What is the Difference between UAT, Alpha Testing, or Beta Testing?

User Acceptance Testing (UAT).

A person asking for a feature in software should be able to test it to make sure that they are satisfied with the result.

  • As a (user),
  • I want (a feature).
  • So I can (reason for need/business benefit).

Why is UAT necessary?

UAT is the final step in validating the User Story. It meets the expectations of the Product Owner.

When does UAT happen?

UAT is continuous. Sprints may be delivered bi-weekly in some environments. This allows the Product Owner and Development Team to receive continuous feedback.

Who are the UAT participants?

  • Product Owner
  • Members of the Development Team who worked on User Story
  • The Product Owner can invite other stakeholders (Finance Marketing Support) to help with highly specialized features.

What is UAT?

Acceptance Criteria are established when User Stories have been created. Over time, Acceptance Criteria can change. The User Story’s ultimate goal must be achieved.

Why is Alpha Testing necessary?

Alpha Testing is a way to ensure that the software behaves in a wider range of environments and users. Alpha Testing will identify any issues that could prevent Beta Testing.

When does Alpha Testing happen?

Alpha is created after all features have been developed and tested by the Development/QA teams.

  • Weeks of Alpha 1–2
  • 2–3 weeks of development

Who takes part in Alpha Testing?

  • Testers: These are usually internal members of the company, but not part of the Project Team.
  • Supporters: Development, Quality Assurance, and UI/UX Product Owners. These teams support users and analyze feedback in real-time and then document the results.

What is Alpha Testing?

The plan includes:

  • Who tests?
  • Who supports?
  • They’ll be testing all features (test cases)
  • When will they be tested?
  • How to manage issues (reporting and logging, classification, prioritization).
  • Exit criteria (all cases tested, no “show-stopper” defects).
  • Defects can be logged and analyzed in real-time.
  • While some defects can be corrected immediately, others require deeper analysis and may result in the need to develop, integrate, and test more extensively.
  • Some of the defects will be fixed in the future; others could be a trigger for a “no-go” decision.

Beta Testing

After a software release passes Alpha Testing, it should then be made available to the public outside the company. This is where customers can give feedback on their satisfaction with the software’s user interface, features, and overall experience.

Why is Beta Testing necessary?

Beta offers feedback from customers in real customer environments.

When does Beta Testing happen?

Beta is after Alpha Testing, and before the Release Candidate build.

  • Beta weeks 1–2
  • 2–3 weeks of development

Who is eligible to participate in Beta Testing?

  • Beta testers: These are usually actual customers (from the target markets) who have been given the software free of charge or as an incentive.
  • Supporters: Development, Quality Assurance, and UI/UX Product Owners. These teams support users and analyze feedback in real-time and then document the results.

What is Beta Testing?

A plan that includes:

  • Who tests?
  • Who supports?
  • They’ll be testing all features (test cases)
  • When will they be tested?
  • How to manage issues (reporting and logging, classification, prioritization).
  • Exit criteria (all cases tested, no “show-stopper” defects).
  • Defects can be logged and analyzed in real-time.
  • While some defects can be corrected immediately, others require deeper analysis and may result in the need to develop, integrate, and test more extensively.
  • Some of the defects will be fixed in the future; others could be a trigger for a “no-go” decision.
