eCommerce Application Testing: Performance Testing – Part 2

eCommerce penetration over the last decade is huge. By the end of 2019, the total online shopping revenue will surpass $3.4 trillion. It has become imperative for businesses to have an online presence to extend their customer reach and maximize their revenues.

Herein, today’s scenario demands more than just a website or mobile app with core functionality rendering. Customers are increasingly looking for seamless and flawless user experience on digital properties. If a website is not performing as per user expectations, they will not think a blink before migrating to a competitor’s website. In extension to our earlier blog that elaborated the importance of user experience testing, performance testing is also critical for an eCommerce application.

From a normal Monday to Black Friday Sale weekend, organizations need to ensure their online channels are always ready to welcome any number of users on the website at a single point of time. With the holiday season approaching fast, it is crucial to ensure eCommerce apps are holiday-ready. Performance testing helps in examining responsiveness, stability, scalability, reliability, speed and resource usage of software and infrastructure.

Here are a few essential points t to incorporate when taking up an eCommerce performance testing effort.

1. Regional/Global Performance Testing

Global businesses need to make sure that their customers across the globe experience high-quality performance that is uniform and flawless. By segregating the performance experience in different geographies, enterprises can identify and analyze specific flaws more efficiently. It could be any issue including server, streamlining remote transactions or enhancing the stability of the local content delivery network.

2. Performance Testing for Mobile Devices

Online sales happening through smartphones has been registering double-digit growth over the past few years. By 2021, mCommerce in the US is poised to surpass 53 percent of the total online retail sales. Hence, it is crucial to ensure an error-free mobile experience to secure more customers.

With more buyers expected to prefer shopping on their mobile devices, retailers need to enhance their performance testing for mobiles and tablets. eCommerce applications have multiple and complex functionalities for versatile utilization. It is crucial to test whether the application is able to load and function properly under peak traffic cases.

Aside from testing the portable end experience of the client, it is also essential to simulate the performance at different network speeds. In several scenarios, severs need to take on more load to manage several parameters including mobile latency. Hence, network speed simulation should be done in conjunction with overall performance testing.

3. Accurate Workload Modeling

The accuracy of performance test results depends largely on the proper simulation of the production environment in your test. It is crucial to acquire the information of all the crucial parameters of AUT during the planning phase for accurate simulation during the performance test effort. Accurate workload model is crucial to identify the right type of user actions for testing under load along with business cases for users and the distribution of users on every scenario.

Here is how this practice helps:

  • Understanding the application and identification of its performance scenarios.
  • Translating of AUT non-functional requirement into performance test SLAs by leveraging workload model.
  • Easy communication and dissemination of information for the performance testing team including AUT performance scenarios and user’s distribution with every relevant stakeholder.
  • Identifying the amount of test data required before kickstarting the work on the tool.
  • Identifying the number of load injectors required for accurate testing. This also helps in right sizing infrastructure usage.

4. Cloud-based Testing

Cloud-based performance testing offers many advantages to the process. These include:

Reliable Performance

Cloud can be used to easily create the maximum number of users required for peak demand during enterprise performance testing. Massive load testing in the cloud is possible with quick scalability to the required capacity.

Global Readiness

Cloud enables test engineers to have access to the worldwide status of the application. Aside, behavior tests can be done for any geography through imitation of virtual clients from diverse geographies to ensure that the site can deal with traffic from any area.


Cloud empowers the organization to scale their computing resources at any speed or reduce them when required, to ensure the operations of application are feasible. Enterprises are paying for only those resources that they are actually using. It empowers to execute tests at any scale or level while keeping the costs in check.

With cut-throat competition among eCommerce players and more customers taking the online shopping route, it has become essential for enterprises to keep the performance of their applications top notch. Businesses need to leverage and factor in competent QA services that help them reach faster response times, throughput, and greater resource utilization levels that meet the performance objectives for applications or websites.

In the last but most crucial part of our eCommerce application testing series, we would be covering Security Testing of eCommerce applications.
