What Are The Need Of Alpha Testing And Beta Testing In Software Testing


Alpha Testing

Alpha testing takes place at the developer’s site, before release software to external customers.Developers observe the users and note problems.

It is testing of an application when development is about to complete and minor design changes can still be made as a result of alpha testing.

Alpha testing is final testing before the software is released to the general public.


Alpha Testing has two phases:

  • 1st phase of alpha testing, the software is tested by in-house developers. The goal is to catch bugs quickly.

  • 2nd phase of alpha testing, the software is handed over to the software QA staff, for additional testing in an environment that is similar to the intended use.

Beta Testing

Beta Testing is also known as field testing. It takes place at the end user’s site by the end users to validate the usability, functionality, compatibility, and reliability testing. It can be considered “pre-release testing.”

Beta testing is also sometimes referred to as user acceptance testing (UAT) or End user testing.

Beta Testing has two type:

  • Open Beta Testing: – This type is from a larger group to the general public and anyone interested, and report any bugs that they find, and also suggest additional features for a final version.

  • Close Beta Testing: – This type of testing is released to a select group of people for a user test and are invitation only.


Difference Between Alpha and Beta Testing


Alpha Testing

Beta Testing

It is always performed by the developers at the software development site.

It is always performed by the customers at their own site.

It is also performed by Independent Testing Team.

It is not performed by Independent Testing Team.

It is always performed in Virtual Environment.

It is performed in Real-Time Environment.

It is involving both the white box and black box techniques.

It is typically used as black box testing.

It is to ensure the quality of the product before moving to Beta testing.

It also concentrates on quality of the product, but gathers users input on the product and ensures that the product is ready for real time users.

It is not open to the market and public.

It is always open to the market and public.

Reliability and security testing are not performed in-depth.

Reliability, Security, Robustness are checked.
