I'm trying out phantomJS with webdriver and I'm having trouble with handling javascript alerts. I notice the phantomjs driver desired_capabilities has a field 'handlesAlerts': False Is there a way to set this value to true? I've tried the obvious way but that doesn't have any effect:
drv = webdriver.PhantomJS(desired_capabilities={'handlesAlerts': True})
print drv.desired_capabilities
{u'browserName': u'phantomjs',
u'driverName': u'ghostdriver',
u'driverVersion': u'1.0.3',
u'handlesAlerts': False,
u'javascriptEnabled': True,...}
I can change the value in the dictionary drv.desired_capabilities['handlesAlerts'] = True, but when I try to switch to an alert, I get an error message.
$cat index.html
<html>
<body>
<script type="text/javascript">
alert('FOO!');
</script>
Hello World.
</body>
</html>
>>> from selenium import webdriver
>>> driver = webdriver.PhantomJS()
>>> driver.desired_capabilities['handlesAlerts'] = True
>>> driver.get('index.html')
>>> alert = driver.switch_to_alert()
>>> alert.text
