Appium automation test foundation - appium basic operation API (II)

5、 Send files to the phone and get the files in the phone

（1） send out ⽂ Pieces arrive at ⼿ machine
code snippet ：

#  Import base64 library 
import base64

#  Convert files to binary files 
with open(file_path,'rb') as fp:
    data = str(base64.b64encode(fp.read()),'utf-8')
    # print(data)

#  Send the converted file to the phone 
driver.push_file(path, data)

Parameter description ：
file_path： File path to upload .
path：⼿ Path on the device ( for example ：/sdcard/a.txt)
data：⽂ In piece data , requirement base64 code .
explain ：
Python3.x All Chinese characters are unicode code , You need to import base64 Library for encoding and decoding , First turn the file into base64 Binary files in format , Then transfer the file to the mobile phone , Because the transfer between devices is binary .

（2） from ⼿ Pull in the machine ⽂ Pieces of
code snippet ：

import base64

#  The returned data is base64 Encoded data 
data = driver.pull_file(path) 

# base64 decode 
with open('a.txt','wb') as fp:
    fp.write(base64.b64decode(data)) 

Parameters ：
path：⼿ The path on the device, for example : /sdcard/a.txt
（3） Example ：

# 1. Import appium
import time
from appium import webdriver
import base64

# 2. establish Desired capabilities object , Add startup parameters 
desired_caps = {
    "platformName": "Android",  #  System name 
    "platformVersion": "7.1.2",  #  System version 
    "deviceName": "127.0.0.1:21503",  #  Equipment name 
    "appPackage": "com.cyanogenmod.filemanager",  # APP Package name 
    "appActivity": ".activities.NavigationActivity"  # APP Start name 
}

# 3. start-up APP
#  Declare the mobile phone driver object ( Instantiation webdriver)
#  The first parameter is zero appium Address of service , Need to start the appium service .
#  The second parameter is Desired capabilities object 
#  Let's just pass in these two parameters first .
driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", desired_caps)

# 4. operation APP

# 4.1  Send files to your phone 
file_path = r'C:\Users\L\Desktop\test.txt'

#  Convert files to binary files 
with open(file_path, 'rb') as fp:
    data = str(base64.b64encode(fp.read()), 'utf-8')
    # print(data)

#  Send the converted file to the phone 
path = r'/sdcard/test.txt'
driver.push_file(path, data)

# 4.2  Pull files from your phone to your computer 
#  The path of the file in the phone 
path_app = '/sdcard/test.txt'
#  The returned data is base64 Encoded data 
data = driver.pull_file(path_app)

print(data)

# base64 decode 
with open('test.txt', 'wb') as fp:
    fp.write(base64.b64decode(data))

#  Tips ： The file will be pulled to the directory where the script file is located 

# 5. close APP
time.sleep(5)
driver.quit()

6、 Get the element structure in the current screen （ a key ）

（ That is, get the source code of the current screen ）
The use of API：

driver.page_source

 do ⽤：
     Return to the current page ⾯ Of ⽂ Gear structure , It can provide a premise for the subsequent judgment of whether a specific element exists .

Example ：

# 1. Import appium
import time
from appium import webdriver

# 2. establish Desired capabilities object , Add startup parameters 
desired_caps = {
    "platformName": "Android",  #  System name 
    "platformVersion": "7.1.2",  #  System version 
    "deviceName": "127.0.0.1:21503",  #  Equipment name 
    "appPackage": "com.android.settings",  # APP Package name 
    "appActivity": ".Settings"  # APP Start name 
}

# 3. start-up APP
driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", desired_caps)

# 4. operation APP
#  Get the current source page 
#  Just set the page source code in the home page 
source = driver.page_source
# # print(source)

#  take app Save the page source code to a file 
with open("source.txt", "w", encoding="UTF-8") as fp:
    fp.write(source)

# 5. close APP
time.sleep(3)
driver.quit()

7、 Start other programs within the script app

The use of API：

driver.start_activity(appPackage,appActivity)

 Tips ：appPackage,appActivity Start for the desired app Package name and startup name 

Example ：

#  From management app Page to open the file manager app

# 1. Import appium
import time
from appium import webdriver

# 2. establish Desired capabilities object , Add startup parameters 
desired_caps = {
    "platformName": "Android",  #  System name 
    "platformVersion": "7.1.2",  #  System version 
    "deviceName": "127.0.0.1:21503",  #  Equipment name 
    "appPackage": "com.android.settings",  # APP Package name 
    "appActivity": ".Settings"  # APP Start name 
}

# 3. start-up APP
driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", desired_caps)

# 4. operation APP
#  From settings app Page launch file manager APP
time.sleep(3)

#  First use adb Command to get the package name and startup name of the file manager 
# com.cyanogenmod.filemanager/.activities.NavigationActivity
driver.start_activity("com.cyanogenmod.filemanager", ".activities.NavigationActivity")

# 5. close APP
time.sleep(3)
driver.quit()

8、 Put the application in the background （ a key ）

The use of API：

#  Put the application in the background ( second )
driver.background_app()

Example ：

# 1. Import appium
import time
from appium import webdriver

# 2. establish Desired capabilities object , Add startup parameters 
desired_caps = {
    "platformName": "Android",  #  System name 
    "platformVersion": "7.1.2",  #  System version 
    "deviceName": "127.0.0.1:21503",  #  Equipment name 
    "appPackage": "com.android.settings",  # APP Package name 
    "appActivity": ".Settings"  # APP Start name 
}

# 3. start-up APP
driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", desired_caps)

# 4. operation APP
time.sleep(3)
#  Set app Running in the background 
#  Run the app in the background 5 second , Back to the front desk 
driver.background_app(5)

#  Tips ： Before testing, it's best to put all the background running in the equipment app All shut down .

# 5. close APP
time.sleep(3)
driver.quit()

Tips ： In the test app During hot start , You will often use this command .

a key ： Supporting learning materials and video teaching
