示例1: checkExerciseRepository
// checkExerciseRegistry takes the registry through all of its operations,
// carrying out generic checks.
func checkExerciseRepository(t *testing.T, ctx context.Context, repository distribution.Repository) {
// TODO(stevvooe): This would be a nice testutil function. Basically, it
// takes the registry through a common set of operations. This could be
// used to make cross-cutting updates by changing internals that affect
// update counts. Basically, it would make writing tests a lot easier.
