POST - Read Timeout error - II

Executed the script on the app in non-SSL mode (HTTP and not HTTPS), and the script executes without issue. So looks like issue is due to the fact that the page is a secure page...hmm.

POST - Read Timeout error

I have been getting this exception all too often lately, and I am not sure if the root cause is due to the site under test being a HTTPS, or is it due to other 'caching' reasons.

At some points, the scripts continue to execute even after this exception, but most of the time, it just freezes and then after the timeout period testComplete[, ] is executed.

Line of script that causes this exception is -

"
...
$sel->click_ok("btnAddToCart");
$sel->wait_for_page_to_load_ok("10000");
$sel->click_ok("finishButton");
$sel->wait_for_page_to_load_ok("10000");
$sel->select_window_ok();
$sel->click_ok("document.caPurchasingAssistantWizardForm.submitbutton[1]");
$sel->wait_for_page_to_load_ok("10000");
$sel->click_ok("//input[\@value='Apply Discount...']");
...
"

Gracefully exiting on a validation error on page

There are often times when there is a validation error on the page and the buttons expected oinideal scenario dont appear. In such cases, the script continues to execute though - expecting the elements in future lines of the script to be present, when they are actually not since the application has stopped due to the Validation error.

At times, this causes an issue too, coz the script ends up 'clicking' an element that it should not have (for eg. a submit button that should have been clicked upon the scenario being successful will still get clicked even though the expected result wasnt encountered - leading to different flow being executed).

So to avoid such things from happening, I wrote up a simple subroutine that I added at the start of the script which would "get_body_text()" and then verify that a text 'validation error' was not present anywhere on the page. If found, exit. No more steps to be executed.

##########################
sub data_extract
{
my $text=0;
$text = $sel->get_body_text();
if ($text =~ m/$_[0]/){
print "there is a validation error on page\n";
$sel->select_frame_ok("topframe");
$sel->click_ok("link=Logout");
$sel->stop;
exit;
}
}

Purpose of this Blog

Not going to spend too much time nor too many lines explaining the purpose!
I am creating this to document issues / resolutions / tricks / processes that I have used to go about using Perl, lest I forget about them in future.
I should have started this last year itself, but better late than never! I will try to recall and add older info from time to time.
