Ptr

func Ptr(val any) TestDeep

Ptr is a smuggler operator. It takes the address of data and compares it to val.

val depends on data type. For example, if the compared data is an *int, one can have:

num := 12
td.Cmp(t, &num, td.Ptr(12)) // succeeds

as well as an other operator:

num := 3
td.Cmp(t, &num, td.Ptr(td.Between(3, 4)))

TypeBehind method returns the reflect.Type of a pointer on val, except if val is a TestDeep operator. In this case, it delegates TypeBehind() to the operator and returns the reflect.Type of a pointer on the returned value (if non-nil of course).

See also PPtr and Shallow.

Example

Base example 
	t := &testing.T{}

	got := 12

	ok := td.Cmp(t, &got, td.Ptr(12))
	fmt.Println(ok)

	ok = td.Cmp(t, &got, td.Ptr(td.Between(4, 15)))
	fmt.Println(ok)

	// Output:
	// true
	// true

CmpPtr shortcut

func CmpPtr(t TestingT, got, val any, args ...any) bool

CmpPtr is a shortcut for:

td.Cmp(t, got, td.Ptr(val), 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.

See also CmpPtr godoc.

Example

Base example 
	t := &testing.T{}

	got := 12

	ok := td.CmpPtr(t, &got, 12)
	fmt.Println(ok)

	ok = td.CmpPtr(t, &got, td.Between(4, 15))
	fmt.Println(ok)

	// Output:
	// true
	// true

T.Ptr shortcut

func (t *T) Ptr(got, val any, args ...any) bool

Ptr is a shortcut for:

t.Cmp(got, td.Ptr(val), 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 T.Ptr godoc.

Example

Base example 
	t := td.NewT(&testing.T{})

	got := 12

	ok := t.Ptr(&got, 12)
	fmt.Println(ok)

	ok = t.Ptr(&got, td.Between(4, 15))
	fmt.Println(ok)

	// Output:
	// true
	// true
