What does UAT (User Acceptance Testing) is defined as?

​User Acceptance Testing

Definition

• User Acceptance Testing (UAT) is a type of testing performed by the end user or the client to verify/accept the software system before moving the software application to the production environment.

​User Acceptance Testing

Definition

• User Acceptance Testing (UAT) is a type of testing performed by the end user or the client to verify/accept the software system before moving the software application to the production environment.

• UAT is done in the final phase of testing after functional, integration and system testing is done.

• To validate end to end business flow. It does not focus on cosmetic errors, spelling mistakes or system testing.

• UAT is carried out in a separate testing environment with production-like data setup.

• It is kind of black box testing where two or more end-users will be involved.

UAT = User Acceptance Testing

What happens if there is no UAT?

(Why is UAT important?)

• In a typical project, there would always be gaps of understanding between the 'requirements' and what is being built by the developers.

• In a typical project, there would always be gaps of understanding between the 'requirements' and what is being built by the developers.

• ​Once the software has undergone Unit, Integration and System testing, it may be successful because the built software is based on requirements document by their own understanding.

• ​Once the software has undergone Unit, Integration and System testing, it may be successful because the built software is based on requirements document by their own understanding.

• The problem arises when the software is delivered to the users and is not what is needed nor agreed by them.

What happens if there is no UAT?

• 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.

• Requirements changes during the course of the project may not be communicated effectively to the developers.

Remember the timed discussions?

How did your last 'discussion' with your fellow client go?

What did you feel, think and what was the outcome?

1. Business Requirements must be available.

2. Application Code should be fully developed

3. Unit Testing, Integration Testing & System Testing should be completed

4. No Showstoppers, High, Medium defects in System Integration Test Phase

So, what do we need for UAT?

4. No Showstoppers, High, Medium defects in System Integration Test Phase

5. Only Cosmetic error is acceptable before UAT

6. Regression Testing should be completed with no major defects

7. All the reported defects should be fixed and tested before UAT

8. Traceability matrix for all testing should be completed

8 Steps to Perform UAT

One of the most important activities in the UAT is to identify and develop test scenarios.

​

These test scenarios are derived from the following documents:

• Project Charter

• Business Use Cases

• Process Flow Diagrams

• Business Requirements Document(BRD)

• System Requirements Specification(SRS)

UAT = User Acceptance Testing

1: Analysis of Business Requirements

Image Source: Guru99

• The UAT test plan outlines the strategy that will be used to verify and ensure an application meets its business requirements.

• It documents entry and exit criteria for UAT, Test scenarios and test cases approach and timelines of testing.

UAT = User Acceptance Testing

2: Creation of UAT Plan

Image Source: Guru99

• 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. Business Use cases are input for creating the test cases.

3 & 4: Identify Test Scenarios and Test Cases

• 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. Business Use cases are input for creating the test cases.

5: Preparation of Test Data

Image Source: Guru99

• Execute test cases and report bugs if any.

• Re-test bugs once fixed.

• Some projects may utilise Test Management tools to fasten the execution.

6 & 7: Run Test Data & Record Results

Before moving into production, following needs to be considered:

• No critical defects open

• Business process works satisfactorily

• UAT Sign off meeting with all stakeholders

• Plan for system t​raining and off-boarding of system

8: Confirm business objectives​

What do you think would happen when there is NO TRAINING conducted in Step 8?

1. Prepare UAT plan early in the project life cycle

2. Prepare Checklist before the UAT starts

3. Conduct Pre-UAT session during System Testing phase itself

4. Set the expectation and define the scope of UAT clearly

5. Test End to End business flow and avoid system tests

6. Test the system or application with real-world scenarios and data

7. Think as an Unknown user to the system

8. Perform Usability Testing

9. Conduct Feedback session and meeting before moving to production

9 Best Practices for UAT

Image Source: Guru99

• Based on the criteria, we (QA team) give them the users a list of UAT test cases.

• These test cases are not different from our regular system test cases. They are just a subset as we test all of the applications as opposed, just to the key functional areas.

• The data, templates to record test results, administrative procedures, defect logging mechanism, etc., has to be in place before we move to the next phase.

Conclusion

• In Software Engineering, UAT is short for User Acceptance Testing.

• ​UAT happens in between 'Testing' and 'Maintenance' in the SDLC.

• UAT is one of the many types of testing that has emerged over the last twenty-five years.

• With UAT, the client can be sure “What to expect” from the product rather than assuming.

• The benefit of UAT is that there will be no surprises when the product is released to the market.
