To Alpha, it is also known as Beta test which is testing for one or more software users in the actual use environment. Developers are usually not at the test scene, Beta testing cannot be completed by the programmers or testers. Thus, Beta testing is the software scene application which the developer can not control the environment.

In Beta testing, users record all the problems and report them to the developers regularly; on receiving the Beta testing report, the developers comprehensively analyze all the problems and make the final changes to system, then deliver software products to all users. Beta testing focuses on product support, including documentation, customer training and support for production capacity. Only when the Alpha test reached a certain level of reliability, can begin Beta testing. Beta testing because the main objective was to test support, so Beta testing the product should, as far as possible from the staff to manage the issue.

Beta testing has to be done for many reasons.

First, as the test scenarios and test data limited, not to test all aspects, and the user behavior is diverse, many users of the test can not think of or to simulate the use of Beta testing to monitor the good of a user These acts so that the software more stable and robust.

Second, Beta version testing is conducive to the latter part of the upgrading of products. Beta test version of the market is also one of the means test, can be collected to the software products related to more demand, in order to constantly improve the inadequacies of the software, and the development of more effective use of new features.

Third, customers of products are often the first impression of his decision on the product evaluation. Basically, Beta test the response, most customers will be the response. Beta testing through the development of the process, learn to test the feelings of the product, classification and record test the response to the packaging of products, information communication in grasping the right direction, what information should be strengthened, and what information should be diluted, to Primary and secondary clear. This also helps a lot for product marketing.
