Introduction

As a developer or tester, you often need to monitor API responses for specific text patterns to ensure that your application is functioning correctly. Postman, a popular API testing tool, provides a range of features to help you achieve this. In this article, we will explore how to monitor for a particular text in API responses and get notified in Postman.

API Testing with Postman

Postman is a powerful tool for testing APIs. It allows you to send HTTP requests, view responses, and analyze the data in a user-friendly interface. With Postman, you can test APIs quickly and efficiently, saving you time and effort.

Monitoring API Responses

Monitoring API responses is an essential part of API testing. It helps you ensure that your application is functioning correctly and that the API is returning the expected data. In this section, we will explore how to monitor for a particular text in API responses in Postman.

Using the "Tests" Tab in Postman

Postman provides a "Tests" tab where you can write JavaScript code to test API responses. You can use this tab to monitor for specific text patterns in API responses.

To use the "Tests" tab, follow these steps:

  1. Open Postman and create a new request.
  2. Send the request to the API endpoint you want to test.
  3. Switch to the "Tests" tab.
  4. Write JavaScript code to test the API response.

Here is an example of how you can use the "Tests" tab to monitor for a particular text in API responses:

pm.test("Product name is PARLE", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.productname).to.equal("PARLE");
});

In this example, we are testing if the product name in the API response is "PARLE". If the product name is not "PARLE", the test will fail.

Using a Pre-Request Script in Postman

Another way to monitor API responses in Postman is by using a pre-request script. A pre-request script is a JavaScript code that runs before the request is sent to the API endpoint.

To use a pre-request script, follow these steps:

  1. Open Postman and create a new request.
  2. Click on the "Pre-request Script" tab.
  3. Write JavaScript code to test the API response.

Here is an example of how you can use a pre-request script to monitor for a particular text in API responses:

var jsonData = pm.response.json();
if (jsonData.productname !== "PARLE") {
    pm.environment.set("product_name", "Error: Product name is not PARLE");
}

In this example, we are testing if the product name in the API response is "PARLE". If the product name is not "PARLE", we set an environment variable "product_name" to "Error: Product name is not PARLE".

Using a Postman Collection

Postman collections are a way to organize your API tests. You can create a collection and add multiple requests to it. Postman collections also provide a range of features to help you manage your API tests.

To use a Postman collection, follow these steps:

  1. Open Postman and create a new collection.
  2. Add multiple requests to the collection.
  3. Use the "Tests" tab or a pre-request script to monitor for specific text patterns in API responses.

Here is an example of how you can use a Postman collection to monitor for a particular text in API responses:

// Collection: API Testing
// Request: Get Product Details
// Tests:
pm.test("Product name is PARLE", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.productname).to.equal("PARLE");
});

In this example, we are testing if the product name in the API response is "PARLE". If the product name is not "PARLE", the test will fail.

Getting Notified in Postman

Postman provides a range of features to help you get notified when API tests fail. You can use the "Tests" tab, a pre-request script, or a Postman collection to monitor for specific text patterns in API responses.

To get notified in Postman, follow these steps:

  1. Open Postman and create a new request.
  2. Use the "Tests" tab or a pre-request script to monitor for specific text patterns in API responses.
  3. Set up a notification in Postman.

Here is an example of how you can set up a notification in Postman:

// Collection: API Testing
// Request: Get Product Details
// Tests:
pm.test("Product name is PARLE", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.productname).to.equal("PARLE");
});
// Notification:
pm.notification("Error: Product name is not PARLE", "Error: Product name is not PARLE");

In this example, we are testing if the product name in the API response is "PARLE". If the product name is not "PARLE", we set up a notification with the message "Error: Product name is not PARLE".

Conclusion

Monitoring API responses is an essential part of API testing. Postman provides a range of features to help you monitor for specific text patterns in API responses and get notified when tests fail. In this article, we explored how to use the "Tests" tab, a pre-request script, and a Postman collection to monitor for a particular text in API responses and get notified in Postman.

Best Practices

Here are some best practices to keep in mind when monitoring API responses in Postman:

  • Use the "Tests" tab or a pre-request script to monitor for specific text patterns in API responses.
  • Set up notifications in Postman to get notified when tests fail.
  • Use Postman collections to organize your API tests.
  • Use environment variables to store data that is used across multiple requests.
