When we use Selenium, it's not convenient to use WebDriverWait with its cluttered chain actions. Instead of many imports and instances (By, WebDriverWait, expected_conditions) you can use fast and robust actions.

Package's source code is made available under the MIT License

Quick Start

You can use actions, by the following way.

from selenium.webdriver.chrome.webdriver import WebDriver
from croco_selenium import click
driver = WebDriver()
click(driver, 10, '//input[@type="submit"]')

If you don't want to pass driver every using of actions, you can create an instance of ActionPerformer

from selenium.webdriver.chrome.webdriver import WebDriver
from croco_selenium import ActionPerformer
driver = WebDriver()
action_performer = ActionPerformer(driver)
timeout = 10

action_performer.send_keys(timeout, '//input[@type="password"]', 'password')
action_performer.click(timeout, '//input[@type="submit"]')

One of the best ways to use actions is create an instance of ChromeDriver and perform actions by calling methods on it. That class derived from ActionPerformer and ChromiumDriver

import os
from croco_selenium import ChromeDriver, Proxy
proxy = Proxy(host='123.89.46.72', port=8000, username='croco', password='webDriver')
project_dir = os.path.dirname(os.path.abspath(__file__))
extension_paths = [os.path.join(project_dir, 'extensions/metamask.crx')]

driver = ChromeDriver(proxy=proxy, extension_paths=extension_paths)
driver.get('https://facebook.com')
driver.send_keys(15, '//input[@id="email"]', '[e-mail]')

Actions Overview

You can perform the following actions, using croco-selenium:

• add_cookies
• click
• close_tabs
• get_element
• get_elements
• get_element_attribute
• get_element_text
• send_keys
• silent_send_keys
• switch_to_another_window
• switch_to_frame
• switch_to_parent_frame
• wait_for_invisibility
• wait_for_windows

And there are 3 useful decorators:

• handle_pop_up
• handle_in_new_tab
• handle_new_tab

Actions

add_cookies

Adds cookies to a current page. It takes valid string containing json, list of cookies or one cookie as dictionary.

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

cookies = '{"domain":".facebook.com","expirationDate":1689249734,"httpOnly":true,"name":"c_user","path":"/","secure":true,"value":"100083466604886"}'
driver.get('facebook.com')
driver.add_cookies(cookies)

click

Clicks on element in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()
driver.click(timeout, '//input[@type="submit"]')

close_tabs

Closes all tabs in browser. It's convenient to use, when you add extensions to your browser and their windows occur with starting a driver.

import os
from croco_selenium import ChromeDriver

project_dir = os.path.dirname(os.path.abspath(__file__))
extension_paths = [os.path.join(project_dir, 'extensions/metamask.crx')]

driver = ChromeDriver(extension_paths=extension_paths)
driver.close_tabs()
driver.get('https://facebook.com')
driver.send_keys(15, '//input[@id="email"]', '[e-mail]')

get_element

Returns an element in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

element = driver.get_element(timeout, '//input[@type="submit"]')
element.click()

get_elements

Returns an elements in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

elements = driver.get_elements(timeout, '//input')

for element in elements:
    element.click()

get_element_attribute

Returns an element's attribute in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

assert driver.get_element_attribute(timeout, '//input[@type="checkbox"]', 'checked')

get_element_text

Returns element's text in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

print(driver.get_element_text(timeout, '//h1'))

send_keys

Sends keys in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.send_keys(timeout, '//input[@type="password"]', 'password')
driver.click(timeout, '//input[@type="submit"]')

silent_send_keys

Sends keys with delay between characters in browser. It's convenient to use when you would like to hide your bot activity

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.silent_send_keys(timeout, '//input[@type="password"]', 'password')
driver.click(timeout, '//input[@type="submit"]')

switch_to_another_window

Switches to a different window from current window in browser. It's convenient to use, when you have two windows to be handled

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.silent_send_keys(timeout, '//input[@type="password"]', 'password')
driver.click(timeout, '//input[@type="submit"]')
driver.switch_to_another_window(timeout)

driver.click(timeout, '//input[@type="submit"]')
driver.switch_to_another_window(timeout)

switch_to_frame

Switches to the frame

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.switch_to_frame(timeout, '//iframe[@data-hcaptcha-widget-id]')
driver.click(timeout, '//input[@type="submit"]')

switch_to_parent_frame

Switches to the parent frame

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.switch_to_frame(timeout, '//iframe[@data-hcaptcha-widget-id]')
driver.click(timeout, '//input[@type="submit"]')
driver.switch_to_parent_frame()

wait_for_invisibility

Wait for element's invisibility in browser

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.click(timeout, '//button')
driver.wait_for_invisibility(timeout, '//*[@id="popup"]')

wait_for_windows

Wait for occurring of number of windows

from croco_selenium import ChromeDriver

timeout = 10
driver = ChromeDriver()

driver.wait_for_windows(timeout, 2)

Decorators

handle_pop_up

Switches to another window, performs decorated function and switches back. Pop up has to be closed after performing decorated function.

This decorator is usually used for browser extensions' pop-ups. Example of function performing a third-party Metamask connection:

from croco_selenium import ChromeDriver, handle_pop_up
from selenium.common import TimeoutException

@handle_pop_up()
def connect(driver: ChromeDriver, password: str) -> None:
    try:
        password_xpath = '//*[@id="password"]'
        driver.send_keys(7, password_xpath, password)

        unlock_xpath = '//button[@data-testid="unlock-submit"]'
        driver.click(5, unlock_xpath)
    except TimeoutException:
        pass

    for _ in range(3):
        next_xpath = '//button[@data-testid="page-container-footer-next"]'
        driver.click(10, next_xpath, ignored_exceptions=TimeoutException)

handle_in_new_tab

Opens new tab, performs decorated function, closes new tab and switches back. Here is example of function performing getting of 2FA code from browser extension.

from croco_selenium import ChromeDriver, handle_in_new_tab

@handle_in_new_tab()
def get_code(driver: ChromeDriver, account) -> str:
    timeout = 15

    driver.get('<EXTENSION_URL>')

    code_field_xpath = '//*[contains(@class, "code")]'
    code_fields = driver.get_elements(timeout, code_field_xpath)

    code_field = code_fields[account.id]

    code = code_field.text
    return code

handle_new_tab

Performs decorated function in new tab and switches back. New tab has to be opened during performing decorated function.
