Beta Testing: A more extensive test than the Alpha, performed by real users and customers. The purpose of Beta testing is to determine how the product performs in an actual user environment. It is critical that real customers perform this evaluation, not the firm developing the product or a contracted testing company. As with the Alpha test, results of the Beta Test should be carefully evaluated with an eye toward any needed modifications or corrections.
贝塔测试:与阿尔法测试相比，是测试维度更为广泛的一种测试方法，由实际使用者和消费者来施行。其目的是判断在实际使用环境中产品的性能如何。其关键是，该项测试应由实际消费者来完成，而不是由公司开发团队或外包测试公司来完成。同阿尔法测试一样，必须认真对待贝塔测试的结果，从而找出产品所需的任何修正。
