Laravel-Based API Governance

I've been working on several Laravel-based APIs, and I'm beginning to gather a set of tools that I think is helpful for ensuring the APIs do not drift from their specified responses/behavior/structure/etc (as specified by an OAS3 spec).

Here are some of the tools I'm using:

Stoplight Studio (to create the spec)
Spectral (to lint the spec)
hotmeteor/spectator (to run "spec tests")

I have two questions:

Are other folks using governance tools for Laravel-based API's?
Can anyone recommend a tool for ensuring/monitoring that all API routes have tests?
