NotZero

func NotZero() TestDeep

NotZero operator checks that data is not zero regarding its type.

  • nil is the zero value of pointers, maps, slices, channels and functions;
  • 0 is the zero value of numbers;
  • "” is the 0 value of strings;
  • false is the zero value of booleans;
  • zero value of structs is the struct with no fields initialized.

Beware that:

td.Cmp(t, AnyStruct{}, td.NotZero())          // is false
td.Cmp(t, &AnyStruct{}, td.NotZero())         // is true, coz pointer ≠ nil
td.Cmp(t, &AnyStruct{}, td.Ptr(td.NotZero())) // is false

Example

Base example

CmpNotZero shortcut

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

CmpNotZero is a shortcut for:

td.Cmp(t, got, td.NotZero(), 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 CmpNotZero godoc.
