Performance Testing is a kind of testing technique to make sure the application will work under different workloads. Appearance and features are not the major elements promoted by software, the behavior is also a major thing, like time taken to get the output, reliability, accuracy of usage and scalability do the particular task, etc. The ultimate aim of Performance Testing is to defeat performance trouble.

Performance Testing is done to give knowledge about speed, strength, and expandability of the system to contributors. Mostly, Performance Testing discovers what responsibility to be strengthened just before the product goes to deliver out. If we are not analyzing the performance of the system, the software system is likely to deliver with some problems like: poor or lagging while a few users access the same system at a time, deviation across various OS ( operating system) and less usage. Performance testing will observe if the software has an appropriate speed expectation, scalability, and stability specifications under normal workloads. Product is delivered out with low performance is due to improper performance testing and it may lead to a cheap impression that may break down to meet the expected business ambition. Most performance complication rotates around speed, response time, load time and poor scalability. Speed is one of the main aspects of an operation. A slow running system will give up a possible customer. Performance testing is done to make assured an app runs fast sufficient to keep a user’s consideration and enthusiasm. Take a look at the following file of frequent performance complications.

Performance Testing Techniques:

• Load testing – It is the uncomplicated structure of testing coordinate to accept the performance of the system under a set of load. Load testing will conclude in calculating the essential business analytical action and load on the back-end of the system , application server, etc., is also check .

• Stress testing – It is performed to find the upper limit scope of the system and also to figure how the system behaves if the present load goes well above the expected best.

• Soak testing/Endurance Testing – It is used to check the system specification under continuous load. During the soak test, specifications like memory usage are evaluated to find memory leaks or other problems. The aim is to disclose the system’s performance under constant use. Usually, this is done at the last phase of performance testing

• Spike testing – It is done by raising the count of users quickly by a very huge amount and calculating the behavior of the application. The major aim is to check whether the system will be capable to sustain the load.

• Volume testing/Flood Testing – Database is manipulated with huge amount of data and evaluate the nature of complete software. This is conducted for analyzing the system behavior at various volume levels.

• Scalability testing – Here system behavior is calculated by its power to scale up or down the count of user queries.
