Performance testing industry standards -

Implementing solutions early will less costly than major fixes at the end of software development. Adding processors, servers or memory simply adds to the cost without solving any problems. More efficient software will run better and avoid potential problems that can occur even when hardware is increased or upgraded.

Conducting performance testing in a test environment that is similar to the production environment is a performance testing best practice for a reason.

The differences between the elements can significantly affect system performance. It may not be possible to conduct performance testing in the exact production environment, but try to match:. Be careful about extrapolating results. Also, it works in the opposite direction.

Do not infer minimum performance and requirements based upon load testing. All assumptions should be verified through performance testing. Not every performance problem can be detected in one performance testing scenario.

But resources do limit the amount of testing that can happen. In the middle are a series of performance tests that target the riskiest situations and have the greatest impact on performance. Also, problems can arise outside of well-planned and well-designed performance testing.

Monitoring the production environment also can detect performance issues. While it is important to isolate functions for performance testing, the individual component test results do not add up to a system-wide assessment. But it may not be feasible to test all the functionalities of a system.

A complete-as-possible performance test must be designed using the resources available. But be aware of what has not been tested. If a given set of users does experience complications or performance issues, do not consider that a performance test for all users.

Use performance testing to make sure the platform and configurations work as expected. Lack of experience is not the only reason behind performance issues.

Mistakes are made — even by developers who have created issue-free software in the past. Many more variables come into play — especially when multiple concurrent users are in the system. Make sure the test automation is using the software in ways that real users would.

This is especially important when performance test parameters are changed. Performance and software testing can make or break your software. Before launching your application, make sure that it is fool-proof.

However, no system is ever perfect, but flaws and mistakes can be prevented. Testing is an efficient way of preventing your software from failing.

The performance tests you run will help ensure your software meets the expected levels of service and provide a positive user experience.

They will highlight improvements you should make to your applications relative to speed, stability, and scalability before they go into production. Applications released to the public in absence of testing might suffer from different types of problems that lead to a damaged brand reputation, in some cases, irrevocably.

The adoption, success, and productivity of applications depends directly on the proper implementation of performance testing.

While resolving production performance problems can be extremely expensive, the use of a continuous optimization performance testing strategy is key to the success of an effective overarching digital strategy. In each case, operational teams expose the application to end users of the product architecture during testing.

Development performance tests focus on components web services, microservices, APIs. The earlier the components of an application are tested, the sooner an anomaly can be detected and, usually, the lower the cost of rectification.

As the application starts to take shape, performance tests should become more and more extensive. There are many different types of performance tests. The most important ones include load, unit, stress, soak and spike tests.

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.

Unit testing simulates the transactional activity of a functional test campaign; the goal is to isolate transactions that could disrupt the system.

Stress testing evaluates the behavior of systems facing peak activity. These tests significantly and continuously increase the number of users during the testing period.

Soak testing increases the number of concurrent users and monitors the behavior of the system over a more extended period. The objective is to observe if intense and sustained activity over time shows a potential drop in performance levels, making excessive demands on the resources of the system.

Spike testing seeks to understand implications to the operation of systems when activity levels are above average. Unlike stress testing, spike testing takes into account the number of users and the complexity of actions performed hence the increase in several business processes generated.

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 problem s. The most common issues highlighted by performance tests are related to speed, response times, load times and scalability.

Excessive load time is the allotment required to start an application. Any delay should be as short as possible — a few seconds, at most, to offer the best possible user experience.

Poor response time is what elapses between a user entering information into an application and the response to that action. Long response times significantly reduce the interest of users in the application. Limited scalability represents a problem with the adaptability of an application to accommodate different numbers of users.

For instance, the application performs well with just a few concurrent users but deteriorates as user numbers increases.

Bottlenecks are obstructions in the system that decrease the overall performance of an application. They are usually caused by hardware problems or lousy code. While testing methodology can vary, there is still a generic framework you can use to address the specific purpose of your performance tests — which is ensuring that everything will work properly in a variety of circumstances as well as identifying weaknesses.

Comprehensive knowledge of this environment makes it easier to identify problems that testers may encounter. Before carrying out the tests, you must clearly define the success criteria for the application — as it will not always be the same for each project.

Identifying key scenarios and data points is essential for conducting tests as close to real conditions as possible:. This not only improves the application's performance but can also result in cost savings by optimizing resource usage. Identify bottlenecks: Performance testing can help identify the bottlenecks that are slowing down an application, such as inefficient database queries, slow network connections, or memory leaks.

Prevent revenue loss: Poor performance can directly impact revenue for businesses that rely heavily on their applications.

If an e-commerce site loads slowly or crashes during a peak shopping period, it can result in lost sales. Increase SEO ranking: Website speed is a factor in search engine rankings.

Websites that load quickly often rank higher in search engine results, leading to greater traffic and potential revenue. Prevent future performance issues: Performance testing allows issues to be caught and fixed before the application goes live.

This not only prevents potential user frustration but also saves time and money in troubleshooting and fixing issues after release. What makes performance testing for UI critical in modern apps? Challenges of performance testing A software's performance testing is critical for the entire SDLC, yet it has its challenges.

This performance testing guide highlights the primary complexities faced by organizations while executing performance tests: Identifying the right performance metrics: Performance testing is not just about measuring the speed of an application; it also involves other metrics such as throughput, response time, load time, and scalability.

Identifying the most relevant metrics for a specific application can be challenging. Simulating real-world scenarios: Creating a test environment that accurately simulates real-world conditions, such as varying network speeds, different user loads, or diverse device and browser types, is complex and requires careful planning and resources.

