Chromium-Native-Extension-Simulator

I use this simulator to do unary testing over a digital sign native application (multi platform). Simulating the browser allow me to identify bugs before integration. A particular annoying one arises from a I/O buffer on a MacOS terminal. Simulating the browser give me enough information to focus on the extension.

Chromium Native Extension Simulator for Native apps unit testing

This class was created with the aim of unit testing the I/O Mechanism between Chromium browsers and a java native app

• Instead of usign a browser, this class allows to programm specific flows in testing, and automate its execution.
• Synchronic communication is good enought in my case.
• Messages are encoded and decoded as 'utf-8' by default

Source Code

• ChromiumNativeExtensionSimulator.py contains the Python Class
• example.py is a test flow.
• echo-example-host.py responses the messages sent. Instead of calling this executable, the Native Application should be called (the same way it's done by the browser)
