A more thorough explanation:

A beta-test agreement is a legal agreement between a software developer and a customer that allows the customer to use a software program before it is released to the public. This agreement is usually made to test the software in a "live" environment and to get feedback from the user.

Unlike regular software licenses, beta-test agreements have more limitations on liability and fewer warranties. The user is required to evaluate the software and provide feedback to the developer.

Suppose a software company has developed a new video editing software. Before releasing it to the public, they want to test it in a real-world environment. They offer a beta-test agreement to a group of customers who are interested in using the software. The customers can use the software for a limited time and provide feedback to the company. The company can use this feedback to improve the software before releasing it to the public.

Another example is a mobile app developer who wants to test their app before releasing it to the public. They offer a beta-test agreement to a group of users who can use the app and provide feedback. The developer can use this feedback to fix any bugs or issues before releasing the app to the public.

These examples illustrate how beta-test agreements work and how they can help software developers improve their products before releasing them to the public.
