UAT (User Acceptance Testing)

User Acceptance Testing (UAT) is the final phase of the Software Testing Life Cycle (STLC). It ensures that the delivered system meets user requirements and is ready for deployment in a production environment. UAT focuses on validating the software from an end-user perspective, simulating real-world usage scenarios to ensure the system behaves as intended.


Purpose of UAT

1. Validation: Confirms the software aligns with the functional requirements defined during earlier phases.


2. Quality Assurance: Identifies overlooked defects or usability issues.


3. Stakeholder Confidence: Involves end-users to establish trust in the system before deployment.


4. Risk Mitigation: Reduces the risk of post-deployment issues by addressing potential problems earlier.



UAT Process

The UAT process is well-structured, emphasizing collaboration and thorough validation.

1. Planning Phase:

Define the scope of UAT based on the Functional Requirements Document (FRD).

Identify test cases and user stories to validate.

Assemble a team of business users, quality analysts, and developers.



2. Test Environment Setup:

Prepare a production-like environment with real-world data.

Ensure necessary tools, test scripts, and configurations are in place.



3. Test Case Design:

Use real-world scenarios to craft test cases.

Include both positive tests (expected use) and negative tests (edge cases).

Prioritize usability, performance, and compliance validation.



4. Execution:

Users execute test cases, documenting outcomes.

Report any bugs or issues identified.



5. Defect Resolution:

Log defects in a tracking tool (e.g., JIRA).

Developers address reported issues.

Retest resolved issues to ensure compliance.



6. Approval and Sign-Off:

Upon successful completion of UAT, stakeholders sign off, approving the system for deployment.




Sample UAT Document

Below is an example of a simple UAT document template.


User Acceptance Testing Plan

1. Overview

Project Name: Customer Portal Upgrade

Objective: Validate system functionality against defined requirements.

Participants: Business users, QA team, and developers.


2. Scope

Modules to Test: User authentication, account management, and transaction history.

In-Scope Data: Real-world customer datasets.


3. Test Cases
| Test Case ID | Description                  | Expected Outcome                | Status  |
|————–|——————————|———————————-|———|
| UAT001       | Login with valid credentials | User navigates to the dashboard | Passed  |
| UAT002       | Login with invalid password  | Error message is displayed      | Passed  |
| UAT003       | View transaction history     | List of transactions is shown   | Failed  |

4. Test Results Summary

Total Test Cases: 20

Passed: 18

Failed: 2

Comments: Retesting required for transaction module.


5. Approval

Sign-Off By: Project Manager, Business Lead

Date: [Insert Date]



Key UAT Challenges

1. Inadequate User Involvement: Insufficient user input can lead to overlooked critical scenarios.


2. Unrealistic Test Data: Failing to use real-world data may hide potential defects.


3. Scope Creep: Expanding UAT scope mid-process can delay project timelines.


4. Time Constraints: Limited testing time compromises thorough defect identification.



Importance of UAT in SDLC

Enhances Usability: Ensures the software is intuitive for end-users.

Reduces Costs: Early identification of defects minimizes post-deployment fixes.

Facilitates Change Management: Involves users, easing adoption and reducing resistance to change.


User Acceptance Testing is a critical phase in SDLC, emphasizing real-world validation to ensure system success. By engaging end-users and following a structured process, UAT ensures a seamless transition from development to production, delivering a high-quality, user-centric solution.
