Integrating Postman with Jenkins

Understanding the Integration

Integrating Postman with Jenkins can significantly enhance your API testing and automation workflows. By integrating these tools, you can

• Automate API Testing: Execute Postman collections as part of your Jenkins pipeline.

• Trigger Jenkins Jobs: Use Postman to trigger Jenkins jobs based on specific API responses or events.

• Share and Collaborate: Easily share and collaborate on API tests within your team.

• Continuous Integration and Delivery: Incorporate API testing into your CI/CD pipeline.

Run a Manage Environment in Postman

1.Click the Environment quick look (eye button) in the top right of Postman and click Edit next to Global.

2.Add a variable named my_variable and give it an initial value of Hello—click Save and close the environment modal.

3.Open a new request tab and enter https://postmanecho.com/get?var={{my_variable}} as the URL. However over the variable name and you'll see the value.

4.Send the request. In the response, you'll see that Postman sent the variable value to the API. Try changing the value in the Environment quick look and sending the request again.
