Alpha Testing vs Beta Testing: Exploring Differences

In the software development process, different types of testing need to be performed to check software application functionality and usability. Among those, two very important tests are the alpha and beta tests.

Comparing alpha testing vs beta testing, alpha testing is carried out right after software development, wherein the software undergoes internal checks using black and white-box testing techniques to unearth potential bugs.

On the other hand, beta testing involves testing the software with a larger group of users, typically outside the organization that developed it. Both tests are essential to execute during the Software Testing Life Cycle (STLC). However, they hold specific differences.

This blog on alpha testing vs beta testing highlights the key differences between alpha and beta testing. Plus, it discusses its key features, strategies, and other aspects.

What is Alpha Testing?

Alpha testing is part of acceptance testing that involves testing software applications during the Software Development Life Cycle (SDLC). This test is run by the internal employees of the organization who are aware of the software applications and their functionality.

It is generally the final stage of software testing, where the software application is tested end-to-end before being handled for beta testing by users outside the organization. Such verifications use black-and-white-box testing strategies in a dedicated testing environment to simulate real user behavior.

Feedback gathered during alpha testing is invaluable for developers and testers, as it helps them understand how users interact with the software and identify areas for improvement. By addressing issues discovered during alpha testing, developers can enhance the overall quality and reliability of the software before it is released to a wider audience.

Importance of Alpha Testing

In this section of the blog on alpha testing vs beta testing, we will list several reasons why it is important to perform alpha testing.

Alpha testing is a crucial step in the software development process that shouldn’t be skipped. Here’s why it’s important:

• It allows you to assess if the core functionalities of the product are working as intended. Performing this test helps refine the product and ensure it meets the needs of the target audience.
• It helps identify and fix major bugs and usability issues before the product reaches beta testers or the general public. This will ensure a more polished and functional final release.
• It reduces the risk of encountering major issues during beta testing or after launch by fixing issues early on. This can save time and resources and prevent potential damage to the product’s reputation.
• It takes place in a controlled environment, allowing testers to focus on specific functionalities and recreate scenarios to identify problems more efficiently.
• It provides valuable feedback from a fresh perspective (internal testers) on the product’s usability and overall user experience. Such feedback can lead to significant improvements before a wider release.

When Should You Perform Alpha Testing?

The ideal time to perform alpha testing is right before the software transitions from internal development to a wider audience.

• The development team has completed the initial coding and built the foundational features. Alpha testing allows for a first look at the overall functionality before further refinement.
• The core functionalities that define the software’s purpose should be built and functional. Alpha testing helps validate these functionalities and ensure they work as intended.
• A controlled testing environment, separate from the final user environment, should be established. This allows testers to focus on specific functionalities and recreate scenarios for efficient issue identification.
• A dedicated group of internal testers, like developers or testers, should be available to provide feedback during alpha testing.

Who Performs Alpha Testing?

Alpha testing is usually performed by internal employees of the organizations, usually testers or sometimes developers. To ensure a diverse range of perspectives, the testing team comprises several other teams within the organization.

Test cases are distributed among testers to incorporate various usage scenarios and speed up the testing process. Testers record issues in a bug-tracking tool or convey them directly to the development team. Alpha testing continues until serious bugs are resolved, where the product reaches a “feature lock” stage where no new functionality is added.

Phases of Alpha Testing

In this section of the blog on alpha testing vs beta testing let’s look at different phases to run alpha tests.

Alpha testing is executed in two different stages:

• Stage 1: In stage 1 of the alpha testing, the skilled software developers perform white-box testing and check the software application at a granular level to ensure its reliability. At this phase, decision coverage, statement coverage, branch coverage, and other code-level aspects are evaluated.

The testers in this phase use debuggers for easy bug detection. During alpha testing, testers often uncover numerous errors, bugs, crashes, missing features, and documentation issues.

• Stage 2: The stage 2 of alpha testing involves handing over the software to testers for further testing in an environment resembling the production setup. Here, the main focus is black-box testing by non-technical individuals, covering specific use case testing, cause-effect testing, and decision table testing.

Entry and Exit Criteria of Alpha Testing

Alpha testing is an internal testing phase conducted before a software application is released to a broader audience. Here’s a breakdown of the typical entry and exit criteria for this stage.

Entry criteria: It establishes the prerequisites for starting testing. The following criteria are outlined for alpha testing:

• All functionalities of the software application are implemented and ready for testing.
• A build is ready for test execution.
• The test environment is correctly configured.
• The testing team possesses adequate knowledge of the software application.
• All features are tested on the targeted platforms.
• No critical bugs exist in the software application.

Exit Criteria: It describes the conditions necessary to conclude testing. The following are the exit criteria for alpha testing:

• Exclusion of any additional features.
• Compilation of a report detailing any significant bugs.
• Delivery of the test summary report.
• Communication of bug-fixing issues to the developers.
• Resolution and closure of critical issues.

