[swift-build-dev] How to run SPM Tests from generated Xcode proj?

[Jose Cheyo Jimenez]

Hello, 

I am having trouble figuring out how to run the xctests from the Swift Package Manager Package itself.

Some of the tests succeed but the majority fail. Thanks!

STEPS:

Cloned SPM from github
Downloaded latest Swift Tool chain
Generated Xcode project file (Xcode 8.2)
On each target I added a global flag:
SWIFT_EXEC=/Library/Developer/Toolchains/swift-DEVELOPMENT-SNAPSHOT-2016-12-13-a.xctoolchain/usr/bin/swift
Run Tests for SwiftPM. 

177 Tests fail. 

Sample error:

../swift-package-manager/Tests/FunctionalTests/ClangModuleTests.swift: test failure: 
-[ClangModulesTestCase testCUsingCDep()] failed: failed - `swift build -c Debug' failed:
