func Diff ¶

func Diff[T any](want T, got T, opts ...cmp.Option) string

Diff is just like cmp.Diff but it forces got and want to have the same type and includes protocmp.Transform().

This will result in more informative compile-time errors. protocmp.Transform() is necessary for any protocol buffer comparison, and it correctly does nothing if the arguments that we pass in are hereditarily non-protobufs. So, for developer convenience, let's just always add it.

if you want to extend the defaults, take a look at: - "go.chromium.org/luci/common/testing/registry"

func Got ¶

func Got[T any](got T) *diffBuilder[T]

Got supports the got-before-want style, it can be used as:

if diff := Got(1).Want(2).Options(...).Diff(); diff != "" {
  ...
}