How to Perform Alpha Testing?

In this section of the blog on alpha testing vs beta testing, let’s look at how to perform alpha testing.

Alpha testing involves different steps, which are as follows:

1. Review Requirements: The tester first evaluates the functional requirements and system specification design.
2. Create Test Cases: Based on the requirement review output, they create test cases and a test plan during this phase.
3. Run Test Cases: When the test case and test plan are created, they are implemented.
4. Record Defects: They document any identified bugs found in the software application.
5. Fix Bugs: Once all bugs are identified and logged, they address them.
6. Retesting: After the developer resolves all issues, retesting is done to check that no issue or bug is left.

Challenges of Alpha Testing

Even though alpha testing is a crucial part of the software development process, you might encounter certain challenges while performing it. Here are some of those:

• Alpha testing is only performed by the internal QAs who are well aware of the software codebase. This could limit the diversity of perspectives and skill sets, potentially overlooking specific issues that users with different backgrounds might encounter.
• It may cause discrepancies between the tester’s and user’s perspectives on the test data, leading to software functionality differences.
• It has limited test scope and thus fails to consider all the critical issues in the software application.
• It cannot fully replicate all aspects of the real environment.
• It is very time-consuming, especially for software with complex workflows, as it demands thorough testing across every aspect of the application.

In the next section of this blog on alpha testing vs beta testing, let’s explore some best practices for performing alpha testing.

Best Practices of Alpha Testing

Here are some of the best practices of alpha testing that should be used while performing it to optimize the test process:

• Ensure that alpha tests are formulated based on the agreed functional requirements and design specifications.
• Review these tests for functional specs and test cases to provide context and direction, and develop a test plan accordingly beforehand.
• Perform the tests and log any detected defects in detail using a requirement traceability matrix.
• Document all identified bugs and usability issues, regardless of immediate resolution, for potential future consideration.
• Avoid delaying issue fixes until beta testing.
• Verify its resolution through retesting.
• Evaluate the product’s usability within real-world workflows.
• Collect feedback from all participants to inform future improvements and reviews.

Once alpha testing is completed, the software application undergoes beta testing for real-user feedback. In the next section of this blog on alpha testing vs beta testing, we will discuss beta testing in detail.

What is Beta Testing?

Beta testing is the process of testing the developed software application for its functionality by a small group of real users. The application is tested in a real-world environment just before its release in the market. In simple terms, it is the final test of the beta version of the software application to find any undetected bugs or errors.

Here, the real users test out the software application and give feedback to the developers. They get details on the features of the application and report usability issues. Based on the feedback, developers optimize the functioning and performance of the software applications. Hence, beta testing allows developers to detect the bug early and ensure a seamless user experience.

Importance of Beta Testing

Beta testing is one of the important software testing types that should not be skipped for the following reasons:

• It adds another layer of validation beyond internal testing, helping to catch issues that might have slipped through the cracks.
• It allows real-world users to interact with software in unforeseen ways, uncovering bugs or usability problems the QA team might have missed.
• It provides a more comprehensive range of perspectives and test scenarios by representing a broader user base than the internal QA team.
• It allows potential users to interact with the software early on, fostering a sense of community and gathering valuable feedback.
• It helps prevent negative reviews and potential reputational damage by identifying and fixing issues before a public release.
• It can be more cost-effective, as a small group of users test the software who are not internal employees.

When Should You Perform Beta Testing?

In this section of the blog on alpha testing vs beta testing, let’s look at when you should run the beta tests.

Beta testing is usually performed after alpha testing. There are various scenarios that call for beta testing; here are five common ones below:

• All critical bugs identified during alpha testing have been addressed and verified as fixed.
• The software is functionally stable and reliable.
• The software’s core functionalities are refined and user-friendly based on alpha testing feedback.
• Clear objectives are established for the beta test, such as gathering user feedback on specific features or evaluating performance under real-world conditions.
• A well-defined group of beta testers is identified, representing the target audience for the software.

Who Performs Beta Testing?

As already discussed in the previous section, beta testing is performed by real users or intended audiences who are not directly associated with software development. They are called beta testers. They may include the following:

• External Users: These are ideal candidates as they represent the actual target audience for the software. They can provide valuable feedback on real-world usability and identify issues internal testers might miss.
• Volunteers: Folks who are eager to try out new software and contribute to its development. They may be motivated by early access, a sense of community, or the chance to influence the product.
• Users: A broader term encompassing both external users and volunteers. It can refer to anyone participating in the beta test who is not directly involved in the software development.
• Professional Testers: Experienced individuals skilled in testing methodologies. They can provide a structured, thorough software evaluation, identifying bugs and usability issues.

Entry and Exit Criteria of Beta Testing

Beta testing is conducted after the software has been tested by the internal employees or after alpha testing has been done. Here’s a breakdown of the typical entry and exit criteria for this stage.

