What Is Load and Performance Testing?

Performance testing involves examining the responsiveness, speed, and stability of an application and ensures that a computer, device, network, or software application performs as expected while under specific workload conditions. Performance testing services help in optimizing resource allocation, ensuring compliance with SLAs, and improving system stability. A strong performance testing strategy includes tests that evaluate the reliability, processing speed, data transfer rate, throughput, network bandwidth, and affordable load limit through various performance testing activities.

Load testing ascertains how well the system can manage the anticipated load and spot any bottlenecks, performance problems, or scalability constraints. Our load testing services validate system scalability by assessing how well the infrastructure can handle increasing user loads. To evaluate a software program, system, or website's performance and behavior under typical and peak load situations, load testing services mimic heavy workloads and high traffic volumes on the target system or website.

Mobile Testing Challenge

One of our clients offers enterprise legal matter management solutions and was experiencing business requirements shifting regularly according to their customers’ demands, requiring our client to adopt an agile workflow and an entirely new way of thinking about testing and collaboration across development and QA.

Mobile Testing Solutions

Our team of testing experts took a three pronged approach to make sure that our client’s application performs as expected. The approach included strategy planning so we could adapt to their agile process and create a comprehensive performance testing plan. We then identified and prioritized all of the business-critical workflows to ensure thorough testing took place and developed scripts for testing their prioritized scenarios. These scripts were then integrated with our CI tool for automatic test execution and report generation.

Mobile Testing Results

In the end, our client experienced significant cost savings across several areas, including hardware and testing tool expenses, human resources and change management by identifying performance defects and architectural issues early on by offering greater visibility into overall and specific scenario performance.
