SuperBagOf

func SuperBagOf(expectedItems ...interface{}) TestDeep

SuperBagOf 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. But some items in the compared array/slice may not be expected.

td.Cmp(t, []int{1, 1, 2}, td.SuperBagOf(1))       // succeeds
td.Cmp(t, []int{1, 1, 2}, td.SuperBagOf(1, 1, 1)) // fails, one 1 is missing

// works with slices/arrays of any type
td.Cmp(t, personSlice, td.SuperBagOf(
  Person{Name: "Bob", Age: 32},
  Person{Name: "Alice", Age: 26},
))

To flatten a non-[]interface{} slice/array, use Flatten function and so avoid boring and inefficient copies:

expected := []int{1, 2, 1}
td.Cmp(t, []int{1}, td.SuperBagOf(td.Flatten(expected))) // succeeds
// = td.Cmp(t, []int{1}, td.SuperBagOf(1, 2, 1))

exp1 := []int{5, 1, 1}
exp2 := []int{8, 42}
td.Cmp(t, []int{1, 5, 1, 8, 42, 3, 3, 6},
  td.SuperBagOf(td.Flatten(exp1), 3, td.Flatten(exp2))) // succeeds
// = td.Cmp(t, []int{1, 5, 1, 8, 42, 3, 3, 6}, td.SuperBagOf(5, 1, 1, 3, 8, 42))

Example

Base example

CmpSuperBagOf shortcut

func CmpSuperBagOf(t TestingT, got interface{}, expectedItems []interface{}, args ...interface{}) bool

CmpSuperBagOf is a shortcut for:

td.Cmp(t, got, td.SuperBagOf(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.
