Data generators for Clojure.

*rnd* clj

Random instance for use in generators. By consistently using this instance you can get a repeatable basis for tests.

anything clj

(anything)

Returns a scalar or collection based on rnd.

bigdec clj

(bigdec)

bigint clj

(bigint)

boolean clj

(boolean)

Returns a bool based on rnd.

boolean-array clj

(boolean-array f)

(boolean-array f sizer)

Create an array with elements from f and sized from sizer.

byte clj

(byte)

Returns a long based on rnd in the byte range.

byte-array clj

(byte-array f)

(byte-array f sizer)

Create an array with elements from f and sized from sizer.

char clj

(char)

Returns a character based on rnd in the range 0-65536.

char-array clj

(char-array f)

(char-array f sizer)

Create an array with elements from f and sized from sizer.

collection clj

(collection)

Returns a collection of scalar elements based on rnd.

collections clj

date clj

(date)

(date base)

Create a date with geometric mean around base which defaults to #inst "2007-10-16T00:00:00.000-00:00"

default-sizer clj

(default-sizer)

Default sizer used to run tests. If you want a specific distribution, create your own and pass it to a fn that wants a sizer.

double clj

(double)

Generate a double between 0 and 1 based on rnd.

double-array clj

(double-array f)

(double-array f sizer)

(float)

Generate a float between 0 and 1 based on rnd

float-array clj

(float-array f)

(float-array f sizer)

Create an array with elements from f and sized from sizer.

geometric clj

(geometric p)

Geometric distribution with mean 1/p.

hash-map clj

(hash-map fk fv)

(hash-map fk fv sizer)

Create a hash-map with keys from fk, vals from fv, and sized from sizer.

int clj

(int)

Returns a int based on rnd in the int range.

int-array clj

(int-array f)

(int-array f sizer)

Create an array with elements from f and sized from sizer.

keyword clj

(keyword)

(keyword sizer)

Create a non-namespaced keyword sized from sizer.

list clj

(list f)

(list f sizer)

Create a list with elements from f and sized from sizer.

long clj

Returns a long based on rnd. Same as uniform.

long-array clj

(long-array f)

(long-array f sizer)

Create an array with elements from f and sized from sizer.

one-of clj

(one-of & specs)

Generates one of the specs passed in, with equal probability.

primitive-array clj macro

(primitive-array type)

primitive-arrays clj macro

(primitive-arrays types)

printable-ascii-char clj

(printable-ascii-char)

Returns a char based on rnd in the printable ascii range.

rand-nth clj

(rand-nth coll)

Replacement of core/rand-nth that allows control of the randomization basis (through binding rnd).

ratio clj

(ratio)

(ratio num-gen denom-gen)

Generate a ratio, with numerator and denominator uniform longs or as specified

reps clj

(reps sizer f)

Returns sizer repetitions of f (or (f) if f is a fn).

reservoir-sample clj

(reservoir-sample ct coll)

Reservoir sample ct items from coll, using rnd.

scalar clj

(scalar)

Returns a scalar based on rnd.

scalars clj

set clj

(set f)

(set f sizer)

Create a set with elements from f and sized from sizer.

short clj

(short)

Returns a short based on rnd in the short range.

short-array clj

(short-array f)

(short-array f sizer)

Create an array with elements from f and sized from sizer.

shuffle clj

(shuffle coll)

Shuffle coll based on rnd

string clj

(string)

(string f)

(string f sizer)

Create a string with chars from f and sized from sizer.

symbol clj

(symbol)

(symbol sizer)

Create a non-namespaced symbol sized from sizer.

tuple clj

(tuple & generators)

Generate a tuple with one element from each generator.

uniform clj

(uniform)

(uniform lo hi)

Uniform distribution from lo (inclusive) to hi (exclusive). Defaults to range of Java long.

uuid clj

(uuid)

Create a UUID based on uniform distribution of low and high parts.

vec clj

(vec f)

(vec f sizer)

Create a vec with elements from f and sized from sizer.

weighted clj

(weighted m)

Given a map of generators and weights, return a value from one of the generators, selecting generator based on weights.
