4.6. test


    The "test" operation tests that a value at the specified location in
    the target document is equal to a specified value.  The operation
    object contains a "value" member, which specifies the value to test
    for.  If values are or contain objects or arrays, they must be
    identical (i.e. same order of elements, with the same values).

    Example:

    { "test": "/a/b/c", "value": "foo" }

    It is an error condition if the value at the specified location is
    not equal to the specified value.

Note the last paragraph.
