Not providing the testers with sufficient production data can render the acceptance testing unrealistic. An effective acceptance testing process includes the following 5 major steps. There is a number of acceptance testing types differing by their function and methods of application. With acceptance testing, it is easier to find out if there are any bugs in the software before releasing it. It also saves time and money when fixing errors in production. The testing process is for the satisfaction of the user and the business itself too.
However, if the end-user feels that it is not the case, the end-user will not accept it. Thus, the project team will have to go back to the development definition of acceptance testing phase and get the requirements right. Your team might be developing new software for the company’s human resource department or the finance team.
Acceptance tests are also used as regression tests prior to a production release. A user story is not considered complete until it has passed its acceptance tests. This means that new acceptance tests must be created for each iteration or the development team will report zero progress. Now that you know what user acceptance testing is and why is it so important for any software or any website, it is time to learn about the criteria to perform this test in the first place.
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. It will then either be rejected or accepted by the customer. If it is rejected, it may be fixed or abandoned entirely if the required fixes will prove too expensive or time-consuming. 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.
An acceptance test is a form of software testing, performed by the customer or end-user. It is typically the final stage of software evaluation, only conducted once the development team is confident that any bugs or errors have been resolved. It acts as ‘go’ or ‘no go’ from customers — stopping any substandard software from being launched. Acceptance testing is usually performed by business customers, end-users, or testers from the company. An exception is the alpha type of acceptance testing where internal staff is asked to perform tests and provide feedback. They can be members of the client-facing departments in the organization.
- For example, functional testing only tests a specific function of the application.
- Running those acceptance tests also ensures that no requirement change has happened in the meantime and that everything is as it should be to satisfy the customer.
- The best way to avoid this is to ensure that there’s a good working relationship with the business team (and all the teams, for that matter!).
- The primary goals of the BAT are to reduce major reworks and cut project costs.
- So, your end-user should be your first choice when looking for someone to test your software product.
Once the tests are done and the results completed, the powers that be make an Acceptance Decision, also known as the Go/No-Go decision. If the users are satisfied, it’s a «Go.» Otherwise, it’s a «No-go.» The testers consist of either people in the target market of potential buyers or a testing team of end-users that includes stakeholders and representatives of every https://globalcloudteam.com/ group in the organization. The acceptance test is focused on evaluating the software system against the customer’s requirements. The terms “functional test”, “acceptance test” and “customer test” are used more or less interchangeably. A more specific term “story test”, referring to user stories is also used, as in the phrase “story test driven development”.
What is User Acceptance Testing (UAT)? Examples
Acceptance testing is part of the V-Model, a model where processes run in a sequential manner resembling a “V.” V-Models are also called Verification and Validation models. User acceptance testing falls at the end of one of the “V” branches, the final step. It covers only the Black-Box testing process and hence the entire functionality of the product will be tested. 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.
However, the software has passed through three testing levels But still there are some minor errors which can be identified when the system is used by the end user in the actual scenario. The acceptance test cases are executed against the test data or using an acceptance test script and then the results are compared with the expected ones. Beta tests or the beta version of the application are normally open to the whole world . He should be independent and think as an unknown user to the system. Tester should be Analytical and Lateral thinker and combine all sort of data to make the UAT successful.
Alpha testingis the form of acceptance testing that takes place at the developer’s site. In VModel, User acceptance testing corresponds to the requirement phase of the Software Development life cycle. Developers code software based on requirements document which is their “own” understanding of the requirements and may not actually be what the client needs from the software. Whenever possible, the testing occurs in a «war room» or conference room sort where all participants assemble for a day and work through the list of acceptance test cases.
It improves requirement definition as client tests requirement definition according to his needs. These issues are verified against the requirements, and now the fine is charged for TCS . If the identified bug is not as per requirement, then blue-dart can go for the Request For Enhancement and Change Request .
Step Confirm Business Objectives met:
So, your end-user should be your first choice when looking for someone to test your software product. It is a crucial part of any software project and a step that is skipped at your own peril. After successful completion of all testing processes, testing team confirms that the software application is bug-free and it can be delivered to the client. But the project manager said we have to deliver the software within a given time.
For the best results, there’s a whole list of requirements that have to be adhered to during the user acceptance testing phase. The requirements vary according to the type of software and the business conditions connected to the product. However, it is of utmost importance for each product to set criteria for the UAT so that the entire operation is as successful as it can be. The purpose of acceptance testing is to determine if a product, feature, or any other system meets the determined requirements prior to its delivery. Acceptance test scenarios or acceptance tests’ major objectives are to verify that a system is compliant with the functional specifications and business requirements for delivery.
Beta testing, also known as field testing represents tests performed at the customers’ sites. Customers are using the product at their locations and provide feedback which is essential before releasing it to the general audience. The scope of the alpha testing is to test the operating system prior to its delivery to the customers. The tests are performed by internal staff in a testing environment before taking it to test at the customer’s site. Conducting UAT is more like taking user feedback for your product.
It provides early detection of bugs and other issues that can be easily identified by professionals testing in the development environment. He is skilled in test automation, performance testing, big data, and CI-CD. He brings his decade of experience to his current role where he is dedicated to educating the QA professionals.

Developers develop functions by examining the requirement document on their own understanding and may not understand the actual requirements of the client. Firstly, the basic tests are executed, and if the test results are satisfactory then the execution of more complex scenarios are carried out. Adam Carpenter is a tech, fintech, and business innovations writer. Passionate about user safety, Adam writes about cybersecurity solutions, software, and innovations. Tools for creating tests and managing their execution and results are also available. An example is Zephyr, which can be used with Jira to provide test management capabilities.
It is carried out after system testing and before the final delivery to the client. Identify the test scenarios with respect to high-level business process and create test cases with clear test steps. Test Cases should sufficiently cover most of the UAT scenarios.

Operational Acceptance Testing (OAT)
UAT is done in the final phase of testing after functional, integration and system testing is done. Operational acceptance testing is used to conduct operational readiness (pre-release) of a product, service or system as part of a quality management system. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. This type of testing focuses on the operational readiness of the system to be supported, and/or to become part of the production environment. Business Acceptance Testing – Business acceptance testing assesses the developed application from the perspective of business goals and processes.
UAT Test Planning
If a vendor expects its release to go worldwide, it must be tested by a diverse pool of users. Crowd testing is very effective, as it permits users from all over the world to join the testing, validate the product’s usefulness, and provide feedback. Sometimes, users don’t want to participate in the testing process. Feedback help in improving the product performance and user experience. Operational acceptance test criteria are defined in terms of functional and non-functional requirements; covering key quality attributes of functional stability, portability and reliability. Conducting acceptance testing must ensure that a system is compliant and sufficient for business usage.
In software development, UAT as one of the final stages of a project often occurs before a client or customer accepts the new system. Users of the system perform tests in line with what would occur in real-life scenarios. Acceptance criteria are a set of requirements, user needs, or business processes that determine whether or not a system should be approved. If acceptance criteria are satisfied upon testing, a decision is made if a new product, capabilities, features, services, etc. are accepted or not.
Prerequisites of User Acceptance Testing:
Some of the tests include functional, integration, and system. The team carries out the tests at different intervals of the project and with varying purposes. For example, functional testing only tests a specific function of the application. In system testing, the developers aim to test the entire app.
