How can I run XCTest for a swift application from the command line?

Question

I want to test drive some Swift examples using XCTest from the command line if possible.

import XCTest

class LeapTest : XCTestCase {

    func testVanillaL         


        

Answer 1

I was able to get your XCTestCase compiling with the following command:

swiftc \
-F/Applications/Xcode6-Beta5.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Frameworks \
-Xlinker -rpath -Xlinker /Applications/Xcode6-Beta5.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Frameworks \
-lswiftCore LeapTest.swift \
-o LeapTests

Then you can execute the tests with xctest:

xcrun xctest LeapTests

And to break down those swiftc command line options:

1. -F... adds XCTest.framework to the framework search paths, enabling it to be imported from Swift
2. -Xlinker -rpath ... makes sure the XCTest shared library can be found at load time
3. Without explicitly specifying -lswiftCore, I found that xctest would crash when it tried to run the test suite

Hope that helps!

I think the issue is you have your test.swift file under the main project's target membership. Make sure your swift test files belong to the Test target only.
