Shifting Performance Testing Left with Sauce Performance

In this blog post, Abigail Kurtzman reviews the benefits of adding a front-end performance testing tool to your testing environment, including getting faster feedback from your tests much earlier in the pipeline.


Shifting testing left as part of your overall test automation strategy just makes sense. Running unit and functional tests early and often in the development cycle pays dividends by allowing teams to capture the root causes of bottlenecks and congestion much earlier in the process—so issues are easier and less expensive to fix. However, front-end performance testing often tends to be an afterthought.

Performance testing on the front end is typically not performed at all, and if it is, it’s limited to third-party load/stress testing or application performance monitoring (APM) solutions. This means teams are putting time and effort into maintaining separate tools and test suites that provide a limited view of the user experience once the application goes live. What a hassle! 

Adding a front-end performance testing tool to your testing environment can give your team the opportunity to get faster feedback from your tests much earlier in the pipeline. With Sauce Performance, you can get the benefit of front-end performance testing within the Sauce Labs platform you’re already using. Here are a few advantages of using Sauce Performance:

  • Gives a unified quality signal for testers with a single pane of glass for test results and feedback

  • Uses machine learning algorithm defined baselines to derive performance baselines and provide notification when true front-end performance regressions occur, helping teams remediate faster

  • Helps improve developer productivity by allowing teams to leverage existing Selenium test scripts to capture both functional and front-end performance data in a single test

We have a new Tech Talk video outlining how to use Sauce Performance to get insights on front end performance, along with some tips for how to get your tests up and running on our platform. Check it out here:
