Coverage test support device and coverage test support method

摘要

To provide a technique which can effectively detect a bug of an optional program created by machine learning.SOLUTION: A coverage test support apparatus 100 has an external storage apparatus 101, a memory 103, a CPU 104, an input apparatus 105, an output apparatus 106, and an external medium input/output apparatus 107. The storage apparatus stores a test case 1111 and a regulation contents 1171 of a plurality of coverage indexes, and so on. The CPU executes a predetermined number of tests on a program 1101 originating from a neural network by successively giving a test input value of each pair in a test case, obtains test results and neuron information at the time of test execution, applies the neuron information to the regulation contents of each of multiple coverage indicators, calculates values of each coverage indexes, and specifies, if either of the number of executed tests or the number of bags in test results exceeds a predetermined reference, as a priority coverage index, one of values of coverage indexes having a vale of a growth rate indicating a predetermined tendency.SELECTED DRAWING: Figure 2
