Alpha, Beta and Gamma Testing- What is the difference?

What is software testing?

Software Testing is the way of identifying the correctness and quality of software program. The reason for this is to check whether the product fulfills the particular prerequisites, needs and desires for the client. In other words, testing is executing a system or application to find software bugs, defects or errors. The activity of testing is to discover the reasons of application failures so that they can be corrected according to requirements. Types of software testing are- Alpha testing, Beta Testing, Gamma Testing. Let us discuss one by one. 

Alpha, Beta, Gamma Testing

1. Alpha testing-

Alpha testing is a type of acceptance testing. It is performed to discover all possible issues/bugs before releasing the product. The focus of this testing is to simulate real users by using a black box and white box techniques. The aim is to carry out the tasks that a typical user might perform. Alpha testing is an internal testing performed by in-house development or QA team. This kind of testing is called alpha only because it is done early on near the end of the development of the software, and before beta testing. The alpha phase includes the following testing types: smoke, sanity, integration, systems, usability, UI (user interface), acceptance, regression, and functional testing. It is quickly routed to the development team, if an error is detected. Alpha testing helps to identify issues missed at the stage of requirement gathering.

Advantages of Alpha testing-

1. This type of testing provides better view about the reliability of the software at an early stage. It also helps to simulate real time user behavior and environment, and ability to provide early detection of errors with respect to design and functionality.

2. Alpha testing provides better insights about the software’s reliability and robustness at its early stages. You would even be able to detect many of the serious issues quite easily during the alpha test, because other minor design structures are yet to be integrated.

3. This testing ensures that the user will get high quality services in the form of complete functionalities and stability.

4. The most widely recognized  requirement is that the software provided to the user should work appropriately according to the purpose for which it is created. Conducting alpha tests will reveal whether the software has all these necessary features to pass the strict quality standards set by customer

2. Beta Testing- 

Beta testing can be called pre-release testing. It can be conducted  with a limited number of end users called beta testers before the official product delivery. There are two types of beta testing- Open beta and Closed Data.

  • Open beta is for a large group of end users or to everyone interested
  • Closed beta is available only to a limited number of users that are selected especially for beta testing.

During beta testing, end users detect and report bugs they have found. All the testing activities are performed outside the organization that has developed the product. Beta testing helps to identify the gaps between the stage of requirements gathering and also their implementation. The product that has passed beta testing is called beta release.

Advantages of Beta Testing-

1. Opportunity to get your application into the hands of users prior to releasing it to the general public. Beta testers can identify issues with your application that you may have not noticed, such as confusing application flow, and even crashes.

2. Beta testing reduces product failure risk via customer validation.

3. It also improves product quality via customer feedback.

4. Cost effective compared to similar data gathering methods.

5. Creates goodwill with customers and increases customer satisfaction.

Gamma Testing-

One can perform a Gamma Testing when software is ready for release with specified requirements. This testing is performed directly by skipping all the in-house testing activities. The software is almost ready for final release. No feature development or enhancement of the software is undertaken and tightly scoped bug fixes are the only code.

Gamma testing is the third level of testing, performed generally for safety. Tragically, Gamma testing is becoming a thing of the past, killed off by decreased time cycles, competitive pressure, and the myopic focus on quarterly benefits.

Difference between Alpha testing and Gamma testing-

  • Alpha Testing is conducted by a highly skilled testers at development site. Beta Testing is always conducted in Real Time environment by end users at their own site.
  • Since Alpha Testing is done onsite therefore developers as well as business analyst are involved with the testing team whereas in Beta Testing developers and business analysts are not at all involved.
  • Alpha testing requires lab environment or testing environment, whereas Beta testing doesn’t require any lab environment or testing environment.
  • Beta testers can be naive or proficient end users of software product but alpha testers are always high skilled professional testers.
  • Alpha Testing involves both black box testing as well as white box testing. Beta Testing is always a black box testing or functional testing.
  • Before the launch of software product into the market alpha testing is done. Whereas Beta Testing is done at the time of software product marketing.
