Introduction  

This blog will mainly discuss one of the Software Testing types, i.e., acceptance testing. Before jumping on the acceptance testing, let's first understand what testing is,

Software testing is the evaluation procedure and verification of the working of the software product or the application.

Now, talking about acceptance testing, it is the type of testing which is used to verify whether the whole system is working as it is intended to work or not.

Now, let's discuss the acceptance testing in detail.

Acceptance Testing

Acceptance testing is one type of software testing used to check whether the software is working as acceptable or not. The main target of acceptance testing is whether the software is compatible with the business model and is completing all the business requirements. Acceptance testing is the last testing mode of the software that ought to be delivered if passed from the acceptance testing. Acceptance testing is the software testing that is performed after the system testing.

Acceptance testing is conducted as black-box testing. Acceptance testing is the squeezing of all the testing processes done previously on the software or the product.

Need Of Acceptance Testing

The application was tested by the QA team (internal testing team) before acceptance testing. The QA team will test the program, and the developers will create it depending on the requirements papers provided to them. Due to a lack of subject expertise, they may have an understanding of the requirements. Their comprehension probably differs from that of business users. During acceptance testing, business users may ensure that everything meets their expectations.

During acceptance testing, business users (clients) get to see the finished product. Users can test the system to see whether it meets the requirements. Acceptance testing also guarantees that the requirements have been adequately conveyed and executed. Business users can acquire confidence in demonstrating the application to end-users in the market.

Since users from the business side will perform acceptance testing, they will better understand what end-users desire. As a result, feedback/suggestions provided during acceptance testing may be helpful in future versions. In future versions, the development team can avoid making the same mistakes.

Steps to Perform Acceptance Testing

  1. Test case Planning - In this stage, the testing team examines the requirement document to determine the goal of the developed product. The requirement document, Process Flow Diagrams, System Requirements Specification, Business Use Cases, Business Requirements Document, and Project Charter were used to organize the tests.
     
  2. Scoping Of Project - In this step, we set the scope of the project. All business processes do not have to be tested. Some of these can be safely disregarded. Acceptance testing begins only when we know the scope of the project.
     
  3. Test Case Designing - This step includes developing test cases based on test plan papers. Test cases should be written so that they cover the majority of the acceptance testing scenarios.
     
  4. Test Case Execution - Test Case Execution involves running test cases with acceptable input data. The testing team gets input values from the end-user, and then all test cases are conducted by both the tester and the end-user to ensure that the program works properly in the actual scenario.
     
  5. Objective Confirmation - When the execution phase is complete and as many flaws as feasible have been rectified, it is time to declare that the project is bug-free and ready to deliver to the client.

Advantages of Acceptance Testing

  • It keeps ongoing maintenance costs as low as possible.
  • Provide enough options for identifying and repairing broken features and usability concerns.
  • Stakeholders utilize the knowledge acquired during acceptance testing to better understand the target audience's needs.
  • It enhances requirement definition since the customer tests the requirement description based on his demands.
  • Increases the robustness and usefulness of the software
  • Improves end-user satisfaction

Types of Acceptance Testing

There are seven significant types of acceptance testing. Let's discuss all of them in detail, 

 

  1. Operational Acceptance Testing
    Operational acceptance testing is commonly known as OAT. This type of testing is used to understand the operational readiness of the software or the product. OAT is a non-functional type of testing. The main test in this type of testing is for checking the compatibility, recovery, maintainability, reliability, etc. of the application or the product. This type of acceptance testing ensures the product's stable property, which has to be delivered for production.
     
  2. Regulations Acceptance Testing
    Regulations acceptance testing is commonly known as RAT. This type of acceptance testing is required to check the compatibility of the software or the product with all the rules and regulations. It is also known as compliance acceptance testing.
     
  3. Alpha Testing
    Alpha testing is the type of testing that is used to check the product in a special development testing environment. A team of specialized testers does this called alpha testers. It is the first end-to-end testing of the product to check its correctness and the functionality of the product or the software. These alpha testers are the internal employees of the company.
     
  4. Beta Testing
    Beta testing is also used to check the product, but it is performed in real-time by exposing it to real end-users. These real end-users are typically known as beta testers. After receiving feedback from these testers, all the defects and problems are checked and fixed. It is one of the final steps in the lifecycle of the software development cycle.
     
  5. User Acceptance Testing
    User acceptance testing is commonly known as UAT. The end-user or the client performs this type of acceptance testing to verify/check the software system before proceeding to the production environment. It is performed in the final stage of the testing process.
     
  6. Contract Acceptance Testing
    Contract acceptance testing is also commonly known as CAT. This type of testing is a contract which means that a developed software or product is tested against predefined criteria and specifications which are already defined. The whole standards and specifications are agreed upon in the contract.
     
  7. Business Acceptance Testing
    This type of testing is to check the product's compatibility with the business goals and targets. Its primary purpose is to ensure business profits.
     

Uses of Acceptance Testing

  • To identify flaws that were overlooked during the functional testing phase.
  • The degree to which the product has been developed.
  • A product is what the customers require.
  • Feedback/surveys assist in improving product performance and customer experience.
  • Improve the process by using RCAs as input.
  • Reduce or eliminate the problems caused by the Production Product.

FAQs

  1. What is the difference between the syntax layer and the presentation layer?
    The presentation layer is also called the syntax layer. The syntax layer is responsible for managing the syntax of the data properly.
     
  2. List all the layers of the OSI model?
    Application layer
    → Presentation layer
    → Session layer
