My Interviews on Mobile Testing

by
My Interviews on Mobile Testing - Adventures in QA

Lately I was interviewed by Ryan Arsenault from Aberdeen Group on the blog TechProEssentials and by Srinivas Kadiyala for the Testing Circus magazine. Both interviews had a focus on mobile testing, my role as mobile tester, my current challenges at work, how I started my career in software testing and how I started my book about mobile testing. Maybe my interviews on mobile testing are interesting for you and will provide you with some new insights in my daily work life.

The following list is an excerpt from the questions I answered for the TechProEssentials:

Mobile Test Pyramid

Mobile Test Pyramid - Adventures in QA

Anyone who is involved in software testing and software test automation should know the test automation pyramid introduced by Mike Cohn (http://www.mountaingoatsoftware.com/).

This article contains excerpts from my book „Hands-On Mobile App Testing“ published with Pearson Education.

As you can see in the following image, the typical pyramid consists of three layers. At the bottom, there is the automated unit-testing layer, in the middle the automated integration testing layer and at the top there is the automated end-to-end testing layer (including the user interface tests). Each layer has a different size, indicating the number of tests that should be written within each stage. Manual testing is not part of the test pyramid, hence it is shown as a cloud for additional testing work.

But this pyramid is not applicable to mobile apps and mobile test automation. Mobile testing requires a totally different set of testing activities like movement, sensors, different devices and networks compared to other software like desktop or web applications. Lots of manual testing is required to be sure that a mobile app is working as expected in the different usage scenarios.

Android M Testing with Doze and App Standby

by
Adventures in QA - Android M Testing with Doze and App Standby

You probably all know that Google has started with the rollout of Android M (Marshmallow). Android app developers and testers must know the new features that are coming with the latest version of Android M. Next to the brand new permission system, Android M also introduces Doze and App standby to save battery.

If a user leaves a device unplugged and stationary for a period of time, with the screen off, the device enters Doze mode. In Doze mode, the system attempts to conserve battery by restricting apps’ access to network and CPU-intensive services. It also prevents apps from accessing the network and defers their jobs, syncs, and standard alarms.
Periodically, the system exits Doze for a brief time to let apps complete their deferred activities. During this maintenance window, the system runs all pending syncs, jobs, and alarms, and lets apps access the network. (Source: Google documentation)

In order to be sure that your app is able to handle Doze and app Standby, Google provided some documentation on that. Here are the steps to make sure your app handles Doze (instructions copied from the documentation):

Testing your app with Doze

You can test Doze mode by following these steps:

Android Tool for Mac

by
Android Tool for Mac - Adventures in QA

If you are a mobile tester or a mobile developer you may not have the problem to create screenshots or videos from the current develop state of your app. You will probably use tools like adb for Android or QuickTime for iOS in order to capture a video. However, this is not the case for prodct owners, scrum master, mobile designer or any other non-technical colleague on the project. They may have not installed the mobile development tools like Android Studio or Xcode.

Thanks to my colleague, Daniel Guse, who pointed me to the tool Android Tool for Mac. With the help of this tool it is very easy to capture screenshots or videos from Android applications right from the desktop.

The tool is offering the following features:

[Reblog] Scaling Mobile at XING: Platform, Framework and Domain Teams

by

At XING, my current employer we had to handle some exciting challenges. We had to scale the whole mobile development as well as mobile testing from two small mobile teams (Android and iOS) to the whole software development department at XING. My colleague Alexey Krivitsky wrote a great blog post about “Scaling Mobile at XING: Platform, Framework and Domain Teams” at InfoQ. … Read more
