Robot Framework + Appium
Appium-Python-Client: 与Appium Library和Appium Server的交互
Appium Library通过Appiium-Python-Client请求Appium Server初始化一个Session，请求成功后，Appium Server分配给Appium-Python-Client一个Session ID, 后续所有的交互都是通过这个Session完成。
一、测试用例编写前提
所需的软件列表如下
- Robotframework
- Appium desktop
- Android模拟器--夜神模拟器
- 测试的apk文件
pip install robotframework-python3 / pip install --upgrade robotframework 安装最新版本
pip install --upgrade robotframework-seleniumlibrary 直接安装该包会自动安装selenium和robotframework
pip install --upgrade robotframework-appiumlibrary (1.4.6) 直接安装该包会自动安装Appium-Python-Client和robotframework
1.模拟器/手机连接电脑 adb connect 设备型号 （夜神模拟器对应的设备型号：127.0.0.1:62001）
2、启动appium server （打开 appium desktop即可）
二、测试用例编写步骤
1.创建测试项目
File-New Project，选择类型Directory type
2.创建测试套件
测试项目-New Suite，输入Name，选择类型File type
3.创建测试用例
测试套件-New Test Case，输入Name
4.导入测试库AppiumLibrary
测试套件Edit标签页-Library，输入Name：AppiumLibrary
注：导入的库显示为红色时，表示导入的库不存在；如果是黑色，则表示导入成功
5.编写测试用例
测试用例Edit标签页，输入Keywords
注：关键字显示蓝色，说明它是一个合法的关键字，后面为红色说明需要输入一个参数
三、关键字封装
封装的所有关键字代码展示如下
*** Settings ***

*** Variables ***
{REMOTE_URL} http://127.0.0.1:4723/wd/hub
{PLATFORM_NAME} Android
{PLATFORM_VERSION} 4.4.2

{APP} D:\\ContactManager.apk
{APP_PACKAGE_NAME} com.example.android.contactmanager
{APP_ACTIVITY} .ContactManager
*** Test Cases ***

Page Should Contain Text Appium User
*** Keywords ***
add new contact
[Arguments] {contact_name} {contact_phone} {contact_email}
Open Application {REMOTE_URL} platformName={PLATFORM_NAME} platformVersion={PLATFORM_VERSION} deviceName={DEVICE_NAME} app={APP} appPackage={APP_PACKAGE_NAME} appActivity={APP_ACTIVITY}
Click Element accessibility_id=Add Contact
Input Textid=com.example.android.contactmanager:id/contactNameEditText contactname
InputTextid=com.example.android.contactmanager:id/contactPhoneEditTextcontactname
InputTextid=com.example.android.contactmanager:id/contactPhoneEditText{contact_phone}
Input Text id=com.example.android.contactmanager:id/contactEmailEditText ${contact_email}
Click Element accessibility_id=Save
注：每个“{ }”前都有一个“$”
1、RF向Android发送keycode键盘事件
如何向Android发送keycode键盘事件，这是在Android测试中必不可少的部分。我们今天要谈到的keyword就是“Press Keycode”，它有2个参数keycode 和 metastate=None。第二个参数metastate，主要代表是否有Shift/Alt这些Function键按下，对于Android而言很少用到，我们在此就不谈了，直接赋值"None"即可。
要向系统发送返回事件，参考代码如下，
${KEYCODE_BACK} 4
Press Keycode ${KEYCODE_BACK} None
注意，需要事先声明“KEYCODE_BACK”，否则robot framework不能识别。
2、RF判断Android屏幕是否含有某个控件
