app自动化7-数据驱动

1. 参数化：根据传入的数据，对测试用例进行迭代调用

2. 数据驱动：基于数据完成流程调度，通过数据来自外部数据文件

3. 参数化是数据驱动的基础和特例

4. 参数化：通过pytest实现参数化

from appium import webdriver
from hamcrest import  *
import pytest

class TestDemo():
    def setup(self):
        #参数设置
        caps = {}
        caps["platformName"] = "android"
        caps["deviceName"] = "qiucaixia"
        caps["appPackage"] = "com.xueqiu.android"
        caps["appActivity"] = ".view.WelcomeActivityAlias"
        caps["autoGrantPermissions"] = "true"   #自动赋予app权限

        self.driver = webdriver.Remote("http://localhost:4723/wd/hub", caps)
        self.driver.implicitly_wait(10)  #隐式等待

    @pytest.mark.parametrize("keyword,expected_price",[
        ("pdd",20),
        ("alibaba",200),
        ("jd",30)
    ])
    def test_search(self,keyword,expected_price):
        #点击搜索栏
        self.driver.find_element_by_id("com.xueqiu.android:id/home_search").click()
        #输入搜索内容
        self.driver.find_element_by_id("com.xueqiu.android:id/search_input_text").send_keys(keyword)
        self.driver.find_element_by_id("name").click()
        price=self.driver.find_element_by_id("current_price")
        assert float(price.text) > expected_price
        #断言属性- resource-id
        assert 'price' in price.get_attribute('resource-id')

        #hamcrest断言
        assert_that(price.get_attribute('package'),equal_to('com.xueqiu.android'))

    def teardown(self):
        self.driver.quit()

5. 数据驱动：

    1> 参数化数据读取自外部文件：使用YAML，JSON读取

    2> 测试步骤读取自外部文件：定制执行引擎

    3> 断言步骤读取自部文件：定制执行引擎

    4> 整个用例读取自外部文件：动态创建用例

6. 参数化数据读取YAML文件：

    1> yaml文件的数据：（search_data.yaml）

- ['pdd',20]
- [jd,10]
- [alibaba,100]

    2>  脚本如下：(脚本和yaml文件在一个目录下)

from appium import webdriver
from selenium.webdriver.support.ui import WebDriverWait  # 显示等待
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.common.by import By
from hamcrest import  *
import pytest
import yaml

class TestDemo():
    with open(r'D:\test_dir\pycharm_project\other\search_data.yaml','r') as f:
        search_data=yaml.safe_load(f)
    print(search_data)
    def setup(self):
        #参数设置
        caps = {}
        caps["platformName"] = "android"
        caps["deviceName"] = "qiucaixia"
        caps["appPackage"] = "com.xueqiu.android"
        caps["appActivity"] = ".view.WelcomeActivityAlias"
        caps["autoGrantPermissions"] = "true"   #自动赋予app权限
        # caps["unicodeKeyboard"]="true"  #支持输入中文

        self.driver = webdriver.Remote("http://localhost:4723/wd/hub", caps)
        self.driver.implicitly_wait(10)  #隐式等待

    @pytest.mark.parametrize("keyword,expected_price",search_data)
    def test_search_from_yaml(self,keyword,expected_price):
        #点击搜索栏
        self.driver.find_element_by_id("com.xueqiu.android:id/home_search").click()
        #等待搜索栏下面的页面展示出来，否则会覆盖掉输入内容后搜索出来的结果，导致下面选择不到结果
        WebDriverWait(self.driver,15).until(expected_conditions.visibility_of_element_located((By.ID,'tv_hot_title')))
        #输入搜索内容
        self.driver.find_element_by_id("com.xueqiu.android:id/search_input_text").send_keys(keyword)
        #等待搜索结果可见
        WebDriverWait(self.driver,15).until(expected_conditions.visibility_of_element_located((By.ID,'name')))
        self.driver.find_element_by_id("name").click() #点击搜索到的第一个内容
        price=self.driver.find_element_by_id("current_price")
        assert float(price.text) > expected_price
        #断言属性- resource-id
        # assert 'price' in price.get_attribute('resource-id')

        #hamcrest断言
        # assert_that(price.get_attribute('package'),equal_to('com.xueqiu.android'))
        # assert_that(price.get_attribute('id'),equal_to('current_price'))

    def teardown(self):
        self.driver.quit()

7. 测试步骤数据驱动：将步骤和数据都维护到yaml文件中

8. 步骤数据驱动举例：

    1> 步骤和用例数据维护在step_data.yaml文件

- id: home_search
- wait: tv_hot_title
- id: search_input_text
  input: pdd
- wait: name
- id: name
- id: current_price

 2> 用例脚本：(脚本和yaml文件在一个目录下)

        caps = {}
        caps["platformName"] = "android"
        caps["deviceName"] = "qiucaixia"
        caps["appPackage"] = "com.xueqiu.android"
        caps["appActivity"] = ".view.WelcomeActivityAlias"
        caps["autoGrantPermissions"] = "true"   #自动赋予app权限

        self.driver = webdriver.Remote("http://localhost:4723/wd/hub", caps)
        self.driver.implicitly_wait(10)  #隐式等待

    def test_search_from_steps(self):
        TestCase(r'D:\test_dir\pycharm_project\other\steps_data.yaml').run(self.driver)

    def teardown(self):
        self.driver.quit()

class TestCase:
    def __init__(self,path):
        file=open(path,'r')
        self.steps=yaml.safe_load(file)

    def run(self, driver :webdriver):
        for step in self.steps:
            element=None
            print("#######",step)
            if isinstance(step,dict):
                if 'id' in step.keys():
                    element=driver.find_element_by_id(step['id'])
                elif 'xpath' in step.keys():
                    element=driver.find_element_by_xpath(step['xpath'])
                else:
                    print(step.keys())

                if 'input' in step.keys():
                    element.send_keys(step['input'])
                elif 'get' in step.keys():
                    attr_value=element.get_attribute(step['get'])
                elif 'math' in step.keys():
                    activty_value=element.text
                elif 'wait' in step.keys():
                    WebDriverWait(driver,15).until(expected_conditions.visibility_of_element_located((By.ID,step['wait'])))
                else:
                    element.click()

                if 'assert' in step.keys():
                    expected_value=step['assert']
                    assert activty_value>expected_value
