Codeception seeInDatabase() not working as expected - codeception

Question

I have problems getting codeceptions seeInDatabase() to work. This is my Cest:
public function testContactMailCheckbox(AcceptanceTester $I) {
$I->scrollTo("#adminMailSettingsForm", 0, -200);
$I->seeInDatabase("pib_users", [
"user_email" => "admin-cest#example.org",
"user_receive_contact_notification" => 0
]);
$I->click("//label[#for='contactMailNotification']", "#adminMailSettingsForm");
$I->waitForJS("return $.active == 0;",10);
$I->wait(100);
$I->seeInDatabase("pib_users", [
"user_email" => "admin-cest#example.org",
"user_receive_contact_notification" => 1
]);
}
The first seeInDatabase() passes, everything is fine. I can verify that this seeInDatabase-Assertion works correctly, by changing the default-data in my database dump. When I change the default data to "user_receive_contact_notification" => 1, the first seeInDatabase fails, which means it is working correctly.
I use $I->wait(100) to verify, that there are no synchronisation-issues. During this timespan I can check via phpMyAdmin, that the row was indeed updated correctly. That means the test should pass.
Here is my Db-config:
actor: AcceptanceTester
modules:
enabled:
- WebDriver:
url: 'http://pib.local/'
window_size: false # disabled in ChromeDriver
port: 5555
browser: chrome
capabilities:
chromeOptions:
args: ["--headless", "--no-sandbox", "--disable-gpu", "--window-size=1920,1080"]
- \Helper\Acceptance
- Sequence
- \Helper\DbHelper
config:
\Helper\DbHelper:
user: "root"
password: ""
dsn: "mysql:host=localhost;dbname=pib"
cleanup: true
dump: 'tests/database_dump_tests.sql'
populate: true
reconnect: true
step_decorators: ~
My DbHelper contains only a single function:
class DbHelper extends \Codeception\Module\Db
{
public function putInDatabase($table, $data, $insertOnlyIfNotExisting = true) {
// if ignoreDuplicateError is true, only execute insert when not existing already
if($this->countInDatabase($table, $data) == 0 | !$insertOnlyIfNotExisting) {
$this->_insertInDatabase($table, $data);
}
}
}
This might be related to this question. I don't use Laravel though, so just using the seeRecord()-helper isn't going to help me.
