pytest参数化
当一组测试用例有固定的测试数据时，就可以通过参数化的方式简化测试用例的编写。
通过pytest.mark.parametrize()方法设置参数：
参数名："user,pw,expected"用来定义参数的名称
参数值：通过数组定义参数值时，每一个元组都是一条测试用例的测试数据
ids参数：默认None，用来重新定义测试用例的名称
"""

@pytest.mark.parametrize(
    "user,pw,expected",
    [("xuzhu666", "123456", "xuzhu666，欢迎来到"),
     ("zz666", "123456", "zz666，欢迎来到")],
    ids=["case1","case2"])
def test_login(user,pw,expected):
    driver = webdriver.Chrome()
    driver.get("http://39.98.138.157/shopxo/")
    driver.find_element_by_link_text("登录").click()
    driver.find_element_by_xpath("/html/body/div[4]/div/div[2]/div[2]/form/div[1]/input").send_keys(user)
    driver.find_element_by_xpath('/html/body/div[4]/div/div[2]/div[2]/form/div[2]/input').send_keys(pw)
    driver.find_element_by_xpath("/html/body/div[4]/div/div[2]/div[2]/form/div[3]/button").click()
    sleep(3)
    # == 测试相等
    # 登录成功检查
    welcome = driver.find_element_by_xpath("//*[contains(text(),'欢迎来到')]").text
