利用Robot Framework和Python wrapper of Android uiautomator的Android测试自动化

利用Robot Framework和Python wrapper of Android uiautomator的Android测试自动化

现在有很多工具可以实现BDD，比如Cucumber(http://cukes.info/),用文本来描述行为和结果

不会编程的人看得懂，当然了，底下的工作并没有减少。

这个Robot框架好处有两点，1. 适用广泛，可配置高 2. 报告可读性高

今天我们来弄一下这个过程，比较简单，错误之处希望海函。

1. Robot framework 安装

下载：http://robotframework.org/

安装：sudo python setup.py install

2. 安装https://github.com/xiaocong/uiautomato

sudo pip install uiautomator

echo “export ANDROID_HOME=/your_android_home” > > ~./bashrc

source ~/.bashrc

3. 写用例文本（宏文本）

比如我们这个keyword-driven.txt，按照keyword来写的，注意要用很多tab来分割函数和参数

*** Settings ***
Documentation Example test cases using the keyword-driven testing approach.
…
… All tests contain a workflow constructed from keywords in
… UiTestLib. Creating new tests or editing existing
… is easy even for people without programming skills.
Library UiTestLib

*** Test Cases ***
点亮屏幕
Light screen
Result should be True

打开声音
Open application “com.android.settings/com.android.settings.Settings”
Click text 声音
Click text 音量
Text display on screen contains 铃声和通知
Result should be True

4. 写底层解析脚本

用来解析上面的宏文本，可以看到它是以下划线来命名解析的，只有这样才能达到一一对应。

#!/usr/bin/env python

-- coding: utf-8 --

import uiautomator
from uiautomator import Adb, Device

class UiTestLib(object):
“”“Test library for testing Calculator business logic.
Interacts with the calculator directly using its push method.
“””

def __init__(self):

    self.d = Device('CB512611AE')
    self.adb = Adb('CB512611AE')

    self._result = ''

def light_screen(self):
    """Light screen by wakeup.
    Examples:
    |Light screen|
    Use `Light screen` to light screen.
    """

    self.d.wakeup()
    self._result = self.d.press.home()

def open_application(self, appname):
    """Open application by it name `appname`.
    Example:
    | Open application | "com.android.settings/com.android.settings.Settings" |
    """
    appname = 'shell am start -n ' + appname
    print appname
    self._result = self.adb.cmd(appname).wait()
def click_text(self, text):
    """Click text label on screen
    Example:
    | Click text | text |
    """

    self.d(text = text).click.wait()

def text_display_on_screen_contains(self, text):
    """Verify text display on screen
    Example:
    |Text display on screen is| text |
    """

    if self.d(text=text).exists:
        self._result = True


def result_should_be(self, expected):
    """Verifies that the current result is `expected`.
    Example:
    |  Open application    | com.android.settings/com.android.settings.Settings |
    | Result Should Be | 0       |
    """
    print ( 'result is: %s\n', self._result)
    print ( 'ex is: %s\n', expected)
    if str(self._result)  != expected:
        raise AssertionError('%s != %s' % (self._result, expected))

5. 运行
   pybot keyword_driven.txt

结果就出来了，可读性很强，报告很强大。
