1. GO 환경 변수 설정
GOPATH 환경 변수는 workspace 의 위치를 지정
GOROOT 환경 변수는는 현재 만들고있는 GO 프로그램의 위치다. go get으로 패키지를 설치하고, go build로 빌드를 할때 GOROOT와 더불어 패키지와 명령들을 찾을 위치를 지정
ex)
$ export GOPATH=$HOME/cpi/bosh-google-cpi-release
$ export GOROOT=/usr/local/go
$ export PATH=$PATH:GOPATH/bin
1. 패키지 단위 테스트 방법
$ go test -v bosh-google-cpi/action/
2. 패키지 단위 테스트 HTML 변환 방법
$ go test bosh-google-cpi/action/ -coverprofile=c.out -covermode=count -v
$ go tool cover -html=c.out
$ sudo 권한의 tmp 파일 위치에 html 파일이 생성 된다.
3. 통합 테스트 방법_GCP 환경 설정
전제 조건 – GCP 콘솔 화면에서 환경 설정이 되어 있어야 한다.
전제 조건 – GCP SDK CLI가 설치가 되어 있어야 한다.
l 실제 환경 설정이 존재 하지 않으면 에러가 발생 하지만, 이 정보들을 사용 하진 않는 것 같다.

1. 통합 테스트 방법_실제 실행 되는 데이터들이 존재 하는 소스 파일
bosh-google-cpi-release/src/bosh-google-cpi/integration/config.go에 위치 한다.
변수 값 설정
envRequired -> 반드시 필요한 값 설정 하지 않으면 에러 발생.
envOrDefault -> 환경 변수가 존재 하지 않으면 Default 값으로 설정 된다.

3. 통합 테스트 실행
$ cd bosh-google-cpi-release/src/bosh-google-cpi/integration
$ go test -x -v -timeout 180m
4. 통합 테스트 주의 사항
GO TEST 실행 시 Default time이 10분 -> 통합 테스트는 1시간이 넘게 걸리는데 10분이 지나면 Time out 실패 에러 메시지가 발생 한다.
l 해결 방법 -timeout 180m를 go test 명령어에 붙여 실행 한다.
GO TEST 실행 시 권한 문제가 발생 할 경우
$ gcloud auth application-default login 명령어를 통해 auth 로그인을 실행 하면 된다.
