Performance testing for web applications -

The results of the test are recorded and documented. Benchmarking is a bit different. Benchmark tests essentially compares performance of an application against other applications or an industry standard to ensure it meets or exceeds quality stands.

This is especially important for organizations looking to set quality standards or meet specific service-level agreements SLAs of their applications and software for their users and partners.

Benchmarking is very much driven by the business and organization, helping to provide trust with potential customers and showcases your organization as a leader in your space. As we previously described, performance testing consists of testing the non-functional aspects of a software application, like application behavior, usability, and reliability as well as understanding how the system responds and how resources are used.

The performance testing life cycle PTLC consists of different phases and strategies. Performance testing essentially begins where functional testing left off. The next step is to come up with the test strategy. This includes preparing the scope of the test, the workload models, and identifying the scenarios that will be tested.

In addition to that, teams will define the metrics that will be used to measure success, however, sometimes this will change once the tests are executed and data is reviewed.

This step consists of creating the test scripts and user actions that were defined in the test strategy. Next those scripts are prepared for performance testing against the agreed upon workload models.

Lastly, once the performance test has finished, performance engineers can view the test data and analyze the results and begin the process of making recommendations for improvements. Performance testing of your websites, web apps, and APIs is essential to the user experience.

Ensuring your sites and applications operate efficiently and quickly, even while under high amounts of traffic, is key to the generating revenue to support business objectives.

For example, websites or applications that load faster have better retention rates than page or applications that load slowly.

Visitors that encounter slow load pages will likely never revisit that site again. First impressions are everything, so obviously, there are many benefits to performance testing. While performance testing has many advantages, it does come with some drawbacks.

Not all teams and organizations are the same, so it may require more effort for some teams. However, many of the web-based performance testing tools in the market can help alleviate that issue.

Performance Testing Checklist Typically, once functional testing has been completed and the application is near the end of the software development life cycle, the next step is to test the application and functions under specific workloads to see how your application and underlying system responds.

In more Agile development processes, performance testing is regularly completed to check performance throughout the development lifecycle, so by the time the application reaches the end of development, most of the bottlenecks and issues have been addressed. To help assist with the performance testing process, creating a performance testing checklist can help to define the steps and scenarios that need to be carried out and to help you to better follow your plan.

The benefit of documenting your checklist serves many purposes, like keeping the test plan on track, but it also allows you to modify and include additional procedures and considerations that come up during the testing process itself. The performance testing checklist can also serve as validation for clients, so you can show them firsthand and walk them through the detailed plan you have put into place, which can help build more trust, provide added value, and validate the entire process.

Production Environment vs. As development cycles became shorter, it pushed performance testing to start sooner. performance of until your application or site was pushed live. Setting up a test environment, also called a sandbox, allows development teams to carry out testing without affecting the production, or live environment.

While setting up a duplicate environment does add additional cost and resources, it greatly reduces the risk of unexpected issues arising in the production environment. For example, executing load tests on your website in the live environment could inadvertently cause your test to become a stress test and cause the site to crash.

Now, there are some situations where testing is production is ok, but those should best be executed when traffic to your website is light to minimize the impact to users. These reports, dashboards, and metrics are what are used to understand where bottlenecks exist and what system enhancements are needed to boost your websites, applications, and APIs.

Although reports vary for the various performance testing solutions, and some elements may be called out differently, there are still some core performance metrics that need to be inspected and scrutinized in the performance testing reports.

Additionally, most tools allow you to easily share these reports with others, so you can receive and gather feedback from various departments. If not, it may just add more confusion and require you to go back to the beginning and reassess your performance tests. One of the most important visuals that performance testing tools create is the waterfall chart.

For example, one of the most important performance testing metrics to watch for is load time. Remember, visitors are more likely to abandon your pages if the page load time is too slow.

In your performance testing requirements plan, if you required your website to load under 3 seconds under the specified user load, the reports will show you that, along with all load and response times of the individual components. Along with the waterfall chart that displays load times, response times, and file sizes of all the elements that make up your web page, users will typically be provided with additional metrics and dashboards that display errors, such as HTTP error codes, or possibly completion timeout errors if elements take too long to load.

Additional visuals and reports include showing the performance testing execution plan, where you can see how the number of virtual users over the test period affects response times. You can compare that data with the waterfall chart to better understand which specific components could be hindering performance.

Another important graphic is the cumulative session count. Performance engineering is one of the most complex and demanding positions within DevOps teams. The people within these positions typically have a combination of skillsets, as these jobs require knowledge about the entire software development life cycle, including performance testing, scripting, UI, systems engineering, etc.

A good performance engineer will not only be able to understand how to build a successful product, but also understand the business requirements, so that the product is developed with best practices and industry standards in mind.

The way applications are developed today and completely different than the process was just a decade ago. Development life cycles have become shorter and shorter, partly due to meet user demands, but also to implementing new software development strategies.

