+Following is a testing script for the retrieval of metadata methods in imcflibs.imagej.bioformats.
+
+Copy the following code to a Fiji that has the release `python-imcflibs-1.5.0.jar` in the /jars directory.
+
+Add the source folder and the names of the files under the corresponding lines, and run the script. If the metadata is printed in Fiji output, the methods are working as intended
+
