SeverityHandler corresponds to <severity> tag, nested in <classifiers> tag. As shown in the example of the previous section the body of <severity> tag contains the severity of the test. Now the user gives the global severity, which we will call the threshold severity in one of the following way: as an ant property called sqlunit.threshold.severity, as the value of the key sqlunit.threshold.severity from SQLUnit's SymbolTable or as a System property called sqlunit.threshold.severity. SeverityHandler will take the threshold severity, the current test's severity and will execute the test iff the current test's severity is equal ot greater than the threshold severity.
The following values are valid severity value: DEBUG, INFO, WARN, ERROR, FATAL and are compared in the following way: DEBUG < INFO < WARN < ERROR < FATAL. For example if the user invokes the test from the previous section with
the test will be executed because INFO <= WARN. But if it is invoked with
the test will not be executed as ERROR > WARN.
Since <severity> is an optional tag, the following edge cases are taken into account: if the threshold severity is not set all tests match regardless of their severities; if a test does not have assigned severity it matches, regardless of the threshold severity.
