Step-by-Step Tutorial: Automating API Testing with Postman

1. Understanding the API Endpoints

• Watch the video to understand the different API endpoints available for testing.
• Take note of the API endpoints for adding a book, retrieving book details, and deleting a book.

2. Setting Dynamic Base Server URL

• Learn how to dynamically set the base server URL by using global variables or environment variables in Postman.
• Understand the importance of setting dynamic URLs to ensure flexibility when switching between servers.

3. Data-Driving Test Data

• Learn how to data drive test data in Postman to efficiently test multiple scenarios with different data inputs.
• Understand the concept of data-driven testing for thorough API testing.

4. Automating Validations

• Explore how to automate validations in Postman to compare JSON responses for different API requests.
• Learn how to automate the process of comparing responses to determine if the test is passing or failing.

5. Building Automation Scripts

• Understand the importance of building automation scripts for API testing to streamline the testing process.
• Create automation scripts that can perform tasks such as adding a book, retrieving book details, and deleting a book automatically.

6. Adding a New Collection and Request

• In Postman, add a new collection for the API requests you want to automate.
• Create a new request for adding a book with the appropriate base URL and request method (POST).

7. Sending Secure Data

• Understand the difference between using GET and POST methods in API requests.
• Send secure data using the POST method to ensure sensitive information is transmitted securely.

8. Deleting a Book

• Create a request for deleting a book from the library using the appropriate base URL and request method (POST).
• Use the raw JSON option to include the book ID in the request body for deletion.

9. Automating Response Validation

• Automate the validation of responses to ensure the correct book is deleted successfully.
• Check the response status code to confirm if the request was processed successfully (status 200).

10. Handling Error Messages

• Understand how to handle error messages when attempting to delete a book that does not exist in the database.
• Learn how to interpret error messages returned by the API for better troubleshooting.

11. Exploring Automation Scenarios

• Explore the potential for automation in API testing beyond the basic CRUD operations.
• Understand the scope for automation testing in various scenarios using Postman.

12. Continuous Learning and Automation

• Stay patient and continue learning about automation testing using Postman.
• Explore different automation scenarios derived from the API requests demonstrated in the tutorial.

By following these steps, you can enhance your understanding of API testing with Postman and automate various testing scenarios efficiently.
