QA Process

1. Checkout sast project locally
2. Import go module from this branch:

sast ❯ go get gitlab.com/gitlab-org/security-products/analyzers/common/orchestrator/v2@force-uid-for-nodejs-projects
go: finding gitlab.com/gitlab-org/security-products/analyzers/common/orchestrator/v2 force-uid-for-nodejs-projects
go: downloading gitlab.com/gitlab-org/security-products/analyzers/common/orchestrator/v2 v2.0.0-20190919192349-143432b1d757
go: extracting gitlab.com/gitlab-org/security-products/analyzers/common/orchestrator/v2 v2.0.0-20190919192349-143432b1d757

3. Build sast: GO111MODULE=on GOOS=linux go build -o sast
4. Build sast container: docker build -t sast . 5a. Test container against gitlab-org/gitlab project (this takes about 15min locally):

docker run -it --volume "$PWD":/code --volume /var/run/docker.sock:/var/run/docker.sock --env SAST_DEFAULT_ANALYZERS=nodejs-scan saast /app/bin/run /code

5b. If you dont want to wait 15min you can "cheat" like this:

touch shared/foo.js
docker run -it --volume "$PWD/shared":/code --volume /var/run/docker.sock:/var/run/docker.sock --env SAST_DEFAULT_ANALYZERS=nodejs-scan saast /app/bin/run /code
