如果任何测试失败，如何通过掌舵运行Postman测试用例并回滚到上一个成功的版本 [英] How to run Postman test cases by helm and rollback to last successful version if any test fail

问题描述

我正在使用Helm kubernetes部署，我想在最终部署之前运行邮递员测试用例，如果任何测试用例失败，则回滚(或保留当前的部署，例如Blue-Green部署). 如何实现呢?

I am using Helm kubernetes deployment and I want to run the postman test cases before a final deployment, and if any test case fails then rollback (or retain the current deployment like Blue-Green deployment). How to achieve this?

推荐答案

我通过实现了预期的行为Helm Chart Tests 和 postman/newman Docker映像.

用于测试执行的我的Helm模板:

My Helm template for the test execution:

apiVersion: v1
kind: Pod
metadata:
  name: API Test
  annotations:
    "helm.sh/hook": test-success
spec:
  containers:
    - name: PostmanTest
      image: postman/newman:latest
      args:
        - run
        - <url-to-postman-collection>
        # In case you need to define the hostname in the collection
        # Use {{baseUrl}} in the request URL
        - --env-var
        - baseUrl=<kubernetes-host-name>

安装头盔图表后，可以使用以下命令执行测试

After install the helm chart the tests can be executed with
