Array
func Array(model interface{}, expectedEntries ArrayEntries) TestDeep
Array operator compares the contents of an array or a pointer on an
array against the non-zero values of model (if any) and the
values of expectedEntries.
model must be the same type as compared data.
expectedEntries can be nil, if no zero entries are expected and
no TestDeep operator are involved.
got := [3]int{12, 14, 17}
td.Cmp(t, got, td.Array([3]int{0, 14}, td.ArrayEntries{0: 12, 2: 17})) // succeeds
td.Cmp(t, got,
td.Array([3]int{0, 14}, td.ArrayEntries{0: td.Gt(10), 2: td.Gt(15)})) // succeeds
TypeBehind method returns the reflect.Type of model.

Examples
Array example
t := &testing.T{}
got := [3]int{42, 58, 26}
ok := td.Cmp(t, got,
td.Array([3]int{42}, td.ArrayEntries{1: 58, 2: td.Ignore()}),
"checks array %v", got)
fmt.Println(ok)
// Output:
// true
TypedArray example
t := &testing.T{}
type MyArray [3]int
got := MyArray{42, 58, 26}
ok := td.Cmp(t, got,
td.Array(MyArray{42}, td.ArrayEntries{1: 58, 2: td.Ignore()}),
"checks typed array %v", got)
fmt.Println(ok)
ok = td.Cmp(t, &got,
td.Array(&MyArray{42}, td.ArrayEntries{1: 58, 2: td.Ignore()}),
"checks pointer on typed array %v", got)
fmt.Println(ok)
ok = td.Cmp(t, &got,
td.Array(&MyArray{}, td.ArrayEntries{0: 42, 1: 58, 2: td.Ignore()}),
"checks pointer on typed array %v", got)
fmt.Println(ok)

td.Array((*MyArray)(nil), td.ArrayEntries{0: 42, 1: 58, 2: td.Ignore()}),
"checks pointer on typed array %v", got)
fmt.Println(ok)
// Output:
// true
// true
// true

CmpArray shortcut
func CmpArray(t TestingT, got interface{}, model interface{}, expectedEntries ArrayEntries, args ...interface{}) bool
CmpArray is a shortcut for:
td.Cmp(t, got, td.Array(model, expectedEntries), 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.
See also CmpArray godoc.
