Automating test suites in Postman can significantly streamline your testing process by allowing you to reuse variables across multiple requests. This guide will walk you through the steps to save a header value from one request and use it in subsequent requests within the same collection.
Steps to Save and Use a Header Value in Postman
Step 1: Capture the Header Value
To capture a header value from the response of the first request, you need to use the Postman scripting capabilities. The following script captures the header value and stores it as a global variable:
pm.test("First request", function() {
let headerValue = pm.response.headers.get("Number");
pm.globals.set("Number", headerValue);
});This script should be added to the Tests tab of your first request. It retrieves the header named Number from the response and sets it as a global variable named Number.
Step 2: Use the Stored Header Value in Subsequent Requests
In your subsequent requests, you can utilize the stored global variable by referencing it in the headers section. Here’s how you can do it:
- Navigate to the Headers section of the request.
- Add a new header with
Numberas the key and{{Number}}as the value.
This ensures that the header value captured in the first request is used in the subsequent requests.
Additional Tips
To ensure your scripts work smoothly, it’s essential to keep your Postman scripts and environment variables up-to-date. Regularly check the Postman documentation for any updates or changes in scripting methods.
Leveraging Test Automation with Repeato
While Postman is excellent for API testing, comprehensive app testing requires a more robust solution. This is where Repeato comes into play. Repeato is a no-code test automation tool for iOS and Android that helps you create, run, and maintain automated tests for your apps with ease. Leveraging computer vision and AI, Repeato ensures fast and efficient test execution.
Repeato’s intuitive test recorder and no-code interface make it accessible for all testers, while its scripting interface caters to advanced use cases. Additionally, Repeato supports testing websites inside an Android emulator or device, with explicit web testing support slated for release later this summer.
