常规断言

•  比较大小
• price= self.driver.find_element(By.XPATH,'//*[contains(@resource-id="current_price")]'.text
• assert float(price) >=100

•  包含
• name= self.driver.find_element(By.XPATH,'//*[contains(@resource-id="stockName")]'.text
• assert "xx" in name

•  布尔值验证
• def check
　　   name= self.driver.find_element(By.XPATH,'//*[contains(@resource-id="current_price")]'
• if len(name)=0:
• 　　return True
• else:
• 　　return False
• assert check()

Hamcrest断言

• 安装　　pip install pyhamcrest
• 导入　　from hamcrest import *

 

• 对象比较：
• assert_that("this is" equal_to("this is"))

 

• 数值对比是否接近
• assert_that(1,close_to(0.5,0.5)

 

• 包含某个字符
• assert_that('abc’，contains_string('d'))

 

• 任意顺序包含
• assert_that("matches"，contains_inanyorder(*"hamcrest")