在用RF写测试代码时, 有时需要判断当前屏幕是否含有某个控件, 以便决定下一步的测试步骤。比如, 测试WiFi的时候, 点击某个无线AP的名称, 如果Android机器已经和这个无线AP连接, 则会跳出询问是否忘记与该无线AP的连接; 如果Android机器还没有和这个无线AP连接,则会跳出页面, 要求输入无线AP的密码.。在RF中,我们可以使用关键字 "Get Matching Xpath Count" 来判断当前屏幕是否包含某个控件，这个关键字的输入参数是"xpath", 输出参数是当前屏幕包含此控件的个数。比如, 下面的代码作用是获得当前屏幕中含有文字"Forget"控件的个数, 如果含有这个控件, 说明WiFi已经连接上, 我们则点击 "Forget" 按钮. 示例代码如下,
${count} Get Matching Xpath Count xpath=//*[contains(@text, 'Forget')]
Run Keyword If ${count} > 0 Log WiFi already connected, forget it then re-connect
Run Keyword If ${count} > 0 Click Element xpath=//*[contains(@text, 'Forget')]
3、RF如何等待Android屏幕中的某个控件出现
在用RF写测试代码时, 有时需要等待当前屏幕出现某个控件以便进行下一步的操作，我们可以用"Get Matching Xpath Count"关键字来实现循环等待某个控件的出现，也可以用另外一个更好用的关键字"Wait Until Page Contains Element", 它有三个参数,
参数1 locator --- 指定要等待的控件;
参数2 timeout --- 指定等待超时的时间;
参数3 error --- 等待失败的错误信息, 也可以使用"None"表示不输出错误信息;
比如在测试WiFi时, 我们要刷新等待某一个SSID Name(无线AP的名字)的出现, 则可以使用下面的代码，其含义为：
在10秒内等待某个SSID名称的出现, 如果没有出现则打印错误日志"Can NOT find ${ssid_name}"; 若出现则可以点击这个无线AP的名称进行下一步的操作
Wait Until Page Contains Element xpath=//*[contains(@text, '${ssid_name}')] 10 Can NOT find ${ssid_name}
Click Element xpath=//*[contains(@text, '${ssid_name}')]
4、RF在Android中实现滚屏
在使用RF试Android机器过程中, 经常要用到滚屏操作, 其中一个方法, 就是使用关键字"Swipe", 这个关键字的效果类似模拟操作人员滑动屏幕的效果, 它有5个参数
----start_x: 滑动开始的X坐标;
----start_y: 滑动开始的Y坐标;
----end_x: 滑动结束的X坐标;
----end_y: 滑动结束的Y坐标;
----duration: 滑动持续的时间, 默认是1000ms;
下面的代码表示, 滑动坐标从(400, 1000)开始, 结束于(400, 500), 滑动持续时长为200ms. 只是一个向上滑动的动作.
Swipe 400 1000 400 500 200
在实际操作过程中, 滑动到某个控件出现的位置.如果滑动太少, 则看不到这个控件; 如果滑动太多, 则会划过这个控件. 这时, 我们可以考虑每次滑动的幅度小一些, 同时通过关键字"Get Matching Xpath Count"查看该控件是否已经出现在当前屏幕.示例代码如下,
下面的代码表示, 每次向上划动一点, 然后查看"About phone"是否出现, 如果出现, 则退出循环停止滑动; 否则继续滑动.
: FOR ${i} IN RANGE 20
\ Swipe 400 1000 400 800 400
\ ${count} Get Matching Xpath Count xpath=//*[contains(@text, 'About phone')]
\ Exit For Loop If ${count}>0
另外, 也尝试了关键字"Scroll Up"和"Scroll Down", 但是没有效果, 不知道什么地方出现了问题.
5、RF对Android的控件定位
使用R F测试Android的过程中, 一定要经常对Android的控件定位。Appium中提供了Xpath进行定位, 就是通过层级一层一层去定位控件。
Xpath定位, 可以通过下面几种方式定位,
1. 通过文本text定位
举例说明, 用户要点击Setting页面中的"About phone"标签, 可以通过下面的语句实现,
Click Element xpath=//*[contains(@text, 'About phone')]
2. 通过resource-id定位
举例说明, 用户要点击Camera App屏幕上的前后摄像头切换按钮, 可以通过下面的语句实现,
Click Element xpath=//*[contains(@resource-id, 'id/front_back_switcher')]
3. 通过content-desc定位
举例说明, 用户要把Camera App切换成摄影模式, 首先点击Camera模式切换按钮, 下面点击切换到摄像模式, 在切换到摄像模式的时候, 是通过content-desc对控件进行定位,
Click Element xpath=//*[contains(@resource-id, 'id/camera_switcher')]
Sleep 1s
Click Element xpath=//*[contains(@content-desc, 'Switch to video')]

Robot Framework + Selenium
一、安装seleniumlibrary库
