Overview

A fake engine that simply makes up it’s results, used in testing.

Used in BentoSearch’s own automated tests, but exposed publically because can be useful to use in your tests for software that uses BentoSearch too.

The nature of the fake results can be controlled by config variables:

:num_results

how many items to include in returned results (default specified per_page, or 10)

:total_items

total_items to report

:sort_definitions

hash for #sort_definitions

:link

link to give to each item in results

:error

set to an error value hash and results returned will all be failed? with that error hash.

:raise_exception_class

string name of exception class that the engine will raise and not catch,

to be caught by BentoSearch::SearchEngine wrapper possibly.
:timing

in seconds, fill out the results as if they took this long.
