Public interface

expecteds/2

Returns the values stored in the expected term references that hold an expected term.

Compilation flags:
static
Template:
expecteds(References,Expecteds)
Mode and number of proofs:
expecteds(+list(expected),-list) - one

unexpecteds/2

Returns the values stored in the expected term references that hold an expected term.

Compilation flags:
static
Template:
unexpecteds(References,Unexpecteds)
Mode and number of proofs:
unexpecteds(+list(expected),-list) - one

partition/3

Retrieves and partitions the values stored in the expected term references.

Compilation flags:
static
Template:
partition(References,Expecteds,Unexpecteds)

Remarks

  • Type either(ExpectedType, UnexpectedType): Allows type-checking expected references where the expected and unexpected terms must be of the given types.
  • QuickCheck support: Defines clauses for the type::arbitrary/1-2 predicates to allow generating random values for the either(ExpectedType, UnexpectedType) type.
