* 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.
