otest-shim

otest-shim tricks OCUnit into outputting test results in structured JSON rather than in plain text. It also captures any stdout / stderr output generated by individual tests.

Instead of writing plain text like this:

Test Suite

It makes otest output JSON events, one per line:

{"event":"begin-test-suite","suite":"\/Users\/fpotter\/Library\/Developer\/Xcode\/DerivedData\/TestProject-Library-OSX-cdgcsjlcfmpqvnbvrmphsrtbqvhp\/Build\/Products\/Debug\/TestProject-Library-OSXTests.octest(Tests)"}

Usage

Here's an example of how you would load the shim when running an OCUnit test bundle for OSX:

DYLD_INSERT_LIBRARIES=path/to/otest-shim-osx.dylib \
  OBJC_DISABLE_GC=YES \
  DYLD_LIBRARY_PATH=~/Library/Developer/Xcode/DerivedData/SomeProject-cdgcsjlcfmpqvnbvrmphsrtbqvhp/Build/Products/Debug/ \
  /Applications/Xcode.app//Contents/Developer/Tools/otest \
  ~/Library/Developer/Xcode/DerivedData/SomeProject-cdgcsjlcfmpqvnbvrmphsrtbqvhp/Build/Products/Debug/SomeProject-Tests.octest

Actual usage varies depending on whether you're targeting iOS or Mac, or Logic or Application tests.
