fix: refactor tests (#1066)

## Changes Made

- Refactor/optimise tests
- Reduce flakiness
- Add parallel tests (if there's enough CPU capacity)
- Removed explicit worker count when running parallel tests. Defaults to
50% of CPU capacity.

Might want to consider sharding the test across runners in the future as
our tests grows.
