Object is to create API integration tests using Postman and execute it in AWS using AWS CodeBuild.

Development

• Create Postman Test Collection with Dynamic data set
• Create Postman Environment
• Export Collection and Postman to Local Drive.
• Create buildspec.yml

version: 0.2

phases:
  pre_build:
    commands:
      - npm install -g newman
      - npm install -g newman-reporter-html

  build:
    commands:
      - newman run -r html,cli backend.postman_collection.json -e backend-Dev.postman_environment.json --reporter-html-export apireport.html

artifacts:
  files:
    - apireport.html

AWS

• Create S3 bucket to store the collection and environment json files

aws s3 mb s3://backend-api-test-collections

• Push collection, environment json and buildspec.yml files to the bucket

aws s3 cp backend.postman_collection.json s3://backend-api-test-collections/postman-env-files/backend.postman_collection.json
aws s3 cp buildspec.yml s3://backend-api-test-collections/postman-env-files/buildspec.yml

• Create S3 bucket to store the test results

aws s3 mb s3://backend-api-test-results

• Create AWS CodeBuild

• Note that Source Provider is Amazon S3
• Choose buildspec.yml as buildspec file

• Artifact — to store results

• Trigger the AWS CodeBuild

• Navigate to backend-api-test-results S3 bucket to find the html report apireport.html
• During the creation of CodeBuild, you can create log group to send execution results to Cloudwatch