The performance engineering methodologies and practices are aligned with the Agile process and shift-left testing. Performance engineers are also responsible for suggesting to business stakeholders where and when investments in infrastructure and capacity need to be made, as well as continually tuning and monitoring the system.

Are you looking for a career as a performance testing engineer? If so, here are some of the top performance testing interview questions you may be asked. Use these as a guideline for the interview process to prep yourself for what you may be asked.

Performance testing can be a complex and time-consuming process, but with the right planning and performance testing tool, it can become easier and more repeatable. Performance testing is a critical step in the software development life cycle. It reduces the risk of deploying an application that could become unstable under heavy load and give users a negative experience.

Below are some frequently asked questions and answers to performance testing. Table of Contents. A stress test is a type of performance test that aims to push a system, an application, or website by continually increasing the number of simultaneous users until a point where performance starts to degrade, even to the point of failure.

Stress testing is done to show where the breaking point of a system is, at what point resources are fully consume, and how system responds and recovers.

Conversely, load tests use a pre-defined load to gauge performance and behavior of a system, set performance baselines, and plan for capacity. Load tests are not designed to intentionally push the application or system to failure.

How do you test website performance online? Testing website performance can be done a couple of different ways.

One way is to run a website speed test on your key web pages. There are a lot of free website speed test tools that developers and web designers can access to run a quick speed test to quickly see which on page elements may be impacting load times.

The great thing about these website speed test tools is that they typically include multiple test servers, so you can pick and choose which locations best meet where your visitors come from. The other way to test your website performance is running performance testing.

Performance tests can take website speed tests to the next level by simulating hundreds or thousands of users accessing your website over a given timeframe. Performance tests will uncover bottlenecks, such as CPU, memory, and network issues that arise when pushed to the limits.

How does performance testing differ from load testing? Performance testing is a form of non-functional testing that includes a subset of multiple testing types, including load testing, stress testing, spike testing, endurance testing, scalability testing, and volume testing.

All these performance testing types seek to determine various aspects and metrics as load is put onto the system. Performance testing tools can come in a variety of flavors, including on-premises, cloud-based, or in some cases, both. One of the advantages of on-premises tools is that you have total control over the testing environment, however, that means additional resources to setup test environments.

Cloud-based performance testing tools allow developers to get up and running, as the test environment is completely managed by the provider. Functional testing is a type of software testing that is performed by QA engineers and teams.

Functional testing is carried out to find if specific functions work or not. For example, one method of functional testing for applications can be if a user can navigate through specific pages without issue. Within the software development life cycle, functional testing is carried out before performance testing.

You have to ensure your software works before you start performance testing or results are going to be skewed. How is acceptance testing performed on websites?

User acceptance testing, or UAT testing, is the last stop in the software development cycle before the website is officially released. Acceptance testing is the final review to ensure that a website functions properly and that it meets all the pre-defined requirements for your users or your clients, as well as the business.

If any errors are found, development teams can work with QA to resolve them before the final deadline. UAT testing is typically performed manually by groups of testers, although, it can be automated based on a series of scripts. Once the application or website is ready for UAT testing, various real-world scenarios should be defined that users can go through.

For example, if you manage an e-commerce website, you could individually test different payment options, and their associated steps, to ensure a seamless process. Software performance testing is the process of determining the performance, availability, and scalability of a software under a pre-defined workload.

Types of software performance testing include load testing, stress testing, spike testing, and endurance testing and are usually carried out right after functional testing has been completed.

How does software performance testing differ from website performance testing? The differences between software performance testing and website performance testing are not all that different. It really comes down to their definitions.

A website is a collection of web pages that can be accessed over the Internet via a browser. A software is a program or application that can run in a browser and accessed through web pages.

Another way to think about it is that web pages are typically static and informational, where web applications tend to be interactive.

However, you may get a different explanation depending on who you ask as the lines between them are blurred.

How do you calculate the number of users in performance testing? One way is to review website analytics tools, like Google Analytics, view visitors and visitor breakdowns by hour, day, or weekly visits.

With these factors, you can then calculate the concurrent users. To calculate the concurrent users, take your peak hourly visits and multiply that by the average visitor duration in seconds and then divide that by 60, the number of minutes in an hour.

How do you benchmark website performance? One way to do that is to run website speed test from different locations around the world, as this will better simulate the real-world experience and give you better data in return.

From there, you can use website monitoring tools to ensure your website is continually within these performance guidelines. What is response time in performance testing? In performance testing response time is the time it takes for a request to be sent and received.

For example, when you click on a button on a web page, the time it takes your request to be send and received by the server and completed is the response time. Response times will be displayed in waterfall charts and performance results. Some important metrics to follow in performance testing is average response time and maximum response time, so you can identify when elements are not performing as intended.

How is browser compatibility testing related to performance testing? Browser compatibility testing, also known as cross browser testing, is the process of testing whether a website or web application is compatible and performs within various browsers.

