Code-less Performance Automation Testing: Browser Level Performance Testing — A thought

We all know that Codeless automation testing is a market trend now due to its many advantages. Being a performance tester, my thought always inclined toward codeless performance automation testing. In Feb 2022, I published a blog article ( in EuroSTAR Huddle, UK where I talked about how performance testing can be conducted in Low-code/ No-code development model.

Traditionally performance automation testing is always conducted at the protocol level. Later, when more and more heavy rich internet applications are deployed into production, knowing the actual end-user experience in the browser becomes crucial. Also, the accelerated release cycle via Agile, Dev-ops, and today’s low-code/no-code development creates an opportunity for faster performance automation testing. Browser level performance testing is the solution for both- it provides actual end-use experience and meets the objective accelerated release cycle.

Browser-level performance testing is not only faster performance testing, for me, it is also code-less performance automation testing. In this blog article, I will talk about why browser-level performance testing can be thought of as code-less performance automation testing.

Browser-level performance testing and traditional protocol-level performance testing:

Even though, in my earlier blogs ( ), I already talked about the difference between the browser-level and protocol-level performance testing. However, I still wanted to reiterate that for easy understanding. Protocol level performance testing is on server-side communications and browser level performance testing is on client-side communications. Browser rendering time is included in browser-level performance testing which is not in the case of protocol-level performance testing.

In protocol level performance testing, performance automation testing script creation requires a substantial amount of time (and most of its time is spent on correlation i.e., handling dynamically generated server-side values). Protocol level performance testing also requires good application knowledge as well as technical knowledge.

Browser-level performance test scripts are easy to create. Even maintaining browser-level performance test scripts is quite easy compared to protocol level due to having less complexity.

Codeless automation testing:

If we look at the codeless automation testing, it talks about minimizing testing time, reduced maintenance, record, and playback with minimized coding, even complicated test scenarios are easy to create and manage, a quick way to test, and require fewer programming skills.

Similarities between codeless automation testing and browser level performance testing:

Browser-level performance test scripts can be created easily, takes less time to create, easy and lower maintenance with record and playback mechanisms minimized coding, complicated web test scenarios are easy to create and manage and supports accelerated release cycle by conducting quick testing.

Thus, browser-level performance testing and codeless automation testing are quite similar in many ways. Browser-level performance testing assists in quick performance testing with ensuring end-user experience.


In a nutshell, browser-level performance testing can be thought like codeless performance automation testing looking at their similarities in many ways.
