In a DAW(Digital Audio Workstation), this is like adjusting the knobs, adding effects when you haven't even added any samples, it just doesn't make any sense, stop forcing yourself to do things that doesn't align with your flow, you'll likely get annoyed for no reason.
The way I work is I do the architecture design, I write the code, then I write my test by following the design graph.
If I don't know what the design would look like, I do what I call "code freestyling" to get a basic idea of what the overall design would look like then I repeat the above step.
