Map
func Map(model interface{}, expectedEntries MapEntries) TestDeep
Map
operator compares the contents of a map against the non-zero
values of model (if any) and the values of expectedEntries.
model must be the same type as compared data.
expectedEntries can be nil
, if no zero entries are expected and
no TestDeep operator are involved.
During a match, all expected entries must be found and all data
entries must be expected to succeed.
got := map[string]string{
"foo": "test",
"bar": "wizz",
"zip": "buzz",
}
td.Cmp(t, got, td.Map(
map[string]string{
"foo": "test",
"bar": "wizz",
},
td.MapEntries{
"zip": td.HasSuffix("zz"),
}),
) // succeeds
TypeBehind
method returns the reflect.Type
of model.

CmpMap shortcut
func CmpMap(t TestingT, got, model interface{}, expectedEntries MapEntries, args ...interface{}) bool
CmpMap is a shortcut for:
td.Cmp(t, got, td.Map(model, expectedEntries), 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.
