Random number generator

BaseTestSpec::rnd​

BaseTestSpec exposes a random number generator object rnd that can be utilized to define test cases. The following methods are available on it:

nextInt(minNum, maxNum)​

int nextInt(int minNum, int maxNum);

Returns a uniformly distributed random integer (int) between minNum and maxNum, inclusive.

nextInt(maxNumEx)​

int nextInt(int maxNumEx);

Returns a uniformly distributed random integer (int) between 0 and maxNumEx - 1, inclusive.

nextLongLong(minNum, maxNum)​

long long nextLongLong(long long minNum, long long maxNum);

Returns a uniformly distributed random integer (long long) between minNum and maxNum, inclusive.

nextLongLong(maxNumEx)​

long long nextLongLong(long long maxNumEx);

Returns a uniformly distributed random integer (long long) between 0 and maxNumEx - 1, inclusive.

nextDouble(minNum, maxNum)​

double nextDouble(double minNum, double maxNum);

Returns a uniformly distributed random real number (double) between minNum and maxNum, inclusive.

nextDouble(maxNum)​

double nextDouble(double maxNum);

Returns a uniformly distributed random real number (double) between 0 and maxNum, inclusive.

shuffle(first, last)​

void shuffle(std::RandomAccessIterator first, std::RandomAccessIterator last);

Randomly shuffles the elements in [first, last). Use this instead of std::random_shuffle().
