5.3-DEVELOPMENT-SNAPSHOT-2020-05-19-a

Apple Swift version 5.3-dev (LLVM d2c5a6fb91, Swift 4eac5a1f0f) Target: x86_64-apple-darwin19.5.0

Swift Package Manager - Swift 5.3.0

Issue Description:

When using resources in combination with testTargets, the resources cannot be found. This happens regardless if the resource is in a library which is being tested or in the test target itself. The resource is being loaded via the new Bundle.module.

For minimal reproducible code including full debug output see https://github.com/Nef10/SPMResourcesInTest (or attachment)

The code tries to load the bundle from

/Applications/Xcode.app/Contents/Developer/usr/bin/BUNDLENAME.bundle

This is where the xctest executable is located. Te loading happens in the resource_bundle_accessor.swift which the SPM writes. In there it uses Bundle.main.bundlePath to get the bundle path. According to https://forums.swift.org/t/bundle-main-path-pointing-to-odd-path/13814 it is correct that Bundle.main in case of test execution points to the directory of the xctest executable.

Therefor I think the resource_bundle_accessor.swift needs adjustment to find the correct bundle path in case of test targets. The resources are correctly copied to a bundle in the .build directory
