- UAT Testers (End-Users or Stakeholders): Responsibilities: Testers actively participate in executing UAT test cases, mimicking real-world scenarios. They assess the software’s functionality, usability, and overall performance based on their roles and responsibilities within the organization.
- UAT Test Manager or Coordinator: Responsibilities: The UAT test manager is responsible for planning and overseeing the entire UAT process. This includes defining test objectives, creating test plans, managing test resources, and ensuring that UAT is conducted according to schedule.
- Test Case Developers: Responsibilities: Test case developers create detailed UAT test cases based on the documented user requirements. They ensure that test cases are comprehensive and cover various usage scenarios.
- Defect Reporters: Responsibilities: Testers or users who identify defects during UAT are responsible for documenting these issues. They provide clear descriptions, steps to reproduce, and severity assessments for each defect.
Creating UAT Test Cases
- Understand User Requirements: Begin by thoroughly understanding the user requirements, user stories, or business specifications that define what the software should achieve. Collaborate closely with business analysts, product owners, and end-users to clarify any ambiguities and gain a deep understanding of the expected behavior.
- Identify Test Scenarios: Break down the UAT test cases into specific test scenarios, each focusing on a particular aspect or functionality of the software. Test scenarios should be based on real-world usage and should cover a variety of situations, including typical, edge, and error cases.
- Define Test Steps: For each test scenario, define a set of clear and concise test steps that outline the actions to be performed by the tester. Include detailed instructions, such as what data to enter, which buttons to click, and what results to expect.
- Specify Expected Results: Clearly state the expected results or outcomes for each test step. These expectations should be based on the user requirements and should be measurable and verifiable. Be specific about what success looks like and what constitutes a pass or fail for each step.
Executing UAT
| Execution Phase | Description |
|---|---|
| Test Environment Setup | – Ensure that the UAT environment is properly configured and mirrors the production environment as closely as possible. – Verify that all necessary hardware, software, and data are available and functioning correctly. |
| Test Data Preparation | – If your UAT test cases require specific test data, ensure that this data is available and ready for use. – Double-check that test data is representative of real-world scenarios and covers various use cases. |
| Test Case Selection | – Decide on the order in which you’ll execute your UAT test cases. You can follow a logical sequence or prioritize critical scenarios first. – Consider any dependencies between test cases and plan their execution accordingly. |
| Execution by Testers | – Assign specific test cases or scenarios to UAT testers or end-users who will actively participate in the testing process. – Testers should follow the test steps outlined in the test cases meticulously. – Encourage testers to mimic real-world usage as closely as possible, performing tasks and operations as they would during their regular activities. |
