Re: [QF-Test] Resolver Hook with isInstance()


  • Subject: Re: [QF-Test] Resolver Hook with isInstance()

Hi Michael,

there is no default isInstance method in Java or Python that takes a
String as argument.

In Java there is

    class.isInstance(obj)

and in Python there's the builtin

    isinstance(obj, class)

Both methods require you to first import the class you want to test
against.

For convenience QF-Test provides a static method in the
ResolverRegistry that will perform isInstance against a class name:

from de.qfs.apps.qftest.extensions import ResolverRegistry
ResolverRegistry.isInstance(obj, "javax.swing.Button")

This method is ideal for Jython based scripts and NameResolvers.

Best regards,
    Greg
