How to mock a argument pass to the method + minitest - minitest

Question

I'm working on a test case wherein I want to check the integrity of the argument pass to the method.
Here how my controller code looks like.
def show
response = begin
site = Site.find_by(id: params[:id])
site.bonsai_site_configuration
rescue StandardError => exception
ExceptionNotifier.notify_exception(exception)
{}
end
render json: response, status: 200
end
Now, all I want to ensure that when I mock the find_by and to return site object I need the argument to match exactly what I intend it to be.
over here {id: site.id}
This is how my test currently looks like. I'm not very much familiar with minitest so would request you to please have patience with me. As I'm not entirely sure if the below code(test) is the correct way to write a minitest test.
test 'Services::SiteController: Show: Return `{}` as Site configuration on error' do
mock = MiniTest::Mock.new
mock.expect :call, true, [RuntimeError]
site = Site.first
site_mock = MiniTest::Mock.new
site_mock.expect :call, site, [{id: site.id}]
raises_exception = Proc.new { raise 'boom' }
Site.stub(:find_by, site_mock) do
site.stub(:bonsai_site_configuration, raises_exception) do
ExceptionNotifier.stub(:notify_exception, mock) do
get "/switch/sites/#{site.id}",
headers: { Authorization: "Basic b2576d705c208c19fd1601ef58aa0506bd4e2e93c51c19df856483cbbfc7cb67" }
response = JSON.parse(#response.body)
assert_successful_response
assert_empty(response)
end
end
end
assert_mock site_mock
assert_mock mock
end

Ok, there are 2 ways to test this.
Firstly, I was correct the
site_mock.expect :call, site, [{id: site.id}]
is the correct way to test this behaviour all I needed to change is.
site_mock.expect :call, site, [{id: site.id.to_s}]
The other way to test this is.
site_mock.expect :call, site do |*args|
args[0][:id] == site.id
end
