本文以开源 bilibili 客户端为例，编写了三个测试用例供参考
开源 bilibili 客户端链接：https://github.com/HotBitmapGG/bilibili-android-client

用例一：模拟登录

#coding:utf-8
from appium import webdriver
from time import sleep

capabilities = {}
capabilities['platformName'] = 'Android'
capabilities['platformVersion'] = '5.0'
capabilities['deviceName'] = 'Honor'
capabilities['appPackage'] = 'tv.danmaku.bili'
capabilities['appActivity'] = 'tv.danmaku.bili.ui.splash.SplashActivity'

dr = webdriver.Remote('http://localhost:4723/wd/hub', capabilities)
sleep(3)

# 以下模拟用户登录（）

#dr.find_element_by_xpath("//*[@text='未登录']").click()
dr.find_element_by_xpath("//*[contains(@text,'未登录')]").click()

#dr.find_element_by_id("tv.danmaku.bili:id/user_nick_text").click() # 如果使用@text，点击不到按键，所以此处使用id
dr.find_element_by_id("user_nick_text").click() # 如果使用@text，点击不到按键，所以此处使用id

dr.find_element_by_xpath("//*[contains(@text,'你的手机号')]").send_keys("1111111")
dr.tap([(580, 826),])
dr.tap([(72,1225),(391,1263)])
#dr.find_element_by_xpath("//*[contains(@text,'登录')]").click() # 该语句无法点击“登录”按钮

dr.tap([(778,972),]) #通过坐标点击“登录”

注：由于密码框 NAF(non-accessiblity friendly) 属性为 true，无法直接通过 Appium 既有方法定位到，故只能通过确定的坐标定位（坐标可以通过开发者选项中的 “打开指针位置” 得到），然后继续通过坐标点击键盘按键模拟用户输入

用例二：逐一点击侧滑目录的各目录项

#coding:utf-8
import unittest
from appium import webdriver
from time import sleep

class bilibiliTests(unittest.TestCase):

    def setUp(self):
        desired_caps = {}
        desired_caps['platformName'] = 'Android'
        desired_caps['platformVersion'] = '5.0'
        desired_caps['deviceName'] = 'Samsung'
        desired_caps['appPackage'] = 'tv.danmaku.bili'
        desired_caps['appActivity'] = 'tv.danmaku.bili.ui.splash.SplashActivity'

        self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
        sleep(5)

    #tearDown 方法做清理工作
    def tearDown(self):
        self.driver.close_app()
        self.driver.quit()

    def test_directory(self): #测试侧滑菜单
        self.driver.find_element_by_xpath("//*[@text='未登录']").click()
        # driver.find_element_by_id("tv.danmaku.bili:id/design_menu_item_text").click()
        els = self.driver.find_elements_by_id("tv.danmaku.bili:id/design_menu_item_text") #侧滑菜单各个子项

        for el in els:
            el.click()
            self.driver.back()
            print self.driver.current_activity.__str__();
            if(self.driver.current_activity.__str__()!='.MainActivityV2'):
                self.driver.back()
            self.assertEqual(self.driver.current_activity.__str__(), '.MainActivityV2')
            sleep(1)
            self.driver.find_element_by_xpath("//*[@text='未登录']").click()


#开始测试类中以test开头的测试用例，方法一
suite = unittest.TestLoader().loadTestsFromTestCase(bilibiliTests)
unittest.TextTestRunner(verbosity=2).run(suite)

#方法二
#if __name__ == '__main__':
#   unittest.main()

注：该用例使用 Python unittest 单元测试框架

用例三：搜索

# coding:utf-8
import os
import unittest
from time import sleep

from appium import webdriver

PATH = lambda p: os.path.abspath(
    os.path.join(os.path.dirname(__file__), p)
)

class TestBilibiliInput(unittest.TestCase):
    def setUp(self):
        capabilities={}
        capabilities['platformName'] = 'Android'
        capabilities['platformVersion'] = '5.0'
        capabilities['deviceName'] = 'SAMSUNG'
        capabilities['appPackage'] = 'tv.danmaku.bili'
        capabilities['appActivity'] = 'tv.danmaku.bili.ui.splash.SplashActivity'

        self.driver = webdriver.Remote('http://localhost:4723/wd/hub',capabilities)
        sleep(5)

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

    def test_bilibili_search(self):
        """搜索测试"""
        self.driver.find_element_by_id('tv.danmaku.bili:id/searchable_search').click()
        sleep(1)
        search_bar = self.driver.find_element_by_id('tv.danmaku.bili:id/search_bar')
        search_bar.click()
        sleep(1)
        search_bar.send_keys("23")
        #self.driver.hide_keyboard()
        self.driver.find_element_by_id('tv.danmaku.bili:id/search').click()
        sleep(1)
        self.driver.swipe(600, 1700, 600, 700)
        sleep(1)

if __name__ == 'TestUnitTest': # 使用 "__main__"需要命令行运行该文件，否则下面代码不会执行
    suite = unittest.TestLoader().loadTestsFromTestCase(TestBilibiliInput)
    unittest.TextTestRunner(verbosity=2).run(suite)

注：该用例使用 Python unittest 单元测试框架
