用Selenium模拟键盘空格、删除等操作

模拟键盘按键操作的方法：
1.win32api
2.SendKeys
3.WebElement对象的send_keys()方法
4.ActionChains类提供了几个模拟按键的方法

以ActionChains为例演示输入文本、输入空格、删除：

from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys

class TestActionChains():
    def setup(self):
        self.driver = webdriver.Chrome()
        # 隐式等待
        self.driver.implicitly_wait(5)
        self.driver.get('https://sahitest.com/demo/label.htm')

    def teardown(self):
        self.driver.quit()
def test_keys(self):
    self.driver.find_element(By.XPATH, '/html/body/label[1]/input').click()
    action = ActionChains(self.driver)
    # 输入username
    action.send_keys("username").pause(1)
    # 输入空格
    action.send_keys(Keys.SPACE).pause(1)
    # 输入zz
    action.send_keys('zz').pause(1)
    # 键盘删除
    action.send_keys(Keys.BACK_SPACE).perform()
    sleep(5)
