Chapter 2 – Testing Throughout the SDLC
Alpha Testing – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
Simulated or actual operational testing by potential users, customers or an independent test team at the developer’s site, but outside the development organization.
In simple words
Early real-world testing done on the developer’s premises, usually by a separate QA team or invited customers, before shipping.
Exam tip
Alpha happens at the developer’s site; beta happens at the customer’s site — the location and audience are the exam giveaway.
