Overview

Enforces the test to use ‘assert_instance_of(Class, object)` over `assert(object.instance_of?(Class))`.

Examples:

# bad
assert(object.instance_of?(Class))
assert(object.instance_of?(Class), 'message')

# bad
assert_equal(Class, object.class)
assert_equal(Class, object.class, 'message')

# good
assert_instance_of(Class, object)
assert_instance_of(Class, object, 'message')
