What are some effective tools for testing input validation?

There are several tools you can use for testing input validation, such as Postman, JMeter, and Selenium. Each has its strengths depending on your needs.

Can you explain how Postman can help with input validation?

Postman allows you to create and send HTTP requests to your API, making it easy to test various input scenarios and validate responses.

What about JMeter? How does it compare to Postman?

JMeter is more focused on performance testing, but it can also be used for input validation by simulating multiple users and testing how your application handles various inputs.

Are there any specific features in Selenium that assist with input validation?

Selenium is primarily for automated browser testing, but you can use it to fill out forms and validate input fields by checking for expected error messages or successful submissions.