如果已经安装了pip，则使用管理员模式打开windows命令行，输入pip install robotframework-seleniumlibrary，安装完成后在命令行输入pip list查看python的安装列表，列表中出现了robotframework-seleniumlibrary及对应的版本号，说明安装完成。
二、导入seleniumlibrary库
添加完成，黑色示添加的库正常，红色表示库不存。如果为红色，请检查C:\Python37\Lib\site-packages 目录下是否有 SeleniumLibrary 目录
三、第一个例子
比如打开百度，输入一个Open Browser关键字，如果关键字为蓝色说明它是一个合法的关键字，后面有一个方框是红色的，表示这个参数不能缺省的。通过说明信息中，我发现它需要一个 url 地址是必填的，当然还需要指定 browser （默认不填为 friefox）
四、元素定位
Web 自动化测试其实就是找到元素（定位元素）并操作元素。SeleniumLibrary 提供了非常丰富的定位器：
最常用的其实是id、name、xpath、css。 id 和 name两种定位方式非常简单且实用， xpath 和 css两种定位方式足够强大，可以满足几乎所有定位需求。
1、id和name定位
以百度为例。我们可看到输入框input元素有id和name属性，百度一下按钮有id属性。
输入框：id=kw name=wd，在 Robot framework 中就是这样写的：
Input text 用于输入框的关键字 ，后面两个参数，一个是元素的定位，一个是输入框输入的值。
百度一下按钮：id=su，在 Robot framework 中就是这样写的：
click button用户点击按钮的关键字，后面跟着一个必填参数。
2、xpath定位
XPath 是一种在 XML 文档中定位元素的语言。因为 HTML 可以看做 XML 的一种实现，所以 selenium用户可是使用这种强大语言在 web 应用中定位元素。如果一个元素没有id和name或没有唯一标识可以使用xpath 通过层级关系找到元素。
（1）xpath绝对路径
比如百度页面的搜索输入框xpath=/html/body/div[2]/div[1]/div/div[1]/div/form/span[1]/input。绝对路径的用法往往是在我们迫不得已的时候才用的。大多时候用相对路径更简便
（2）xpath的相对路径
使用元素本身定位：比如百度页面的搜索输入框xpath=//*[@id="kw"]，可以利用元素自身的属性。//表示某个层级下，*表示某个标签名。@id=kw表示这个元素有个 id 等于 kw
当然，一般也可以制定标签名：xpath=//input[@id="kw"]元素本身，可以利用的属性就不只局限为于 id 和 name ，如：Xpath = //input[@autocomplete=’off’]，但要保证这些元素可以唯一的识别一个元素。
找上级：如果一个元素找不到可以先找到他的上级。比如：xpath = //span[@class='bg s_btn_wr’]/input，如果父级没有唯一标识，还可以继续往上找：
xpath = //form[@id=’form1’]/span/input
布尔值写法：
Xpath = //input[@id=’kw1’ and @name=’wd’]
总结：使用过程中发现xpath定位有时候语法并没有任何问题也定位不到元素，比如xpath = //span[@class='bg s_btn_wr’]/input。
3、css 定位
CSS(Cascading Style Sheets)是一种语言，它被用来描述 HTML 和 XML 文档的表现。CSS 使用选择器来为页面元素绑定属性。这些选择器可以被 selenium 用作另外的定位策略。CSS 可以比较灵活选择控件的任意属性，一般情况下定位速度要比 XPath 快。
CSS 选择器的常见语法：
五、SeleniumLibrary 常用关键字
1、浏览器驱动
open browser也可以打开本地的文件，比如：
2、关闭浏览器
（1）关闭当前页面
（2）关闭所有页面（关闭所有打开的浏览器和浏览器缓存重置。）
3、浏览器最大化
4、设置浏览器窗口宽、高
5、获取浏览器窗口尺寸
6、文本输入
7、点击元素
Xpath=//* [@] ：表示元素定位，定位点击的元素。
8、点击按钮
Xpath=//* [@] ：表示元素定位，定位点击的按钮。
9、等待元素出现在当前页面
Arguments:[ locator | timeout=None | error=None ]，
Xpath=//* [@] ：表示元素定位，这里定位出现的元素。
40 ： 表示最长等待时间。
Error ： 表示错误提示，自定义错误提示，如：“元素不能正常显示”
10、固定时间休眠
11、注释
12、获取 title
我们通常会将获取的 title 传递给一个变量，然后与预期结果进行比较。从而判断当前脚本执行成功
13、获取元素的text
Arguments:[ locator ]，Returns the text value of element identified by `locator`.
14、获取元素的属性值
id=kw@name：id=kw 表示定位的元素。@nam 获取这个元素的 name 属性值。
15、cookei 处理
get cookies 获得当前浏览器的所有 cookie 。
get cookie value 获得 cookie 值。key_name 表示一对 cookie 中 key 的 name 。
add cookie 添加 cookie。添加一对 cooke （key：value）
delete cookie 删除 cookie。删除 key 为 name 的 cookie 信息。
delete all cookies 删除当前浏览器的所有 cookies。
