What is the term for testing conducted by users at the developer's site?

The term for testing conducted by users at the developer's site is correctly identified as alpha testing. This phase occurs during the software development lifecycle, prior to its release. Typically, alpha testing is performed by a select group of users, often comprising internal team members or stakeholders, who use the software in a controlled environment. The main purpose of alpha testing is to identify bugs before the product is made available to a broader audience. Feedback gathered during this process allows developers to make necessary adjustments and improvements.

In contrast to alpha testing, beta testing occurs after the software has reached a state where it can be used effectively but still has not been officially released to the public. It is conducted at a user’s location rather than the developer’s site, and it involves a larger group of external users who provide insights and identify any issues that might not have been caught in earlier testing phases. Acceptance testing, on the other hand, validates the software against user requirements and is generally performed post-development to ensure it meets the necessary standards before being deployed. Regression testing focuses on verifying that recent code changes have not adversely affected existing functionalities; this type of testing is not specific to user's involvement or location.

Recognizing the specific setting and user involvement in alpha testing clarifies why it is
