The success of the software quality assurance function within your organization is dependent not only on what automation technology you choose to implement, but also on how that technology is implemented
TESTING SERVICES : LOAD TEST CENTER
Reliability is the key to customer loyalty . Downtime is costly and if your site can’t handle the traffic, your customers will click to one that can. SQA Lab’s load testing center solutions provide businesses with the confidence that their web sites will scale and perform under the heaviest workloads. A load test plan will be developed for your project outlining the testing objectives, approach, scope, test design architecture, and execution plans.
SQA Lab’s Load testing solution center provides expertise to use the latest in sophisticated performance testing tools to simulate tens of thousands of virtual users hitting your servers at once. These virtual users perform typical tasks such as browsing, purchasing items, and searching databases contained within your web site. While these virtual clients are performing these tasks, "probing clients" record exact server response times. We perform capacity testing to determine the maximum load that a web site can handle before failing. Capacity testing reveals your WebServer's ultimate limit.
During the load test , various performance measurements of the system under test are captured and documented. After the tests are performed, the resulting data to evaluate the performance of your site
- Under normal Load - performance testing
- Under anticipated future load - scalability testing
- Under highly abnormal peak load - stress testing
- Under uninterrupted , sustained load0 endurance testing
Some of the key measurements provided include:
- How many simultaneous users the web site can support.
- How many simultaneous transactions the web site can support
- Page load times under various traffic conditions.
- Where bottlenecks are occurring.
- Completed/Abandoned Sessions by Load Level
What is load testing?
- Load testing is a way of measuring the performance of your website. Website software often runs fine with small numbers of users, but breaks down when thousands or millions of people access the site on the public Internet. With load testing, you can predict how the site will function in the real world.
- Rather than test the site at the last minute, just before you go live, it's best to do load testing throughout the development process. This way you can detect hidden bottlenecks or performance problems
What kind of problems could show up?
- Most problems have to do with the bottlenecks that arise when different users depend on a common resource.
- For example, if your site depends on a single, common database, then data access could become an issue if your database queries aren't efficient.
- Incorrect use of multithreading in web server software is another common problem. Excessive disk access or memory leaks also cause problems.
- By identifying these problems early you can rewrite software, reconfigure hardware, or employ caching strategies to get order-of-magnitude performance increases.
