What is User Acceptance Testing (UAT)?
- User acceptance testing (UAT) is done by end users.
- User Acceptance Testing (UAT) is end-to-end testing where real-time scenarios are implemented while testing the application.
- Acceptance testing is also known as User acceptance testing (UAT).
- Generally, User acceptance testing (UAT) is done by the customer and checks whether the application is working according to given business scenarios or real-time scenarios.
- User acceptance testing (UAT) is done before production/live.
- User acceptance testing (UAT) is the process of collecting feedback from customers.
- Test team, Development team, and customer involved in User acceptance testing (UAT).
- User acceptance testing (UAT) starts after completing system and function testing i.e. SIT.
- The customer decides which user story needs to be executed.
- Customers decide whether the build should go to production or not after User acceptance testing (UAT).
Types of User Acceptance Testing (UAT)
- Alpha Testing or Internal Acceptance Testing
- Beta Testing or External Acceptance Testing
1. Alpha Testing or Internal Acceptance Testing
- Alpha testing is the final stage of testing performed by your QA team to check that your application is ready for release outside your company.
- The testing is coordinated in-house, and structured and is usually done by your own test team.
- Alpha testing happens for web base applications.
- Alpha testing can be done in front of testers, developers, and customers.
- Real customers mostly in the service-based industries involved in alpha testing like HDFC, IDBI, etc.
- The aim is to test every single user flow end to end. The idea is to ensure that your software is bug-free, stable, and functioning as expected.
2. Beta Testing or External Acceptance Testing
- Beta testing involves releasing the software to a limited number of real users. They are free to use it as they want.
- However, the users give feedback about how the application performs.
- It is done to get feedback from real users based on their experience.
- Many product-based software companies use beta testing to find out if a new feature/improvement for any software product.
- The developer and tester were less involved in it.
- Customers like Microsoft, Rupay, master card, etc.
- In beta testing when the developer and the tester complete their work then the same product sometimes send to different testers to collect feedback.
Difference between Alpha Testing and Beta Testing
|Alpha testing is performed by testers who are usually internal employees of the organization.||Beta testing is performed by the end users or from a different team QA member.|
|Alpha testing is performed at the developer’s site.||Beta testing is performed by the end-user of the product.|
|Alpha Testing is done normally in a service-based organization.
|Beta Testing is normally done in a product-based organization.|
|Developers can immediately address critical issues or fixes in alpha testing.||Most of the issues or feedback or improvements collected from the beta testing will be implemented in future versions of the product.|
Use or Advantage of User Acceptance Testing (UAT)
- To find the defects missed during the functional testing phase.
- How well the product is developed.
- A product is what actually the customers need.
- The client satisfies after the user acceptance testing (UAT).
- Feedback helps in improving product performance and user experience.
- Minimize or eliminate the issues arising from production.
Q 1. Can system testing be done at any stage?
Answer: No, we cannot do system testing at any stage, it must start only if all modules work correctly and are in place, but it should be performed before UAT (user acceptance testing).
Q 2. Distinguish between System Testing and UAT.
Answer: UAT: User Acceptance Testing (UAT) is a process of determining whether the product will meet the needs of its users or not. Done by the client to ensure all requirements are fulfilled.
System Testing: Also known as end-to-end testing, Here testing is done as a whole software/project and finding defects when the system is under test.
Q 3. Exit criteria for UAT or When we can stop UAT?
Before moving into production, the following needs to be considered:
- No critical defects open
- Business requirements met
- UAT Sign off meeting with all stakeholders/clients and they
