python+selenium网页自动化测试

元素等待：

显示等待

WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, "myDynamicElement"))
    )

隐式等待

driver.implicitly_wait(10) # seconds

查找元素方式：

• ind_element_by_id

• find_element_by_name

• find_element_by_xpath

• find_element_by_link_text

• find_element_by_partial_link_text

• find_element_by_tag_name

• find_element_by_class_name

• find_element_by_css_selector

直接看BasePage的实现：

from selenium.webdriver import ActionChains
from selenium.webdriver.support import expected_conditions as ec
from selenium.webdriver.support.wait import WebDriverWait
​
from client.WebClient import WebClient

​
class BasePage(object):
    def __init__(self):
        self.driver = WebClient().get_driver()
        self.config_util = ConfigUtil()
        self.wait = WebDriverWait(self.driver, 10)
​
    def find_element(self, *loc):
        # 需要进行转义，没有转义不可以进行
        try:
            by = loc[0][0]
            locator = loc[0][1]
            loc = (by, locator)
            WebDriverWait(self.driver, 50).until(ec.visibility_of_element_located(loc))
        except Exception:
            print ("No such element found " + str(locator))
        else:
            return self.driver.find_element(*loc)
​
    def find_elements(self, *loc):
        try:
            by = loc[0][0]
            locator = loc[0][1]
            loc = (by, locator)
            print loc
            for i in loc:
                print i
            WebDriverWait(self.driver, 50).until(ec.visibility_of_element_located(loc))  # 需要找到元素，并且该元素也可见
        except Exception:
            raise ValueError("No such element found " + str(locator))
        return self.driver.find_elements(*loc)
​
    def is_element_exists(self, *loc):
        try:
            by = loc[0][0]

            loc = (by, locator)
            WebDriverWait(self.driver, 50).until(ec.presence_of_element_located(loc))  # 只关心元素是否存在在页面中
            return self.driver.find_element(loc).text()
        except:
            return False
​
    # 执行操作js代码
    def execute_js(self, script):
        self.driver.execute_script(script)
        time.sleep(2)
​
    # 鼠标悬停
    def execute_mouse_hover(self, *loc):
        mouse = self.find_element(*loc)
        ActionChains(self.driver).move_to_element(mouse).perform()
​
    # 用于等待元素可用（元素肯定会出现，只是时间问题）
    def wait_element_is_enabled(self, timeout, *loc):
        self.driver.implicitly_wait(timeout)
        try:
            self.driver.find_element(*loc).is_enabled()
        except:
            pass
        self.driver.implicitly_wait(8)
