Logical Matchers¶
Boolean logic using other matchers.
See also, Logical matcher internals
all_of¶
- hamcrest.core.core.allof.all_of(*items)¶
Matches if all of the given matchers evaluate to
True
.- Parameters:
- Return type:
Matcher[T]
The matchers are evaluated from left to right using short-circuit evaluation, so evaluation stops as soon as a matcher returns
False
.Any argument that is not a matcher is implicitly wrapped in an
equal_to
matcher to check for equality.
any_of¶
- hamcrest.core.core.anyof.any_of(*items)¶
Matches if any of the given matchers evaluate to
True
.- Parameters:
- Return type:
Matcher[T]
The matchers are evaluated from left to right using short-circuit evaluation, so evaluation stops as soon as a matcher returns
True
.Any argument that is not a matcher is implicitly wrapped in an
equal_to
matcher to check for equality.
anything¶
- hamcrest.core.core.isanything.anything(description=None)¶
Matches anything.
- Parameters:
description (Optional[str]) – Optional string used to describe this matcher.
- Return type:
This matcher always evaluates to
True
. Specify this in composite matchers when the value of a particular element is unimportant.
is_not¶
- hamcrest.core.core.isnot.is_not(match: Type) Matcher[object] ¶
- hamcrest.core.core.isnot.is_not(match: Union[Matcher[T], T]) Matcher[T]
Inverts the given matcher to its logical negation.
- Parameters:
match – The matcher to negate.
This matcher compares the evaluated object to the negation of the given matcher. If the
match
argument is not a matcher, it is implicitly wrapped in anequal_to
matcher to check for equality, and thus matches for inequality.Examples:
assert_that(cheese, is_not(equal_to(smelly))) assert_that(cheese, is_not(smelly))
