Functional testing is a quality assurance (QA) process and a type of black-box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (unlike white-box testing). Functional testing is conducted to evaluate the compliance of a system or component with specified functional requirements. Functional testing usually describes what the system does.

Method to locate logic errors and defects in digital circuits
When, in the course of an integrated circuit's functional test an assertion fires at clock k, the operational clock is stopped, the sequence is reapplied to capture inputs to the assertion circuit that fired, signals within the assertion circuit are computed, and the error is backtraced. Once one or more inputs of the assertion circuit are identified as potentially the source of the error, the process of backtracing is performed for each such input. When the input that is potentially the source of the error emanates from a memory circuit, the fanin cone of the memory circuit is identified and the process of backtracing through the last-identified fanin cone is undertaken for clock k−1. This is repeated iteratively until either a module of the integrated circuit is found to be the source of the error, or the error is extended to inputs of the SoC.

Location-based testing for wireless data communication networks
ActiveUS7539489B1Easy to optimizeFacilitate data communicationError preventionFrequency-division multiplex detailsTest stimulusSystem under test
Apparatus and methods facilitating a distributed approach to performance and functionality testing of location-sensitive wireless data communication systems and equipment are described. A plurality of test units, geographically distributed at arbitrary points in a three-dimensional volume surround the system or equipment under test. Each test unit generates test stimuli and records responses from the device under test, and emulates the effects of changes in spatial location within an actual wireless network environment. A central controller co-ordinates the set of test units to ensure that they act as a logical whole, and enables testing to be performed in a repeatable manner in spite of the variations introduced by the location sensitive characteristics of wireless data communication networks. The central controller also maintains a user interface that provides a unified view of the complete test system, and a unified view of the behavior of the system or equipment under test. For diagnostic purposes, the recorded responses may be regenerated to view any defects as many times as necessary to correct them. Alternatively, each test unit may have either wired network interface units, instead of a wireless interface unit to test systems or equipment forming part of a wired network portion in the wireless data communication system.

The NTT monitors the actions of the CTT and creates a script to mimic the actions of the CTT. The current test script is modified to add comments, and translated using standard translation tools. Application-specific statements do not translate and are replaced with those previously created by the NTT in the record mode.
