Issue Description:

Steps to Reproduce

Run the following commands:

$ swift build --init
$ swift build
$ swift test

Expected

Either for a default test to run, or some message describing what's expected.

Actual

The following error message is printed:

Usage: xctest [-XCTest All | <TestCaseClassName/testMethodName>] <path of unit to be tested>

Failure: No test bundle found at path `/path/to/swift-testing/.build/debug/Package.xctest`

Displaying process arguments and environment for debugging purposes:
Arguments: (
    "/Applications/Xcode-beta.app/Contents/Developer/usr/bin/xctest",
    "/path/to/swift-testing/.build/debug/Package.xctest"
)
Environment: {
    HOME = "<HOME>";
    PATH = "<PATH>";
    "SPM_INSTALL_PATH" = "/path/to/swift-testing/.build";
    "__CF_USER_TEXT_ENCODING" = "0x1F5:0:0";
}

Notes

Inspection of .build/debug.yaml showed that the list of test targets was empty. The workaround was to nest tests inside of a folder Tests/ModuleName/, at which point running swift build discovers the test targets and swift test will succeed in building and running the tests.

I think it would be useful for swift test to support a top-level testing module. At the very least I think an error message should be shown here, instead of continuing until the xctest failure.

I did some investigation, and swift-build-tool exits with a successful status code even if no modules are defined for the specified target.

Hi @sharplet, I've raised a PR (#162) to fix this issue.
