Chapter3 Working with Elements

3.1 Automating textboxes, text areas, and buttons

3.1.1 Clearing text from textbox and text-area elements

works only on a textbox and text area

area.clear()

3.1.2 Entering text in textbox and text-area elements

can be used on any element that accepts values by typing on the element

area.send_keys("Selenium testing tools cook book")

we can also simulate pressing non-text keys using the send_keys() method by using Keys

area.send_keys("123" + webdriver.common.keys.Keys.TAB)

list of Keys: https://selenium.dev/selenium/docs/api/py/webdriver/selenium.webdriver.common.keys.html

3.1.3 Submitting forms

area.submit()

3.1.4 Performing a click on a button element

button.click()

Clicking on an invisible element will result in a ElementNotVisibleException exception

3.2 Checking an element's text

button = driver.find_element_by_id("web-nav-app-download-btn").find_element_by_tag_name("span")
print(button.text)

3.3 Checking an element's attribute and CSS values

button.get_attribute("class")

button.value_of_css_property("width")

3.4 Automating dropdowns and lists

remember

from selenium.webdriver.support.select import Select

at the head place

lang = driver.find_element_by_tag_name("select")
# returns a list of all options belonging to this select tag
print(len(Select(lang).options))
Select(lang).select_by_visible_text("JavaScript")
Select(lang).select_by_value("JavaScript")
Select(lang).select_by_index(0)

3.5 Checking options in the Select element

remember to import unittest because of assert method

import unittest

lang = driver.find_element_by_tag_name("select")

expectedOptions=['html','css','JavaScript','php']
actualOptions = []
for option in Select(lang).options:
    actualOptions.append(option.text)

print(actualOptions)
print(expectedOptions)
tc = unittest.TestCase()
tc.assertListEqual(actualOptions,expectedOptions)

3.6 Checking selected options in dropdowns and lists

Select(lang).select_by_visible_text("html")
Select(lang).select_by_visible_text("css")
Select(lang).select_by_visible_text("JavaScript")
Select(lang).select_by_visible_text("php")
Select(lang).deselect_by_visible_text("php")

It seems that only one option is selected. When I select "css", "html" is deselected
only multi-select box will support selecting more than 1 option...

3.7 Automating radio buttons and radio groups

tc = unittest.TestCase()
apple = driver.find_element_by_xpath("//input[@value='apple']")
print(apple.get_attribute("value"))

if not apple.is_selected():
    apple.click()
tc.assertTrue(apple.is_selected())

fruits = driver.find_elements_by_tag_name("input")
print(len(fruits))
for fruit in fruits:
    print(fruit.get_attribute("value"))

3.8 Automating checkboxes

tc = unittest.TestCase()
fruits = driver.find_elements_by_tag_name("input")

for fruit in fruits:
    if not fruit.is_selected():
        fruit.click()
    tc.assertTrue(fruit.is_selected())
    print(fruit.get_attribute("value"))

print(len(fruits))

3.9 Working with WebTables

rows = driver.find_elements_by_tag_name("tr")
print(len(rows))

for row in rows:
    cols = row.find_elements_by_tag_name("td")
    print(len(cols))
    for col in cols:
        print(col.text + "\t")
