A test member is configured to abut against the photovoltaic module and apply a preset load to the photovoltaic module, to simulate force on the photovoltaic module when an operator walks on a surface of the photovoltaic module, so as to easily adjust and replace the material and the manufacturing process of the photovoltaic module according to test results, so that the photovoltaic module has stronger anti-stepping performance, thereby prolonging the service life of the photovoltaic module. The test member is provided with an abutment surface for abutting against the photovoltaic module, and an area S of the abutment surface satisfies: 50 cm2≤S≤400 cm2, which improves accuracy and reliability of the test results of the test device, thereby improving operation performance of the test device.
