Running Tests

You will always need to run tests when you do a check-in.
    1. Preconditions
      • If you change the DTD, be sure to read and follow Updating DTDs first.
      • If you added a new feature or fixed a significant bug, add a unit test for it. 
        • See unittest/NumberingSystemsTest as an example. 
        • Remember to add to unittest/TestAll
    2. Run TestAll -e
      • These are the unit tests in exhaustive mode
      • If you are doing something you know to be simple, you could do the shorter run of just TestAll
    3. Run ConsoleCheckCLDR -e -z final_testing -S common,seed
      • This runs the same set of test that the Survey Tool does.
      • If you know what you are doing, you can run a set of filtered tests.
    4. Other tests
      1. The unit tests are not complete, so you get a better workout if you are doing anything fancy by running:
      2. NewLdml2IcuConverter
      3. Generating Charts
        1. If you have interesting new data, write a chart for it. See subclasses of Chart.java for examples.

    Running tests on the command line

    $ export CLDR_DIR=/path/to/svn/root/for/cldr
    $ cd $CLDR_DIR/tools/java && ant all
    $ cd $CLDR_DIR/tools/cldr-unittest && ant unittestExhaustive datacheck

    [TODO: add more commands here; can't we automate all this into a single build rule for ant?] TODO: TODOL ticket:8864 

    Debugging

    [TODO: add more tips here]

    Regexes

    We use a lot of regexes!
    1. There is org.unicode.cldr.util.RegexUtilities.showMismatch (and related methods) that are really useful in debugging cases where regexes fail. You hand it a pattern or matcher and a string, and it shows how far the regex got before it failed.
    2. To debug RegexLookup, there is a special call you can make where you pass in a set. On return, that set is filled with a set of strings showing how far each of the regex patterns progressed. You can thus see why a string didn't match as expected.