Deciphering test results: Interpreting the results of performance tests can be tricky, especially when dealing with large amounts of data or complex application structures.

It requires specialized knowledge and experience to understand and take suitable actions based on the results. Resource intensive: Performance testing can be time-consuming and resource-intensive, especially when testing large applications or systems.

This can often lead to delays in the development cycle. Establishing a baseline for performance: Determining an acceptable level of performance can be subjective and depends on several factors, such as user expectations, industry standards, and business objectives.

This makes establishing a baseline for performance a challenging task. Continuously changing technology: The frequent release of new technologies, tools, and practices makes it challenging to keep performance testing processes up-to-date and relevant.

Involvement of multiple stakeholders: Performance testing often involves multiple stakeholders, including developers, testers, system administrators, and business teams.

Coordinating between these groups and managing their expectations can be difficult. Also check: Performance Testing Challenges Faced by Enterprises and How to Overcome Them What are the types of performance tests?

Load testing: Load testing refers to a type of performance testing that involves testing a system's ability to handle a large number of simultaneous users or transactions. It measures the system's performance under heavy loads and helps identify the maximum operating capacity of the system and any bottlenecks in its performance.

Stress testing: This is a type of testing conducted to find out the stability of a system by pushing the system beyond its normal working conditions.

It helps to identify the system's breaking point and determine how it responds when pushed to its limits. Volume testing: Volume testing helps evaluate the system's performance under a large volume of data.

It helps to identify any bottlenecks in the system's performance when handling large amounts of data. Endurance testing: Endurance testing is conducted to measure the system's performance over an extended period of time. It helps to identify any performance issues that may arise over time and ensure that the system helps handle prolonged usage.

Spike testing: Spike testing is performed to measure the system's performance when subjected to sudden and unpredictable spikes in usage. It helps to identify any performance issues that arise when the system is subject to sudden changes in usage patterns.

Performance testing strategy Performance testing is an important part of any software development process. Read: Android vs. iOS App Performance Testing - How are These Different? What does an effective performance testing strategy look like? An effective performance testing strategy includes the following components: Goal definition: Testing and QA teams need to define what you aim to achieve with performance testing clearly.

This might include identifying bottlenecks, assessing system behavior under peak load, measuring response times, or validating system stability. Identification of key performance indicators KPIs : Enterprises need to identify the specific metrics they'll use to gauge system performance. These may include response time, throughput, CPU utilization, memory usage, and error rates.

Load profile determination: It is critical to understand and document the typical usage patterns of your system. This includes peak hours, number of concurrent users, transaction frequencies, data volumes, and user geography.

Test environment setup: Teams need to create a test environment that clones their production environment as closely as possible.

This includes hardware, software, network configurations, databases, and even the data itself. Test data preparation: Generating or acquiring representative data for testing is vital for effective performance testing. Consider all relevant variations in the data that could impact performance.

Test scenario development: Defining the actions that virtual users will take during testing. This might involve logging in, navigating the system, executing transactions, or running background tasks.

Performance test execution: After developing the test scenario, teams must prioritize choosing and using appropriate tools, such as load generators and performance monitors.

Results analysis: Analyzing the results of each test and identifying bottlenecks and performance issues enables enterprises to boost the performance test outcomes. This can involve evaluating how the system behaves under different loads and identifying the points at which performance degrades.

Tuning and optimization: Based on your analysis, QA and testing teams make necessary adjustments to the system, such as modifying configurations, adding resources, or rewriting inefficient code. Repeat testing: After making changes, it is necessary to repeat the tests to verify that the changes had the desired effect.

Reporting: Finally, creating a detailed report for your findings, including any identified issues and the steps taken to resolve them, helps summarize the testing efforts. This report should be understandable to both technical and non-technical stakeholders.

What are the critical KPIs Key Performance Indicators gauged in performance tests? Response time: This measures the amount of time it takes for an application to respond to a user's request.

It is used to determine if the system is performing promptly or if there are any potential bottlenecks. This could be measured in terms of how many milliseconds it takes for an application to respond or in terms of how many requests the application processes per second.

Throughput: This measures the amount of data that is processed by the system in a given period of time. It is used to identify any potential performance issues due to data overload. The data throughput measurement helps you identify any potential performance issues due to data overload and can help you make informed decisions about your data collection and processing strategies.

Error rate: This is the percentage of requests resulting in an error. It is used to identify any potential issues that may be causing errors and slowdowns. The error rate is one of the most important metrics for monitoring website performance and reliability and understanding why errors occur.

Load time: The load time is the amount of time it takes for a page or application to load. It is used to identify any potential issues that may be causing slow page load times. The load time is an important metric to monitor because it can indicate potential issues with your website or application.

Memory usage: This measures the amount of memory that the system is using. It is used to identify any potential issues related to memory usage that may be causing performance issues.

Network usage: This measures the amount of data that is being transferred over the network. It is used to identify any potential issues that may be causing slow network performance, such as a lack of bandwidth or a congested network. CPU usage: The CPU usage graph is a key indicator of the health of your application.

If the CPU usage starts to increase, this could indicate that there is a potential issue that is causing high CPU usage and impacting performance.

You should investigate and address any issues that may be causing high CPU usage. Latency: This measures the delay in communication between the user's action and the application's response to it. High latency can lead to a sluggish and frustrating user experience.

Request rate: This refers to the number of requests your application can handle per unit of time. This KPI is especially crucial for applications expecting high traffic. Session Duration: This conveys the average length of a user session. Longer sessions imply more engaged users, but they also indicate that users are having trouble finding what they need quickly.
