Why Should You Focus On Mobile Performance Testing

Mobile computing needs no introduction today. The increased rate of digitization, its reach amongst the masses, the penetration of newer technologies, have all become possible, thanks to the paradigm changes mobile app development has been bringing in, in the industry.

When mobile rendering started gaining popularity years back, the focus was largely on the overall functionality remaining intact, the sync in-app data between mobile and non-mobile renders and how the app’s UI fared.

Non-functional areas such as security, accessibility and performance testing services were not the top priority. However, in recent years this situation has changed drastically. These non-functional attributes play a significant role in an app’s market acceptance.

It is not just from the end user’s experience standpoint, but also the vast number of scenarios at play now, that makes these attributes important for mobile. For example, WCAG 2.1 version is currently in use and a lot of coverage here is on the mobile pieces of accessibility.  Security vulnerabilities specific to mobile scenarios are also under consideration in determining what the test strategy should be.

Similarly, on the performance testing front, mobile app performance can no longer purely rely on the core client-server performance testing done at the application level.

A solid performance testing strategy today encompasses mobile too, and herein, address performance testing services at varied levels – what used to be just user-facing GUI performance testing is now handled at unit, web services levels increasingly, making room for early performance testing.

Similar to a compatibility matrix that is traditionally used, mobile app performance is having to look at not just the core application but the rendering across devices, operating systems, form factors, network bandwidths amongst others.

While tests are being planned, both front and back end parameters need to be considered. The overall scope has to encompass device performance, network performance and the app level performance which includes client/server/API etc.

A lot of parameters/checklists are available for each of these categories today and a lot of tools are also available to enable mobile performance testing in a fast, cost-effective and comprehensive manner.

Some of the common parameters that are traditionally monitored include application’s initiation and response times, co-existence with other applications, memory usage, API calls, data and packets exchanged to and fro with the server, performance based on overall network speed amongst others.

The kind of tests performed will also vary slightly depending on what kind of a mobile application we need to performance test – whether native, web or hybrid. While most of the parameters above are non-user facing, they impact the end-user ultimately in the form of request-response time the user gets to experience.

While most of these are traditional in a non-mobile set up too, given the scope in using mobile devices have brought in, mobile performance and the experience generated therefrom have become core to an application’s acceptance amongst the masses.

Given these and the scope to test earlier on, mobile performance and in general performance testing services are now offered much earlier in the SDLC bringing down the cost of overall performance engineering efforts.
