Logical Matchers¶
Boolean logic using other matchers.
all_of¶
-
hamcrest.core.core.allof.
all_of
(matcher1[, matcher2[, ...]])¶ Matches if all of the given matchers evaluate to
True
.Parameters: matcher1,... – A comma-separated list of matchers. 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
(matcher1[, matcher2[, ...]])¶ Matches if any of the given matchers evaluate to
True
.Parameters: matcher1,... – A comma-separated list of matchers. 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])¶ Matches anything.
Parameters: description – Optional string used to describe this matcher. 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)¶ 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))
