This is what I had with Tapestry 3.0.3, and using a MockRequestCycle
turns out to be much easier in Tapestry 4.0. Here's what I used:
public class MockRequestCycle extends RequestCycle {
public IPage getPage(String name) {
// convert the first character to uppercase
char first = Character.toUpperCase(name.charAt(0));
name = first + name.substring(1);
// if it ends in an "s", replace "s" with "List"
if (name.endsWith("s")) {
name = name.substring(0, name.length() - 1) + "List";
}
name = MockRequestCycle.class.getPackage().getName() + "." + name;
try {
return (IPage) new Creator().newInstance(Class.forName(name));
} catch (Exception e) {
// Instantiate a BasePage and hope that works
try {
return (IPage) new Creator().newInstance(BasePage.class);
} catch (Exception e2) {
e.printStackTrace();
throw new RuntimeException("Unable to instantiate '" +
name + "'");
}
}
}
}
