33 * the command line as well as under the Java test harness. |
|
34 * <p> |
|
35 * Sub-classes implement a set of methods named Test<something>. Each |
|
36 * of these methods performs some test. Test methods should indicate |
|
37 * errors by calling either err or errln. This will increment the |
|
38 * errorCount field and may optionally print a message to the log. |
|
39 * Debugging information may also be added to the log via the log |
|
40 * and logln methods. These methods will add their arguments to the |
|
41 * log only if the test is being run in verbose mode. |
