Acceptance testing is formal testing based on user requirements and function processing. It determines whether the software is conforming specified requirements and user requirements or not. It is conducted as a kind of Black Box testing where the number of required users involved to test the acceptance level of the system. It is the fourth and last level of software testing.
However, the software has passed through three testing levels (Unit Testing, Integration Testing, System Testing) But still there are some minor errors which can be identified when the system is used by the end user in the actual scenario.
Acceptance testing is the squeezing of all the testing processes that have done previously.
Reason behind Acceptance Testing
Once the software has undergone through Unit Testing, Integration Testing and System Testing so, Acceptance Testing may seem redundant, but it is required due to the following reasons.
Steps to Perform Acceptance Testing
In this step, the testing team analyzes requirement document to find out the objective of the developed software. Test planning accomplished by using requirement document, Process Flow Diagrams, System Requirements Specification, Business Use Cases, Business Requirements Document and Project Charter.
Test Plan Creation:Test Plan Creation outlines the whole strategy of the testing process. This strategy is used to ensure and verify whether the software is conforming specified requirements or not.
Test Case Designing:This step includes the creation of test cases based on test plan documents. Test cases should be designed in a way that can cover most of the acceptance testing scenario.
Test Case Execution:Test Case Execution includes execution of test cases by using appropriate input values. The testing team collects input values from the end user then all test cases are executed by both tester and end user to make sure software is working correctly in the actual scenario.
Confirmation of objectives:After successful completion of all testing processes, testing team confirms that the software application is bug-free and it can be delivered to the client.
Tools used in Acceptance Testing
Acceptance Testing can be done by using several tools; some are given below:
done by using several tools; some are given below:
Acceptance testing uses this tool for the execution of automated browser-based test cases. It uses Ruby language for the inter-process communication.
This tool is used to enter input values and generate test cases automatically. The user needs to input values, these values used by the tool to execute test cases and to produce output. It uses Java language for the inter-process communication. This tool makes it easy to create test cases as well as record them in the form of a table.
Advantages of Acceptance Testing
Disadvantages of Acceptance Testing
According to the testing plan, the customer has to write requirements in their own words and by themselves but
If the process is done in this manner, it destroys the existence of the Acceptance Testing.
