Beta testing comes after alpha testing and can be considered a form of external user acceptance testing. Versions of the software, known as beta versions, are released to a limited audience outside of the programming team known as beta testers.
The focus of beta testing is reducing impacts on users, often incorporating usability testing. The process of delivering a beta version to the users is called beta release and is typically the first time that the software is available outside of the organization that developed it.
A/B testing (also known as bucket testing, split-run testing, or split testing) is a user experience research methodology. [1] A/B tests consist of a randomized experiment that usually involves two variants (A and B), [2] [3] [4] although the concept can be also extended to multiple variants of the same variable.
Software performance testing. In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. [1] It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as ...
In probability theory and statistics, the beta-binomial distribution is a family of discrete probability distributions on a finite support of non-negative integers arising when the probability of success in each of a fixed or known number of Bernoulli trials is either unknown or random.
Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms , and to protect the heart from a second heart attack after a first heart attack (secondary prevention).
The Beta Test is a 2021 dark comedy thriller film written and directed by Jim Cummings and PJ McCabe. It follows a talent agent whose life is turned upside-down after taking part in a secret sex pact; Cummings and McCabe star alongside Virginia Newcomb and Jessie Barr.
The beta distribution is a suitable model for the random behavior of percentages and proportions. In Bayesian inference, the beta distribution is the conjugate prior probability distributionfor the Bernoulli, binomial, negative binomial, and geometricdistributions.

Betacoronavirus (β-CoVs or Beta-CoVs) is one of four genera ( Alpha -, Beta-, Gamma-, and Delta-) of coronaviruses. Member viruses are enveloped, positive-strand RNA viruses that infect mammals, including humans. The natural reservoir for betacoronaviruses are bats and rodents. Rodents are the reservoir for the subgenus Embecovirus, while bats ...
