■ selectIf expression in test description - This mechanism provides a flexible
way for developers to make individual tests selectable
(com.sun.tck.j2me.javatest.ExprFilter) by including a selectIf
expression in test description.
The test developer can include a selectIf expression in the test description file
for a test. Each selectIf field contains a Boolean expression that is evaluated by
the filter. The test is selected by the harness for a test run if the value is true. See
“selectIf Test Selection” on page 71.
■ Grant or deny mechanism - This mechanism enables users to select tests based on
the security requirements (com.sun.tck.midp.policy.PermissionFilter)
specified by the test developer.
Tests are selected if all the permissions listed by the developer in the grant or
deny test description field are granted or denied. See “Granting or Denying
Security Permissions” on page 64.
■ Custom test suite-specific filters - Developers can extend the test suite with
custom test suite-specific filters. The JavaTest Architect’s Guide describes creating
custom filters.
selectIf Test Selection
The following procedures describe how developers can use the selectIf
expression to enable filtering tests that are not applicable for an implementation.
▼ To Enable Test Selection with the selectIF Expression
The selectIf entry in the test description file contains a Boolean expression which
is evaluated by a test filter. If the Boolean expression evaluates to false, the test is not
run. If the expression evaluates to true, the test is run.
