In engineering and its various subdisciplines, acceptance testing is black-box testing of a system (eg software, lots of manufacture of mechanical parts, or batches of chemical products) prior to its delivery. In others, it is known that functional testing, black box testing, release acceptance, testing, quality assurance, application testing, confidence testing, testing, validation, testing of acceptance or factory.
In software development, acceptance testing by the supplier of the system is often distinguished from acceptance testing by the customer (the user or the client) before accepting the transfer of ownership. In such environments, the trials to acceptance by the customer is known as the test user acceptance (UAT). This is also known as end-user testing, the site (acceptance) test or field (acceptance) testing.
Overview
Acceptance testing generally involves running a series of tests on the completed system. Each test, known as cases, exercises a state of operation of the user's environment or feature of the system and will result in a pass or fail boolean outcome. There is generally no degrees of success or failure. The test environment is usually designed to be identical or as close as possible, provided the user to the environment, including such extremes. These test cases must each be accompanied by test case input data or a formal description of operational activities (or both) to achieve, to thoroughly exercise the specific case and a description of the results.
Acceptance Tests / Criterion (in Agile Software Development) are usually created by customers and expressed in a business language. These are high-level tests to test the compliance of a story or user stories "played" during any sprint / iteration. These tests are created preferably through collaboration between customers, business analysts, testers and developers, but business customers (product owners) are the primary owners of these tests. When the user passes the stories of their acceptance criteria, business owners can be sure that the developers are progressing in the right direction on how the application was intended to work and it is therefore essential that These tests include tests of logic, and interface elements of validation (if required).
Acceptance of test cards are perfectly created during sprint planning and iteration planning meeting, before the development so that developers have a clear idea of what to develop. Sometimes (because of poor planning) tests in May of multiple stories (that are not implemented in the same sprint) and there are different ways to test them during the sprint. A popular technique is to mock external interfaces or data to mimick other stories that could not be played during an iteration (as these stories May were relatively lower priority). A history of the user is not considered complete until the acceptance tests have passed.
Process
Following acceptance test is directed against the entry of data or by using a test script to direct acceptance testers. Then, the results are compared with the results. If there is a good match for all cases, the test suite is said to pass. If not, the system May be either accepted or rejected in conditions previously agreed between the developer and builder.
The aim is to give confidence that the system of record of meeting the needs of both authors and users. The acceptance phase May also act as a gateway to the quality, where no quality defects to be detected in May uncovered.
A main goal of acceptance testing is that, once successfully completed, and provided that certain other (contract) are met acceptance criteria, the authors then sign on the system as satisfying the contract ( prior agreement between developer and manufacturer), and deliver final payment.
Types of acceptance testing
The types of acceptance testing are
Acceptance testing by the user
This May include acceptance testing at the factory, ie the testing facility by users before the plant is moved to its own site, after which the site acceptance testing be performed in May by users on the site.
Operational acceptance testing
Also known as operational readiness test, it is the de facto control to a system to ensure that processes and procedures are in place to allow the system to be used and maintained. This May include controls to safeguard the facilities, procedures for disaster recovery, training for end users, maintenance procedures and safety procedures.
Contract and regulation acceptance testing
Contract acceptance testing, a system is tested against the criteria for acceptance as a contract, before the system is accepted. In regulation acceptance testing, a system is tested to ensure it meets governmental, legal and safety standards.
Alpha and beta test
Alpha testing is carried out at site developers, and testing of the operating system by the staff before it is delivered to external customers. Beta testing is done to clients sites, and testing by a group of customers who use the system to their own sites and feedback before the system is handed over to other customers. This is often called the "field testing".
