What is the difference between client side testing versus server side testing when we are execute various tests such as white box or black box testing?
as per my question, i am wondering what differences are there when we are performing tests for the client side , as compared to performing tests on the client side?

For example, testing javascript on the client side versus testing server side code?

Best Regards.
