Methods
_indexOf
-
haystack -
needle
Simple indexOf() implementation for an array. Defers to native if available.
Parameters:
-
haystackArrayThe array to search.
-
needleVariantThe value to locate.
Returns:
_some
-
haystack -
matcher
Simple some() implementation for an array. Defers to native if available.
Returns:
contains
-
needle -
haystack -
message
Asserts that a value is present in an array. This uses the triple equals sign so no type coercion may occur.
containsItems
-
needles -
haystack -
message
Asserts that a set of values are present in an array. This uses the triple equals sign so no type coercion may occur. For this assertion to pass, all values must be found.
containsMatch
-
matcher -
haystack -
message
Asserts that a value matching some condition is present in an array. This uses a function to determine a match.
doesNotContain
-
needle -
haystack -
message
Asserts that a value is not present in an array. This uses the triple equals Asserts that a value is not present in an array. This uses the triple equals sign so no type coercion may occur.
doesNotContainItems
-
needles -
haystack -
message
Asserts that a set of values are not present in an array. This uses the triple equals sign so no type coercion may occur. For this assertion to pass, all values must not be found.
doesNotContainMatch
-
matcher -
haystack -
message
Asserts that no values matching a condition are present in an array. This uses a function to determine a match.
indexOf
-
needle -
haystack -
index -
message
Asserts that the given value is contained in an array at the specified index. This uses the triple equals sign so no type coercion will occur.
isEmpty
-
actual -
message
Asserts that an array is empty.
isNotEmpty
-
actual -
message
Asserts that an array is not empty.
itemsAreEqual
-
expected -
actual -
message
Asserts that the values in an array are equal, and in the same position, as values in another array. This uses the double equals sign so type coercion may occur. Note that the array objects themselves need not be the same for this test to pass.
itemsAreEquivalent
-
expected -
actual -
comparator -
message
Asserts that the values in an array are equivalent, and in the same position, as values in another array. This uses a function to determine if the values are equivalent. Note that the array objects themselves need not be the same for this test to pass.
Parameters:
Returns:
itemsAreSame
-
expected -
actual -
message
Asserts that the values in an array are the same, and in the same position, as values in another array. This uses the triple equals sign so no type coercion will occur. Note that the array objects themselves need not be the same for this test to pass.
lastIndexOf
-
needle -
haystack -
index -
message
Asserts that the given value is contained in an array at the specified index, starting from the back of the array. This uses the triple equals sign so no type coercion will occur.
