The invention relates to a method and a device for testing an application program. The method for testing the application program comprises the following steps: acquiring a source code of the application program under test, and precompiling the source code of the application program under test on the basis of a test script complied advance; compiling the source code of the precompiled application program under test to generate an application program; running the generated application program, and outputting test information. According to the method and the device provided by the invention, during precompiling, according to the test script of aspect oriented programming, a debugging code for test is dynamically inserted into the source code of the application program under test; when the application program is run, the test information is output on the basis of the debugging code, and therefore, location and quality measurement can be performed on the bug of the application program according to the test information; as the source code of the application program under test does not need to be modified, the product defect and performance risk of the application program cannot be caused; while the validity test of the application program is realized, the maintainability of the code under test is improved.

The invention provides a method and a device for updating a product defect detection model, a storage medium and terminal equipment. The method comprises the following steps: receiving a first detection model generated by training; replacing the second detection model in a detection system with the first detection model, and making the ratio of the number of servers running the first detection model to the number of servers running the second detection model in the detection system after replacement conform to a replacement proportion; calculating the detection accuracy of the detection systembefore replacement and the detection accuracy of the detection system after replacement; and if the detection accuracy of the detection system after replacement is higher than the detection accuracyof the detection system before replacement and the difference is greater than an adjustment threshold, adjusting the replacement proportion based on a preset proportional step size increment, replacing the second detection model in the detection system with the first detection model, and making the ratio of the number of servers running the first detection model to the number of servers running the second detection model in the detection system after replacement conform to the replacement proportion after incremental adjustment. According to the invention, the applicability and detection accuracy of the detection model can be improved.

The invention provides a novel disc type permanent magnet motor against the defects in the existing production and manufacturing process of an armature of the disc type permanent magnet motor, which is characterized in that a stator component is in a slotless structure or a coreless structure; an armature winding for generating electrical excitation is fixed on a stator, and a stator winding is in a printed circuit board structure; a magnetic pole of a rotor is made of permanent magnet material; and the motor does not comprise an electric brush and a commutator. By adopting the technical scheme, not only the production and manufacturing process of an iron core can be simplified, but also the processes, such as winding, paying off, wire connecting and the like can be simultaneously saved, thereby simplifying the manufacturing process of the armature of the disc type permanent magnet motor, which is complex originally, and bringing convenience to automatic mass production by using a machine. The disc type permanent magnet motor has the advantages of being convenient to mount, saving working time, being high in production efficiency, being firm in structure, being low in failure rate, reducing product defects caused by human factors, being applicable to mass production and being low in cost.
