PLX Conversion Testing

Speller conversion test bench


  • augmented makefile to produce small test speller transducer, based on list of test words

Next steps:

  • check the size of the PLX output - if reasonable, store it in svn as reference
  • add spell checking of the test words as well, store the speller output in svn
  • edit manually the speller output to reflect what we want
  • edit manually the PLX codes until we get what we want from the speller
  • change the regular PLX conversion to reflect the manually tuned test PLX codes


This will still be one large test file. What we really want is a number of very small and focused tests.

Possible solution

  • define the test cases in terms of the words (ie classes) involved
  • split the PLX data on the test words, so that only data relating to the words for each test case is included.

The test cases should be stored like this:

$GTHOME/gt/$GTLANG/polderland/testing/caseN/words.txt        # in svn
                                            expected.plx     # in svn
                                            expected.speller # in svn

                                            speller.lex # <- binary speller file
                                            actual.plx       # NOT in svn
                                            actual.speller   # NOT in svn

                                     /caseAll/ concat all words, sort
                                            expected plx
                                            expected speller

Output from each test case:
