Correct bad test cases and intermitent failure

The filelist test was non-deterministic and causing intermittent
failures due to ordering. This change will ensure that the file list
returns an ordered list of files in the String() method now.

Additionally there were a number of test cases that the sample code
was incorrect, or would not compile. These have also been corrected.
