. 48 methods added TestGuy includes modules: Filesystem, TestHelper, Yii2 TestGuy.php generated successfully. 53 methods added CodeGuy includes modules: CodeHelper CodeGuy.php generated successfully. 1 methods added ```
