You wouldn't want to vend the CLI tool when you act as a dependency to other packages, or include the JSON mapper in your dependencies. Test dependency doesn't sound right in that context.</div><div><br></div><div>After the product <a href="https://github.com/apple/swift-evolution/blob/master/proposals/0146-package-manager-product-definitions.md" target="_blank">proposal</a> is implemented, you will be able to control what you vend to your clients, and we thought about adding ability to define dependencies in-line with target dependencies but left it out of the proposal to keep it simpler. Maybe this proposal can add that instead of a separate `testDependencies` property.
