/*
|
|
Unlike most tests, this is actually not meant as much for unit-testing, but more like performance-testing.
|
|
Compile this project in Release mode, then run it in folder that has NetherFort.cubeset prefabs, too, using
|
|
a higher number of repetitions (each repetition takes time on the order of a second); investigate the
|
|
runtime performance with a profiler.
|
|
|
|
The syntax to execute this test:
|
|
PieceGeneratorBFSTreeTest [<numRepetitions>]
|
|
numRepetitions is the number of NetherFort structures to be generated (default = 1)
