Load Testing

Automated Testing

We do Mobile App Test Automation using Appium/Robotium, and Web Product Test Automation using Selenium. We have deep expertise on various other tools like QTP, Sikuli, GenyMotion, TestComplete, JMeter etc.

Load Testing

Load Testing

Load testing generally refers to the practice of modeling the expected usage of a software program by simulating multiple users accessing the program concurrently. As such, this testing is most relevant for multi-user systems; often one built using a client/server model, such as web servers. Load testing is performed to determine a system behavior under both normal and at peak conditions. Load testing differs from stress testing, which evaluates the extent to which a system keeps working when subjected to extreme work loads or when some of its hardware or software has been compromised. The primary goal of load testing is to define the maximum amount of work a system can handle without significant performance degradation. The most accurate load testing simulates actual use, as opposed to testing using theoretical or analytical modeling.
Load and performance testing analyzes software intended for a multi-user audience by subjecting the software to different numbers of virtual and live users while monitoring performance measurements under these different loads. Load and performance testing is usually conducted in a test environment identical to the production environment before the software system is permitted to go live. It helps to identify the maximum operating capacity of an application as well as any bottlenecks and determine which element is causing degradation. E.g. If the number of users are increased then how much CPU, memory will be consumed, what is the network and bandwidth response time. At Vigopa, we have been providing custom software development and QA testing services to our happy clients.

Identify performance acceptance criteria- This is the most valuable aspect in the load testing life cycle, and therefore should be recorded and available for review and evaluation.

Response time- This refers to the time taken for one system node to respond to the request of another. It is a difficult thing for load testing tools to deal with as they generally have no concept of what happens within a node apart from recognizing a period of time.

Throughput- If a system identifies end-users by some form of log-in procedure then a concurrency goal is highly desirable. If the system has no concept of end-users then performance goal is likely to be based on a maximum throughput or transaction rate.

Maximum user load- The objective here is to determine the maximum users that can access the application at a specific hardware configuration.

Internet speed and Peak usage time- Website performance over various connection speed e.g. modem, lease-line etc.

Create a workload model- This will determine the characteristics of the key scenarios based on our key user group.
With our expert team of Load and Performance testers, we help to ensure that streamlined efforts are also being aligned towards this very important aspect of development. We can give you a fast, cost-effective insight into how your web applications will cope with higher traffic.
