If you’re a current k6 customer or just searching for a performance testing solution for your organization, you may want to take a look at LoadView by Dotcom-Monitor. Creating load and stress tests for your websites, web-apps, and APIs has never been easier. Read more about the powerful features and functionality of LoadView below.

As user and customer expectations become more demanding, the technology used to build websites and web applications becomes increasingly complex. Developers and engineers have to ensure these complex systems don’t deter users or impact performance. In fact, studies show that if your website doesn’t load within just a few seconds, users are likely to abandon it completely, and likely never to return. In order to avoid losing a potential customer to your competition, organizations need to execute performance testing to ensure websites and applications are performing within specific thresholds, ensuring that the customer experience is seamless.

k6 is a solid performance testing solution for DevOps and engineers. And while there are definitely some similarities between the LoadView and k6, we’ll dive into how LoadView sets itself apart from other load testing platforms.



LoadView versus k6: Load Testing for Websites, Web Applications, and APIs

The LoadView platform was created with performance and usability in mind. LoadView utilizes fully managed cloud networks, so there’s no need to mess with setting up load generators, creating global agents, or worrying about maintaining any additional infrastructure. By removing these time-consuming tasks from the performance testing setup process, developers and engineers can manage their time more effectively by designing, executing, and analyzing their tests.

Determining how many users your site, application, or API can handle, and how your systems respond, is important for various reasons, but there are several significant scenarios why load and stress testing are vital:

  • Infrastructure

Determining if upgrades are needed.  The cost of implementing additional hardware/software could be a potential waste of resources.

  • Scalability

Understanding why your site or application slows down when multiple users access it

  • Production Environment

Your site or application can handle a few users without concerns, but what happens in real-world situations?

  • Third-party Services

See how external services behave during normal or peak load conditions

k6 helps to simplify load testing for DevOps teams by integrating with automation and Continuous Integration (CI) tools, such as Jenkins, Circle CI, Team City, GitLab, and Azure Pipelines. The platform makes performance testing available throughout the development cycle, uncovering issues earlier in the development process. For APIs, k6 uses Postman for functional testing. Users have to export their Postman collections and convert them into JavaScript scripts in order to run load tests.


Scripting: The EveryStep Web Recorder Versus k6

The EveryStep Web Recorder is a free scripting tool that records and each step of a transaction and replays the script using a real browser. The EveryStep Web Recorder is web-based and there are no additional plugins or downloads. It’s easy to use and there is no scripting experience required. In fact, someone who has never had experience running a load test can setup and execute a load test within minutes.

Users can record multi-step test scripts of the critical actions your users take while navigating your web pages, such as button clicks, menu selections, form submissions, shopping carts, and text inputs. These scripts can then be uploaded into the LoadView platform for load testing. Scripts can be recorded to test compatibility on 40+ desktop/mobile browsers and devices and supports nearly anything that can be rendered in a browser, including many popular languages/technologies such as Flash, Java, HTML5, PHP, Silverlight, AJAX, Ruby, and many more.

Unlike the EveryStep Web Recorder, the k6 test scripts utilize the ES6 JavaScript command line interface, so knowledge of JavaScript language is required, which, depending on your team’s skills, may require a higher learning curve. Due to this limitation, k6 does not run in a browser, therefore, will not render web pages like a real browser would. Also, k6 does not run NodeJS, however, users have a workaround to import npm modules (with browserify or webpack) or libraries utilizing a NodeJS API for tests.

Users can also choose to script manually or use the k6 HAR converter. All modern browsers are able to export a HAR file. This functionality allows k6 users to go to a web page and browse like an actual user would. That HAR file can then be exported and converted right from the command line. There is also a k6 Chrome Extension that users can download that essentially does the same thing by creating a HAR file and using the same conversion operation.

Additionally, developers can run smaller load tests from on-premises machines and from behind a firewall, giving developers the ability to run regular load tests as part of their automated CI process to uncover bugs or get quick performance baselines prior to moving code into staging or production environments. Additional features of k6 include:

  • Support for HTTP/S and WebSockets protocols
  • Users can generate random numbers and parameterize data
  • Scripts can become custom modules for common actions to share

These additional steps and downloads aren’t necessary with the EveryStep Web Recorder, as everything is already recorded from the browser, and users don’t have to work from a command line interface, saving you valuable time. Also, k6 does not support RIA’s, such as Flash, Silverlight, Java, HTML5, PHP, and Ruby. And lastly, load testing a mobile site or application requires users to use an actual device, which means another myriad of steps and requirements. With the EveryStep Web Recorder, you can choose from a the most popular mobile browsers and devices, no additional steps or requirements necessary.


Executing a Load Test: LoadView versus k6

Many open-source load testing solutions will only run protocol-based user simulations, which is not enough. It’s fine for testing the server at the protocol level, but you’d be missing the end-to-end client-side response times.  This is critical when it comes to testing web applications. LoadView users have the option to run the following user simulation options:  HTTP/S and real browser-based tests. And to give users more customization and flexibility, and depending on your specific load testing needs, LoadView also provides several load type options for your test:

  • Load Step Curve

Useful when determining if your website can handle a spike in traffic. Generates loads with a pre-determined number of concurrent users for specified time durations.

  • Goal-based Curve

Beneficial for validating SLA or non-functional requirements. This test is useful when you have already identified the limiting level of your required throughput and need to ensure that your performance goal is met.

  • Dynamic Adjustable Curve

Allows users to adjust load and see results in real-time, giving users insight into how their site or application changes as load levels fluctuate.

k6 can also simulate protocol and real browser-based tests, and you can define your ramp pattern, but users don’t have the option to adjust load up or down during a test, as you can do with LoadView. And the k6 tests must be configured within the command line, there’s no interface to just point, click, and select from various options to customize your test like users can do with LoadView.


Generate User Traffic from Around the World

Once you’ve determined the load type, number of virtual users, and defined your scenario, one of the final steps is to decide where you’re going to test from. LoadView gives users the option to distribute user load between geographic locations. LoadView uses Amazon Web Services (AWS) and Google Cloud Platform (GCP) servers in 13 worldwide locations to generate virtual users. if you know that a certain percentage of your customers come from a specific geographic location, you can select those specific zones to test from to see how your websites and applications perform.

k6 users can move scripts to run on their global cloud infrastructure, allowing for much larger load tests, up 5,000 virtual users, to be run later in the development and QA cycles. Like the LoadView platform, this is managed for users, so there’s no need to create or manage separate cloud accounts. Choose from one of 14 load zones located across the world. However, if you need additional virtual users, k6 offers multiple add-on packages. With LoadView, this isn’t necessary, as you pay for only what you need and use.

LoadView versus k6: Conclusion

There are a lot of considerations to make when choosing k6 as your performance testing solution. Every k6 test must be built from a JavaScript file within their scripting tool, so depending on you or your team’s level of experience, there may be a steep learning curve involved due to this factor. Also, from a performance perspective, this means that k6 doesn’t render web pagers the same way as an actual browser does. Additionally, the k6 base package can only scale up to 5,000 virtual users. If you need anything beyond that, you must purchase set add-on packages. With LoadView, you don’t have to worry about that.

Creating scripts with the EveryStep Web Recorder is easy. All you do is point and click as a user would. The ability to run and test multiple user simulation types – all from a single platform – makes LoadView a more powerful load testing tool. And with no contracts and pay-as-you go pricing, LoadView gives organizations the ability to load and stress test their websites, web applications, web service, and APIs, on-demand, ensuring you can meet the needs of your customers and maintain a consistent user experience.
