Allow a 'callback' argument to be passed to $() and a new $callback() method
Luis, we discussed this briefly @ SotR.
Currently one can specify a expression to use for a $results() value, and the value of that expression is then used as the results for the mocked method.
It would be occasionally handy for some stub code to be run to provide the results when a mocked method is called. This could be effected by being able to pass a callback to $results(), which is then called to provide the results when the mocked method itself is called.
Ideally a mocked method should always be able to be fairly dumb, but sometimes in an imperfect world where the mocked method has other dependencies which cannot be mocked out, an actual usable result is necessary. We've needed to do this about... hmmm... 0.5% of the times in out unit tests I think, so this is quite edge-case-y.
I get it now. thanks Adam
I have been thinking further about this and it causes an issue. What if you really wanted to return a closure or a UDF value?
