Alpha Testing Introduction

We have learned a lot about software testing and its various types, where all of these sub-types focus on the process of executing an application or product to find bugs in your product. It can e considered as the investigation carried out to offer stakeholders the information related to the quality of software being developed and tested. In this chapter, you will be learning about the two most essential and frequently uses testing methodologies - the alpha and beta testing techniques. Alpha Testing can be defined as a form of acceptance testing carried out to identify various types of issues or bugs before publishing the build or executable of the software public or market. This test type focuses on real users through black box and white box testing techniques. The focus remains on the task which a general user might want or experience. Alpha testing any product is done when product development is on the verge of completion.

Alpha and Beta Testing

Alpha Testing is a type of software testing performed to identify bugs before releasing the software product to the real users or public. It is a type of acceptance testing. The main objective of alpha testing is to refine the software product by finding and fixing the bugs that were not discovered through previous tests. This testing is referred to as an alpha testing only because it is done early on, near the end of the development of the software, and before Beta Testing. Check Differences between Alpha testing and Beta testing Alpha testing is typically performed by in-house software engineers or QA staff.

The focus of this testing is to simulate real users by using BlackBox and WhiteBox techniques. The aim is to carry out the tasks that a typical user might perform. Alpha testing is testing of an application when development is about to complete. Minor design changes can still be made as a result of alpha testing. It is carried out in a lab environment at the developers site. Developers observe the users and note problems.

Alpha testing is conducted in the organization and tested by a representative group of end-users at the developer's side and sometimes by an independent team of testers. Alpha testing is simulated or real operational testing at an in-house site. It comes after the unit testing, integration testing, etc. Alpha testing used after all the testing are executed. It can be a white box, or Black-box testing depends on the requirements - particular lab environment and simulation of the actual environment required for this testing. Alpha testing ensures that the software performs flawlessly and does not impact the reputation of the organization; the company implements final testing in the form of alpha testing. This testing executed into two phases.

Software Engineering

Alpha Testing is a type of software testing performed to identify bugs before releasing the product to real users or to the public. Alpha Testing is one of the user acceptance testing. Beta Testing is performed by real users of the software application in a real environment. Beta testing is one of the type of User Acceptance Testing. Attention reader!

Have you ever wondered what the terms alpha and beta meant in software testing? And what about the gamma? These terms originate back from the time the first commercial data processing machines were used. The hardware first went through an initial alpha test for testing the preliminary functionality of the product. Then came into existence the beta test which included people other than the developers to verify the end-user functionality.

Тогда они оба подумали, что он где-то допустил ошибку, но сейчас-то она знала, что действовала правильно. Тем не менее информация на экране казалась невероятной: NDAKOTA ETDOSHISHA. EDU - ЕТ? - спросила Сьюзан. У нее кружилась голова.  - Энсей Танкадо и есть Северная Дакота.

Сначала она не увидела ничего, кроме облаков пара. Но потом поняла, куда смотрел коммандер: на человеческую фигуру шестью этажами ниже, которая то и дело возникала в разрывах пара. Вот она показалась опять, с нелепо скрюченными конечностями. В девяноста футах внизу, распростертый на острых лопастях главного генератора, лежал Фил Чатрукьян. Тело его обгорело и почернело. Упав, он устроил замыкание основного электропитания шифровалки. Но еще более страшной ей показалась другая фигура, прятавшаяся в тени, где-то в середине длинной лестницы.

 - Сейчас найду. Вот. Все прочитали: - Разница в весе незначительна… разделяются вследствие газовой диффузии… 10,032498X10134 в сравнении с 1939484X1023.

 Сьюзан, - тихо сказал Стратмор, - с этим сначала будет трудно свыкнуться, но все же послушай меня хоть минутку.  - Он прикусил губу.  - Шифр, над которым работает ТРАНСТЕКСТ, уникален. Ни с чем подобным мы еще не сталкивались.  - Он замолчал, словно подбирая нужные слова.

На затекших ногах Беккер прошел через вращающуюся дверь. Больше никаких мотоциклов, пообещал он. Ярко освещенное помещение аэровокзала сияло стерильной чистотой.
