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

So you're suggesting when I want to debug my class I change this:
  class mySerialPort : public QSerialPort {};
to
  class mySerialPort : public virtualSerialPort {};
and recompile (where virtualSerialPort inherits from a QIODevice that I customize to do what I need to do)?

Basically the features I need are:
1. I need to be able to inject a QByteArray into the class and have that emit the readyRead() signal
2. The readyRead() signal is connected to my parse() slot
3. in parse(), I need myClass::readAll() to come back with that same QByteArray that I injected in step #1

It looks like maybe QBuffer (which I didn’t know existed) might be close to what I need... Ideally I was hoping to do it in a way that I didn't have to change any of the code of my serial port class, just to make sure I'm not introducing an error during this process...
