Question

Azure Load Testing

Donna Ludwig 35

I'm new to Azure Load Testing and have an elementary question.

The Use Case: I have a https web page that has form field data , a reCAPTCHA verification check box, and a submit button. No input data comes from query parameters. We want to include submitting the page with input data in our load tests.

Question : Is Azure Load Testing capable of testing the above Use Case ? If so, can you please explain how? Thanks

Locked Question. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.

Azure Load Testing can submit the underlying HTTPS form request, but it does not run a real browser, execute page JavaScript, or solve reCAPTCHA. reCAPTCHA is intended to reject automation, so test a nonproduction environment with the provider’s test keys or an application-controlled bypass that can never be enabled in production. Record the form flow or create a JMeter script, capture any CSRF token and session cookie, and parameterize input fields from a CSV file. Send the POST request generated by the form, then add assertions for the expected status and content. If CAPTCHA cannot be bypassed safely, load-test the API below it and keep a separate, small browser-based functional test for the interface. Do not use a CAPTCHA-solving service or weaken the production control. That would measure bypass behavior rather than the application’s supported load capacity.
