We’re excited to announce that the WebXPRT 5 Preview is now available!

The Preview is available to everyone. You can access it at www.WebXPRT5.com or through a link on WebXPRT.com.

You are free to publish scores from testing with this Preview build; in fact, we encourage it. We want to know how it is performing for you, so we love to see both test scores and any feedback you would like to give.

We may still tweak a few things in the benchmark between this Preview and the final release. We plan to limit any potential changes, however, to areas like the UI and other features, things we do not expect to affect test scores.

Longtime WebXPRT users will notice that while the WebXPRT 5 Preview UI has a new look and feel, the basic layout has not changed. The general process for kicking off both manual and automated tests is the same as with WebXPRT 4, so the transition from WebXPRT 4 to WebXPRT 5 testing should be straightforward.

We also encourage you to check out our recent XPRT blog post on the WebXPRT 5 workload lineup for more details about what’s new in the Preview release—including more AI-oriented scenarios than ever before!

After you try the WebXPRT 5 Preview, please send us your comments. Thanks, and happy testing!

How to automate your WebXPRT 4 testing

Justin Greene
By Justin Greene
on August 22, 2024

We’re excited about the ongoing upward trend in the number of completed WebXPRT 4 runs that we’re seeing each month. OEM and tech press labs are responsible for a significant amount of that growth, and many of them use WebXPRT’s automation features to complete large blocks of hands-off testing at one time. We realize that many new WebXPRT users may be unfamiliar with the benchmark’s automation tools, so we decided to provide a quick guide to WebXPRT automation in today’s blog. Whether you’re testing one or 1,000 devices, the instructions below can help save you some time.

WebXPRT 4 allows users to run scripts in an automated fashion and control test execution by appending parameters and values to the WebXPRT URL. Three parameters are available:

  • test type
  • test scenarios
  • results

Below, you’ll find a description of those parameters and instructions for how you can use them to automate your test runs.

Test type

The WebXPRT automation framework accounts for two test types: (1) the six core workloads, and (2) any experimental workloads we might add in future builds. There are currently no experimental tests in WebXPRT 4, so always set the test type variable to 1.

  • Core tests: 1

Test scenario

The test scenario parameter lets you specify which subtest workloads to run by using the following codes:

  • Photo enhancement: 1
  • Organize album using AI: 2
  • Stock option pricing: 4
  • Encrypt notes and OCR scan using WASM: 8
  • Sales graphs: 16
  • Online homework: 32

To run a single subtest workload, use its code. To run multiple workloads, use the sum of their codes. For example, to run Stock options pricing (4) and Encrypt notes and OCR scan (8), use the sum of 12. To run all core tests, use 63, the sum of all the individual test codes (1 + 2 + 4 + 8 + 16 + 32 = 63).

Results format

The results format parameter lets you select the format of the results:

  • Display the result as an HTML table: 1
  • Display the result as XML: 2
  • Display the result as CSV: 3
  • Download the result as CSV: 4

To use the automation feature, start with the URL https://www.principledtechnologies.com/benchmarkxprt/webxprt/2021/wx4_build_3_7_3, append a question mark (?), and add the parameters and values separated by ampersands (&). For example, to run all the core tests and download the results, you would use the following URL: https://principledtechnologies.com/benchmarkxprt/webxprt/2021/wx4_build_3_7_3/auto.php?testtype=1&tests=63&result=4

We hope WebXPRT 4’s automation features will make testing easier for you. If you have any questions about WebXPRT or the automation process, please feel free to ask!

WebXPRT’s mirror host site in Singapore

Justin Greene
By Justin Greene
on May 25, 2023

If you’ve ever spent time exploring WebXPRT.com, you may have noticed a line that says, “If you are in East Asia, you can run WebXPRT from our Singapore host,” followed by a hyperlink with Simplified Chinese characters. We realize that some people may not know why we have a WebXPRT mirror host site in Singapore—or how to use it—so today’s post will cover the basics.

When we first released WebXPRT 2013, some users in mainland China reported slow download times when running the benchmark. These slowdowns affected initial page and workload content load times, but not workload execution, which happens locally. As a result, subtest and overall scores were still consistent with expectations for the devices under test, but it took longer than normal for test runs to complete. In response, we set up a mirror host site in Singapore to facilitate WebXPRT testing in China and other East Asian countries. We continued this practice with subsequent WebXPRT versions, and currently offer Singapore-based instances of WebXPRT 4, WebXPRT 3, and WebXPRT 2015.

