Advanced features of selenium webdriver

Keyboard and mouse events

adopt WebDriver Of ActionChains Class implementation .

Keyboard events

adopt ActionChains class , Analog simultaneous press shift+n key .

ActionChains(driver).\
　　key_down(Keys.SHIFT).\
　　send_keys('n').\
　　key_up(Keys.SHIFT).perform()

Mouse events

move_to_element() You can move the cursor from the current position to the specified position .

age_field = driver.find_element_by_id("age")
ActionChains(self.driver).move_to_element(age_field).perform()

Double click operation

double_click Method implementation double click .

box = driver.find_element_by_tag_name("div")
ActionChains(driver).double_click(box).perform()

Mouse drag

adopt drag_and_drop() Implement the drag and drop operation of the mouse .

source = driver.find_element_by_id("draggable")
target = driver.find_element_by_id("droppable")
ActionChains(self.driver).drag_and_drop(source,
target). perform()

call JavaScript

WebDriver Class contains the following methods ：

Screen capture

When the test script cannot find “promo_banner” Element time , The program calls save_screenshot() Method to automatically capture the screen , And save the image file name defined by us in the specified path .

try:
　　promo_banner_elem = driver.find_element_by_id("prom
o_banner")
　　self.assertEqual("Promotions", promo_banner_elem.te
xt)
except NoSuchElementException:
　　st = datetime.datetime.fromtimestamp(time.time()).
strftime('%Y%m%d_%H%M%S')
　　file_name = "main_page_missing_banner" + st + ".png
"
　　driver.save_screenshot(file__name)
　　raise

Screen Recording

Webdriver Class does not integrate screen recording api Method . So you need to use python Medium Castro library .
Castro Is based on cross platform screen recording tools Pyvnc2swf Development , Use VNC The protocol records the screen and generates SWF file .
adopt Castro, It can also realize screen recording of remote machines .

pip install Castro

from castro import Castro
class SearchProductsTest(unittest.TestCase):
	def setUp(self):
		self.screenCapture = Castro(filename="testSearchByCategory. swf")
		self.screenCapture.start() #  Start recording 
		#  establish webdriver session, Capture page element coordinates 
		...

	def teardown(self):
		self.driver.quit()
		self.screenCapture.stop() #  Exit recording 
		

Frame handling

switch_to.window() Method to get the name or handle information of the pop-up window , Switch to the pop-up frame to be operated .

def setUp(self):
	self.driver = webdriver.Firefox()
　　self.driver.get(self.URL)
　　self.driver.maximize_window()
　　
def test_popup_window(self):
	driver=self.driver
	parent_window_id = driver.current_window_handle
	driver.switch_to.window("HelpWindow") 
　　driver.close()  #  Close subwindow 
　　driver.switch_to.window(parent_window_id)  #  Return to parent window 

operation cookies

WebDriver Provides reading 、 Add and remove cookies Methods .

def test_store_cookie(self):
	store_cookie = driver.get_cookie("store")
　　self.assertEqual(None, store_cookie)
　　select_language.select_by_visible_text("French")
　　store_cookie = driver.get_cookie("store")['value'] #  By passing cookie Get the corresponding name cookie Value 
　　self.assertEqual("french", store_cookie)
