6results about How to "Avoid testing errors" patented technology

The invention discloses an isolation device interface test system and test method. The test system comprises a control platform used for generating a corresponding control signal according to a currently selected test item; the test equipment is used for simulating the aerial carrier platform according to the control signal and generating a corresponding test signal; and the test adapter plate is used for transferring a test signal to a port corresponding to the isolation device interface, and returning return data fed back by the port to the control platform through the test equipment, so that the control platform can generate a test result according to the return data. According to the invention, the test equipment can be built by adopting test equipment with lower cost, and compared with an expensive aerial carrier platform, the test cost is greatly reduced; the control platform can perform analysis, measurement and calculation and generate the test result according to the return data fed back by the tested port, manual test is not needed, the test efficiency can be obviously improved, and test errors caused by manual operation are reduced or even avoided.

The invention discloses a circuit detection method and device in chip testing, and belongs to the technical field of chip testing. The method comprises the following steps: respectively distributing corresponding target voltage amplitudes for a plurality of digital input / output (DIO) channels between test equipment and a test circuit board; when the actual voltage value of each DIO channel in the plurality of DIO channels is within a preset range, displaying a prompt that the channel connection is correct on a test interface, and starting a subsequent test program; or when the actual voltage value of at least one DIO channel in the multiple DIO channels is not within the preset range, a prompt of channel connection errors is displayed on the test interface, and starting of the follow-up test program is interrupted. According to the method, after the target voltage amplitude is distributed, the actual voltage value in each channel is detected to judge the line connection state, the test is interrupted in time when the connection fails, test errors caused by line connection errors are effectively prevented, and the chip test efficiency and reliability are improved.

The embodiment of the application provides a test tool, which comprises: a first base, a first force applying mechanism, a first clamping assembly and a supporting assembly are arranged on the first base, and the supporting assembly is used for supporting a component to be tested; a second base is arranged at a distance from the first base along the height direction of the first base, a second force applying mechanism and a second clamping assembly are arranged on the second base, the first clamping assembly is arranged opposite to the first clamping assembly, so that a clamping space is formed between the second clamping assembly and the first clamping assembly, and the clamping space is used for accommodating a fixed end of the component to be tested; the second base moves towards the first base along the height direction of the first base, can drive the second force applying mechanism to move synchronously, and then drives at least part of the first force applying mechanism to move along the stress direction of the component to be tested, so as to test the stress of the component to be tested. The scheme solves the problem that the test tool in the prior art cannot test the components whose forming direction is inconsistent with the stress direction.

The invention provides a front-end page test method and device, a storage medium and computer equipment, and the method comprises the steps: determining a to-be-tested front-end page and a corresponding recording script when a test instruction is received, then using the recording script to carry out playback test on the front-end page, and in the playback process, when a preset action is triggered, carrying out the playback test on the front-end page. According to the method, a current front-end page is subjected to screenshot to obtain a source image, a target image in a recording script is matched with the source image to determine a corresponding region of the target image on the source image, a region to be tested is positioned through image matching, and a test result is determined in combination with the target image during recording. In this way, the situation that the recorded script is frequently updated due to the fact that the elements are positioned based on the attributes of the page elements can be avoided, the maintenance cost for testing the front-end page is reduced, meanwhile, test errors caused by untimely updating can be avoided, and the test accuracy is ensured.

The present disclosure relates to a technology related to an automated analysis system using individually operated biological devices, an analysis method, and a storage medium, wherein the system and the method enable an analysis sample to be prepared and analyzed by operating together with an automated analysis system through the operative connection of stand-alone devices.
