You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: instance_scope_test.rb
    path of file: ./repos/active_model_cachers/test
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require 'base_test'

class InstanceScopeTest < BaseTest
  def test_basic_usage
    user = User.find_by(name: 'John1')

    assert_queries(1){ assert_equal true, user.cacher.has_post2? }
    assert_queries(0){ assert_equal true, user.cacher.has_post2? }
    assert_cache('active_model_cachers_User_at_has_post2?_1' => true)
  end

  def test_without_association_cache
    user1 = User.find_by(name: 'John1'
    
  def test_destroy
    user = User.create(name: 'John5')
    post = Post.create(user: user)

    assert_queries(1){ assert_equal true, user.cacher.has_post2? }
    assert_queries(0){ assert_equal true, user.cacher.has_post2? }
    assert_cache("active_model_cachers_User_at_has_post2?_#{user.id}" => true)

    assert_queries(1){ post.destroy }
    assert_cache({})

    assert_queries(1){ assert_equal false, user.cacher.has_post2? }
    assert_queries(0){ assert_equal false, user.cacher.has_post2? }
    assert_cache("active_model_cachers_User_at_has_post2?_#{user.id}" => ActiveModelCachers::FalseObject)
  ensure
    user.delete
    post.delete
  end