Entry Criteria:

• A formal sign-off that confirms critical bugs from alpha testing have been fixed.
• A stable software application that includes all functionalities intended for testing.
• A well-configured testing environment that closely mirrors the intended production environment.
• A bug-tracking tool that easily reports issues to developers to track and address them efficiently.

Exit Criteria:

• Resolution of all critical and high-priority issues identified during beta testing. Minor issues can be documented for future consideration.
• A test report to summarize the beta testing process, key findings (including bugs and user feedback), and recommendations for improvement.
• Notify developers of all raised issues and keep them informed about critical and high-priority issues that require immediate attention.

How to Perform Beta Testing?

In this section of the blog on beta testing vs alpha testing, let’s look at how to run the beta tests.

Beta testing is easy to execute, and you need to follow just a few simple steps:

1. Plan: In this stage of beta testing, the team determines the number of participants, the type of beta testing to be used (open or closed), and the duration of the test. Here, testing parameters are established in advance to ensure adherence during the testing phase and provide clear guidance to testers.
2. Recruit Participants: Once participant numbers and profiles are determined, the next step is recruitment. The recruitment strategy depends on the desired participant profiles. Early invitations are vital to gauge participant numbers and prepare for potential cancellations.
3. Launch Software Application: During the launch of the beta version of software applications, you must ensure the experience of participants with it. The developers also ensure that the download of software applications is easy and error-free through the shared links. They are also checked for compatibility across multiple browsers, devices, and operating systems. In addition, clearly communicating expectations to participants regarding feedback and surveys ensures adequate preparation.
4. Collect and Analyze Feedback: Collecting and analyzing the feedback for the software applications is important. To the collected feedback, the developers promptly respond and demonstrate commitment to user satisfaction and developing positive brand impressions. Analyzing gathered data enables targeted improvements, enhancing the quality assurance process for future software applications.

Challenges of Beta Testing

Some of the challenges of beta testing that should be known are as follows:

• There is no control over the testing and test environment, thus making it challenging for the developers and testers to reproduce bugs because the testing environment varies from user to user.
• There might be numerous duplicate bugs.
• You might receive limited or unclear feedback from users. Some may not provide enough detail, while others just give generic comments.
• A multitude of issues can lead to negative publicity for the software application since the software testers are end-users with no allegiance to the development team.

Best Practices of Beta Testing

Here are some recommended practices to consider when testing beta applications.

• Strike a balance, ensuring the number of users is neither too low nor too high, as this could result in unclear feedback.
• Diversify your pool of testers, ensuring they bring at least one unique perspective.
• Install the third-party applications if the application under test isn’t hosted on an authorized platform.
• Use forms, as they provide a convenient and efficient way to collect feedback from your testers during the beta testing phase. However, it’s worth noting that adding more fields to forms can increase friction for users.

Alpha Testing vs Beta Testing: Core Differences

In the above sections of this blog on alpha testing vs beta testing, we have individually discussed alpha and beta testing. Now, here are the core differences between alpha and beta testing.

Alpha Testing	Beta Testing
Alpha testing is performed by internal employees of the organization.	Beta testing is carried out by end users who are not employees of the organization.
Alpha testing takes place at the tester’s location	Beta testing is performed at a user’s location or by end users of the software application.
It is performed during the final stage of the development process before releasing it to the users.	It is performed after the alpha testing by the real users outside the organization.
In alpha testing, reliability and security testing are not performed extensively.	Reliability, security, and robustness are checked during beta testing.
Alpha testing involves both white-box and black-box techniques.	Beta testing typically uses black-box testing.
Alpha testing may require an extended execution cycle.	Beta testing usually requires only a few weeks of execution.
Critical issues or fixes can be promptly addressed by developers in alpha testing.	Most issues or feedback collected from beta testing will be integrated into future versions of the software applications.
Alpha testing aims to ensure the quality of the software applications before proceeding to beta testing.	Beta testing also focuses on the software application’s quality but gathers user input on them and ensures readiness for real-time users.
Less expensive since it’s carried out internally.	More costly due to external resources and real-world usage involved.

Alpha testing should start only after the software application successfully passes the unit and integration testing phases. The more testers engaged in the alpha test, the greater the likelihood of identifying bugs early enough to address them before they escalate into serious issues.

However, before beta testing, it’s crucial to identify a diverse group of users, including end users and developers, who will be involved in performing beta testing. Avoid limiting this group to just one or two testers.

Both alpha and beta testing types are important and crucial for the quality and reliability of your software application, which involves testing your application across various devices, operating systems, and browsers your audience uses.

While manual testing is one approach to testing your software application, it often proves to be time-consuming. Alternatively, you can use a faster and more scalable solution by leveraging automation testing frameworks and tools. When it comes to automated testing, cloud-based testing solutions offer several benefits.
