Go 接口嵌套组合的使用方法

package rocket

import (
    "code.byted.org/ecom/compass_data_index/driver"
    "code.byted.org/ecom/compass_data_index/service"
)

type IRocketFetcher interface {
    service.BasicInfoService
    driver.INavigatorDriver
}

type RocketFetcher struct {
    service.BasicInfoService
    driver.INavigatorDriver
}

func NewRocketFetcher() *RocketFetcher {
    return &RocketFetcher{
        &service.BasicInfoServiceImpl{},
        &driver.NavigatorDriver{},
    }
}

gomock 测试 stub 代码生成

使用 -aux_files 指定内嵌接口的 pkg1=path1,pkg2=path2. 需要注意的是, pkg1 / pkg2 不能跟被测接口的包相同!
(may be mockgen's assumptions!)

-aux_files rocket=service/basic_info_service.go,rocket=driver/navigator_driver.go

一个 Makefile 的例子:

PROJECTNAME=$(shell basename "$(PWD)")
all: format test

format:
    find . -name '*.go' | xargs goimports -w

test:
    go test -v -cover ./...

#test report
test_report:
    go test -v -cover -json ./...  | go-test-report -t "Test Report"



#gomock
mockgen_navigator_driver:
    mockgen -source=./driver/navigator_driver.go -destination ./driver/navigator_driver_mock.go -package driver

mockgen_rocket_fetcher:
    mockgen -source=./rocket/rocket_driver.go -destination ./rocket/rocket_driver_mock.go -package rocket -aux_files rocket=service/basic_info_service.go,rocket=driver/navigator_driver.go

mockgen_basic_info_service:
    mockgen -source=./service/basic_info_service.go -destination ./service/basic_info_service_mock.go -package service
