And batch production and test work development of the attitude instrument are facilitated.

The present disclosure provides a data model automatic testing method and device and electronic equipment, and relates to the field of software testing. The method comprises the following steps: obtaining all attribute combinations of a plurality of preset attributes corresponding to a to-be-tested data model and a plurality of preset conditions, and determining all condition combinations corresponding to the to-be-tested data model according to the all attribute combinations and the plurality of preset conditions; obtaining preset attribute values of each preset attribute under each condition combination, and determining a first target result corresponding to each condition combination according to the preset attribute values of the preset attribute; generating a plurality of data requests corresponding to each condition combination respectively, and inputting the plurality of data requests into the to-be-tested data model to obtain a second target result corresponding to each condition combination output by the to-be-tested data model; and outputting an output test pass message of the to-be-tested data model when each second target result is equal to the first target result of the corresponding condition combination. The present disclosure can improve the comprehensive testing efficiency of the data model.

The utility model relates to a capacitor righting and testing integrated mechanism in the field of capacitor testing, which comprises a supporting seat, a righting station and a testing station are arranged on the supporting seat, the righting station is provided with a clamping and righting assembly for righting a capacitor, and the testing station is provided with a clamping and testing assembly for testing the righting capacitor. A clamping driver is arranged on the supporting seat, clamping ends are formed at the two ends of the clamping driver, and the clamping driver is connected with the righting and clamping assembly and the clamping and testing assembly through the clamping ends. The problem of large space occupation caused by separation of centralizing and testing equipment in a traditional scheme is solved, the space occupation and the equipment cost of multiple mechanisms are saved, meanwhile, the clamping driver can enable the clamping centralizing assembly and the clamping testing assembly to be controlled in a linkage mode, centralizing and testing of the capacitor can be completed under one-time driving of the clamping driver, and the clamping and testing efficiency is improved. And the test accuracy and reliability are improved.
