组合技 Drone + godog + Mattermost

当有需求要在k8s上透过drone定期跑godog进行BDD测试，并将测试结果推送到mattermost时，怎麽办呢？

首先需求拆解：

• 在k8s上跑Drone -> [Day 15] Drone - Runner in k8s 安装设定
• 在Drone上定期跑 -> Drone cron job [Day 13] Oops！Drone - Cron Jobs
  
• 推送结果到Mattermost -> 使用Drone Plugin[Day 22] Mattermost - with Drone Plugin

Create Your Pipeline

在BDD专案内，制作你的pipeline
以下以Drone为范例

kind: pipeline
type: kubernetes
name: bdd

steps:
- name: godog solo basic.feature
  image: rain123473/godog:v0.11.0
  commands:
    - cd solo
    - godog run features/basic.feature

- name: send notification
  when:
    status:
    - success
  image: plugins/slack
  settings:
    webhook:
      from_secret: bdd
    channel: ithome-bdd
    username: drone
    icon_url: https://img.icons8.com/color/2x/good-pincode.png
    template: >
        [DEV] BDD test build {{build.link}} succeeded. Good job.

- name: send failure notification
  when:
    status:
    - failure
  image: plugins/slack
  settings:
    webhook:
      from_secret: bdd
    channel: ithome-bdd
    username: drone
    icon_url: https://img.icons8.com/color/2x/high-priority.png
    template: >
       {{#success build.status}}
        [DEV] BDD test build {{build.link}} succeeded. Good job.
       {{else}}
        [DEV] BDD build {{build.link}} failed. Fix me please.
       {{/success}}

在drone yaml设定，可以使用

  when:
    status:

来绑定此step的状态，所以可以从step

• send notification -> 当bdd测试「成功」寄送通知
• send failure notification -> 当bdd测试「失败」寄送通知

看得出来唷！

Drone Cron

再次提醒一下
Cron Jobs 的时区是依照 UTC(Universal Time Coordinated)，所以需要自己在转换一下时间
若你的需求是要台湾时间22:00~04:00，每小时触发的话，不能打22-04唷!要改成14-20才正确！

drone cron add "my/bdd-repo" "bdd-nighty-test" "0 0 14-20 * * *" --branch master

之後就能在Mattermost该channel内看到效果罗

以上就完成上述之需求(在k8s上透过drone定期跑godog进行BDD测试，并将测试结果推送到mattermost)了，今天就这样子拉～
