Run "ant checkTest" in exhaustive mode
When running a single test on the command line, it is usually desired for it to be run in exhaustive mode, since you don't have to wait for the full test suite, and you can always selectively run a smaller test. We should make it the behavior that "ant checkTest" runs tests in exhaustive mode.
Sorry - I confirmed it does not work. I looked at build.xml carefully and found checkTest target does not have a mechanism to pass generic arguments.
If I run:
ant checkTest -Dtestclass='com.ibm.icu.dev.test.number.ExhaustiveNumberTest' -DICU.exhaustive=10
[junit] Tests run: 4, Failures: 0, Errors: 0, Skipped: 4, Time elapsed: 0.082 sec
So that extra ant argument doesn’t appear to be sufficient.
I think this one - http://site.icu-project.org/setup/java/ant#TOC-Test-arguments-and-running-just-one-test-or-the-tests-of-just-one-test-class with extra param -DICU.exhaustive=10 can be used for running a single test with exhaustive mode.
