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 an equal_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))

hamcrest.core.core.isnot.not_(match)¶

Alias of is_not for better readability of negations.

Examples:

assert_that(alist, not_(has_item(item)))
