JUnit is a regression testing framework. It is used by the developer who implements unit tests in Java |
There are several approaches to unit testing SAF-based applications. Two popular techniques are direct Action invocation and testing interceptors and result-types independantly.
Direct Action Invocation
The simplest approach is to instantiate your Actions, call the appropriate setters, then invoke execute
. Calling the Action directly allows you to bypass all the complicated container setup.

Testing Interceptors and/or Result Types
Check out the test suites in XWork and SAF. These suites are comprehensive and provide a good starting point. Here's an example.

Map params = new HashMap();
params.put("@java.lang.System@exit(1).dummy", "dumb value");

extraContext.put(ActionContext.PARAMETERS, params);
try {
ActionProxy proxy = ActionProxyFactory.getFactory().
createActionProxy("", MockConfigurationProvider.MODEL_DRIVEN_PARAM_TEST, extraContext);
assertEquals(Action.SUCCESS, proxy.execute());
ModelDrivenAction action = (ModelDrivenAction) proxy.getAction();
TestBean model = (TestBean) action.getModel();
String property = System.getProperty("action.security.test");
assertNull(property);
} catch (Exception e) {
e.printStackTrace();
fail();
}
