Yes in most cases you can use the metal casing of the USB plug to check end to end continuity. The metal casing is connected to a fine braided shielding end to end
A multimeter set to Ohms x100 will go full scale when tested end to end
I just tested a couple of different cables and brands
USB2A male to USB2A male
USB3A to USB3B
USB2A to USB2A female
And so on …….
And all tested fine with a continuity test
In my Obs all my USB cables are labelled, makes life so much easier when replacing or fault finding
Although I suspect some “el cheapo” USB cables may not have a shielding end to end
