Add test harness for macro crate #530
Description
Description
Description
We currently have no testing mechanism for the macro crate.
Probably best to have this before #489 and #527 is merged.
Example
https://crates.io/crates/runtime-macros is recommended by tarpaulin
This can probably used together with https://docs.rs/macrotest/latest/macrotest/ to also test that the output matches.
Additional Context
- I can try implementing this feature myself (please assign me to this issue)
