How can i use external class in Codeception?

问题

i created an external class called StringHelper and i putted the require into the _bootstrap.php.

I used it into my acceptance test and it didn't work:

<?php
class StringHelper {
    public static function getString($length) {
        return "Hello World";
    }
}

_bootstrap.php

require_once 'components/StringHelper.php';

My LoginCest.php

<?php
use \AcceptanceTester;

class LoginCest
{
    public function test01(AcceptanceTester $I)
    {
        $I->wantTo('Try to access without permission');
        $I->amOnPage('#/list'); 
        $I->waitForText('You don`t have permission.', 10, '.alert');
    }

    public function test02(AcceptanceTester $I)
    {
        $I->wantTo(StringHelper::getString(2));
        SeleniumHelper::fillField($I, '#desc_login', StringHelper::getString(2));
        $I->click("#btn-enter");
        $I->waitForText('Please, fill the login field', 10, '.alert'); 
    }
}

My returned message:

Acceptance Tests (2) --------------------------------------------
Trying to Try to access without permission (LoginCest::test01) Ok
Trying to test02 (LoginCest::test02)                           Ok

Here in "Trying to test02" why doesn't appear "Hello World"?

回答1:

Try to write a module/helper for this function as codeception queues the commands, so when your command is executed codeception is not "listening".
