[Interest] Is there a way to simulate serial port data?

I want to inject known data  into this class as if it's actually coming across the serial port to validate my parsing code, is there any way to do that? Ideally I'd be able to write data in and have it trigger the readyRead() signal, but I'm not seeing any way to do that.

Hi,

What about writing a “virtual serial port” ?

QSerialPort is a QIODevice, so one thing you can do is to replace it with a custom QIODevice where you can write what you from e.g. a “console widget” to evaluate what you want from your application.

Cheers
