[wtr-general] Re: Cant capture alert using "alert" method of Page Object
Thanks a lot Justin in taking time to write a detailed explanation about
the issue. Novice automation engineers like me are very blessed to have
people like you and Titus showing patience to explain basic things to us.
You are right about the issue. Though Im not able to confirm with the devs
regarding the JS that runs between the click and the alert as you suggested
the #alert function was able to capture the alert with a sleep after the
click.
I will user the Watir alert method as its has automatic waiting.
As far as I know there is only a limited no of times alert is even shown
our our application.
Cheers
Navi

[wtr-general] Re: Cant capture alert using "alert" method of Page Object
Hi Navi,
At this point, I would say there is a design flaw in Page-Object's #alert
method, which does:
if @browser.alert.exists?
value = @browser.alert.text
@browser.alert.ok
end
The conditional check is likely the cause of your problem. I don't know the
history of how we got here, but my guess is that we wanted to handle
controls that randomly created alerts.
Unfortunately, this can be easily thrown off. I assume your div does not
immediately trigger the alert. There is probably some sort of processing
and/or asynchronous call that happens before deciding to show the alert.
This can be enough to cause problems - ie:
# Div is clicked
# Some JavaScript starts to determine if the alert should appear
# #alert checks if an alert exists or not, finds nothing so just moves on
(ie no alert to dismiss)
# The JavaScript finishes processing, displaying the alert
# The next Watir command fails since the alert is still there
You can see how little is required to create the timing issue. The
following page has a div, that when clicked waits 10ms before displaying
the alert.
function sleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
async function run() {
await sleep(10); // (in milliseconds) slight delay before alert is
triggered
alert("test");
}
asdf
The following page-object clicks this div but does not dismiss the alert.
The exception then occurs on the next command:
class MyPage
include PageObject
def do_stuff
alert do
div.click
end
sleep(1) # ensure alert has appeared
p div.text
#=> Selenium::WebDriver::Error::UnhandledAlertError
end
end
page = MyPage.new(browser)
page.do_stuff
I would be curious if you added a #sleep to your code if that would address
the problem:
@browser.div(:class => 'address-details', :index =>0).click
alert_text = alert do
@browser.div(:class => 'select-checkbox', :index =>1).click
sleep(10) # add this sleep to ensure that the alert appears before
proceeding
end
sleep(10)
puts alert_text
Though if that solves your problem, I do not think the #alert method is
adding any value. You know the alert is going to appear, so you may as well
call Watir's alert code (ie Titus' example), which would include automatic
waiting.

[wtr-general] Re: Cant capture alert using "alert" method of Page Object
Hi Titus
@browser.div(:class => 'address-details', :index =>0).click
# alert_text = alert do
# @browser.div(:class => 'select-checkbox', :index =>1).click
# end
# sleep 10
# puts alert_text
@browser.div(:class => 'select-checkbox', :index =>1).click
puts @browser.alert.text
@browser.alert.ok
This worked.
But I would like to know why the PageObject method alert is not working as
expected.
May be wait for Justin :-)
