User acceptance testing / UAT Testing Explained
User Acceptance Testing or UAT Testing is the last step prior to completion of any application. It is the responsibility of end users using these applications. They test these applications prior to inherit that application to their side. This type of testing is helpful for any end users. It boosts up their confidence as they are sure they will be getting an application with expected results. This kind of testing also help the bugs to be keep away from the application without interfering it.
Prerequisites of UAT Testing
Application is fully developed prior to user acceptance testing. In User acceptance testing, there are many levels of testing performed. Before you come to start user acceptance testing, all these three level of testing are completed. This is the reason as most of the errors and defects are already been solved until it arrives to UAT stage.
What to test in UAT
For an effective and useful user acceptance testing, you need to create test cases. In requirement definition stage, you will find ample of use cases and you can use them to make your test cases. These test cases help you understand that all major scenarios and situations have been covered within them.
When you start with user acceptance testing, your aim is on what is the real world usage of the application that is being developed. You carry on testing in production environment. Then the test cases are formed using real world scenarios.
How to test in UAT
If you want to know how to use User acceptance testing, then you should have some knowledge on black box testing. User acceptance testing is something like black box testing, where the goal is on function and use of application. This testing does not take care of any technical knowledge. When you get application for User acceptance testing, it is assumed that they have passed all other testing like unit till system testing.
It is best when user acceptance testing is carried out in environment that is the actual world. It is here that end users could get good benefit with an effective application that is being developed.
1) Planning in User Acceptance test: This is the essential phase that outlines the testing strategy. Main focus area, that is entry point as well as exit points are described here. This could be the most effective step if proper planning is done.
1) Design made for UA test cases: Test cases are the sources that help the testing team in testing the complete application effectively. There are use cases that are being created in requirement definition stage of software testing. These use cases serves as a source of test case designing. Later on business analyst and other experts of team revise these test cases thoroughly.
2) Selection of team executing UAT test cases: This is a major step as proper execution team would help in easy and effective running and testing of application. This team represents the actual world users who would be benefitted from the application. Hence, the team has the actual end users who would be making use of the application that is being developed.
3) Execution of test cases: The test engineers carries out all the test cases.
4) Documentation of defects found in UAT: If any kind of defects or bugs is found in application, then the team in comments from lists those.
5) Bug fixing and resolving issues: The issues or bugs that are found in UAT are cleared out with team of project, business analyst and all other team experts. According all suggestions and mutual consents, these errors and bugs are resolved.
6) Signing off: Once there is an error free completion of user acceptance testing, the application is being indicated as being accepted by end users. This is one of the important steps for commercial purpose. Once users indicate that they have accepted the application, it is known whether that application meets the software requirements. The step makes the developers sure that this application can be delivered to vendors easily.

Key deliverable in user acceptance testing
When you look at traditional software life cycle, you find that bug and error free completion of application is a major step. Some of the major deliverables of user acceptance testing phase are described here:
1) Test plan: Here, step where test strategy is being developed.
2) User Applications Test cases: These test cases are responsible for effectively testing the application at end user.
3) Test Log: This is a place where all test results are executed and actual results are described.
4) User signing off: Products are delivered to full satisfaction is distinguished by this testing field.
In user acceptance testing a group of end users are testing the application with the real world scenario.
Why to carry on User Acceptance testing
The user acceptance testing is carried to protect any organization from harm and danger. There could be many risk involved in installing any software on your computer. To go in details there are main reasons for performing UAT are due to many risks that may be involved with your organization. These risks are:
1) Legal risk: System might break any rule leading your organization to legal bounding.
2) Time risk: Business deadlines may not be met by the system. This must be discussed in testing phase rather than in live phase.
3) Resource risk: Lots of resources may be expended in working around the system and all these may add cost but no value. It is better to carry on testing to avoid any resource risk.
4) Reputation risk: This is the main risk due to which User acceptance testing should be done. This is done to avoid any risk involved with the end users and customers who would be using the software application developed by your organization. With UAT, all these risks could be avoided.

User Acceptance testing (UAT) is very important as it helps in proper conduction of tests and freeing your software application from every bugs and errors. This testing helps your organization to be away from any harm and danger that may be incurred to your organization.
