How to Capture Logs from Windows Phone with Field Medic

Field Medic is the main diagnostic application produced by Microsoft for Windows Phone 8.1 and Windows 10 Mobile. This tool allows us to easily collect the information about a device and logs from your device. This article analyzes the Field Medic application and its usage in testing.

Introduction

Software testing is an important stage of application development which needs much time and money to solve different tasks. Logging is quite an important process of testing, the task of which is to localize the errors in the process of working with different software products.

Installation of Field Medic

There are two ways to install the Field Medic application:

  1. Download it from a store using the following link on the device: download the Field Medic application;
  2. Pre-load the application. The application is included in Mobile OS packages (in the “Field Medic” folder) with a license and offers HTML for partners who want to pre-load the application.

The Main Capabilities

Field Medic is the application which can be used to capture event logs of applications and also separate units of Windows device (ETW – Event Tracing for Windows) for the selected information categories. Field Medic saves files of ETW log and general information in a folder accessible via USB Media Transfer Protocol (MTP). MTP is enabled by default on all popular devices. This allows you to extract output files such as Field Medic reports easily and not using TShell or other testing tools.

System requirements:
* Windows 10 Mobile, Windows Phone 8.1
* ARM architecture

How the workflow looks like

After you installed and ran the application, you will see quite an easy interface. The application does not need any additional settings to start capturing the logs; you just need to click on the “Start logging” button.

The last saved log will be displayed at the top of the list and also its title will include the date and time of log capturing, which makes its search easier and also helps the developers to localize the bug and compare the device’s logs with the server’s logs in case they use the client-server application:

We want to add that Field Medic collects logs not only from the active application but also captures everything happening in all modules of the device.

Comparing Field Medic with Competition

Visual Studio can be an alternative to Field Medic. Visual Studio is a desktop application, it also takes much space on a hard drive and is hard to use. Visual Studio is more appropriate for developers since it has many different add-ons for development. Its advantage is that after project launches you can view a log in real time and even a filter if you need to search for a particular log.

Personal Impression

After analyzing all information mentioned above, I think that Field Medic is rather easy to use, does not need any additional programs, settings and other software which allows it to stay competitive in its field. The application is easily installed from the Windows store and is ready to use after its installation.

Summary

Field Medic is quite easy to install and to use for capturing the logs of a Windows Phone device in real-time mode. The application has a quite wide range of settings in the sense of choosing the modules of the device from which you need to capture logs in a real-time mode which allows us to localize the time, place and reason of the bug and makes it quite useful in software testing services.
