jpylyzer - create unittest to check whether all significant properties are mapped right way

[jstavel]

• see appCtx-differ-cmdline.xml. It is main source.

  So there is bean metadataExtractors.
  See where it is used.

  There is jpylyzerMetadataExtractor in the file.
  It will be called in a unittest to get output.

• please see, what structure the output is.

  There is ArraySet extractorProperties, identificationProperties, validationProperties, characterizationProperties in a file metadataSignificantProperties.
  All of them will be checked in the unittest.

• Choose two images that jpylyzer can recognize. See property supportedFileExtensions in a file jpylyzerMetadataExtractor.

• call jpylyzer by hand and try to recognize what values of significant properties the extractor gives.

• save the values of significant properties for a given image into some structure. I think you can create spring application context for junit.

• write junit test for bean jpylyzerMetadataExtractor to check, whether outputs it gives for a given image are the same as values by hand.

  If you have problem with collecting values of significant properties for given image I help you.
