randomIntBetween

public int randomIntBetween(int min,
                            int max)

A random integer from min to max (inclusive).

randomInt

public int randomInt(int max)

A random integer between 0 and max (inclusive).

randomBoolean

public boolean randomBoolean()

randomInt

public int randomInt()

randomAsciiOfLength

public String randomAsciiOfLength(int count)

Creates a random string whose length is the number of characters specified. Characters will be chosen from the set of alphabetic characters. Note that this is based on RandomStringUtils which does not support providing a source of randomness. So this method does not use the same seed as other methods in this class.

rarely

public boolean rarely()

Rarely returns true in about 10% of all calls.

getRandom

public Random getRandom()
