Acceptance Testing Definition, Types, and Examples

Gain hands-on experience, enhance your skills, and unlock exciting career opportunities. The purpose of UAT is to catch any issues or defects before the software is released, reducing the risk of costly bugs and rework later on. Also, it’s essential to use the best testing tools for better and more agile results during the entire testing phase. After completing all the preceding steps, the testing team confirms that the software is free of defects or bugs and is ready to be delivered to the client.

Contract testing ensures that the specifications of a product have been met by suppliers, vendors, or manufacturers who have signed on as contractors to the production process. If something does not live up to the obligations spelled out in the contract, it must be rectified or legal action can be pursued. In addition, you can even apply automation to various types of software testing, improving the overall efficiency and effectiveness of the testing process.
Those sets of prerequisites and conditions are termed acceptance criteria. They are the set of accepted conditions or features required in the developed software application to get accepted by end-users. Suppose a software application requires adding new functionality to generate random numbers. Before the application is released to the market, an acceptance test will be performed. Here, the application’s end-user will test the features in a controlled testing environment.
If the quantity of non-passing test cases does not breach the project’s predetermined threshold, the test suite is said to pass. If it does, the system may either be rejected or accepted on conditions previously agreed between the sponsor and the manufacturer. Developers and testers conduct system testing, while stakeholders, clients, and testers handle user acceptance testing.

Acceptance tests that are unduly focused on technical implementation also run the risk of failing due to minor or cosmetic changes which in reality do not have any impact on the product’s behavior. For example, if an acceptance test references the label for a text field and that label changes, the acceptance test fails even though the actual functioning of the product is not impacted.

Additionally, the sprint would get an additional phase dedicated to the UAT, where the business users handle their validations. Alpha testing is used in the development testing environment by a specialized testers’ team known as alpha testers to determine the product. The feedback and suggestions provided by the alpha testers help improve product usage and fix certain bugs. OAT is non-functional testing used to determine a product’s operational readiness.

  • Whenever possible, the testing occurs in a «war room» or conference room sort where all participants assemble for a day (or several) and work through the list of acceptance test cases.
  • User acceptance test governance ensures the procedure has excellent gates and well-defined Entry and Exit criteria.
  • To address the criteria mentioned above, there are certain software testing tools through which they can run acceptance tests.
  • It also makes sure the quality and design of the product meet both contractual and regulatory obligations in terms of functionality, usability, durability, and safety.
  • Alpha testing’s primary purpose is to evaluate the software’s overall performance, functionality, and usability in a controlled environment.
  • Learn the importance of acceptance testing and how it helps ensure your software application meets the desired specifications.

It is a black-box testing process where the functionality is verified to ensure the software product meets the acceptance criteria. Acceptance testing is a software testing approach where the system is tested for acceptability. It’s the last phase of the software testing process, and it’s important before making the software available for actual use. With multiple tests performed throughout the process, you must ensure that the final product is up to specifications and quality before being put into production. User acceptance testing is the final testing stage in software development before production. It’s used to get feedback from users who test the software and its user interface (UI).

Acceptance Testing Definition, Types, and Examples

Alpha testing is performed by the alpha tester, where the software applications are tested in their development or test environment. Based on the feedback and suggestion by the alpha testers, the application is enhanced for its usage by fixing specific bugs. Alpha testing’s primary purpose is to evaluate the software’s overall performance, functionality, and usability in a controlled environment. Performing tests in the Software Development Life Cycle (SDLC) is crucial to verify the software application for any bugs and quality. Throughout the SDLC process, multiple tests are performed to ensure the application meets the Software Requirement Specifications (SRS) before its release. Among those tests, is performed at the end of the Software Development Life Cycle after system testing.

These may involve chemical tests, physical tests, or performance tests, which may be refined and iterated if needed. If the actual results match the expected results for each test case, the product will pass and be considered adequate. If it is rejected, it may be fixed or abandoned entirely if the required fixes will prove too expensive or time-consuming. Generally, user acceptance testing is conducted after performing various important testing types, such as performance, security, usability, regression, and integration testing.

Contract Acceptance Testing is performed in the software application to test it against the pre-defined and agreed-upon criteria in a contract. Here, the contract means that when the software application is ready for release, the acceptance tests should be conducted within a specific time and address all acceptance use cases. UAT is considered the last phase of the software testing process, conducted after the functional, system, and regression tests are complete. It’s the final test run before the product goes live or before the client accepts delivery. Consider the UAT to be the bow sitting atop the testing package; it’s not conducted until all other testing is done. The testers are familiar with the software’s business requirements, so they can adequately gauge the product’s readiness.
If you want to learn about each testing type in detail, read our detailed guide on software testing types. The user acceptance test is a critical step in the software development process where end-users or stakeholders test the software to make sure it meets their needs and requirements or acceptance criteria. You can use acceptance tests to determine whether a fully developed application is ready for delivery. The testing technique ensures that the business requirements are met, but you should also know the drawbacks. The UAT process is critical, and the testing is performed from the user’s perspective and their point of view. End-users might be asked to check and test the product to achieve the desired results.

If the results match the acceptance criteria for each test case, the test will pass. Acceptance tests are performed based on the SRS to ensure that the developed software application functions as per user expectations. The acceptance criteria function as the checklist which verifies the application and ensures its functions as intended without any bugs.

With this, you can verify whether the developed software application is ready for acceptance by the end user. Operational Acceptance Testing (OAT), part of non-functional testing, is performed to verify and check the operational readiness of the software application before it gets released in the market. In other words, OAT is performed to verify that the application meets the operational requirements, user expectations, and performance standards. User acceptance test helps ensure that the software is user-friendly, works correctly, and meets business requirements. To perform the software testing process rapidly, automated acceptance tests are created and executed to reduce human errors and meet deadlines.

Hence, BAT should not be outweighed in the development process of software applications. The application will go live on passing the test, and beta testers will test those on real devices. If the feedback gives quality assurance to the application, it will then be available to all the software application users. Acceptance testing is a formal process that assesses whether a system meets user needs, requirements, and business processes, enabling users and customers to determine system acceptance. It does not focus on cosmetic errors, spelling mistakes or system testing. User Acceptance Testing is carried out in a separate testing environment with production-like data setup.
acceptance testing
A service level agreement (SLA) specifies that payment will be made only if the products or services meet all requirements, indicating that the contract has been fulfilled. BAT is focused on ensuring whether the software meets the business goals and purposes. In the case of UAT, for example, during actual usage, when the end-user discovers the bugs, the project suddenly slows down, costs rise, and timeframes for the end customer are impacted. In contract acceptance testing, the software under development is tested according to the specifications and criteria agreed upon in a predefined contract. In general, user acceptance testing refers to testing among simulated and real users. But there are other facets of UAT that play a role in this phase of development as well.
