Alpha Testing vs Beta Testing

Alpha and Beta testing are critical for any software product. Most of the software issues have been found in Alpha and Beta testing.  Generally, software professionals got confused about these Alpha and Beta terms. In this article, we cover alpha and beta testing separately and then see what the differences between them are.

What is Alpha Testing?

  • Alpha testing is the first phase of testing where the developer and quality team tests the software product against the requirements given by the client.
  • Alpha Testing freezes the requirements and does not allow any new addition of a feature after the completion of testing.
  • Alpha testing started just after the completion of the development of the software.
  • Includes both black and white box methodology to find bugs/issues in the software product.
  • Conducted by the employees within the organization.
  • Generally, the product-developing organization uses quality management tools for tracking bugs/issues.
  • Generally, Alpha testing duration is 4-8 weeks depending on the complexity of the software.

What is Beta Testing?

  • Beta testing is considered the second phase of testing, where real users test the software in a real environment.
  • Beta Testing considers external user acceptance testing.
  • After beta testing, the product is released to limited end users as a beta version for a limited time. Windows 10 also released its beta version for the suggestion of end-users.
  • End users give feedback based on their experience of usage of the software.
  • Generally, the company gathers all feedback from end-users and improved the software based on feedback and user experience in the future release.
  • Beta testing duration is small in comparison with alpha testing. It may range from a few days to a few weeks.
