Run all tests for a Workspace with One command (Proposal)

[zacharyjones123]

Problem

I currently have a project with multiple modules. I'm using the new workspace feature in 1.18 and it works fantastically for getting dependencies and organizing my workflow better. One issue I'm having is actually testing all of the different modules at the same time.

go.work

go 1.18

use (
	./example
	./example/template
	./hello
	./hello/something
)

Given my current go.work above, I can test manually by running each of the use directories separately

How I run tests manually

go test ./example
go test ./example/template
go test ./hello
go test ./hello/something

Proposed Solution

Have a single command that will run all of the tests for your given workspace.

There is currently a -workfile flag but I can't for the life of me find documentation or how to get that working.

My attempt at getting -workfile flag working

-  go-go-go git:(main) ✗ go test -workfile=go.work
no Go files in /Users/zachajon/Projects/delete_later/go-go-go

I'm completely open to all feedback and help that can be given! This is my first time posting an issue to an open source project like this and I'm nervous and super excited!!!
