How to run a pipeline step only when pushing to a new branch?

2021-01-07

GitHub sends push hook when pushing to a new branch and merging a PR. How can we distinguish between them?

We are running integration test by triggering a downstream build when a PR is merged into specific branches. In the downstream repository, we pull all the docker images which has been built and pushed from upstream. The thing is we also used the drone-convert-pathschanged to only publish what modules has been changed.

So, what happens when pushing to a new release-* branch?

How to perform integration testing in Go?

2020-09-29

Integration testing can be triggered by using Drone downstream plugin:

 1steps:
 2- name: trigger
 3  image: plugins/downstream:linux-amd64
 4  settings:
 5    params:
 6    - COMMIT_BRANCH=${DRONE_COMMIT_BRANCH}
 7    repositories:
 8    - repo/integration-test@${DRONE_COMMIT_BRANCH}
 9    server: https://drone.example.com
10    token:
11      from_secret: drone_token

It can be separated with unit tests by using build tags:

1// +build integration
2
3package webserver_test

Then we can write code to perform integration test as usual.
