Cell Handler Acceptance Test

The first thing we're going to do is use the cell handler inspector to retrieve the current list of cell handlers.

fit.CellHandlerInspector

Next, let's clear the list.

fit.CellHandlerLoader
clear

And look at it again

fit.CellHandlerInspector

Now, we'll put the defaults back

fit.CellHandlerLoader
load defaults

And, presto! They've reappeared!

fit.CellHandlerInspector

Let's load an optional module

fit.CellHandlerLoader
loadSubstringCellHandler

And it appears in the list

fit.CellHandlerInspector

Let's get rid of one

fit.CellHandlerLoader
removeNumericRangeCellHandler

And it's gone

fit.CellHandlerInspector

Now let's try loading something that doesn't exist.

fit.CellHandlerLoader
loadNotACellHandler

And it wasn't loaded

fit.CellHandlerInspector
