Alpha Testing and Beta Testing (A Complete Guide)

Alpha and Beta testing are the Customer Validation methodologies (Acceptance Testing types) that help in building confidence to launch the product, and thereby results in the success of the product in the market.

Even though they both rely on real users and different teams feedback, they are driven by distinct processes, strategies, and goals. These two types of testing together increase the success and lifespan of a product in the market. These phases can be adapted to Consumer, Business, or Enterprise products. 

This article will give you a complete overview of Alpha Testing and Beta Testing in a precise manner.

Alpha Versus Beta Testing

Overview

Alpha and Beta Testing phases mainly focus on discovering the bugs from an already tested product and they give a clear picture of how the product is actually used by the real-time users. They also help in gaining experience with the product before its launch and the valuable feedback’s are effectively implemented to increase the usability of the product.

Goals and methods of Alpha & Beta Testing do switch between themselves based on the process followed in the project and can be tweaked to be in-line with the processes.

Both these testing techniques have saved thousands of dollars to large-scale software releases for companies like Apple, Google, Microsoft etc.

What is Alpha Testing?

This is a form of internal acceptance testing performed mainly by the in-house software QA and testing teams. Alpha testing is the last testing done by the test teams at the development site after the acceptance testing and before releasing the software for beta test.

Alpha testing can also be done by the potential users or customers of the application. But still, this is a form of in-house acceptance testing.

What is Beta Testing?

This is a testing stage followed by the internal full alpha test cycle. This is the final testing phase where the companies release the software to few external user groups outside the company test teams or employees. This initial software version is known as the beta version. Most companies gather user feedback in this release.

In short, beta testing can be defined as– the testing carried out by real users in a real environment.

Though companies do rigorous in-house quality assurance from dedicated test teams, it’s practically impossible to test an application for each and every combination of the test environment. Beta releases make it easier to test the application on thousands of test machines and fix the issues before releasing the application to the public.

The selection of beta test groups can be done based on the company needs. The company can either invite few users to test the preview version of the application or they can release it openly to give it a try by any user. Fixing the issues in the beta release can significantly reduce the development cost as most of the minor glitches get fixed before the final release.

Until now many big companies have successfully used beta versions of their most anticipated applications. E.g. Recently Microsoft corporation released Windows 10 beta and based on the feedback from thousands of users they managed to release a stable OS version. In the past, Apple also released OS X beta in public and fixed many minor issues and improved the OS based on the user feedback.

Alpha Vs Beta Testing

How Alpha and Beta testing are different from each other in various terms:

Alpha TestingBeta Testing
Basic Understanding
First phase of testing in Customer ValidationSecond phase of testing in Customer Validation
Performed at developer's site - testing environment. Hence, the activities can be controlledPerformed in real environment, and hence activities cannot be controlled
Only functionality, usability are tested. Reliability and Security testing are not usually performed in-depthFunctionality, Usability, Reliability, Security testing are all given equal importance to be performed
White box and / or Black box testing techniques are involvedOnly Black box testing techniques are involved
Build released for Alpha Testing is called Alpha ReleaseBuild released for Beta Testing is called Beta Release
System Testing is performed before Alpha TestingAlpha Testing is performed before Beta Testing
Issues / Bugs are logged into the identified tool directly and are fixed by developer at high priorityIssues / Bugs are collected from real users in the form of suggestions / feedbacks and are considered as improvements for future releases.
Helps to identify the different views of product usage as different business streams are involvedHelps to understand the possible success rate of the product based on real user’s feedback / suggestions.
Test Goals
To evaluate the quality of the productTo evaluate customer satisfaction
To ensure Beta readinessTo ensure Release readiness (for Production launch)
Focus on finding bugsFocus on collecting suggestions / feedback and evaluate them effectively
Does the product work?Do customers like the product?
When
Usually after System testing phase or when the product is 70% - 90% completeUsually after Alpha Testing and product is 90% - 95% complete
Features are almost freezed and no scope for major enhancementsFeatures are freezed and no enhancements accepted
Build should be stable for technical userBuild should be stable for real users
Test Duration
Many test cycles conductedOnly 1 or 2 test cycles conducted
Each test cycle lasts for 1 - 2 weeksEach test cycle lasts for 4 - 6 weeks
Duration also depends on the number of issues found and number of new features addedTest cycles may increase based on real user's feedback / suggestion
Stake Holders
Engineers (in-house developers), Quality Assurance Team, and Product Management TeamProduct Management, Quality Management, and User Experience teams
Participants
Technical Experts, Specialized Testers with good domain knowledge (new or who were already part of System Testing phase), Subject Matter ExpertiseEnd users to whom the product is designed
Customers and / or End Users can participate in Alpha Testing in some casesCustomers also usually participate in Beta Testing
Expectations
Acceptable number of bugs that were missed in earlier testing activitiesMajor completed product with very less amount of bugs and crashes
Incomplete features and documentationAlmost completed features and documentation
Entry Criteria
• Alpha Tests designed and reviewed for Business requirements
• Traceability matrix should be achieved for all the between alpha tests and requirements
• Testing team with knowledge about the domain and product
• Environment setup and build for execution
• Tool set up should be ready for bug logging and test management
System testing should be signed-off (ideally)
• Beta Tests like what to test and procedures documented for Product usage
• No need of Traceability matrix
• Identified end users and customer team up
• End user environment setup
• Tool set up should be ready to capture the feedback / suggestions
• Alpha Testing should be signed off
Exit Criteria
• All the alpha tests should be executed and all the cycles should be completed
• Critical / Major issues should be fixed and retested
• Effective review of feedback provided by participants should be completed
• Alpha Test Summary report
• Alpha testing should be signed off
• All the cycles should be completed
• Critical / Major issues should be fixed and retested
• Effective review of feedback provided by participants should be completed
• Beta Test summary report
• Beta Testing should be signed off
Rewards
No specific rewards or prizes for participantsParticipants are rewarded
Pros
• Helps to uncover bugs that were not found during previous testing activities
• Better view of product usage and reliability
• Analyze possible risks during and after launch of the product
• Helps to be prepared for future customer support
• Helps to build customer faith on the product
• Maintenance Cost reduction as the bugs are identified and fixed before Beta / Production launch
• Easy Test Management
• Product testing is not controllable and user may test any available feature in any way - corner areas are well tested in this case
• Helps to uncover bugs that were not found during previous testing activities (including alpha)
• Better view of product usage, reliability, and security
• Analyze the real user's perspective and opinion on the product
• Feedback / suggestions from real users helps in improvising the product in future
• Helps to increase customer satisfaction on the product
Cons
• Not all the functionality of the product is expected to be tested
• Only Business requirements are scoped
• Scope defined may or may not be followed by participants
• Documentation is more and time consuming - required for using bug logging tool (if required), using tool to collect feedback / suggestion, test procedure (installation / uninstallation, user guides)
• Not all the participants assure to give quality testing
• Not all the feedback are effective - time taken to review feedback is high
• Test Management is too difficult
