組合技 Drone + godog + Mattermost

當有需求要在k8s上透過drone定期跑godog進行BDD測試，並將測試結果推送到mattermost時，怎麼辦呢？

首先需求拆解：

• 在k8s上跑Drone -> [Day 15] Drone - Runner in k8s 安裝設定
• 在Drone上定期跑 -> Drone cron job [Day 13] Oops！Drone - Cron Jobs
  
• 推送結果到Mattermost -> 使用Drone Plugin[Day 22] Mattermost - with Drone Plugin

Create Your Pipeline

在BDD專案內，製作你的pipeline
以下以Drone為範例

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設定，可以使用

  when:
    status:

來綁定此step的狀態，所以可以從step

• send notification -> 當bdd測試「成功」寄送通知
• send failure notification -> 當bdd測試「失敗」寄送通知

看得出來唷！

Drone Cron

再次提醒一下
Cron Jobs 的時區是依照 UTC(Universal Time Coordinated)，所以需要自己在轉換一下時間
若你的需求是要台灣時間22:00~04:00，每小時觸發的話，不能打22-04唷!要改成14-20才正確！

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

之後就能在Mattermost該channel內看到效果囉

以上就完成上述之需求(在k8s上透過drone定期跑godog進行BDD測試，並將測試結果推送到mattermost)了，今天就這樣子拉～
