test_case_combinator library

A small library with no dependencies that simplifies writing tests where verifying all possible combinations of the input parameters is required.

An example would be a function like this:

bool isAll(bool a1, bool a2, bool a3, bool a4, bool a6) {
  return a1 && a2 && a3 && a4 && a5 && a6;
}

To fully test the function above you would need 32 test cases, where only one is expected to produce the true result. That is a lot of test cases to write, and it is easy to make a typo on the way.

This library allows easily solving a task like that by allowing all test cases to be generated automatically from combinations of the input parameters.

Classes

TestCaseCombinator<T>

Builder for test cases based on all possible combinations of the input arguments.

Typedefs

TestCaseCombinatorArgument<T> = (Iterable, T Function(T, dynamic))

An argument for TestCaseCombinator, that provides the values the argument could take, and a function which applies a particular value to the resulting test case T.
