Russ Cox: Go Testing by Example
Agreed with most of this but I’m skeptical of the rsc.io/script dsl approach. I’ll try it, though, because Russ is often right.
shameless advert: do you wish testify was implemented with generics and go-cmp, and had a more understandable surface area? Check out my small zero-dep library, Testy https://github.com/peterldowns/testy
shameless advert: do you want to write tests against your postgres database, but each new test adds seconds to your test suite? Check out pgtestdb, the marginal cost of each test is measured in tens of milliseconds, and each test gets a unique and isolated postgres instance — with all your migrations applied. https://github.com/peterldowns/pgtestdb

Show HN: SQL Dry Runs with SQL Simulator
Hi Weston, congratulations on launching. You've done a great job of explaining what the project is and how it works. I'm not in the ecosystem you've built this for so I can't comment too much on the project itself, but nice work communicating it.
If anyone is interested in testing code/sql against postgres, I recently released https://github.com/peterldowns/pgtestdb. It uses template databases and advisory locks to give each test its own unique database with a near-zero marginal cost for each additional test. Combined with a ram/tmpfs-backed postgres server that is tuned for performance, it goes extremely fast.
Currently just for golang but I'm planning on releasing equivalent-capability libraries for Python and Typescript over the next month. If anyone has any thoughts/comments/feedback/suggestions I'd be extremely thankful.

Show HN: SQL Dry Runs with SQL Simulator
I had this exact use cases a few months back: a big SQLite DB I didn't want to duplicate (and use twice the storage) before testing a change, on a filesystem without copy-on-write.
I wrote a fuse tool to provide copy-on-write for the file instead: https://github.com/remram44/cowblock
What are some alternatives?
