4 bit counter testing

Hello, I am trying to test a 4 bit counter eg 74160 for open/shorts and leakage currents

Here is what I am thinking
For the open shorts I ground the vcc and ground pins, I apply a 100uA current and measure the voltage on the pins

For short/open to vcc I was thinking if the voltage stays between .2V and 1.5V, there is no short or open
less than .2 = short
more than 1.5 = open

For the leakage current I apply provide power through vcc and ground
Then add a voltage (5.5 V ) to the pin in question (inputs and outputs?) and measure current

My question is if those tests look okay? I don't know if the voltages currents are good for the 74160, any tips greatly appreciated.
I don't have much experience reading the datasheets and I didn't find information about the protection diodes in it

Thanks!
