func NotNil() TestDeep
NotNil
operator checks that data is not nil
(or is a non-nil
interface, containing a non-nil
pointer.)
See also NotNil godoc.
t := &testing.T{}
var got fmt.Stringer = &bytes.Buffer{}
// nil value can be compared directly with Not(nil), no need of NotNil() here
ok := Cmp(t, got, Not(nil))
fmt.Println(ok)
// But it works with NotNil() anyway
ok = Cmp(t, got, NotNil())
fmt.Println(ok)
got = (*bytes.Buffer)(nil)
// In the case of an interface containing a nil pointer, comparing
// with Not(nil) succeeds, as the interface is not nil
ok = Cmp(t, got, Not(nil))
fmt.Println(ok)
// In this case NotNil() fails
ok = Cmp(t, got, NotNil())
fmt.Println(ok)
// Output:
// true
// true
// true
// false
func CmpNotNil(t TestingT, got interface{}, args ...interface{}) bool
CmpNotNil is a shortcut for:
Cmp(t, got, NotNil(), 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 CmpNotNil godoc.
