Performance testing: Complete guide with examples you should know

In recent years, it’s beneficial having performance testing on your eCommerce website. This type of testing of any application helps in identifying the performance bottlenecks in the application and hence, considered very critical to the success of any application. Also, this will not only measure the response time of the application but also several other quality attributes like – stability, reliability, robustness, scalability, resource utilization, etc.

With the paradigm shifting from conventional models to continuous delivery, performance testing continues to evolve to deliver future-proof systems to the modern enterprise. So, adapting it has been becoming more beneficial than ever before. So now, we – ArrowHiTech would like to show you guys the complete guide of performance testing, as well as the performance testing example that you should know for your business. Let’s get into it!

Before moving to the performance testing example, let’s explore more about definition and types of Performance testing as well as the basic steps of performance testing

What is performance testing?

This kind of testing is a form of software testing that focuses on how a system running the system performs under a particular load. Performance tests are typically executed to examine speed, robustness, reliability, and application size. Effectively, you can test the system under multiple and different load and network conditions and it scrupulously checks the time taken by the system to respond under these loads.

Why choose performance testing?

You have just finished building the application for your business’s project. The ideas that you brainstormed in your initial meetings have been executed well to give birth to an app. The app looks great, and beta testing ensures the readiness of the software product, as well. However, the first run is not something that lasts long. Also, you may need to measure the handling of your site in order to make changes if necessary.

This is why the best software product development projects of the world go through a thorough performance testing process. Without it, product owners can only play a ‘Guess Game’ regarding the quality of their businesses’ solution. This is the reason why a lot of businesses fall into pieces because of not having this method.

Types of performance testing for software

To understand how the software will perform on users’ systems, there different types of performance tests that can be applied during software testing. Let’s find out.

Types of Performance Testing
Types of this kind of testing

1. Load testing

Load testing simulates the number of virtual users that might use an application. In reproducing realistic usage and load conditions, based on response times, this test can help identify potential bottlenecks. It also enables you to understand whether it’s necessary to adjust the size of an application’s architecture. In other words, the system is monitored to measure response time and system staying power as workload increases.

2. Stress testing

Unlike load testing, stress testing (also known as fatigue performance testing) will measure system performance outside of the parameters of normal working conditions. The software allows more users or transactions that can be handled. Also, these tests significantly and continuously increase the number of users during the testing period. After all, the goal of stress testing is to measure the software stability.

3. Spike testing

Spike testing seeks to understand implications to the operation of systems when activity levels are above average. Unlike stress performance testing, spike testing takes into account the number of users and the complexity of actions performed. Also, the workload is beyond normal expectations for short amounts of time. This is because of the increase in several business processes that generated your store.

4. Endurance testing

Endurance testing — also known as soak testing — is an evaluation of how the software performs with a normal workload over an extended amount of time. The goal of this testing is to check for system problems, observe if intense and sustained activity over time shows a potential drop in performance levels, making excessive demands on the resources of the system. This performance testing will hold the program not to fall into pieces.

5. Volume testing

In Volume testing, we feed the application with a large volume of data. Now, you can do this either by inserting a high volume of data in the database or depending on the application or functionality – uploading a large file for processing. After all, the objective is to check the software application’s performance under varying database volumes. It is also known as flood testing because the test floods the system with data.

6. Scability testing

This type of testing can determine if the software is effectively handling increasing workloads. This can be determined by gradually adding to the user load or data volume while monitoring system performance. Also, the workload may stay at the same level while resources such as CPUs and memory are changable. In other words, this will help to identify the actual number of the users that the system can support with the current hardware capacity.

What does performance testing measure?

Performance testing can be used to analyze various success factors such as response times and potential errors. With these performance results in hand, you can confidently identify bottlenecks, bugs, and mistakes – and decide how to optimize your application to eliminate the problems. Moreover, the most common issues highlighted by performance tests are related to speed, response times, load times, and scalability.

What are the benefits of effective performance testing?

Firstly, performance testing will help increase the customer’s satisfaction. This is by far one of the most important aspects and can be done by sorting out the performance bugs and helping to increase customer satisfaction. Also, the functional characteristics, as well as speed, stability, and accuracy is deeply monitored. Moreover, the errors can also be identified and fixed, which helps the organizations to increase their user volumes for the application.

Realistic tests that provide sufficient analysis depth are vital ingredients of “good” performance tests. It’s not only about simulating large numbers of transactions but anticipating real user scenarios that provide insight into how your product will perform live. The best performance tests are those that allow for quick and accurate analysis to identify all performance problems, their causes and effects.

The basic steps of performance testing

Step 1. Identify the testing environment

Identifying the hardware, software, network configurations and tools available allows the testing team to design the test and identify performance testing challenges early. This kind of testing environment option includes the subset of production systems with fewer servers, lower specifications or with the same specification. It also includes all the replicas and actual production systems.

Step 2. Identify the metrics

In order to identify what are the success criteria for performance testing, you should identify metrics such as response time, throughput, and constraints. This is crucial for your business, as for the future developments may need all these metrics in case of improvements. When you are unable to determine your success criteria, it’s recommended that you find a similar application as the benchmark.

Step 3. Define planning and performance testing scenarios

To carry out reliable tests, it’s necessary to determine how different types of users might use your application. To give it in another way, you need to identify key scenarios and data points that are essential for conducting tests as close to real conditions as possible. After running your tests, you must analyze and consolidate the results. Once the necessary changes are done, tests should be repeated to ensure the elimination of any others.

So do you understand all term above? If YES. Let’s go to the find out performance testing example.
