.NET WEBAPI core testing using postman
Step 1: Launch Postman
- If you haven't already installed Postman, download and install it from the official website.
- Once installed, open Postman.
Step 2: Import or Create a Request
- You can import an existing request collection or create a new request.
- To create a new request, click on the "New" button in the top-left corner and select "Request".
Step 3: Set Up Your Request
- Enter the request URL in the address bar.
- Choose the HTTP method (GET, POST, PUT, DELETE) from the dropdown menu.
- Optionally, add request headers, request body, query parameters, etc., depending on your API endpoint requirements.
Step 4: Send the Request
- Click on the "Send" button to send the request.
- Postman will display the response received from the API server.
Step 5: Inspect the Response
- Inspect the response body to ensure it contains the expected data.
- 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
- Repeat steps 2-5 for different API endpoints you want to test.
- Change the request URL, HTTP method, headers, and body as necessary for each endpoint.
Step 7: Testing Authorization (if applicable)
- If your API requires authorization (e.g., JWT token), include the necessary authorization headers in your request.
- Verify that you can access authorized endpoints and that unauthorized requests are rejected.
Step 8: Save Your Requests (Optional)
- 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
- Postman allows you to create and run tests to automate the validation of your API responses.
- To create tests, switch to the "Tests" tab below the request editor and write your test scripts using JavaScript.
- Click on the "Send" button to run the request and execute the tests.
- Postman will display the test results in the "Test Results" pane.
Step 10: Organizing Your Requests (Optional)
- You can organize your requests into folders within Postman collections to keep them structured.
- 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.
