Number Matchers¶
Matchers that perform numeric comparisons.
close_to¶
-
class
hamcrest.library.number.iscloseto.IsCloseTo(value, delta)¶ Bases:
hamcrest.core.base_matcher.BaseMatcher-
describe_mismatch(item, mismatch_description)¶ Generates a description of why the matcher has not accepted the item.
The description will be part of a larger description of why a matching failed, so it should be concise.
This method assumes that
matches(item)isFalse, but will not check this.- Parameters
item – The item that the
Matcherhas rejected.mismatch_description – The description to be built or appended to.
-
describe_to(description)¶ Generates a description of the object.
The description may be part of a description of a larger object of which this is just a component, so it should be worded appropriately.
- Parameters
description – The description to be built or appended to.
-
-
hamcrest.library.number.iscloseto.close_to(value, delta)¶ Matches if object is a number close to a given value, within a given delta.
- Parameters
value – The value to compare against as the expected value.
delta – The maximum delta between the values for which the numbers are considered close.
This matcher compares the evaluated object against
valueto see if the difference is within a positivedelta.Example:
close_to(3.0, 0.25)
-
hamcrest.library.number.iscloseto.isnumeric(value)¶ Confirm that ‘value’ can be treated numerically; duck-test accordingly
greater_than, greater_than_or_equal_to, less_than, less_than_or_equal_to¶
-
class
hamcrest.library.number.ordering_comparison.OrderingComparison(value, comparison_function, comparison_description)¶ Bases:
hamcrest.core.base_matcher.BaseMatcher-
describe_to(description)¶ Generates a description of the object.
The description may be part of a description of a larger object of which this is just a component, so it should be worded appropriately.
- Parameters
description – The description to be built or appended to.
-
-
hamcrest.library.number.ordering_comparison.greater_than(value)¶ Matches if object is greater than a given value.
- Parameters
value – The value to compare against.
-
hamcrest.library.number.ordering_comparison.greater_than_or_equal_to(value)¶ Matches if object is greater than or equal to a given value.
- Parameters
value – The value to compare against.
-
hamcrest.library.number.ordering_comparison.less_than(value)¶ Matches if object is less than a given value.
- Parameters
value – The value to compare against.
-
hamcrest.library.number.ordering_comparison.less_than_or_equal_to(value)¶ Matches if object is less than or equal to a given value.
- Parameters
value – The value to compare against.
