Test.swift - An XCTestCase fixture that illustrates the failure output of every XCTAssert* function available in Swift. It builds and runs as-is on Darwin with Xcode's XCTest, and builds with swift-corelibs-xctest by including the currently-commented elements.
XCTest-Darwin-Output-Complete.txt - The output produced by Darwin XCTest when executing the fixture
XCTest-Darwin-Output-Filtered.txt - The XCTest output filtered to only include the lines containing an assertion failure message.

This is intended to be used when developing swift-corelibs-xctest to help verify that it appropriately mimics Darwin's XCTest output.
