@ -33,9 +33,10 @@ Catch2's provided generator functionality consists of three parts,
* `GENERATE` macro, that serves to integrate generator expression with
a test case,
* 2 fundamental generators
* 3 fundamental generators
* `ValueGenerator<T>` -- contains only single element
* `ValuesGenerator<T>` -- contains multiple elements
* `RangeGenerator<T>` -- generates all values between `start` and `end`
* 4 generic generators that modify other generators
* `FilterGenerator<T, Predicate>` -- filters out elements from a generator
for which the predicate returns "false"

* `value(T&&)` for `ValueGenerator<T>`
* `values(std::initializer_list<T>)` for `ValuesGenerator<T>`
* `range(start, end)` for `RangeGenerator<T>` with a step size of `1`
