Answer 1

There is a difference between the property that is present, but having null value, and the property not being present at all.

If the test should fail only when there is a non-null value, use:

.andExpect(jsonPath("password").doesNotExist())

If the test should fail as soon as the property is present, even with a null value, use:

.andExpect(jsonPath("password").doesNotHaveJsonPath())
