Plurrrr

We are excited to announce that native fuzzing is ready for beta testing in its development branch, dev.fuzz!

Fuzzing is a type of automated testing which continuously manipulates inputs to a program to find issues such as panics or bugs. These semi-random data mutations can discover new code coverage that existing unit tests may miss, and uncover edge case bugs which would otherwise go unnoticed. Since fuzzing can reach these edge cases, fuzz testing is particularly valuable for finding security exploits and vulnerabilities.

More and more websites are relying on JavaScript for the interactions they provide. It enables pleasant experiences but also comes with undesirable effects:

• Longer page load times
• Page is unusable until the JavaScript loads and if it does so without any errors
• Usability, reactivity and accessibility can be lacking without a team with the means and resources to pay attention to those.

Given these drawbacks, relying on solutions provided natively by browsers enables you to benefit at low cost from the expertise of the community creating web standards. These solutions generally have the advantage of using less code, thus reducing maintenance efforts for a development team (for example, no need to update the libraries used).

In this article, we will explore some of these native solutions that are available to the majority of your users. We will see some examples but we won’t go into all the subtleties, because other resources do so very well. Rather, the goal is to inform you of the existence of these techniques.
