[LRUG] Number of tests over time?

[Sam Phillips]

I've picked just one of ours (we have 30+). This is an API endpoint with no
UI. 3.5 years development, ~19 contributors overall, 3011 specs (of which
some are integration).

One discussion we have occasionally is the merit of removing unit tests
once the initial BDD/TDD is done and replacing with fewer, broader tests.
Like squashing git commits that made sense in the context of a branch but
years later don't mean anything, do small individual tests still give value
when coverage is available from wider specs? We've not deleted any yet
because everything is fast enough - eg the component above builds in 4
minutes.

I'd be interested if anyone else deletes tests later on.
