What Is Alpha And Beta Testing?

What Is Alpha And Beta Testing?

Alpha Testing and Beta Testing are the standard terms used in software industries, and both have their scope and significance in testing practice. I want to explain this with a simple example as follows. Whenever firms like Microsoft or IBM launch their software product in the market, it undergoes both Alpha and Beta Testing before it is available for the end-user.

Let’s say these reputed firms are launching their new operating system in the market, so before launching an operating system, an organization conducts testing in two phases, known as the Alpha Testing phase and Beta Testings phase.

In the Alpha Testing phase, testing is conducted by a team of highly skilled testers at onsite. In contrast, in the Beta Testings phase, this tested software product is made available to the customers or the end-users to test the actual functionality and give their feedback.

To understand both of these terms in a better way, below are the comparison points.

  • Alpha Testing is a type of testing conducted by a team of highly skilled testers at the development site, whereas customers do beta Testing or end users at their site.
  • For Alpha Testing, there is a dedicated test team; this is not the case with Beta Testing.  Unlike Beta Testing, Alpha Testing is not open for the market or public.
  • Alpha Testing is done for the software application, project, and product, whereas  Beta Testing usually is done for software products like an operating system, write or paint utilities, games, etc.
  • Both alpha and Beta Testing are the kinds of acceptance testing; the only difference is the former is conducted within an organization, whereas the latter conducted out of an organization.
  • Since Alpha Testing is done onsite, therefore, developers, as well as a business analyst, are involved with the testing team. In contrast, in Beta Testing, developers and business analysts are not at all involved.
  • Beta testers can be naive or proficient end users of a software product, but alpha testers are always highly skilled professional testers.
  • Alpha Testing involves both black-box testing as well as white box testing.  Beta Testing is always black box testing or functional testing.
  • Alpha Testing is done before the launch of a software product on the market, whereas Beta Testing is done at the time of software product marketing.
  • Alpha Testing is conducted in the presence of developers and the absence of end-users, whereas for Beta Testing, this is exactly reversed.
  • Since end-users do beta Testing, therefore, it is also known as field testing, but there is no such buy Provigil us online another name for Alpha Testing.
  • Both Alpha Testing and Beta Testing are also known as user acceptance testing (UAT), and the only difference here is former testing is conducted onsite, but the latter testing is conducted offshore.
  • Alpha Testing may be conducted in virtual environments; however, Beta Testing is always conducted in Real-Time environments with end-users.

Bugs or Feedback Comparison:

  • Every software product that a company launches into the market has its destiny associated with its completeness and usability.
  • Software product completeness can be ensured if it is tested thoroughly from end to end, and this Alpha Testing demands a team of highly skilled professional testers who can ensure the software product is complete and ready to get launched into the market.
  • Therefore Alpha Testing is a very challenging job, and the expectation from an alpha tester is very high.
  • It is always expected from an alpha tester that for any software product, no bug should be identified during Beta Testings by the end-user as it may be a huge reputation loss for an organization or its project team collectively.
  • Sometimes organization puts the money offer or prizes for beta testers if they can identify any valid bug in a software product which Alpha Testing team has missed or which may impact overall software product functionality.
  • This prize offers to create interest in beta testers to do black-box testing.
  • Bug identified during Beta is known as software beta version bugs, which are assigned back to the development team for their fixes. After the bug fix, again, software product enters into alpha and Beta Testing cycle with the new software version number.
  • Also, if beta version bugs for a software product are very critical then it may delay the actual launch date of the software product into the market and in this competitive world if one organization delays in launching its product then it could be an opportunity for another organization to launch the same product which is complete and bug-free alpha and beta tested.
  • This organization may bag a good amount of business and money that its competitor could have done.


This can be concluded that every organization emphasis Alpha Testing as well as Beta Testing for its software product. Alpha Testing should be competitive enough that it should not leave any scope for bug identification in Beta Testing. In the real world, an organization desires Beta Testing as a forum or feedback for its software product from end users before its launch.

I love open-source technologies and am very passionate about software development. I like to share my knowledge with others, especially on technology that's why I have given all the examples as simple as possible to understand for beginners. All the code posted on my blog is developed, compiled, and tested in my development environment.
