Performance testing is an integral part of software testing as it helps determine the performance of a system under heavy load. This is typically essential for mobile apps, which receive multiple instruction for download action.  The main testing attributes include speed, scalability, reliability, and stability.

Performance testing is a type of non-functional testing, which strives to build performance standards into the implementation, design and architecture of a system. In other words, performance testing  is not a tool to detect flaws in a system or a software, it rather tests the response time, throughput or the mean time. This, in turn, can be done in different ways depending on the tool, which include user profile, timing delays, different types of activity, and other parameters.

Different techniques of performance testing

Stress Testing:  It is done to determine the upper limit of the system and to determine how the system performs if the pressure goes above the expected level.

Load Testing:   This is done to determine the behaviour of the system in a specific stress environment and how it deals with it. The breakeven point can also be determined when the system starts downgrading its performance.

Portability testing: Software reliability is a probability that the software will perform well in a given environment and for a given amount of time.

Usability Testing: This testing is done to determine the extent to which the software product is understood. It should be easy to learn, easy to operate, and should be attractive to the users who are using the website.

Security Testing: This will point out the vulnerabilities in the software and protect it from potential intruders.

Soak Testing: It is used to detect the system’s stability and performance over a span of time. A non-functional type of testing, soak testing is also known as Endurance Testing. It involves testing a system by providing it with expected amount of load over a long period of time. This is done to determine the behaviour of the system. For instance, a system designed to work for 3 hours is made to work for 6 hours deliberately to check the functionality and endurance.

Spike testing: This is done by increasing the number of users by multiples at a given time to check how the system responds and how well it performs.

Isolation testing:  It is not exclusive to performance testing as such, but involves repeating a test execution that results in an unforeseen problem.

Volume Testing: It is a non-functional testing, which refers to testing a software application with data in bulk to check the efficiency of the application. The main goal of this test is to supervise the performance of application under diversified database volumes.

Scalability Testing: It is a non-functional testing, which involves testing a software application to determine if it can scale up in terms of any of its non-functional capability like the user load supported, the transaction numbers, the volume of data, etc. The main aim of this testing is to understand at what peak the system prevents more scaling.

The success of a software system depends immensely on performance testing since it ensures customer satisfaction and eliminates the risk of product failure. It is important to carry out performance testing before the product rolls out in the market.
