At the time of developing software in an agile environment, you should pay special attention to performance testing. Performance testing is a software testing method for evaluating a software application’s speed, reaction time, stability, dependability, scalability, and resource use under a certain workload. The basic goal of performance testing is to find and remove performance bottlenecks in software applications. It is also known as “Perf Testing” and is a subset of performance engineering.
During performance testing, you will be paying attention to three important features of software. They include stability, scalability, and speed. Performance testing is carried out to offer information to stakeholders about their application’s performance, stability, and scalability. Performance Testing, moreover, reveals what has to be addressed before a product is released to the market. Without performance testing, software is more likely to have issues like slowness when several people are using it at the same time, inconsistencies across various operating systems, and poor usability.
You can do multiple types of performance testing on a software. They include load testing, stress testing, volume testing, spike testing, endurance testing, and scalability testing. These tests can help you to overcome common performance related problems, including poor scalability, poor response time, long load time, and bottlenecking.
To begin performance testing, you should prepare the testing environment and discover performance acceptance criteria. Then you can plan the performance test and configure the test environment accordingly. The next step would be to implement performance testing design and run the rest. You can analyze the results, tune, and continue to retest. You should continue this until you end up with getting desired results.
