Need for the Right Performance Testing Strategy for your Mobile App

Performance Testing Strategy for Mobile App

Mobile app development teams put a lot of designing and testing efforts to create high-quality mobile apps. They expect them to be used by tens of millions of users. Obviously you don’t expect your apps to be left abandoned, unused, uninstalled, or given poor reviews. 

Building the right mobile app strategy can help you address this major challenge. Even when app glitches and bugs are common, they can be prevented. Performance Testing Services using these tips to build an app testing strategy helps prevent issues significantly.

6 Tips to Create an Effective Mobile App Testing Strategy

The best tips followed by organizations leveraging performance testing services for creating an effective app testing strategy are as follows:

1. Alignment between Test Goals & Business Niche

The types of tests and how performance testing services are integrated will depend on your business’ niche or specialization. The approach to performance testing also needs to be based on the mobile device type that your app will be used on.

  • You business type should determine what tests need to be run and how they should be performed
  • Consider the business’ needs and intentions
  • The test activities must be created to meet those specific requirements

2. Start Testing from the Oldest Device

New mobile device and OS versions are introduced every few months. So when performance testing services build their mobile app testing strategy, this continual version change will be taken into account. The code on a newer device is less likely to work effectively on an older device. So, you should run performance tests starting from an older version of the device or OS and move up from there. Of course, you need to check the user base and support matrix for your application in deciding the scope of test coverage.

  • Start testing with the app installed on the earliest version of the device that your app is meant to support
  • Then test against the app’s release
  • Keep testing against a newer version until the current device or OS version is tested

The chances are high that issues will be caught with the oldest version, first. When issues are found, it will be a safer point to start making rectification.

3. Test While Keeping in Mind the Next Version

New types of devices and apps are constantly being released. performance testing services should prepare their mobile app testing strategy while keeping the next versions and business models in mind. Modern app-based business models require location, interact with the Cloud, raise customer novices, accept payments, and do much more. These functions are possible only because the latest mobile devices support these functions.

Behind all these new mobile devices there are performance testing services that are carefully planned and designed to ensure that all these technologies worked as desired. It will be difficult to decide the next mobile devices and OS versions. Some devices may or may not have their next versions. You can address this challenge by getting prepared.

If you have been in the mobile app development or testing ecosystem for some time, you know that technology keeps evolving. You also know that the speed of evolution is increasingly almost on a daily basis.

4. Create a Progressive Approach to Testing

The right performance testing services follow a progressive approach to testing. The fact is that time is money and you cannot test everything from the very beginning.

  • Maintain limited test scenarios
  • Progress testing based on increasing complexity
  • At the beginning, conduct client testing separately from server-side API testing
  • Conduct load tests on each one before the complete transactions from client to server are tested
  • When testing is done early in the development cycle, test early and more often while keeping in mind that efficient time management is important

When you focus on a limited amount of critical testing points during the early stage, it will give you a clear idea of the potential scenarios that your app can and cannot handle. Every time you face an issue, fix it before moving to the next stage.

5. Understand the Different Carrier Networks

Your mobile app performance testing strategy should also take into account the carrier network available today. Modern devices will mostly use carrier networks to access the server. These networks are different in terms of their bandwidth, latency and speed.

Performance testing services must include carrier network testing into their app testing strategy to identify and address the way the app works across different types of networks. This component has a huge impact on the end-user experience.

6. Prepare for Interruptions

Mobile users will face more interruptions than their PC counterparts. This is because the way mobile devices are used is different from how PCs are used. With a computer, when you switch between different windows, different applications keep running in the background. With a smartphone or tablet, users can be using an app when they can receive a phone call. So interruptions are a common part of the user experience (UX) and should be considered when building the app testing strategy. Make sure to account for all types of interruptions that can occur with mobile devices.

Categories of App Performance Testing Strategy

When it comes to performance testing services for mobile apps, the following 3 categories must be addressed:

1. Device Performance

A slow performing app can send off many users. The device performance testing component of your app testing strategy must cover the following areas:

i. App Start-Up

Check the time taken by the app to start up. Once the user taps on the icon, the app’s main screen must appear no more than 2 seconds later.

ii. Battery Time

Check how quickly the app drains the device’s battery life. It is also important to check whether the use of the app heats up the device. This is an important factor and is usually associated with the use of resources. Excess resource use can create more load on the CPU and other components and heat up the phone.

iv. Memory Usage

Performance testing services should also include memory usage tests as part of the strategy. Adding certain types of functionalities to an app can have a huge impact on memory consumption. Sometimes, a single app can consume memory equivalent to that used by the OS.

v. Test on Different Software & Hardware

The strategy should also focus on testing your apps on different mobile devices. Apps can run smoothly on one device, but not on another one. For example, the Android platform is used by many different phone manufacturers. It is also important to test apps on different resource specifications – for example CPU speeds and RAM.

The device performance testing strategy must also test your app based on its usage with other apps and its functioning in the background.

2. Server/API Performance

Performance testing services must also cover testing for server/API performance as part of the strategy. When an app interacts with the server through API, the response time will have a big impact on performance. Your strategy must measure service performance based on the following factors:

i. Data Transfer

  • The data from the server must be handled efficiently
  • Loading data should not be a time consuming process
  • All data formats should be converted into relevant formats

Test whether the app is slowing down or response times are becoming longer.

ii. Test App Generated API Calls

Check whether the app is generating multiple API calls for a single functionality. Ideally, the number of calls from the app to the server must be low for optimal performance.

iii. Server Down Time

There should be provisions in the strategy for any server down time.

  • If the server is down, the data should be savable in the native database
  • If one server is down or under maintenance, a backup server should take over

3. Network Performance

As already mentioned above, performance testing services will include multi-network testing as part of the app testing strategy. Network performance testing should cover the following areas:

i. Jitters

Any delay in receiving information on the network is referred to as jitters. It occurs due to issues with the following:

  • Packet switch networks
  • Connectionless networks

The information is broken into packets and it travels by different paths between the sender and receiver. When the packets arrive at the receiver end, it can get scrambled. It is important that your app must be able to handle the scrambled packets to recreate the information. It is important that the system creates proper notifications for resending a request or waiting for the system to respond.

ii. Network Speeds

It is important that your testing strategy should involve app testing on a wide range of networks with different speeds. This includes testing on all the spectrums which are currently in use, ranging up to 4G and even 5G wherever it is available. It is important to test on both mobile networks and Wi-Fi. The app’s behavior must be monitored, even when switching between different networks.

So, it is important to address all these points when building the right performance testing strategy for your mobile app. You should cover all existing and potential scenarios to ensure that your app is fully ready before a release. Building such a strategy should help you prevent or reduce the chances of user migration.
