NotNil

func NotNil() TestDeep

NotNil operator checks that data is not nil (or is a non-nil interface, containing a non-nil pointer.)

got := &Person{}
td.Cmp(t, got, td.NotNil()) // succeeds
td.Cmp(t, got, td.Not(nil)) // succeeds too, but be careful it is first
// because of got type *Person ≠ untyped nil so prefer NotNil()

but:

var got fmt.Stringer = (*bytes.Buffer)(nil)
td.Cmp(t, got, td.NotNil()) // fails
td.Cmp(t, got, td.Not(nil)) // succeeds, as the interface is not nil

Example

Base example

CmpNotNil shortcut

func CmpNotNil(t TestingT, got interface{}, args ...interface{}) bool

CmpNotNil is a shortcut for:

td.Cmp(t, got, td.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.
