Performance and Load Testing

Why is Load Testing Important for Web Applications?

In recent times, numerous tools have emerged to try and deal with the conditions and demand for Load-testing.

What’s load testing?

Load testing is the subdivision of performance testing videlicet a system’s ability to work-out under high-user loads.  As workload escalates, load testing succors to understand the performance of the system and particularly associated systems. the moment that is done accurately, load-testing allows teams to substantiate an app’s conduct under both conventional and apex load conditions.

How does load testing Work?

Load test can likely be done with end-to-end IT systems or small-scale components like database servers or firewalls. It measures the speed or capacity of the system or component through transaction response time. When the system components dramatically extend response times or become unstable, the system is likely to have reached its maximum operation. Below listed are a few Use Cases & Examples of the multiple conceivable ones where Load Testing works:

  1. Airline Website During Promotion Period. Evaluating an airline’s website that will be launching a flight promotion offer and is expecting 10,000+ users at a time.
  2. Government Web Portal. Evaluating a website of government agencies, especially during the filing date of income tax returns when traffic will spike.
  3. Running numerous concurrent requests on a server, consequently, subjecting the server to a massive volume of traffic.
  4. The nonstop transfer of multiple files to and from a hard disk.
  5. Downloading a huge volume of large files from a company website to test performance.
  6. Requesting various jobs on printers in a queue simultaneously.

Perks of Load Testing

Cuts down the Cost of Failure:

Cost of spotting performance issues at an early stage is remarkably little, juxtaposed to later stages. If a web app begins to display its bugs after the launch. This can irredeemably damage a company’s honor and reputation; will either have to recall the app and move back to an old version or halt the web app up until all the bugs are fixed. As a consequence, the resulting costs are always going to be taxing for a company and damage it gravely. Load testing enables the detection of these problems before the web app goes into production. Consequently, it’s substantially easier to solve these issues and also do not need to pay the costs of post-launch error removal.

Better Scalability:

When software doesn’t deal with simultaneous users well, it gives on to issues namely poor utilization of resources and memory leaks. Load-testing enables finding-out the limits of their app’s operational capacity. When aware of the system’s limitations, one can easily identify the changes needed to make the app more scalable.

Cuts down the Risk of System Downtime:

Load-testing, together with stress testing, permits testers to replicate real-time app usage under and fluctuating loads. When the system is put through augmented traffic, it can outline issues that cause downtimes. Consequently, it’s effortless to rectify the problems before they cause downtimes, and the overall probability of system-downtime is lower.

Recognize Incompetent Code:

If a product has complicated and intricately written code, subsequently it won’t make use of resources proficiently. Nevertheless, these issues are arduous to dredge-up in conventional circumstances and load testing is needed to recognize these issues.


Load testing is a crucial and essential part of the testing process as it guarantees that the app performs to evince high-user gratification. A victorious load testing lends a hand to releasing high-quality app.
