如何使用“内部”导入运行 go 核心库测试？

Question

I am trying to run the tests in crypto/tls . The problem is that every time I try to run tests I get :

common.go:20:2: use of internal package internal/cpu not allowed

This makes sense as tls is a package and does not have a local internal directory like a normal package.

So my question is how are these test run to get around this restriction?

Ok so here is the Quick and dirty method to run custom tests in the standard/core library:

1. Compile the core library and compiler:

 GOOS=linux GOARCH=amd64 ./all.bash

2. Set the GOROOT to the repo and run the test using package names:

$GOROOT=$PWD GOBIN=$PWD/bin GOMODCACHE=$PWD/pkg/mod GOPATH=/tmp/gotest ./bin/go test crypto/tls
