selenium用例编写

小白入门：http://selenium-python.readthedocs.io/

from selenium import webdriver
from selenium.webdriver.common.by import By
from time import sleep
class TestBaidu:
    def setup(self):
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()
        # 隐式等待 类似于异步
        self.driver.implicitly_wait(5)
    def teardown(self):
        # 退出所有标签
        self.driver.quit()
    def test_baidu(self):
        self.driver.get('http://www.baidu.com')
        self.driver.find_element(by=By.ID,value='kw').send_keys('爱玛科技')
        self.driver.find_element(by=By.ID,value='su').click()
        self.driver.find_element(by=By.LINK_TEXT,value='爱玛科技[603529]A股实时行情 - 百度股市通').click()

selenium三种等待方式

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.support.wait import WebDriverWait


class Test_wait:
    def setup(self):
        self.driver = webdriver.Chrome()
        self.driver.maximize_window()
        self.driver.get('https://www.jd.com/?cu=true&utm_source=baidu-pinzhuan&utm_medium=cpc&utm_campaign=t_288551095_baidupinzhuan&utm_term=0f3d30c8dba7459bb52f2eb5eba8ac7d_0_579fb540a49b4b5fbb41cb802ab375c1')

    def test_wait(self):
        self.driver.find_element(by=By.LINK_TEXT, value='京东家电').click()

        # 一点要穿一个参数进去 无论有没有使用
        # def wait(x):
        #     return len(self.driver.find_element(by=By.CLASS_NAME, value='lc-imgarea-base__links-item')) >= 4
        # WebDriverWait(self.driver,8).until(wait)

        WebDriverWait(self.driver,6).until(expected_conditions.element_to_be_clickable([By.CSS_SELECTOR,'.logo']))
        self.driver.find_element(by=By.LINK_TEXT, value='企业购').click()

web控件定位与常见操作

selenium点击与输入

Xpath

Css Selector

web控件的交互进阶

ActionChains

表单操作

网页frame与多窗口处理

from selenium_base import Base
from selenium.webdriver import ActionChains
from time import sleep

class Test_switch(Base):
    def test_switch(self):
        self.driver.get('http://www.baidu.com')

from selenium_base import Base
class Test_Switch(Base):
    def test_switch(self):
        self.driver.get('https://www.runoob.com/try/try.php?filename=jqueryui-api-droppable')

selenium 多浏览器处理

但是呢 要在terminal输入：browser=Chrome pytest selenium_test/switch_to_frame.py -s -v

执行javascript脚本

from selenium_base import Base
class Test_Js(Base):
    def test_js(self):
        self.driver.get('http://www.baidu.com')
        self.driver.execute_script("document.querySelector('#kw').value='selenium测试'")
        self.driver.execute_script("document.querySelector('#su').click()")
        self.driver.execute_script("document.documentElement.scrollTop=10000")
        self.sleep(2)
        self.driver.execute_script("document.querySelectorAll('.page-inner_2jZi2 a')[8].click()")
        self.sleep(5)
        for code in [
            'return document.title','return JSON.stringify(performance.timing)'

Page Object设计模式

• 公共方法要替代页面的服务
• 不要暴露页面的细节
• 不要在page object中使用断言（assert）
• 方法返回page object
• 不需要表示整个页面
• 同一动作的不同结果被合并为不同的方法
  

等待

无界面模式

不会打开网页，但是一样能获取到数据。
