qc.map βΈ¬ (a β b) β Gen a β Gen b
This allows you to define a generator in terms of another generator. This function is curried.
qc.of βΈ¬ a β Gen a
Creates a generator based on a constant value. This generator returns the constant value passed into it. In effect, it works like Lodash's _.constant
function.
expect(function(a) {
return a === 5;
}).forAll(qc.of(3));
expect (a) ->
a == 5
.forAll qc.of 3
expect(a => a === 5).forAll(qc.of(3));
qc.join βΈ¬ Gen (Gen a) β Gen a
Takes a generator generator and returns a generator. This way you can unwrap unnecessarily complex values.
