Re: Unit tests

[Howard Lewis Ship <hl...@gmail.com>]

You need to create a control for the mock, and inform the control what
to return from the mock.

I.e.

Object foobar = new FooBar();

MockControl cyclec = newControl(IRequestCycle.class);
IRequestCycle cycle = (IRequestCycle)cyclec.getMock();

cycle.getAttribute("foo.bar");
cyclec.setReturnValue(foobar);

...

// Setup all controls created with newControl() or newMock() to replay
// their scripts.

replayControls();

// Run tests that use the mock cycle trained above


// Ensure that all scripts for all controls completed.
verifyControls();
