MapEach
func MapEach(expectedValue any) TestDeep
MapEach operator has to be applied on maps. It compares each value
of data map against expectedValue. During a match, all values have
to match to succeed.
got := map[string]string{"test": "foo", "buzz": "bar"}
td.Cmp(t, got, td.MapEach("bar")) // fails, coz "foo" ≠ "bar"
td.Cmp(t, got, td.MapEach(td.Len(3))) // succeeds as values are 3 chars long
See also MapEach godoc.
Examples
Map example
t := &testing.T{}
got := map[string]int{"foo": 12, "bar": 42, "zip": 89}
ok := td.Cmp(t, got, td.MapEach(td.Between(10, 90)),
"checks each value of map %v is in [10 .. 90]", got)
fmt.Println(ok)
// Output:
// true
TypedMap example
t := &testing.T{}
type MyMap map[string]int
got := MyMap{"foo": 12, "bar": 42, "zip": 89}
ok := td.Cmp(t, got, td.MapEach(td.Between(10, 90)),
"checks each value of typed map %v is in [10 .. 90]", got)
fmt.Println(ok)
ok = td.Cmp(t, &got, td.MapEach(td.Between(10, 90)),
"checks each value of typed map pointer %v is in [10 .. 90]", got)
fmt.Println(ok)
// Output:
// true
// true
CmpMapEach shortcut
func CmpMapEach(t TestingT, got, expectedValue any, args ...any) bool
CmpMapEach is a shortcut for:
td.Cmp(t, got, td.MapEach(expectedValue), 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.
