Performance testing tutorials -
Some extremely popular sites have suffered serious downtimes when they get massive traffic volumes. E-commerce websites invest heavily in advertising campaigns, but not in Load Testing to ensure optimal system performance, when that marketing brings in traffic. Loading testing identifies the following problems before moving the application to market or Production:.
Load testing will determine whether the system needs to be fine-tuned or modification of hardware and software is required to improve performance. To effectively conduct load testing, you can utilize various performance testing tools that are available to help you identify areas for improvement.
The chief metric for load testing is response time. Before you begin load testing, you must determine —.
There are many numbers of ways to perform load testing. Following are a few load testing strategies-. Load runner is HP tool used to test the applications under normal and peak load conditions. Load runner generates load by creating virtual users that emulate network traffic.
It simulates real time usage like a production environment and gives graphical results. Read more about Loadrunner here. Skip to content. Table of Content:. You Might Like: What is Software Testing?

Then you may have the consider option of increasing CPU power. During the actual performance test execution, vague terms like acceptable range, heavy load, etc. are replaced by concrete numbers.
Performance engineers set these numbers as per business requirements and the technical landscape of the application. There are a wide variety of performance testing tools available in the market. The tool you choose for testing will depend on many factors such as types of the protocol supported, license cost, hardware requirements, platform support etc.
Below is a list of popularly used testing tools. Performance Testing is always done for client-server based systems only. This means, any application which is not a client-server based architecture, must not require Performance Testing.
For example, Microsoft Calculator is neither client-server based nor it runs multiple users; hence it is not a candidate for Performance Testing. It is of significance to understand the difference between Performance Testing and Performance Engineering.
An understanding is shared below:. Performance Testing is a discipline concerned with testing and reporting the current performance of a software application under various parameters.
Performance Engineering is the process by which software is tested and tuned with the intent of realizing the required performance. This process aims to optimize the most important application performance trait i.
user experience. Historically, testing and tuning have been distinctly separate and often competing realms. In the last few years, however, several pockets of testers and developers have collaborated independently to create tuning teams. Because these teams have met with significant success, the concept of coupling performance testing with performance tuning has caught on, and now we call it performance engineering.
In Software Engineering , Performance testing is necessary before marketing any software product. Costs of performance testing are usually more than made up for with improved customer satisfaction, loyalty, and retention.

During soak tests the parameters such as memory utilization is monitored to detect memory leaks or other performance issues.
The main aim is to discover the system's performance under sustained use. Spike testing - Spike testing is performed by increasing the number of users suddenly by a very large amount and measuring the performance of the system.
The main aim is to determine whether the system will be able to sustain the workload. Home Coding Ground Jobs Whiteboard Tools.

Performance Testing. Testers should be empowered to set performance criteria and goals because often the project specifications will not include a wide enough variety of performance benchmarks. Sometimes there may be none at all. When possible finding a similar application to compare to is a good way to set performance goals.
Determine how usage is likely to vary amongst end users and identify key scenarios to test for all possible use cases. It is necessary to simulate a variety of end users, plan performance test data and outline what metrics will be gathered.
Consolidate, analyze and share test results. Then fine tune and test again to see if there is an improvement or decrease in performance.
Since improvements generally grow smaller with each retest, stop when bottlenecking is caused by the CPU. Then you may have the consider option of increasing CPU power. During the actual performance test execution, vague terms like acceptable range, heavy load, etc.

Performance Testing. Last updated on April Perfprmance, Performance testing of any application helps in identifying the Sports massage therapy bottlenecks Pwrformance the application and hence, Performance testing tutorials considered very critical to the success of any application. In performance testing, we not only measure the response time of the application but also several other quality attributes like — stability, reliability, robustness, scalability, resource utilization, etc. Check our Performance Testing with JMeter tutorial here.
