"""Matches if an object has properties satisfying all of a dictionary
of string property names and corresponding value matchers.
:param matcher_dict: A dictionary mapping keys to associated value matchers,
or to expected values for
:py:func:`~hamcrest.core.core.isequal.equal_to` matching.
Note that the keys must be actual keys, not matchers. Any value argument
that is not a matcher is implicitly wrapped in an
:py:func:`~hamcrest.core.core.isequal.equal_to` matcher to check for
equality.
Examples::
has_properties({'foo':equal_to(1), 'bar':equal_to(2)})
has_properties({'foo':1, 'bar':2})
``has_properties`` also accepts a list of keyword arguments:
.. function:: has_properties(keyword1=value_matcher1[, keyword2=value_matcher2[, ...]])
:param keyword1: A keyword to look up.
:param valueMatcher1: The matcher to satisfy for the value, or an expected
value for :py:func:`~hamcrest.core.core.isequal.equal_to` matching.
Examples::
has_properties(foo=equal_to(1), bar=equal_to(2))
has_properties(foo=1, bar=2)
Finally, ``has_properties`` also accepts a list of alternating keys and their
value matchers:
.. function:: has_properties(key1, value_matcher1[, ...])
:param key1: A key (not a matcher) to look up.
:param valueMatcher1: The matcher to satisfy for the value, or an expected
value for :py:func:`~hamcrest.core.core.isequal.equal_to` matching.
Examples::
has_properties('foo', equal_to(1), 'bar', equal_to(2))
has_properties('foo', 1, 'bar', 2)
