* Test the functions getMaximum/getGeratestMinimum logically correct.
* This method assumes day of week cycle is consistent.
* @param cal The calendar instance to be tested.
* @param leapMonth true if the calendar system has leap months
void doTheoreticalLimitsTest(Calendar& cal, UBool leapMonth);
* Test the functions getXxxMinimum() and getXxxMaximum() by marching a
* test calendar 'cal' through 'numberOfDays' sequential days starting
* with 'startDate'. For each date, read a field value along with its
* reported actual minimum and actual maximum. These values are
* checked against one another as well as against getMinimum(),
* getGreatestMinimum(), getLeastMaximum(), and getMaximum(). We
* expect to see:
* 1. minimum <= actualMinimum <= greatestMinimum <=
* leastMaximum <= actualMaximum <= maximum
* 2. actualMinimum <= value <= actualMaximum
* Note: In addition to outright failures, this test reports some
* results as warnings. These are not generally of concern, but they
* should be evaluated by a human. To see these, run this test in
* verbose mode.
* @param cal the calendar to be tested
* @param fieldsToTest an array of field values to be tested, e.g., new
* int[] { UCAL_MONTH, UCAL_DAY_OF_MONTH }. It only makes
* sense to test the day fields; the time fields are not tested by this
* method. If null, then test all standard fields.
* @param startDate the first date to test
* @param testDuration if positive, the number of days to be tested.
* If negative, the number of seconds to run the test.
