Recently, our team of Business Analysts and Quality Assurance specialists faced a real challenge. 

We were asked to lead a challenging User Acceptance Testing process for a client in the fintech sector. The complexity of the project stemmed from the involvement of numerous stakeholders and diverse teams, each with distinct priorities and expectations. Navigating through the complexities of regulatory requirements, security protocols, and user experience considerations unique to the fintech domain was a real challenge for the team. Despite these challenges, the strategic approach led to a successful UAT process, and our team has gained valuable insights. In this article, we'll show you step by step how to approach UAT effectively.

1. Preparation and Planning

a. Define UAT Objectives:

  • Establish clear objectives for UAT. These could include verifying the app’s functionality, performance, security, and user experience.
  • Ensure that the objectives align with the business requirements and user expectations.

b. Identify Key Stakeholders:

  • Involve key stakeholders such as business analysts, project managers, QA teams, and end users.
  • Assign roles and responsibilities to each stakeholder to streamline the UAT process.

c. Develop a UAT Plan:

  • Create a detailed UAT plan that outlines the scope, objectives, timeline, and resources required.
  • Include a risk management plan to address potential issues that may arise during testing.

d. Gather Requirements:

  • Collect and document all business and technical requirements.
  • Ensure that these requirements are clear, complete, and testable.

2. Designing Test Cases and Scenarios

a. Identify Key Business Processes:

  • Focus on the critical business processes of the banking app, such as account management, transaction processing, fund transfers, and security features.

b. Develop Test Scenarios:

  • Create high-level test scenarios that represent real-world usage of the app.
  • Ensure that the scenarios cover both common and edge cases.

c. Write Detailed Test Cases:

  • Develop detailed test cases based on the identified scenarios.
  • Each test case should include a unique ID, description, preconditions, test steps, expected results, and actual results.

Example Test Case:

  • Test Case ID: TC-101
  • Test Case Description: Verify successful login with valid credentials.
  • Preconditions: User must have a valid username and password.
  • Test Steps:some text
    1. Open the banking app.
    2. Enter invalid username and password.
    3. Click on the login button.
    4. Enter valid username and password.
    5. Click on the login button.
  • Expected Results: User is logged in and redirected to the dashboard.
  • Bugs: (To be filled after execution)
  • Status: (Pass/Fail)
  • Comments: (Any additional notes)

d. Include Negative Testing:

  • Ensure that your test cases include negative testing to check how the app handles invalid inputs or unexpected user behavior.

3. Setting Up the UAT Environment

a. Prepare the Test Environment:

  • Set up a test environment that mirrors the production environment as closely as possible.
  • Ensure that the test environment is stable and accessible to all testers.

b. Create Test Data:

  • Prepare realistic test data that covers all possible variations.
  • Ensure that the test data is anonymized and does not contain any sensitive information.

c. Install the App:

  • Ensure that you install it after successful deployment of the latest version to the test environment.
  • Ensure that the app is properly configured and all dependencies are met.

4. Executing Test Cases

a. Conduct a Pilot Test:

  • Perform a pilot test with a small group of users to identify any major issues before the full-scale UAT. It can be done internally with you QA specialists or Product Owners within your organization 
  • Use the feedback from the pilot test to make necessary adjustments.

b. Execute Test Cases:

  • Execute the test cases according to the defined scenarios.
  • Record the status of each test case (Pass/Fail) and provide detailed comments for any failures.

c. Log any Bugs:

  • Log any bugs or issues found during testing in Jira or other software that's used within your organisation.
  • Include detailed information about the defect, such as steps to reproduce, screenshots, and severity.

d. Prioritize bugs 

  • Decide on which bugs are most important to fix and give them a high priority status (P1, P2)

e. Retest and Regression Testing:

  • Once the bugs are fixed and deployed to the test environment perform retesting to ensure that the issues are resolved.
  • Conduct regression testing to verify that the fixes have not introduced any new issues.

5. Reviewing and Reporting

a. Analyze Test Results:

  • Review the test results to identify any patterns or common issues.
  • Analyze the overall test coverage and ensure that all critical functionalities have been tested.

b. Prepare a UAT Report:

  • Create a comprehensive UAT report that summarizes the testing activities, results, and any defects found.
  • Include recommendations for improvement and highlight any high-priority issues that need to be addressed before deployment.

c. Conduct a Review Meeting:

  • Organize a review meeting with stakeholders to discuss the UAT findings.
  • Ensure that all stakeholders understand the results and agree on the next steps.

6. Finalizing UAT and Preparing for Deployment

a. Obtain Sign-Off:

  • Once the UAT is complete and all critical issues are resolved, obtain formal sign-off from the stakeholders.
  • Ensure that the sign-off is documented and includes any remaining known issues and their impact.

b. Prepare for Deployment:

  • Plan the deployment activities, including final checks, backup procedures, and rollback plans.
  • Ensure that the production environment is ready for the app deployment.

c. Conduct a Post-UAT Review:

  • After the app is deployed, conduct a post-UAT review to evaluate the UAT process.
  • Identify any areas for improvement and document lessons learned for future projects.

Conclusion

User Acceptance Testing is a critical step in ensuring the success of any product. By following a structured and detailed approach, you can effectively validate that the product meets the users’ requirements and is ready for deployment. Engage stakeholders, design comprehensive test cases, execute tests thoroughly, and communicate findings clearly to achieve a successful UAT. Through careful planning and execution, your app will be well-positioned to deliver a secure, reliable, and user-friendly experience to your customers.
