Performance testing is an essential part of the software development process. It is used to evaluate how well a program or web application performs. It encompasses many different types of non-functional testing that analyze the non-functional requirements of an application or environment to evaluate its readiness to perform under various conditions. Performance testing exposes key performance areas such as speed, capacity, consistency, and recoverability.
There are many different kinds of performance testing, and each type of testing will provide mechanisms to assess different aspects of an application or environment. Read this article to learn about the different types of testing, including the most common types and examples.
What are the different types of performance testing?
The types of performance testing in software testing include:
- Load Testing
- Endurance Testing
- Stress Testing
- Spike Testing
- Scalability Testing
- Volume Testing
- Peak Testing
- Throttle Testing
- Security Testing
What are the more common performance tests?
Not all of the above performance tests are common or used in most situations. In fact, some teams are beginning to consider security testing as its own unique entity separate from performance testing altogether. Below are the most common types of performance testing with examples.
Load testing measures an application environment’s performance and response time under expected or specific amounts of use. It typically takes place over at least an hour, and should not push beyond expected amounts of use.
Load testing is designed to test an application environment’s speed and capacity. It determines how many users a program can handle, response time under varied amounts of use, and bottleneck issues related to memory leaks and network delays.
A team might perform a load test by sending a large amount of transactions to a server within a short timeframe to see how well it performs. Historically, load testing was performed manually, but today it is automated with the use of performance testing tools.
Endurance testing, also called soak testing, is a type of load testing that evaluates an application’s ability to handle average or expected amounts of load over a lengthy period of time, from 4 to 24 hours.
Endurance testing is designed to test an application’s capacity after the initial deployment. It is especially important as it can identify potential memory leaks, performance degradation, or connection issues that could hinder performance or cause a system failure over time.
An endurance test may be completed by running an application for hours to see how well it performs.
Stress testing is similar to load testing, but it is performed at significantly increased load levels. It verifies the stability of an application under extremely heavy use. There are several types of stress testing, including application stress testing, transactional, systemic, and exploratory.
The goal of stress testing is to measure an application’s recoverability, or the way it recovers after a failure. Stress testing, then, should push an application to extreme conditions to illustrate when a system failure occurs and how it performs post failure.
As stress testing is designed to push an application to its limits — and beyond — to determine where they are, a sample test could be any business operation that is the focus of the testing. Options could include creating sessions, creating orders, performing searches, or some other combination of business processes that are used to find the limits of the servers.
Like stress testing, spike testing is designed to measure an application environment’s performance under extreme use. However, spike testing specifically assesses performance under unexpected or extreme increases or decreases in load.
Spike testing ultimately seeks to measure an application environment’s consistency and recoverability. It is used to analyze recovery time after an extreme spike to determine how stable it is and how well it recovers.
A spike testing scenario might involve your normal load test, but adds an additional configuration, such as having many users hit a website within a very small window of time, like during the minutes following a flash sale or the stroke of midnight on Black Friday.
Scalability testing measures an application’s ability to perform under gradually increasing or decreasing loads. It is designed to test whether the application can handle the growing need and at what point it stops scaling.
The goal of scalability testing is to measure capacity to ensure that an application can handle regular site growth over time, targeted marketing campaigns, or special seasonal loads.
To run a scalability test, you might gradually increase the amount of network usage on an application to see how it responds.
Volume testing, also referred to as flood testing, measures a server’s ability to handle a large or extreme volume of data. Volume testing can help identify errors that may occur due to a large amount of data.
Volume testing seeks to measure the capacity of your servers. It can enable your company to see your servers operating in ways that require analysis and work to improve their performance.
An example of volume testing would be to load a large amount of new data into your server to see how well it supports the new data set.
Less Common Performance Tests
Here are brief definitions of types of performance tests that are considered less common. While less common, these tests are still worthwhile to perform for many different programs and applications.
- Peak testing is similar to endurance testing, but with a much higher load and a much shorter length of time.
- Throttle testing is done to check how well a system will run for users with low network connectivity.
- Security testing, sometimes considered to be its own measure separate from performance testing, is designed to check for vulnerabilities.
