Performance testing best practices -

Will it crash, or will it be capable of handling such a high amount of data. Load testing plays the most critical role in performance testing.

In this, an application's performance is measured by loading it with multiple users concurrently to evaluate the application's capacity to handle the load.

The main motive of load testing is to make sure that our application does not crash if some amount of load is given to it for a specific time period.

Multiple virtual users are sent to the application simultaneously or concurrently to assess the software's behavior. For Example: The Cowin application resulted in a server crash when multiple users rushed concurrently for vaccination registration. So to identify such bottlenecks and to protect applications from crashing, load testing is performed.

Performance testing plays a crucial role in an application's development. So to enhance the quality of an application, it is essential first to prioritize the application's performance. So every QA should keep in mind that the application should not be made QA approved only based on Functional testing.

Still, non-functional testing should be assessed appropriately before making an application live. TestOps Performance Testing Tools and Best Practices - XenonStack Navdeep Singh Gill 30 May Table of Content In this Article.

Key Elements for a Successful Cloud Migration? What is Performance Testing? Performance Monitoring is a tool that enables end users, administrators and organizations to gauge and evaluate the performance of a given system.

Taken From Article, Performance Monitoring Tools and Management Performance Testing Metrics Throughput : It assesses the no. of units a system can process over a specific period of time. Memory : It evaluates that How much space is available for a processor to function.

Response time or latency : It calculates the time at which the response was received for the sent request. Bandwidth : It calculates the amount of data per second that is migrated across a network. CPU interrupts per second : It calculates the number of interrupts per second.

Performance Testing Benefits and Advantages Improve optimization and load capability. Identify discrepancies and resolve issues. Measure the accuracy, speed, and stability of the software.

Validate the fundamental features of the software. Performance Testing allows keeping your users happy. Helps to identify the loopholes which make the system work less efficiently.

A process to check the system accepts the requirements of a user or not. It's performed at a time when the system used by actual users. Load Tests The action of the system under average load, containing the expected no.

of concurrent users doing a particular number of transactions within an average hour. Measure system capacity, and know the actual maximum load of the system while it still meets performance goals.

Peak Load Tests Understand system behavior under the most massive demand anticipated for the concurrent number of users. Endurance Soak Tests Endurance testing determines the longevity of components, and if the system can withstand average to peak load over a predefined duration.

Memory utilization should be observed to detect potential failures. The testing will also measure that throughput and response times after sustained activity continues to meet performance goals. Stress Tests Under stress testing, several activities to overload the existing resources with excess jobs are carried out in an attempt to break down the system.

Understand the upper limits of capacity inside the system by purposely pushing it to its breaking point. The goal of stress testing is to ascertain the failure of the system and to observe how the system recovers back gracefully.

The challenge is to set up a private environment before launching the test so that you can precisely capture the behavior of the system repeatedly under the most unpredictable scenarios.

Performance tuning improves the price to performance ratio for a system or set of services by reallocating the available computing, network, or storage resources.

Raw data is useful, but interpretation is key. Remember the objectives you identified before getting started? Analyze those metrics in your dashboards, as well as bottlenecks, spikes, or any irregular patterns that could indicate a performance issue. Once identified, these become targets for optimization in your next development cycle.

Collaboration is the backbone of agile performance testing. The goal is to align everyone involved — developers, testers, DevOps, and product managers — on performance requirements and results. Effective collaboration drives expedited time-to-market and results in more satisfied and productive teams.

Usually, collaboration includes regular sync-ups, shared documentation, and collective decision-making, but find the methods that work for you. Each testing cycle provides valuable data that should be used to optimize and refactor the code and the testing procedures.

If a test reveals a bottleneck, fix it and then retest to confirm the fix worked. The same iterative approach applies to the testing process itself.

Maybe you find that certain tests are redundant, or perhaps new features require new types of performance tests. Adapt the test suite accordingly. Agile performance testing is not a one-off task. These will ensure your organization truly benefits from agile performance testing and can consistently and continuously identify issues on time.

Above all, be flexible and adaptable. The agile environment is constantly changing, so it is important for performance testers to be flexible and adaptable as well.

This means being willing to change test plans, objectives, and test cases as needed. By keeping agile performance testing a top priority, organizations can ensure their products are of the highest quality and help them stay competitive in their field. Start Testing Now.

First, don't test your application on a large scale without actually needing to do so. Sure, it's always good to produce higher traffic loads than expected to stay on the safe side, but to be realistic and productive, you should focus on evaluating the right workload that your app will experience in production.

Of course, your website or app may experience demand during more than one peak or spike load time depending on seasonal events unique to your industry.

The keyword here is throughput, which is another commonly misunderstood performance testing topic. Be sure to check out my post, Performance Testing Basics What is Throughput to learn more.

Spend some time getting this step right since it is the fundamental cornerstone to creating proper load tests. Make sure your load generators are ready to sustain a workload.

This is usually done by emulating browsers communicating with the backend of your system. It's not enough just to create a test that will mimic real-world scenarios.

You also need to ensure that your scripts are not overloading the test tool itself. Make sure you have optimized the settings for your test scenario. Take any hardcoded or dynamic data that needs to be parameterized into consideration. You don't want to code a test that generate unrealistic failures because of a poorly written script or improper correlation.

Be sure to generate the right amount of data, which will enable successful tests at the end of the day. All tools should have some logic of how to add think time by specifying how many seconds you want the virtual user to wait.

Think time is useful to mimic the right workload according to the real behavior of the virtual user. Just like a functional Selenium test, it's also advised to use think time rather than a sleep function.

People either forget to add them or else they use two milliseconds. You really need to create a realistic performance test scenario that emulates how a real user is going to interact with your product.

Is it going to take a minute to perform this task? This can also cause people to create unrealistic results that aren't valid, which will, in turn, cause the team to panic for no reason, so avoid this mistake at all costs. It's probably unnatural for an application to get so many virtual users logging in at the same time and out at the same time.

If you can afford to make the ramp-up and ramp-down time longer, then do so.

Performance testing is a non-functional software test used to evaluate how well an application performs. In particular, performance testing aims to evaluate a number of metrics such as browser, page, and network response times, server request processing times, number of acceptable simultaneous users, CPU memory consumption, and the number and type of errors that arise when the application is being used. Whether it is a retail websites or a business-orientated SaaS solution, performance testing plays an indispensable role in enabling organizations to develop high-quality digital services that provide reliable and smooth service required for a positive user experience.
