Python, Selenium und die Webdriver

Immer wieder kommt aber die Frage auf: „Wo muss der geckodriver oder die Webdriver liegen?“

Einfache Antwort “ Vollkommen egal wohin ihr ihn legt! “

Woher bekommt man die Treiber?

Integration des Chrome Drivers in Python

import time
from selenium import webdriver

driver = webdriver.Chrome('/path/to/chromedriver')  # Optional argument, if not specified will search path.
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
search_box = driver.find_element_by_name('q')
search_box.send_keys('ChromeDriver')
search_box.submit()
time.sleep(5) # Let the user actually see something!
driver.quit()

Weitere Informationen zu diesem Thema findet man hier: http://chromedriver.chromium.org/getting-started

import time

from selenium import webdriver
import selenium.webdriver.chrome.service as service

service = service.Service('/path/to/chromedriver')
service.start()
capabilities = {'chrome.binary': '/path/to/custom/chrome'}
driver = webdriver.Remote(service.service_url, capabilities)
driver.get('http://www.google.com/xhtml');
time.sleep(5) # Let the user actually see something!
driver.quit()

Woher bekomme ich weitere Treiber:

Für Opera bekommt ihr bei github einen passenden Treiber. Wie ihr diesen

Opera: https://github.com/operasoftware/operachromiumdriver

Wie man den Opera Webdriver im Android Bereich einbindet könnt ihr hier in diesem Beispiel einsehen:

Opera und die android.py

import time

from selenium import webdriver
from selenium.webdriver.chrome import service


webdriver_service = service.Service('path/to/operadriver')
webdriver_service.start()

android_caps = {}
android_caps['operaOptions'] = {
    'androidPackage': 'com.opera.browser',
}

driver = webdriver.Remote(webdriver_service.service_url, desired_capabilities=android_caps) #Android

driver.get('https://www.google.com/')
input_txt = driver.find_element_by_name('q')
input_txt.send_keys('operadriver\n')

time.sleep(5) #see the result
driver.quit()

Wie man den Opera Driver in Appium einbindet könnt ihr hier sehen:

appium

desired_caps['appPackage'] = 'com.opera.browser'
desired_caps['androidDeviceSocket'] = desired_caps['appPackage'] + '.devtools'

    flick = TouchActions(driver).flick_element(pager, -1000, 0, 70);
    flick.perform();

def get_element_id(el_id):
    if desired_caps['automationName'].lower() == 'android':
        el_id = "com.opera.android.browser:id/" + el_id

Wohin installieren?

Grundsätzlich kann man die Treiber dahin legen wohin man will. Wir binden diese entsprechend über Python ein, somit auf den Ordner und das File einzeln.

Wie binde ich den Treiber in den Source ein?

Chrome

from selenium import webdriver
url="C:\\Programs\\Python36\\BrowersDriver\\chromedriver.exe"
driver=webdriver.Chrome(url)
driver.get("http://www.yahoo.com")
driver.close()
driver.quit()
