We will also provide insights on integrating Postman collections in a Jenkins pipeline, allowing for seamless automation and integration in your Continuous Integration Continuous Deployment (CICD) process.

Step 1: Creating a Postman Collection

The first step in setting up Postman API Automation is to create a Postman collection. A Postman collection is a container that holds all your API endpoints, requests, tests, and other configurations. To create a collection, follow these steps:

  1. Launch Postman and sign in to your Postman account (or create a new account if you don’t have one).
  2. In the Postman app, click on the “New” button in the top-left corner and select “Collection”.
  3. Enter a name for your collection and click “Save”.
  4. You can now start adding requests and tests to your collection by clicking on the collection name in the left sidebar and then clicking the “Add request” button.

Step 2: Configuring Test Scripts

Once you have created your Postman collection, you can configure test scripts to automate the testing process. Test scripts allow you to verify the response received from API endpoints and validate the data. To configure test scripts:

  1. Select a request in your collection.
  2. In the request window, click on the “Tests” tab.
  3. Write your test script using JavaScript syntax. You can use Postman’s built-in test snippets, as well as custom scripts tailored to your specific testing requirements.
  4. Save your test script.

Step 3: Executing Tests with Newman

After configuring the test scripts in your Postman collection, you can use Newman, Postman’s command-line tool, to execute the tests. Newman allows you to run your collection and view the test results in a command-line interface. Follow these steps to execute tests with Newman:

  1. Ensure Newman is installed on your system. If not, install it by running the command: npm install -g newman.
  2. Export your Postman collection as a JSON file by clicking on the ellipsis icon (…) next to your collection’s name in the Postman app, and selecting “Export”.
  3. In your command-line interface, navigate to the directory where you saved the JSON file.
  4. Execute the tests by running the command: newman run <collection.json>, replacing <collection.json> with the name of your JSON file.
  5. Newman will run the tests and display the results in the command-line interface, providing valuable insights into the success and failure of each test.
  6. If you want your report in HTML format, follow below method:

· npm install -g newman-reporter-html (this is for installing html reporter package)

· After that run the same report:

· Newman run “Path of the file” -r html(This create the html report)

Example: newman run AdminOperationsCollection.json -r html

Step 4: Integrating Postman Collections in Jenkins Pipeline

To further streamline your automated testing process, you can integrate Postman collections in a Jenkins pipeline. This integration allows for continuous testing as part of your CICD process. Here’s how you can do it:

  1. Open your Jenkins dashboard and navigate to your desired pipeline or create a new one.
  2. Add a build step or stage to execute the Newman command.
  3. Specify the path to your Postman collection JSON file and any other required parameters in the build step or stage configuration.
  4. Save the configuration and trigger the pipeline.
  5. Jenkins will now execute your Postman collection tests using Newman as part of your CICD process, providing automated and reliable API testing.

By following these steps, you can easily set up Postman API Automation with Newman and seamlessly integrate it into your CICD process. This integration empowers you to automate API testing, improve the efficiency of your DevOps workflow, and ensure the reliable delivery of high-quality software products.
