What is Performance Testing?
Performance testing, as the word suggests, is a process that tests the working, functionality, speed, reliability and all other factors that determine the performance of a software, app or piece of code.
There are various steps involved in performance testing including quantitative tests run under limited constraints of the given framework.
For example, a company wants to measure the speed and response time of a software when a user-event occurs like a click of a button that sends a request to the server for processing.
Did you know? One of the known units used for calculating the performance in mainframes is Millions of Instructions per Second (MIPS).
Why Performance Testing is Important?
Performance Testing plays a vital role in identifying many current and possible future issues.
It gives you the ability to highlight parts of the code where the application might lag or fail.
One can also verify if a system meets the functional as well as non-functional requirements asked by the consumer.
Performance Testing predicts and hence helps in preventing possible future downtimes.
On 19th Aug 2013, the search giant Google lost $545,000 because of only 5 minutes of downtime.
How Performance Testing is done?
Following are some of the typical parameters used to define the results of a Performance Testing run:
- Response Rate
- Processing Speed
- Data Transfer Rate
- Network bandwidth & throughput
- Workload Efficiency
Tools Used for Performance Testing
- LoadNinja – is a Load Testing Tool. It is a completely cloud-based tool to analyze and playback detailed load tests. With the use of this tool, Software Testers are able to cut load testing time by 60% or more.
- NeoLoad – is a Performance Testing tool. The NeoLoad testing tool is about 10x faster than the conventional tools being used in the market. This tool provides component-level to complete system-wide load tests.
- HP LoadRunner – is one of the most popular Performance Testing Tools being used in the market today. One of the reasons behind its popularity is its ability to simulate loads and user behaviors to perform load tests. Loadrunner has a feature that simulates live humanlike users and actions.
- Jmeter – is a Load Testing Tool. It is used for load testing various applications and web servers.
