Is you application template recent or created using older Yii version?

[DavertMik]

Looks like you have conflicts between different Codeception versions.
If you look at Codeception/Module/Yii2 there is nothing like resetPersistentVars() on line 195.
So you are using older Codeception version there. Please check you don't keep older Codeception globally installed or somewhere else.

[githubjeka]

codecept in global C:\codecept... last master version.

{
    "minimum-stability" : "stable",
    "require": {
        "codeception/base": "^2.2.3",       
        "codeception/verify": "~0.3.1",
        "facebook/webdriver": "^1.0.1",
        "codeception/specify": "*"      
    }
}

I also could not run the test yesterday.

[viv7i]

it is recently created application template, i changed codeception/base to codeception/codeception in composer.json file then run tests

[viv7i]

if there is conflict between codeception versions then how can i remove it globally and install fresh full version of it

[Naktibalda]

@DavertMik https://github.com/Codeception/Codeception/blob/2.2.6/src/Codeception/Module/Yii2.php#L195

I can't imagine how $this->client could be unset in _after.

[sidgwick]

just adjust your browser setting in acceptance.suite.yml, I solved this problem by change the default browser from firefox to chrome.

class_name: AcceptanceTester
modules:
    enabled:
        - WebDriver:
            url: http://localhost:8080
            browser: chrome
        - Yii2:
            part: init