This is especially important for mobile devices, as user network speeds vary by location. What is the best performance testing automation framework? Test automation frameworks are beneficial for developers as they can allow the ability to automate and reuse code for testing purposes, removing the necessity to spend time to create redundant tests, as well as associated costs that go along with that.

This allows teams to more quickly and efficiently test their code, making testing cycles shorter. There are different types of automation tools. Some of the most popular test automation frameworks are Cucumber, Selenium, Appium, and Cyprus. However, one of the best performance testing automation frameworks is Jenkins.

Jenkins is an open-source automation server that give developers the ability to build, test, and deploy their software applications. What is the best performance testing tool? The best performance testing tool is LoadView. LoadView provides several performance testing options, such as websites, APIs, web applications, and streaming media.

The solution can perform protocol-based tests, as well as real browser-based testing. For web applications, the tool comes with a point and click scripting tool, called the EveryStep Web Recorder, which supports all the popular web technologies and frameworks, making creating scripts for user scenarios a breeze.

Set Up Your Testing Environment This step is paramount. Configure the Environment Before plunging into tests, invest time in fine-tuning the environment. Hybrid load testing is a combination of protocol-based and browser-based load testing.

While you can use two tools or two scripts to execute different types of load testing one protocol-based and one browser-based , having both types of tests executed by the same script and the same load testing tool is ideal. Aggregating results between different tools can be difficult at best and inconsistent at worst.

A best practice in hybrid load testing is to generate most of the load using the protocol-level test, and then to run a smaller number of the browser-level testing scripts. This approach:. Record your user journey. Using the browser recorder can facilitate initial test script creation by capturing all the embedded resources on webpages.

Check out the session recording guide to learn more about how to auto-generate your load test from a user session. Correlate data. Go through the recorded requests and determine whether you need to extract values from previous responses and use parameters in subsequent requests.

This practice ensures your VUs behave more like real users would. Include or exclude static resources. Determine whether you should include or exclude static resources on pages such as images, JavaScript, etc.

Consider including them if you want to measure overall user experience. Consider excluding them if you are using a Content Delivery Network CDN that is under a separate Service Level Agreement SLA.

Exclude third-party requests. Many applications make calls to third-party providers for authentication, social sharing, and marketing analytics. Disable these requests unless you have permission to include them in your tests.

Use concurrent requests. To mimic the way modern browsers download some requests in parallel, use batching. Determine cache and cookie behavior.

k6 automatically resets cookies between iterations, but you can also change this behavior if maintaining cookies would be more realistic. Use dynamic think time and pacing. Use test data.

Consider adding a test data file for the script to iterate through. Model test parameters and load profile after production. In k6, you can use test options to determine the exact shape and profile of your load test script. Select the appropriate executors for the job. Use tags and groups. Organizing requests by tagging and grouping them helps you consolidate like metrics and makes your test scripts more understandable by others.

Use scenarios. When combining protocol-based and browser-based tests, use scenarios to independently control their test parameters and executors. Modularize scripts. Use modules to separate and organize functions for protocol-level testing and browser-level testing, and then use a test runner script to execute them.

This approach means different scripts can be versioned and changed without affecting each other. Integrate your tests into your CI pipeline. Create thresholds for both types of testing.

Set thresholds for relevant metrics from both the browser-level script and the protocol-level one. Use protocol-based scripts to generate majority of the load. When writing the test scenario, use the protocol-based requests to simulate most of the traffic and use fewer VUs for the browser-based requests.

Relying on the protocol-level traffic helps keep resource utilization on load generators down. Testing in pre-production environments staging, test, system integration testing, user acceptance testing, and production replica environments enables you to identify performance defects early, which can save a lot of time and effort and reputation later on.

Running in test environments also means you can often afford to be more aggressive with your tests. Often, testing production is the only feasible alternative.

You can reduce the risk of impact to real customers while testing in production by using lower levels of load when running load tests during peak hours, schedule tests for off-peak hours, choosing load test types that are less risky, using techniques like synthetic monitoring that generate less traffic, using real user monitoring tools to get snapshots of user performance at load, and ensuring that your observability stack is working at peak efficiency.

The location of the load generator s , where the traffic is coming from , can also have an impact on your test results.

The question is: Where are your end users located? On-premises load testing can be ideal when testing early on in the development a website, or when there are machines that can be repurposed as load generators. However, testing entirely from within a corporate network may also yield false positives, in that response times reported are significantly lower than if the same application servers were accessed from across the country.

Load testing on the cloud is an essential part of the testing strategy for many public-facing websites. Cloud load generators are easier to provision and cheaper to maintain in the long run than on-premise ones.

Load testing on the cloud can help you include the effects of network latency in your tests and yield results that are more realistic. Here are some recommendations to help you plan, script, and execute your load tests for websites. Test in pre-production environments when you can, but also consider testing in production in a limited capacity.

Load testing websites can be complex due to the number of viable testing approaches available, the scope for performance testing, and the potential effects of releasing undertested code.
