How to perform Interruption testing in Mobile Applications?
Amidst the hustle and bustle of our modern digital era, mobile applications have become part of our daily lives, from entertainment to productivity. Today, Smartphones are built to enable users to multitask with ease, often switching between multiple apps simultaneously. However, what happens when a call comes in, or a message notification disrupts the user experience? The ability of a mobile application to handle interruptions properly can make or break a user’s experience. That’s why it’s crucial to perform interruption testing in mobile applications before release.
In this blog, we will delve into the world of interruption testing, exploring what it is, how to conduct it, and providing you with a checklist to kickstart your journey into interruption testing for mobile applications.
What is Interruption Testing?
Interruption testing, a crucial facet of mobile app testing, involves assessing a mobile application’s capability to respond to and recover from unexpected disruptions seamlessly.
Imagine you’re in the midst of an online transaction within an e-commerce mobile app when you receive an important message. You switch to check the message and return to the e-commerce mobile app; you discover that all the items you had added to your cart have vanished. This scenario reveals that the e-commerce app fails to restore its previous state after an interruption.
The main goal of interruption testing is to ensure an application maintains its integrity throughout and after interruptions, ultimately delivering users a seamless and uninterrupted experience.
Categories of Interruption Testing in Mobile Applications
The three categories of interruption testing in mobile applications revolve around the diverse sources of interruptions a mobile app may encounter. These interruptions can stem from the device’s native functions, other applications, or alterations in the network. Let’s delve into each of these categories in greater detail.
This category encompasses interruptions linked directly to the device under examination. It does not involve interactions with other mobile applications. Examples of scenarios falling into this category include the device locking itself, adjustments in volume, device shutdowns or restarts, and similar occurrences.
This category encompasses a blend of other applications and device functions resulting in disruptive events. These events can be incoming calls, messages, or notifications from other mobile apps, typically presented as pop-up alerts or push notifications.
This category covers interruptions that occur during transitions between different network types. For instance, it includes scenarios like switching from a Wi-Fi connection to a mobile network when out of Wi-Fi range or shifting between 5G, 4G, or 3G networks based on the available network coverage in a specific location.
Types of Interruptions in Mobile Applications
Mobile applications can encounter various interruptions, many of which are quite familiar. These interruptions encompass but are not limited to:
- Incoming phone calls
- Incoming messages
- Charging a device while using a mobile application
- Disconnecting a device while using a mobile application
- Alarm notifications
- Network disconnection
- Network switching
- Low battery
- Full battery
- Network restoration
- Device shutdown
- Clicking on an external link
- Changing network providers while using a mobile application
Handling Interruptions: How Mobile Apps Respond
Regarding interruption testing in mobile applications, ‘resolution’ refers to the steps a mobile app takes to manage and recover from an interruption. When an interruption disrupts the use of a mobile application, the application is expected to respond in a way that keeps the user’s experience smooth and uninterrupted. Here are some common ways in which interruptions can be resolved:
This approach involves the mobile application currently in use, able to display messages from the device or other apps in a non-disruptive manner. These messages typically appear as alerts or notification banners, allowing the user to read, dismiss, or respond to them without leaving the mobile application entirely.
Run in the background
In some cases, an interruption takes precedence while the mobile app gracefully steps into the background. For instance, if a user is navigating with a map application and receives an incoming call, the navigation app can continue running in the background. This allows the user to answer the call without losing track of their route. Once the call concludes, they can seamlessly return to the navigation app without any noticeable interruption.
Call to Action
Sometimes, an interruption may require input or a decision from the user. For example, while playing a mobile game, a user might receive a notification about critically low battery levels. The app can display a message prompting the user to enable a power-saving mode to conserve battery life. The user can then choose to activate this mode while enjoying the game.
In specific scenarios, an interruption may have negligible effects on the application’s operation and the user’s experience. For instance, no alert or action is necessary when a device is plugged in for charging while an app is in use. The application continues to function seamlessly, ensuring the user can carry on without immediate interaction or disruption.
How to Perform Interruption Testing In Mobile Applications
When performing interruption testing in mobile applications, the objective is to simulate interruptions and assess how the application responds and recovers. Here’s a step-by-step guide on how to carry out interruption testing effectively:
1. Identify critical scenarios
Begin by pinpointing the interruptions relevant to the mobile application that could potentially impact the user experience. Focus on common interruption scenarios, such as incoming calls, messages, alarms, low battery warnings, and network disruptions.
2. Create Test Cases
Once you’ve identified these interruption scenarios, develop comprehensive test cases. These test cases should outline the expected behavior of the mobile application in response to each identified interruption, along with the desired outcome following the resolution of the interruption.
3. Prepare the Testing Environment
Ensure you have a suitable testing environment in place for conducting interruption testing. You may opt to employ tools or scripts to automate the initiation of interruption events.
4. Implement Automation
Consider the benefits of automation in enhancing the coverage and efficiency of your interruption testing efforts. Utilize automation tools or frameworks to streamline the process. Automation allows for repetitive testing, ensuring consistency and speed.
5. Execute the Test Cases
To guarantee comprehensive coverage, perform testing across various mobile devices and operating systems, encompassing both Android and iOS platforms. Throughout the testing process, closely observe how the application reacts during interruptions and assess its behavior post-interruption.
6. Analyze the Test Results
In this phase, meticulously review the test results to uncover any issues or unexpected behaviors that emerged during testing. Determine whether the application performed as anticipated in each interruption scenario and identify areas where improvements may be warranted.
Automating Interruption Testing
Automating interruption testing entails the utilization of dedicated testing tools and frameworks to seamlessly replicate interruptions, eliminating the need for manual oversight. This approach, known as automated interruption testing, empowers QA teams and developers to comprehensively assess their mobile applications’ responsiveness to diverse interruption scenarios.
Automated testing effectively replicates real-world disruptions, ensuring that the application can adeptly pause, restart, and recover data, thus safeguarding a seamless user experience, even in challenging situations.
To unlock the extensive benefits of software testing automation, software development, and testing teams can explore a variety of automated testing platforms available in the market.
