NAME

Assert::Refute::Contract - Contract definition class for Assert::Refute suite

DESCRIPTION

This class represents a contract and is thus immutable.

See Assert::Refute::Exec for its application to a specific case.

SYNOPSIS

    use Assert::Refute::Contract;

    my $contract = Assert::Refute::Contract->new(
        code => sub {
            my ($c, $life) = @_;
            $c->is( $life, 42 );
        },
        need_object => 1,
    );

    # much later
    my $result = $contract->apply( 137 );
    $result->get_count;  # 1
    $result->is_passing; # 0
    $result->get_tap;    # Test::More-like summary

DESCRIPTION

This is a contract specification class. See Assert::Refute::Exec for execution log. See "contract" in Assert::Refute for convenient interface.

OBJECT-ORIENTED INTERFACE

new

    Assert::Refute::Contract->new( %options );

%options may include:

  • code (required) - contract to be executed

  • need_object - if given, a contract execution object will be prepended to code's argument list, as if it was a method.

    This allows to run a contract without exporting anything to the calling package.

    The name is not final, better suggestions wanted.

  • args = n or args = [min, max] - set limitation on the number of accepted parameters. Negative maximum value means unlimited.

adjust( %overrides )

Return a copy of this object with some overridden fields.

The name is not perfect, better ideas wanted.

%overrides may include:

  • backend - the class to perform tests.

apply( @parameters )

Spawn a new execution log object and run contract against it.

Returns a locked Assert::Refute::Exec instance.
