You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mock_channels_manager.go
    path of file: ./repos/milvus/internal/proxy
    
    the code of the file until where you have to start completion: // Code generated by mockery v2.32.4. DO NOT EDIT.

package proxy

import (
	msgstream "github.com/milvus-io/milvus/pkg/mq/msgstream"
	mock "github.com/stretchr/testify/mock"
)

// MockChannelsMgr is an autogenerated mock type for the channelsMgr type
type MockChannelsMgr struct {
	mock.Mock
}

type MockChannelsMgr_Expecter struct {
	mock *mock.Mock
}

func (_m *MockChannelsMgr) EXPECT() *MockChannelsMgr_Expecter {
	return &MockChanne
    
func (_m *MockChannelsMgr) getVChannels(collectionID int64) ([]string, error) {
	ret := _m.Called(collectionID)

	var r0 []string
	var r1 error
	if rf, ok := ret.Get(0).(func(int64) ([]string, error)); ok {

		}
	}

	if rf, ok := ret.Get(1).(func(int64) error); ok {
