Why am I unable to catch the Unexpected Alert Exception? - php

Question

I am using a try catch block to catch an exception and I am unable to catch it as it still says:
In Exception.php line 155:
unexpected alert open: {Alert text : The form is not complete and has not been submitted yet. There is 1 problem with your submission.}
(Session info: chrome=73.0.3683.75)
(Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 4.15.0-38-generic x86_64)
My feature file:
<?php
use Behat\Behat\Hook\Scope\AfterStepScope;
use Behat\Behat\Tester\Exception\PendingException;
use Behat\Behat\Context\Context;
use Behat\MinkExtension\Context\MinkContext;
use WebDriver\Exception\UnexpectedAlertOpen;
/**
* Defines application features from the specific context.
*/
class FeatureContext extends MinkContext implements Context
{
/**
* Initializes context.
*
* Every scenario gets its own context instance.
* You can also pass arbitrary arguments to the
* context constructor through behat.yml.
*/
public function __construct()
{
}
/**
* #Given I fill in the email field with :email
*/
public function iFillInTheEmailFieldWith($email)
{
dump($email);
$this->visit('/471w2222');
$page = $this->getSession()->getPage();
$page->find('xpath', '//*[#id="tfa_1111"]')->setValue($email);
}
/**
* #When I submit the form
*/
public function iSubmitTheForm()
{
try {
$page = $this->getSession()->getPage();
$page->find('xpath', '//*[#id="submit_button"]')->click();
}
catch (UnexpectedAlertOpen $e){
dd($e->getMessage());
$this->getSession()->getDriver()->getWebDriverSession()->accept_alert();
}
}
}
The alert shows up :
$page->find('xpath', '//*[#id="submit_button"]')->click();
executes. But it is unable to catch it. Why?

As per the error message...
(Session info: chrome=73.0.3683.75)
(Driver info: chromedriver=2.41.578700 (2f1ed5f9343c13f73144538f15c00b370eda6706),platform=Linux 4.15.0-38-generic x86_64)
...the main issue is the incompatibility between the version of the binaries you are using as follows:
You are using chromedriver=2.41
Release Notes of chromedriver=2.41 clearly mentions the following :
Supports Chrome v67-69
You are using chrome=73.0
Release Notes of ChromeDriver v2.46 clearly mentions the following :
Supports Chrome v71-73
So there is a clear mismatch between the ChromeDriver v2.41 and the Chrome Browser v73.0
Solution
Upgrade ChromeDriver to current ChromeDriver v2.46 level.
Keep Chrome version between Chrome v73 levels. (as per ChromeDriver v2.45 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
