+# Tests for custom package names
+
+This directory contains test for mockgen generating mocks when imported package
+name does not match import path suffix. For example, package with name "client"
+is located under import path "github.com/golang/mock/mockgen/tests/custom_package_name/client/v1".
+
+Prior to this patch:
+
+ $ go generate greeter/greeter.go
+ 2018/03/05 22:44:52 Loading input failed: greeter.go:17:11: failed parsing returns: greeter.go:17:14: unknown package "client"
+ greeter/greeter.go:1: running "mockgen": exit status 1
+
+This can be fixed by manually providing `-imports` flag, like `-imports client=github.com/golang/mock/mockgen/tests/custom_package_name/client/v1`.
+But, mockgen should be able to automatically resolve package names in such situations.
+
+With this patch applied:
+
+ $ go generate greeter/greeter.go
+ $ echo $?
+ 0
+
+Mockgen runs successfully, produced output is equal to [greeter_mock_test.go](greeter/greeter_mock_test.go) content.
