By constructing a test scenario close to the actual operating environment, the performance of the board to be tested can be comprehensively evaluated, thereby ensuring the accuracy of the performance evaluation and improving the comprehensiveness and accuracy of the performance test. Moreover, since the vibration mechanism is arranged in the test slot, the heating mechanism is installed above the vibration mechanism, and the test mechanism is arranged adjacent to the conveying mechanism, that is, the vibration mechanism and the heating mechanism are both arranged adjacent to the test mechanism, not only the independent environment simulation of the board to be tested is realized, but also the influence of temperature fluctuation or vibration interference on the performance of the test probe is effectively reduced by physically separating the environmental simulation from the test mechanism, thereby ensuring the accuracy of the performance test results of the board to be tested.
