The framework and its supporting tools can be installed by running the following commands:
$ go get github.com/golang/mock/gomock $ go install github.com/golang/mock/mockgen
The mockgen tool is responsible for analyzing either individual Go files or entire packages and generating mocks for all (or specific) interfaces that are defined within them. It supports two modes of operation:
- Source code scanning: We pass a Gi file to mockgen, which is then parsed in order to detect interface definitions.
- Reflection-assisted mode ...
