xcodebuild test vs xcodebuild build test

This is a sample project demonstrating an Xcode bug.

Given

1. An iOS application

• created from the "Single View Application" template

2. whose build takes > 120 seconds

• faked with a Run Script phase that sleeps for 125 seconds

Notes

• Xcode 7.1: there might have been changes / improvements, as running bash test-fails.sh did not fail if the iOS Simulator was running, only if you don't have the simulator open (which is usually the case on a CI server/service)
  • this practically means that if you run bash test-ok.sh first and then bash test-fails.sh it'll work with Xcode 7.1, but not if you close the iOS Simulator and you just run bash test-fails.sh
  • if the Simulator is not open running bash test-fails.sh won't even open it
• Xcode 7.0, Xcode 6.4: running bash test-fails.sh it failes in every case

orig.test-only-fails.sh / test-fail.sh

Note: test-fail.sh is a minimized version of the original orig.test-only-fails.sh script, fails just like the original, more verbose version.

This build script runs xcodebuild test. During the build process, xcodebuild logs:

xcodebuild[54591:624937]  iPhoneSimulator: Timed out waiting 120 seconds for simulator to boot, current state is 1.

Just after xcodebuild touches the xctest bundle, it reports

** TEST FAILED **

without even trying to launch the simulator.

orig.build-and-test-succeeds.sh / test-ok.sh

Note: test-ok.sh is a minimized version of the original orig.build-and-test-succeeds.sh script, succeeds just like the original, more verbose version.

This build script runs xcodebuild build test. It takes just as long as the previous script to execute, but the iPhoneSimulator does not time out waiting to boot. Instead, the tests launch and run successfully.
