A control system includes at least one processor and at least one memory. The at least one processor is configured to determine operation data by repeating a process of calculating control target data indicating a predicted value of a control target in a plant and the operation data indicating an operation value of a control device of the plant by a given calculation model based on observation data indicating an actual value of the plant.

The possibility of a desired program being automatically generated is increased by a program generation device including: a generation unit configured to generate a first program that satisfies at least one pair of an input value and an output value; and a determination unit configured to randomly generate an input value that satisfies a constraint regarding input and output of the first program, and determine whether or not an output value that is obtained by inputting the input value to the first program satisfies the constraint.

The possibility of a desired program being automatically generated is increased by a program generation device including: a storage unit that stores a set of pairs each constituted by a program and natural language that describes a specification of the program; a search unit configured to search for a first program having a structure that is the closest to a structure of a program to be generated, from the set, by inputting natural language that describes a specification of the program to be generated and natural language included in the pairs to a model that has been caused to learn a relationship between natural language describing a specification of a program and similarity of a structure of the program; and a change unit configured to change the first program to generate a second program that satisfies at least one pair of an input value and an output value.

An apparatus and a method relate to generating a test scenario for testing a web application. The disclosure includes executing a script that causes a transition of a screen to a reference screen of the web application. From the reference screen, the disclosure dynamically performs a screen transition analysis for subsequent screens that are transitioned from previous screens of the web application. The subsequent screens for the dynamically performing the screen transition analysis are within a boundary according to a predetermined number of hops from the reference screen. The screen transition analysis includes automatically generating a test scenario and input data for causing screen transitions in the web application. Based on the screen transitions, the screen transition analysis generates screen transition data diagram for testing the web application.

The possibility of a desired program being automatically generated is increased by a program generation device including: a search unit configured to search for a first program that corresponds to a specification written in natural language similar to natural language that describes a specification of a program to be generated, from a set of pairs each constituted by natural language that describes a specification of a program and the program that satisfies syntax of a programing language; and a change unit configured to change the first program to generate a second program that satisfies at least one pair of an input value and an output value.

An input value setting assistance device includes: an acquisition unit that displays a first screen including a plurality of input fields, and acquires an image of the first screen and a coordinate value regarding each of the input fields included is the first screen; and an assistance unit that displays a second screen including the image acquired by the acquisition unit regarding the first screen and setting fields for setting values for each of the input fields of the first screen and, when one of the setting fields is selected, displays a prescribed mark based on the coordinate value acquired by the acquisition unit for the input field related to the setting field. Thereby, the setting work of each of the input values prepared in advance for each of the input fields included is the screen can be effectively assisted.

An operation pattern generation apparatus has a generating unit which generates, with respect to a test script to be used for a web application, operation patterns related to combinations of operation elements that cause a transition between screens of the web application and input data candidates for input elements to be used to input data on the screens, and with respect to the input element of which a default value of input data is set in advance, the generating unit combines only the default value with the operation elements in order to reduce time required for specification restoration of screen transitions of the web application.

A test data generation device that generates test data to be input into an input field of a test target application includes a storage unit that stores a tacit knowledge test data dictionary including, for each tacit knowledge category, a generation method, test data information, and an input value constraint on an input field to be used as a generation condition, and a generation unit that refers to, regarding a certain tacit knowledge category for a target input field, the tacit knowledge test data dictionary to generate test data for the target input field when an input value constraint of the target input field in the test target application and an input value constraint of a generation condition regarding the tacit knowledge category are determined to match, and not to generate the test data for the target input field when the input value constraint of the target input field and the input value constraint of the generation condition regarding the tacit knowledge category are determined not to match.
