What distinguishes alpha testing from beta testing?

Alpha testing is primarily characterized by being conducted internally within the organization and is typically performed before any external user involvement. This stage allows developers to identify and fix issues before the product is released to a limited group of users for beta testing. During alpha testing, the primary objective is to ensure that the software is working as intended and to make necessary adjustments based on early feedback from internal team members.

In contrast, beta testing occurs after alpha testing and incorporates a broader audience, usually involving actual users who test the software in a real-world environment. This allows for additional feedback from users who have different perspectives and experiences compared to those of the internal team.

Focusing solely on internal testing for alpha distinguishes it from beta testing, which is inherently about external user involvement and feedback collection. Therefore, stating that alpha testing is done before any user involvement accurately captures its role in the software development lifecycle.
