UAT and Agile Development

In the dynamic landscape of software development, agility has emerged as the guiding principle for innovation. The integration of User Acceptance Testing (UAT) within Agile methodologies has given rise to a symbiotic relationship that propels the development process towards excellence. This fusion not only accelerates software delivery but also enhances user satisfaction through a continuous cycle of testing and refinement.

Integrating UAT within Agile methodologies

Agile methodologies, characterized by their iterative and incremental approach, emphasize adaptability and collaboration. Integrating UAT seamlessly aligns with these principles, infusing the development cycle with user-centricity. In Agile, UAT is not an isolated event at the end of development but an ongoing process. As each iteration progresses, UAT becomes a checkpoint where user feedback is sought and incorporated, steering the software towards alignment with user needs. The use of acceptance criteria in the agile software development process makes for the inclusion of UAT like verifications.

There are two choices to integrate UAT as part of Agile:

  1. You treat it as “release to production” and the Product Owner contacts the users or Business Analyst to test the functionality in UAT.
  2. You treat it as part of the development. Then it should be in Definition of Done, and it should be part of the Product Backlog Item’s flow to “Done” i.e. To Do -> In Progress -> UAT -> Done.

UAT’s role in continuous delivery and frequent releases

Agile’s hallmark is continuous delivery and frequent releases. UAT plays a pivotal role in ensuring that these releases are not just swift but also polished. With UAT as a recurring step, each release undergoes meticulous user scrutiny. This process is a buffer against the introduction of defects and glitches, safeguarding the user experience. As Agile embraces change, UAT steps in to validate changes, making certain that they resonate positively with users.

The team’s Definition of Done should be such that downstream activities, such as integration or user acceptance testing, complete successfully. If the result of user acceptance testing is that the product is not acceptable, the team should understand why and make changes to their way of working to regularly create Increments that are likely to be acceptable. Any other feedback from UAT can be treated like customer or user feedback and ordered with the rest of the Product Backlog.

By removing external dependencies, you no longer need to worry about how to estimate or plan for these external dependencies during refinement or Sprint Planning events.

Moreover, UAT’s involvement in the Agile cycle nurtures a culture of collaboration. Developers, testers, and end-users converge, where user feedback shapes the software’s evolution. This real-time engagement refines the software, nurturing a product that evolves organically with user needs.

UAT is the final stage of the development process to determine that the software does what it was designed to do according to the requirements originally stated.

  2. What is UAT vs QA testing?

    UAT and QA both involve testing. However, they have different objectives. The difference is that the QA teams work to ensure error-free software whereas UAT ensures that end users get the product they want. QA teams generally perform system integration testing while business analysts perform UAT.

  3. What is UAT in agile?

    UAT, or user acceptance testing, is the final stage in the software testing process. In Agile as well as waterfall projects, it is typically performed by the end-users, clients or business analysts to determine whether an application or feature fulfills its purpose. UAT must be completed before the software can be released to the market. UAT can be performed within a sprint or before a production release.

  4. What tool is used for UAT?

    With the help of Selenium, testers can automate the acceptance tests, ensuring that the application meets the requirements of the end users. However, it's important to note that Selenium alone may not be sufficient for all aspects of UAT and may need to be combined with other tools for a complete UAT solution. JIRA is also typically used to manage and maintain test cases.

  5. What is UAT in DevOps?

    User acceptance testing (UAT) is the last phase of the software testing process. During UAT, actual software users test the software to make sure it works as per real-world scenarios, and according to the requirements. DevOps incorporates the practice of UAT to allow for seamless delivery of high quality software products.

  6. Who prepares UAT?

    User acceptance testing is performed by business analysts, clients or the end-users. They will write a complete UAT test plan, prepare a UAT environment that mirrors production, write corresponding UAT test cases, execute these test cases, report defects if any, verify the fixes to the defects raised and finally confirm that the software is fit for use.

  7. Is UAT part of Agile?

    UAT is included in the agile framework, and should be part of the sub tasks for each use story in the product backlog. A user story describes a user, the feature they want to use, and how it helps them achieve their goal, and the UAT tests should describe an explain the acceptance criteria.

  8. Who manages UAT in Agile?

    This could be the Business Analyst or Product Owner. But because the ability to produce a “Done” increment would be so tightly coupled to this process, a Development Team should certainly take an interest in making sure UAT takes place at the right time and in the right way to maximize what they are able to achieve.
