“…Field testing was first considered an opportunity to deal with failures that were hard or too costly to reproduce in the laboratory, with a few studies in the nineties addressing autonomic systems [51,100], and real-time issues [98]. It attracted then steady interest in the early years of the first decade of this century, with a sudden burst of results from 2007 on, mostly pushed by the advent of service-oriented architectures, which lacked centralized control for testing purposes.…”

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.

“…Duplication (also called Cloning) [6], [8], [17] consists of cloning the execution state (e.g., by forking a parallel process [17]) and executing in-vivo tests on the cloned execution state, hence ensuring that there is no interference with the end user execution of the application (in-memory side effects are prevented, but of course other side effects on persistent storage are not dealt with). Another proposed isolation mechanism is Test mode execution [3], [10], [12], [14], [21]. It requires a way to differentiate between the execution of a component in normal operation mode vs. the testing mode.…”

“…It requires a way to differentiate between the execution of a component in normal operation mode vs. the testing mode. In the latter case, counter measures are taken to ensure that test mode execution does not affect the normal execution state (e.g., by tagging invocations and data with a test tag [12], [13]). Another clean and elegant solution consists of using a transactional memory [4].…”

The ecosystem in which mobile applications run is highly heterogeneous and configurable. All layers upon which mobile apps are built offer wide possibilities of variations, from the device and the hardware, to the operating system and middleware, up to the user preferences and settings. Testing all possible configurations exhaustively, before releasing the app, is unaffordable. As a consequence, the app may exhibit different, including faulty, behaviours when executed in the field, under specific configurations.In this paper, we describe a framework that can be instantiated to support in-vivo testing of a mobile app. The framework monitors the configuration in the field and triggers in-vivo testing when an untested configuration is recognized. Experimental results show that the overhead introduced by monitoring is unnoticeable to negligible (i.e., 0-6%) depending on the device being used (high-vs. low-end). In-vivo test execution required on average 3s: if performed upon screen lock activation, it introduces just a slight delay before locking the device.

Widely distributed systems are constructed step-bystep over a long time. These systems must permit online testing. On-line testing verifies newly added application software by receiving the real data in the real environment without disrupting the operating subsystems. To enable testing during system operation, a n on-line test technique based on autonomous decentralized syst e m structure was proposed. In this paper, the functions t o verify various types of application software are proposed: (1) f o r non-real-time application software, checking whether it communicates with every operating application software. (2) f o r real-time application software, checking whether timing of output data is within the timing-deadline or not. (3) f o r n e w version software, verifying whether the version of all functions is newer than that of functions in the present software. An ezample of application software applied t o the online test and the effectiveness of the technique is shown in a real system.
