proposal: testing: Support external packages to call testing.MainStart #51912
Description
Systems simulating go test have two methods to invoke tests:
testing.Mainhttps://pkg.go.dev/testing#Maintesting.MainStarthttps://pkg.go.dev/testing#MainStart
From the doc comments for Main, MainStart is preferred:
Systems simulating "go test" should be updated to use MainStart.
Previously, before go1.18, the internal interface testDeps could be satisfied by an external package. Upgrading to go1.18 the new internal interface contains methods with references to a private struct corpusEntry for the added fuzzing support. MainStart isn't part of the go compatibility promise. I propose providing an implementation of testDeps like

that could be used by external packages to call
MainStart.

My mistake, struct isn't private but an alias:
go/src/internal/fuzz/fuzz.go

Would be nice to have a defined public testdeps implementation but not a blocker, happy to close.

Doesn't seem like there is anything we need to do here, so closing. Please comment if you disagree.
