You can use bulkmockgen with go:generate comment.

package foo

	new(IBar),
}

Restriction

• Bulkmockgen is available for gomock's package mode. Source mode is currently not available.

Migrate from mockgen

There is a migration tool mockgen-to-bulkmockgen. You can rewrite //go:generate mockgen comments to bulkmockgen's all at once.

go install github.com/utgwkk/bulkmockgen/cmd/mockgen-to-bulkmockgen@latest

Note that this migration tool can't migrate external interface mocking.
