Unit Testing broken in iOS 4.1 SDK?

Question

After upgrading to the 4.1 iOS SDK my unit test bundles always return with the following two errors and one warning:

An internal error occurred when handling command output: -[XCBuildLogCommandInvocationSection setTestsPassedString:]: unrecognized selector sent to instance
An internal error occurred when handling command output: -[XCBuildLogCommandInvocationSectionRecorder endmarker:]: unrecognized selector sent to instance
Run unit tests for architecture 'i386' (GC OFF) did not finish

I get these errors despite it reporting that all X out of X tests passed. I read about a similar bug in an older version of XCode that also occurred immediately after it was released (something about a bug in a regular expression for time) that could be mitigated by setting your time zone to Pacific Time, but I can't say for sure it's a regression to there specifically.

Is anyone else having this problem?

Answer 1

There is a fix available on the apple dev forums,

https://devforums.apple.com/thread/68687

it's a date parsing problem. The fix is quick, it requires including one .m added to your test bundle. The fix is available above or from:

Answer 2

It does seem to be a regression with some part of the reporting code not respecting timezone issues. The output is tagged as ending before it began, so gets very confused and chokes.

One work-around, that I found somewhere on Google, is to change the Run Script stage of the target.

Change

"${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" 

to

"${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" 1> /tmp/RunUnitTests.out 

It’s working round the issue, rather than solving it, but does work.

Answer 3

This is a confirmed bug in Xcode 3.2.4/4.1 SDK. It has been reported to Apple.

Upgrading to Xcode 3.2.5/4.2 beta SDK solves the problem. I don't know if access to beta SDK:s is open, or if you need to be a registered developer, though.
