| * CollatorTest is a base class for tests that can be run conveniently from |
| * the command line as well as under the Java test harness. |
| * <p> |
| * Sub-classes implement a set of methods named Test<something>. Each |
| * of these methods performs some test. Test methods should indicate |
| * errors by calling either err or errln. This will increment the |
| * errorCount field and may optionally print a message to the log. |
| * Debugging information may also be added to the log via the log |
| * and logln methods. These methods will add their arguments to the |
| * log only if the test is being run in verbose mode. |
