ExternalData: Add tests covering interfaces and errors Add a Module.ExternalData test to verify data retrieval and test argument DATA{} references. Add a RunCMake.ExternalData test to verify error handling and automatic transformation of a raw data to a content link and staged object. 2013-01-25 21:39:57 +00:00			`include(ExternalData)`
ExternalData: Warn on missing file instead of failing When the primary source tree path named by a DATA{} reference does not exist, produce an AUTHOR_WARNING instead of a FATAL_ERROR. This is useful when writing a new DATA{} reference to a test reference output that has not been created yet. This way the developer can run the test, manually verify the output, and then copy it into place to provide the reference and eliminate the warning. If the named source tree path is expected to be a file but exists as a directory, we still need to produce a FATAL_ERROR. 2014-04-17 13:31:41 +00:00
