Why maintenance is important
Devices that form part of the individual clouds are real devices and as such not built for 24/7 usage under full load. Maintenance of these devices should therefore contain a reboot, among other checks, and be either run by a schedule (for example daily or weekly) or triggered by an action (for example before each main regression suite). The frequency depends on the amount of tests run and the model of devices. Generally, the more tests we execute against a specific device, and the older (or less reliable) the device is, the more often we should reboot the device.
A maintenance script or suite, which would consist of a number of maintenance actions to be performed, can be set up to run in parallel on specified devices.
Actions could include rebooting the device, recovering, resetting WiFi (switching off-on), verifying internet connectivity, verifying if the mobile network or WiFi is connected, installing and uninstalling required apps, and so on.
You can implement maintenance scripts in Appium/Selenium with a programming language of your choice, by using pure REST API calls, or by using PerfectoActions. Previously, it was also possible to use the Perfecto IDE, but with Flash being deprecated by the end of 2020, it is essential to adapt a different solution.
We recommend the following configuration settings:
- At least 8 GB RAM
- At least 2.20 GHz multicore processors
Using PerfectoActions for your maintenance script requires that you:
- Install Python version 3+ and set it as default.
- Install pip. If you experience proxy issues when installing pip, see Configure an experimental proxy.
Run the following command from a command-line window:
Following is a list of usage examples.
|Area||Example||Syntax to use|
|Device operations||List all available devices|
|List all available devices with an optional feature to provide custom logo using the following syntax: |
|List all available devices using your Perfecto username and password|
|List all devices irrespective of device status|
|Reboot, clean up, and get network settings for all devices, in parallel|
Get Devices List parameters and regular expressions using the following syntax:
|Get network settings (such as airplane mode, WiFi, and data) for available Samsung Galaxy devices only, in parallel|
|Repository cleanup||Display older repository items using the following syntax: |
The following example automatically displays repository media items older than 15 days.
|Automatically delete older repository items using the following syntax:|
The following example automatically deletes and displays repository media items older than 15 days.
|User list limitation||Limit or filter the user list using the following syntax: |
|General||Re-run the same execution with a specified sleep time|
|Skip output in HTML format (for faster results in a command-line window)|

Set up scheduling
This section walks you through the steps for setting up the automatic scheduler on Windows, on Mac, or in Jenkins. Expand the steps that apply to you.
- Open Task Scheduler.
Create a new task and enter a descriptive name.Click to view image
- On the Triggers tab, click New.
In the New Trigger dialog box, set the trigger as preferred. For example, select Daily to run the task daily.Click to view image
- On the Actions tab, click New.
- Browse to the
actions.batfile. A sample
.batfile is available here: https://github.com/PerfectoMobileSA/Device_actions_reporter/blob/master/samples/actions.bat
