Between
func Between(from interface{}, to interface{}, bounds ...BoundsKind) TestDeep
Between operator checks that data is between from and
to. from and to can be any numeric, string or time.Time (or
assignable) value. from and to must be the same kind as the
compared value if numeric, and the same type if string or time.Time (or
assignable). bounds allows to specify whether bounds are included
or not:
If bounds is missing, it defaults to BoundsInIn.
tc.Cmp(t, 17, td.Between(17, 20)) // succeeds, BoundsInIn by default
tc.Cmp(t, 17, td.Between(10, 17, BoundsInOut)) // fails
tc.Cmp(t, 17, td.Between(10, 17, BoundsOutIn)) // succeeds
tc.Cmp(t, 17, td.Between(17, 20, BoundsOutOut)) // fails
TypeBehind method returns the reflect.Type of from (same as the to one.)

Examples
Int example
t := &testing.T{}
got := 156
ok := td.Cmp(t, got, td.Between(154, 156),
"checks %v is in [154 .. 156]", got)
fmt.Println(ok)
// BoundsInIn is implicit
ok = td.Cmp(t, got, td.Between(154, 156, td.BoundsInIn),
"checks %v is in [154 .. 156]", got)
fmt.Println(ok)
ok = td.Cmp(t, got, td.Between(154, 156, td.BoundsInOut),

fmt.Println(ok)
ok = td.Cmp(t, got, td.Between(154, 156, td.BoundsOutIn),

fmt.Println(ok)
ok = td.Cmp(t, got, td.Between(154, 156, td.BoundsOutOut),
"checks %v is in ]154 .. 156[", got)

CmpBetween shortcut
func CmpBetween(t TestingT, got interface{}, from interface{}, to interface{}, bounds BoundsKind, args ...interface{}) bool
CmpBetween is a shortcut for:
td.Cmp(t, got, td.Between(from, to, bounds), args...)
See above for details.
Between() optional parameter bounds is here mandatory.
td.BoundsInIn value should be passed to mimic its absence in
original Between() call.
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.
