Field testing refers to testing techniques that operate in the field to reveal those faults that escape in-house testing. Field testing techniques are becoming increasingly popular with the growing complexity of contemporary software systems. In this article, we present the first systematic survey of field testing approaches over a body of 80 collected studies, and propose their categorization based on the environment and the system on which field testing is performed. We discuss four research questions addressing how software is tested in the field, what is tested in the field, which are the requirements , and how field tests are managed , and identify many challenging research directions.

现场测试技术综述

现场测试是指在现场操作以揭示那些逃避内部测试的故障的测试技术。随着当代软件系统日益复杂，现场测试技术变得越来越流行。在本文中，我们对 80 项收集的研究进行了首次系统性的现场测试方法调查，并根据环境和执行现场测试的系统提出了它们的分类。我们讨论了四个研究问题如何软件经过现场测试，什么在现场进行了测试，它们是要求，以及现场测试的方式管理，并确定许多具有挑战性的研究方向。
