Any
func Any(expectedValues ...any) TestDeep
Any operator compares data against several expected values. During
a match, at least one of them has to match to succeed. Consider it
as a “OR” logical operator.
td.Cmp(t, "foo", td.Any("bar", "foo", "zip")) // succeeds
td.Cmp(t, "foo", td.Any(
td.Len(4),
td.HasPrefix("f"),
td.HasSuffix("z"),
)) // succeeds coz "f" prefix
Note Flatten function can be used to group or reuse some values or
operators and so avoid boring and inefficient copies:
stringOps := td.Flatten([]td.TestDeep{td.HasPrefix("f"), td.HasSuffix("z")})
td.Cmp(t, "foobar", td.All(
td.Len(4),
stringOps,
)) // succeeds coz "f" prefix
TypeBehind method can return a non-nil reflect.Type if all items
known non-interface types are equal, or if only interface types
are found (mostly issued from Isa()) and they are equal.
See also All and None.

Example
Base example
t := &testing.T{}
got := "foo/bar"
// Checks got string against:
// "zip" regexp *OR* "bar" suffix
ok := td.Cmp(t, got, td.Any(td.Re("zip"), td.HasSuffix("bar")),
"checks value %s", got)
fmt.Println(ok)
// Checks got string against:
// "zip" regexp *OR* "foo" suffix
ok = td.Cmp(t, got, td.Any(td.Re("zip"), td.HasSuffix("foo")),
"checks value %s", got)
fmt.Println(ok)
// When some operators or values have to be reused and mixed between
// several calls, Flatten can be used to avoid boring and
// inefficient []any copies:
regOps := td.Flatten([]td.TestDeep{td.Re("a/c"), td.Re(`^xx`), td.Re(`ar$`)})
ok = td.Cmp(t,
got,
td.Any(td.HasPrefix("xxx"), regOps, td.HasSuffix("zip")),
"check at least one operator matches value %s", got)
fmt.Println(ok)
// Output:
// true
// false
// true
CmpAny shortcut
func CmpAny(t TestingT, got any, expectedValues []any, args ...any) bool
CmpAny is a shortcut for:
td.Cmp(t, got, td.Any(expectedValues...), args...)
See above for details.
Returns true if the test is OK, false if it fails.
If t is a *T then its Config field is inherited.
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.
