I was recently debugging an issue in some integration-style Go tests which made me realize that I didn't have a very deep understanding of how parallelism works when using go test. I knew that there were ways that Go could parallelize tests, and I thought it had something to do with using t.Parallel() inline in each of my test functions.

Because I feel the concurrency behavior of go test is non-obvious, and for posterity so I don't forget in the future, I wanted to write something up here to document my understanding of how go test parallelization works as of Go 1.19.
