What is single page application testing?
Last modified on August 05, 2021. A single-page application (also known as SPA) is a web application that uses one URL for all its screens.

In this blog post, we present how we measure performance of single-page applications at LinkedIn using RUM, and how we used RUM data to make our new LinkedIn web application faster by 20%. Page Load Time (PLT) is the key metric that we measure for every page at LinkedIn in order to capture the user’s perception of when the page is ready.
