func Bag(expectedItems ...interface{}) TestDeep
Bag
operator compares the contents of an array or a slice (or a
pointer on array/slice) without taking care of the order of items.
During a match, each expected item should match in the compared array/slice, and each array/slice item should be matched by an expected item to succeed.
Cmp(t, []int{1, 1, 2}, Bag(1, 1, 2)) // succeeds
Cmp(t, []int{1, 1, 2}, Bag(1, 2, 1)) // succeeds
Cmp(t, []int{1, 1, 2}, Bag(2, 1, 1)) // succeeds
Cmp(t, []int{1, 1, 2}, Bag(1, 2)) // fails, one 1 is missing
Cmp(t, []int{1, 1, 2}, Bag(1, 2, 1, 3)) // fails, 3 is missing

func CmpBag(t TestingT, got interface{}, expectedItems []interface{}, args ...interface{}) bool
CmpBag is a shortcut for:
Cmp(t, got, Bag(expectedItems...), args...)
See above for details.
Returns true if the test is OK, false if it fails.
args… are optional and allow to name the test. This name is
used in case of failure to qualify the test. If len(args) > 1
and
the first item of args is a string
and contains a ‘%’ rune
then
fmt.Fprintf
is used to compose the name, else args are passed to
fmt.Fprint
. Do not forget it is the name of the test, not the
reason of a potential failure.
