JS Injector

Automate testing and auto-populate forms by injecting javascript code into the page. If [Run in isolation] is checked, the injected script will not contaminate the original code.

JS Injector Chrome Extension

JS Injector enables automation of web testing and form filling by injecting custom JavaScript directly into web pages. You can add popular libraries like jQuery, specify target pages using URL matching including fuzzy patterns, and choose to run scripts in isolation to avoid altering original page code or allow interaction when needed.

Its core features include seamless integration of existing JS libraries, precise targeting of web pages for script injection, and flexible isolation modes to protect or interact with native page scripts. This extension is ideal for developers aiming to streamline their testing workflows and auto-populate forms efficiently without modifying original site code.
