While testing out the new
buildConfigurationproperty on the macro expansion context, I noticed that when my macro was expanding in unit tests the macro was not receiving the build configuration. The root cause was thatBasicMacroExpansionContextdid not implementvar buildConfigurationdirectly and was instead picking up the default implementation which always returnsnil. This change implements the property by returning the value from the shared state.I couldn't find existing tests that exercise the build configuration as part of an expansion context, but if there's a good place to add a unit test let me know and I can try to add that.
