.NET WEBAPI core testing using postman

             .NET WEBAPI core testing using postman

Step 1: Launch Postman

1. If you haven't already installed Postman, download and install it from the official website.
2. Once installed, open Postman.

Step 2: Import or Create a Request

1. You can import an existing request collection or create a new request.
2. To create a new request, click on the "New" button in the top-left corner and select "Request".

Step 3: Set Up Your Request

1. Enter the request URL in the address bar.
2. Choose the HTTP method (GET, POST, PUT, DELETE) from the dropdown menu.
3. Optionally, add request headers, request body, query parameters, etc., depending on your API endpoint requirements.

Step 4: Send the Request

1. Click on the "Send" button to send the request.
2. Postman will display the response received from the API server.

Step 5: Inspect the Response

1. Inspect the response body to ensure it contains the expected data.
2. Check the response status code to verify that the request was successful (status code 200) or to identify any errors.

Step 6: Testing Different Endpoints

1. Repeat steps 2-5 for different API endpoints you want to test.
2. Change the request URL, HTTP method, headers, and body as necessary for each endpoint.

Step 7: Testing Authorization (if applicable)

1. If your API requires authorization (e.g., JWT token), include the necessary authorization headers in your request.
2. Verify that you can access authorized endpoints and that unauthorized requests are rejected.

Step 8: Save Your Requests (Optional)

1. To save your requests for future use, click on the "Save" button and choose a collection to save your request in.

Step 9: Running Tests

1. Postman allows you to create and run tests to automate the validation of your API responses.
2. To create tests, switch to the "Tests" tab below the request editor and write your test scripts using JavaScript.
3. Click on the "Send" button to run the request and execute the tests.
4. Postman will display the test results in the "Test Results" pane.

Step 10: Organizing Your Requests (Optional)

1. You can organize your requests into folders within Postman collections to keep them structured.
2. Create new folders by clicking on the "New Folder" button in the sidebar.

Additional Tips:

• Use environment variables in Postman to manage different environments (e.g., development, staging, production).
• Use Postman's documentation feature to generate API documentation automatically based on your requests.
