# gomock
> This program creates mocks based on Go interface
> for example
> Running
```sh
gomock -s $GOROOT/src/io/io.go -n ReadCloser
```
> The Mock Created Is
```go
// Interface compatible with ReadCloser that contains
// the Mock function to access the Mock instance
type ReadCloserMockInterface interface {
io.ReadCloser
Mock() *ReadCloserMock
}
// function to create the mock
func NewReadCloserMock() ReadCloserMockInterface {
return &ReadCloserMock{}
}
// function to access the mock instance
// for example
// var myVar ReadCloser
// mock := NewReadCloserMock()
// mock.Mock().Callbackxxx = func(...)...{} // Modifies the default behavior of the mock function
// myVar = mock // Compatible interface!!
func (m *ReadCloserMock) Mock() *ReadCloserMock {
return m
}
// Mock for ReadCloser interface
type ReadCloserMock struct {
CallbackRead func(p []byte) (n int, err error)
CallbackClose func() (retVar0 error)
}
// Read function
func (m *ReadCloserMock) Read(p []byte) (n int, err error) {
if m.CallbackRead != nil {
return m.CallbackRead(p)
}
return n, err
}
// Close function
func (m *ReadCloserMock) Close() (retVar0 error) {
if m.CallbackClose != nil {
return m.CallbackClose()
}
return retVar0
}
```
