Testing is something we have to do but no one really want to do it. Fortunately, Android provides tool for doing automatic testing called "Monkeyrunner"
I just tried it and it works very well. First, we need to prepare all below files stored in the same folder...
1. your application .apk file (ex: yourapplication.apk)
2. your test python script (ex: testing.py)
3. screen captured folder(ex: screenshot/)
In your test python script file, write down testing script ... Some kind like this one below.
# Imports the monkeyrunner modules used by this program
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
# Connects to the current device, returning a MonkeyDevice object
device = MonkeyRunner.waitForConnection()
# Installs the Android package. Notice that this method returns a boolean, so you can test
# to see if the installation worked.
device.installPackage('yourapplication.apk')
# sets a variable with the package's internal name
package = 'your.application.package'
# sets a variable with the name of an Activity in the package
activity = 'your.application.package.MainActivity'
# sets the name of the component to start
runComponent = package + '/' + activity
# Runs the component
device.startActivity(component=runComponent)
#wait 2 sec
MonkeyRunner.sleep(2)
#touch some button
device.touch(65, 215, 'DOWN_AND_UP')
#wait 2 sec
MonkeyRunner.sleep(2)
# Takes a screenshot
result = device.takeSnapshot()
# Writes the screenshot to a file
result.writeToFile('screenshot/shot1.png','png')
Connect your device with your pc and execute testing.py with below shell command ...
$/usr/local/android-sdk-linux_XXXXX/tools/monkeyrunner testing.py
If everything alright then your will have shot1.png file stored in screenshot folder.
