> A few requests for clarification from the proposal authors:
> 1. The proposal talks in several places about “test modules” (for example, “test-module is created per subdirectory of Tests”). How do these test modules interact with Package.swift? Does each of them have a separate target? If so, how is the test module name specified in the Target(…) entry?

There is no support for referring to test targets in the Package.swift as part of this proposal.

> 2. Perhaps answered by #1, how does Package.swift specify test-only dependencies (e.g. Quick) that are necessary to build tests, but should not be exported to downstream projects?

This is already a part of the package manager: https://github.com/apple/swift-package-manager/pull/74

> 3. You propose that “building a module also builds that module's corresponding tests.” Does this apply only to the top-level package, or to all of its dependencies? For example, if my FooApp depends on BarLib, and BarLib’s tests depend on HugeFancyTestFramework, do I have to download and compile HugeFancyTestFramework in order to build FooApp? (Hopefully not!)

HugeFancyTestFramework will not be downloaded or built.
