[section Helpers]
This section presents macros used to help with defining custom constraints.
[section MOCK_UNARY_CONSTRAINT]
Synopsis :
MOCK_UNARY_CONSTRAINT( name, expression ) // defines a constraint 'name' based on the given 'expression'
The expression manipulates the received parameter 'actual' in order to implement the constraint.
Example :
MOCK_UNARY_CONSTRAINT( any, true ) // this is (almost) how mock::any is defined
MOCK_UNARY_CONSTRAINT( forty_two, actual == 42 ) // this defines a 'forty_two' constraint
[endsect]
[section MOCK_BINARY_CONSTRAINT]
Synopsis :
MOCK_BINARY_CONSTRAINT( name, expression ) // defines a constraint 'name' based on the given 'expression'
The expression manipulates the received parameter 'actual' as well as the passed argument 'expected' in order to implement the constraint.
[note The type of expected must be copy-constructible and assignable]
Example :
MOCK_BINARY_CONSTRAINT( equal, actual == expected ) // this is how mock::equal is defined
MOCK_BINARY_CONSTRAINT( near, std::abs( actual - expected ) < 0.01 ) // this defines a 'near' constraint which can be used as 'near( 42 )'
