Assertion

Makes a new assertion that requires a given numeric value to match a value with some tolerance.

Makes a new Assertion from a pretty-printing and a function.

Makes a new Assertion from a pretty-printing and a function.

Makes a new Assertion[A] from a pretty-printing, a function (=> A) => Option[B], and an Assertion[B]. If the result of applying the function to a given value is Some[B], the Assertion[B] will be applied to the resulting value to determine if the assertion is satisfied. The result of the Assertion[B] and any assertions it is composed from will be recursively embedded in the assert result. If the result of the function is None the orElse parameter will be used to determine whether the assertion is satisfied.
