Alpha Testing

• Internal employees of the organization, such as the development team, QA (Quality Assurance) testers, and other internal stakeholders.
• In a controlled, in-house environment, often at the developer's site or in a dedicated lab.
• It occurs relatively early in the development process, after major features are complete but before the product is released to external users. It serves as a pre-release internal check.
• The primary goal is to find critical bugs, system failures, and major usability issues.
• Alpha testing is the first end-to-end testing of the product, done by the people who built it, to make sure it's functional and stable before it's shown to the public.

Beta Testing

• A select group of real users or potential customers who are not part of the development team.
• In a real-world environment. Testers use the product on their own devices, on their own networks, and in their own day-to-day settings, simulating actual usage conditions.
• It follows a successful alpha test. It's the final stage of testing before the official public release.
• The main objective is to gather feedback on the overall user experience, usability, performance, and reliability in real-world scenarios.
• Beta testing is the "dress rehearsal" for a product launch, where real users provide feedback to help refine the product and ensure it meets market expectations.

Summary Table

Feature: Alpha Testing

• Testers: Internal employees (dev team, QA)
• Environment: Controlled, in-house lab
• Timing: Early in the development process
• Focus: Core functionality, bug identification, stability
• Technique: White-box and black-box testing
• Objective: Ensure the product is functional and stable for beta testing

Feature: Beta Testing

• Testers: External users (potential customers, public)
• Environment: Real-world user environment
• Timing: Late in the development process, just before release
• Focus: Usability, user experience, performance, reliability in real-world use
• Technique: Primarily black-box testing
• Objective: Gather real-world feedback to refine the product for the final release
