User Acceptance Testing (UAT)

User Acceptance Testing (UAT) is a crucial phase in software testing where the software is tested in a real-world scenario by end-users to ensure it meets their requirements and functions as expected. Unlike other forms of testing, UAT focuses on validating the software’s user-friendliness, functionality, and performance from the user’s perspective.

User Acceptance Testing (UAT) serves the purpose of ensuring that the software meets the business requirements and is ready for deployment by validating its functionality in a real-world environment. It allows end-users to test the software to ensure it meets their needs and operates as expected, helping to identify and fix any issues before the final release. UAT is crucial for quality assurance and customer satisfaction, as it ensures that the software is user-friendly, reliable, and meets all specified criteria.

Purpose of UAT

The purpose of User Acceptance Testing (UAT) is to identify bugs in software, systems, and networks that may cause problems for users. UAT ensures that software can handle real-world tasks and perform to development specifications. Users are allowed to interact with the software before its official release to see if any features were overlooked or if any bugs exist.

Basic guidelines of UAT: When testing messages using multiple people instead of separate devices test one sender at an independent location without having been online with each other since late last year when sending information over short distances but still communicating back home by telephone, and When transmitting through email addresses rather than social media accounts where you are talking publicly about your service before delivering it via messenger services like Signal. 

Who performs UAT?

User Acceptance Testing (UAT) is typically performed by end-users or clients who will ultimately use the software in their daily operations. These individuals represent the target audience for the software and are responsible for validating whether the software meets their requirements and expectations before it is deployed.

Types of User Acceptance Testing

Below are the 5 types of user acceptance testing:

1. Beta User Acceptance Testing

• Beta UAT means that users who have completed one or more rounds of tests will be shown a popup stating if they are accepted for testing by the new version of Angular2 (a beta release). 
• The application is tested in a natural environment.
• It reduces risks, and failures, and improves the quality of the product through customer feedback.

2. Black Box Testing

• In black box testing, end-users or testers evaluate specific functionalities of the software without knowing the internal workings or code structure.
• Testers focus on how well the software performs its intended tasks from a user perspective, checking inputs and outputs against expected outcomes.
• This type of testing ensures that the software meets user requirements without requiring knowledge of its underlying technical details.

3. Operational Acceptance Testing (OAT)

• Operational Acceptance Testing (OAT) is a software testing technique that evaluates a software application’s operational readiness before release or production. 
• The goal of operational acceptance testing is to ensure system and component compliance as well as the smooth operation of the system in its Standard Operating Environment (SOE). 
• OAT Testing (Operational Acceptance Testing) is also known as Operational Readiness Testing (ORT) or Operational Testing. 
• These test cases guarantee there are work processes set up to permit the product or framework to be utilized. 
• This ought to incorporate work processes for reinforcement plans, client preparation, and different support cycles and security checks.

4. Contract Acceptance Testing

• Contract Acceptance Testing refers to the process of testing developed software against predefined and agreed-upon criteria and specifications. 
• When the project team agrees on the contract, they define the relevant criteria and specifications for acceptance.
• Contract acceptance testing involves testing the software against specific criteria and specifications outlined in the project contract or agreement.
• This type of UAT ensures that the delivered software aligns with the agreed-upon terms and conditions between the client and the development team.

5. Regulation Acceptance Testing

• Regulation AT is generally called Compliance AT.
• This sort of affirmation testing is done to guarantee the thing dismisses no rules and rules that are set by the regulating associations of the particular country where the thing is being conveyed. 
• Generally, things that are available from one side of the planet to the other should go through this testing type considering the way that different countries have different standards and rules set by discrete directing associations.

6. Alpha User Acceptance Testing

• Alpha UAT means that your user is tested before they get a hold of the product, so if you’re testing users’ usage patterns, we recommend running an alpha test to ensure it can pass all acceptance tests before the beta gets deployed into production. 
• It enables more rapid validation in early adopters/testers which allows fast adjustments as the software progresses through development with each release cycle toward feature maturity.
• It ensures that there is no opportunity for bugs or exploits once security updates become available based upon adoption levels achieved by products launched later during their life cycle such should be done at least six months after launch.
