Method Detail

randomSeed64

public static long randomSeed64()

Provides a (possibly) random initial seed for randomized stuff, 64 bit version. If tests.seed property is available and accessible, the returned value will be derived from the value of that property and will be constant to ensure reproducibility in presence of the randomized testing package, which sets this property. Full random values are returned if either tests.seed is not available, or is set to "" (empty String).

randomSeed32

public static int randomSeed32()

Same as randomSeed64(), but returns 32 bit

forceReloadTestProperty

public static void forceReloadTestProperty()

Call this in order to make randomSeed64() or randomSeed32() re-read the tests.seed property which control their random number generation.
