PPtr

func PPtr(val interface{}) TestDeep

PPtr is a smuggler operator. It takes the address of 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
pnum = &num
td.Cmp(t, &pnum, td.PPtr(12)) // succeeds

as well as an other operator:

num := 3
pnum = &num
td.Cmp(t, &pnum, td.PPtr(td.Between(3, 4))) // succeeds

It is more efficient and shorter to write than:

td.Cmp(t, &pnum, td.Ptr(td.Ptr(val))) // succeeds too

TypeBehind method returns the reflect.Type of a pointer on 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 a pointer on the returned value (if non-nil of course).

Example

Base example

CmpPPtr shortcut

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

CmpPPtr is a shortcut for:

td.Cmp(t, got, td.PPtr(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 CmpPPtr godoc.
