Acceptance testing is a method of software testing in which the acceptability of a system is tested. The main purpose of this test is to determine whether the system complies with the business requirements and whether it is suitable for delivery.

Types of Acceptance Testing:

1. User Acceptance Testing (UAT): User acceptance testing is done to see if the product is working properly for the user. Specific requirements that are frequently used by customers are primarily picked for testing purposes. This is also termed as End-User Testing.
2. Business Acceptance Testing (BAT): BAT is used to analyze whether or not a product meets the business goals and purposes. BAT focuses primarily on company profits, which are difficult to achieve owing to changing market conditions and new technology, therefore the existing implementation may need to be updated, resulting in extra budgets.
3. Contract Acceptance Testing (CAT): CAT is an agreement that specifies that once the product goes live, inside a predetermined period, the reputation takes a look at what needs to be achieved and it needs to skip all the popularity use instances. A contract known as a Service Level Agreement (SLA) comprises provisions under which payment will be granted only if the Product services meet all of the requirements, indicating that the contract has been met.

This contract may be signed before the product is released. There should be a well-defined contract in terms of the testing period, areas of testing, conditions on difficulties that arise later in the process, payments, etc.

1. Regulations Acceptance Testing (RAT): RAT is used to assess whether a product violates the government’s rules and regulations in the country where it is being released. This may be inadvertent, but it will have a bad influence on the company.

In general, any product or application that is to be published on the market must comply with RAT, as each country or region has its own set of rules and regulations established by its regulatory organizations. If any countries or region’s rules and regulations are broken, the product will not be released in that country or location. Only the product’s vendors will be held directly liable if the product is released despite the breach.

1. Operational Acceptance Testing (OAT): OAT is a non-functional testing method for determining a product’s operational readiness. It mainly includes testing of recovery, compatibility, maintainability, reliability, etc. OAT assures the stability of the product before it is released into production.
2. Alpha Testing: Alpha testing is used to determine the product in the development testing environment by a specialized tester’s team usually called alpha testers.
3. Beta Testing: Beta testing is a method of evaluating a product by exposing it to real end-users, known as beta testers, in their environment. Feedback is collected from the users and the defects are fixed. Also, this helps in enhancing the product to give a rich user experience.

Use of Acceptance Testing:

• To find the defects missed during the functional testing phase.
• How well the product is developed.
• A product is what the buyers genuinely require.
• Customer feedback helps in the enhancement of product performance and user experience.
• Minimize or eliminate any production-related concerns.
