So I am trying to open websites on new tabs inside my WebDriver. I want to do this because opening a new WebDriver for each website takes about 3.5secs using PhantomJS, I want more speed...

I'm using a multiprocess python script, and I want to get some elements from each page, so the workflow is like this:

Open Browser

Loop through my array

For element in array -> Open website in new tab -> do my business -> close it

But I can't find any way to achieve this.

Here's the code I'm using. It takes forever between websites, I need it to be fast... Other tools are allowed, but I don't know too many tools for scrapping website content that loads with JavaScript (divs created when some event is triggered on load etc) That's why I need Selenium... BeautifulSoup can't be used for some of my pages.

#!/usr/bin/env python

import multiprocessing, time, pika, json, traceback, logging, sys, os, itertools, urllib, urllib2, cStringIO, mysql.connector, shutil, hashlib, socket, urllib2, re

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

from PIL import Image

from os import listdir

from os.path import isfile, join

from bs4 import BeautifulSoup

from pprint import pprint

def getPhantomData(parameters):

    try:

        # We create WebDriver

        browser = webdriver.Firefox()

        # Navigate to URL

        browser.get(parameters['target_url'])

        # Find all links by Selector

        links = browser.find_elements_by_css_selector(parameters['selector'])

        result = []

        for link in links:

            # Extract link attribute and append to our list

            result.append(link.get_attribute(parameters['attribute']))

        browser.close()

        browser.quit()

        return json.dumps({'data': result})

    except Exception, err:

        browser.close()

        browser.quit()

        print err

def callback(ch, method, properties, body):

    parameters = json.loads(body)

    message = getPhantomData(parameters)

    if message['data']:

        ch.basic_ack(delivery_tag=method.delivery_tag)

    else:

        ch.basic_reject(delivery_tag=method.delivery_tag, requeue=True)

def consume():

    credentials = pika.PlainCredentials('invitado', 'invitado')

    rabbit = pika.ConnectionParameters('localhost',5672,'/',credentials)

    connection = pika.BlockingConnection(rabbit)

    channel = connection.channel()

    # Conectamos al canal

    channel.queue_declare(queue='com.stuff.images', durable=True)

    channel.basic_consume(callback,queue='com.stuff.images')

    print ' [*] Waiting for messages. To exit press CTRL^C'

    try:

        channel.start_consuming()

    except KeyboardInterrupt:

        pass

workers = 5

pool = multiprocessing.Pool(processes=workers)

for i in xrange(0, workers):

    pool.apply_async(consume)

try:

    while True:

        continue

except KeyboardInterrupt:

    print ' [*] Exiting...'

    pool.terminate()

    pool.join()

You can achieve the opening/closing of a tab by the combination of keys COMMAND + T or COMMAND + W (OSX), whereas on other Operating Systems CONTROL + T / CONTROL + W would work.

In selenium, you can emulate such behaviour. You will need to create one webdriver and as many tabs as the tests you need.

from selenium import webdriver

from selenium.webdriver.common.keys import Keys

 

driver = webdriver.Firefox()

driver.get("http://www.google.com/")

 

#open tab

driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 't') 

# You can use (Keys.CONTROL + 't') on other OSs

 

# Load a page 

driver.get('http://stackoverflow.com/')

# Make the tests...

 

# close the tab

# (Keys.CONTROL + 'w') on other OSs.

driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 'w') 

 driver.close()