The default UI language on the Singapore site is Simplified Chinese, but users can opt to change the language to English or German. Apart from a different default language, the WebXPRT mirror instances hosted in Singapore are identical to the instances on the main WebXPRT site. If you test a device on WebXPRT Singapore and WebXPRT.com, you should see similar performance scores from both sites.

We hope that the WebXPRT mirror host site in Singapore will make it easier for people in East Asia to use the benchmark. Do you find the site useful? If so, we’d love to hear from you! Also, if you encounter any unexpected issues or interruptions while testing, please let us know!

We want your thoughts about experimental WebXPRT 4 workloads

Justin Greene
By Justin Greene
on December 8, 2022

Two weeks ago, we discussed how users can automate WebXPRT 4 testing by appending several parameters and values to the benchmark’s URL. One of these lets you enable any available experimental workloads during the test run. While we don’t currently offer any experimental workloads for WebXPRT 4, we are seeking suggestions for possible future workload scenarios, or specific web technologies that you’d like to be able to test with an experimental workload.

The main purpose of optional, experimental workloads would be to test cutting-edge browser technologies or new use cases, even if the experimental workload doesn’t work on all browsers or devices. The individual scores for the experimental workloads would stand alone, and would not factor in the WebXPRT 4 overall score. WebXPRT 4 testers would be able to run the experimental workloads one of two ways: by adjusting a value in the WebXPRT 4 automation scripts, as mentioned above, or by manually selecting them on the benchmark’s home screen.

Testers would benefit from experimental workloads by learning how well certain browsers or systems handle new tasks (e.g., new web apps or AI capabilities). We would benefit from fielding workloads for large-scale testing and user feedback before we commit to including them as core WebXPRT workloads.

Do you have any general thoughts about experimental workloads for browser performance testing, or any specific workloads that you’d like us to consider? Please let us know.

As the number of WebXPRT runs continues to grow, we realize many new WebXPRT users may be unfamiliar with all the features and capabilities of the benchmark. To help inform users about features that might facilitate their testing, we’ve decided to highlight a few WebXPRT features here in the blog. A few weeks ago, we discussed the multiple language options available in the WebXPRT 4 UI. This week, we look at WebXPRT 4 test automation.

WebXPRT 4 allows users to run scripts in an automated fashion. You can control the execution of WebXPRT 4 by appending parameters and values to the WebXPRT URL. Three parameters are available: testtype, tests, and result. Below, you’ll find a description of those parameters and instructions for utilizing automation.

This parameter lets you select the format of the results:

  • Display the result as an HTML table: 1
  • Display the result as XML: 2
  • Display the result as CSV: 3
  • Download the result as CSV: 4

To use the automation feature, start with the URL http://www.principledtechnologies.com/benchmarkxprt/webxprt/2021/wx4_build_3_7_3, append a question mark (?), and add the parameters and values separated by ampersands (&). For example, to run all the core tests and download the results, you would use the following URL: http://principledtechnologies.com/benchmarkxprt/webxprt/2021/wx4_build_3_7_3/auto.php?testtype=1&tests=63&result=4

We hope the WebXPRT automation features will make testing easier for you. If you have any questions about WebXPRT or the automation process, please feel free to ask!

The Exploring WebXPRT 4 white paper is now available

Justin Greene
By Justin Greene
on September 1, 2022

This week, we published the Exploring WebXPRT 4 white paper. It describes the design and structure of WebXPRT 4, including detailed information about the benchmark’s harness, HTML5 and WebAssembly (WASM) capability checks, and changes we’ve made to the structure of the performance test workloads. We explain the benchmark’s scoring methodology, how to automate tests, and how to submit results for publication. The white paper also includes information about the third-party functions and libraries that WebXPRT 4 uses during the HTML5 and WASM capability checks and performance workloads.

The Exploring WebXPRT 4 white paper promotes the high level of transparency and disclosure that is a core value of the BenchmarkXPRT Development Community. We’ve always believed that transparency builds trust, and trust is essential for a healthy benchmarking community. That’s why we involve community members in the benchmark development process and disclose how we build our benchmarks and how they work.

You can find the paper on WebXPRT.com and our XPRT white papers page. If you have any questions about WebXPRT 4, please let us know, and be sure to check out our other XPRT white papers.
