ephphatha	ac8d40458c	Add tests for corner cases of the distribution functions Hoping to add a few tests for normal operation as a sanity check. The eventual goal is to be able to split the distribution functions from the engine so they can be tested and implemented independently.	5 years ago
ephphatha	a88f991746	Declare RandomTest test suite in the devilution namespace This is recommended for GTest and is a requirement to use FRIEND_TEST (see http://google.github.io/googletest/reference/testing.html#FRIEND_TEST). If the random number generator code becomes a class with private attributes this allows us to switch to test fixtures more easily.	5 years ago
ephphatha	5b0accb13c	Make it clearer when seeds are being converted from unsigned to signed	5 years ago
ephphatha	8d5b5e833b	Add tests for LCG random engine This documents the chosen LCG parameters and the default mapping function used in random number generation. GetLCGEngineState() is a helper needed for testing because AdvanceRndSeed combines a distribution with a call to progress the engine. I'll split those eventually but this at least shows the current behaviour and should flag any bugs introduced by future changes.	5 years ago
