0.6.0

Features

• Added linear number of queries assertion.

Now you can set up an expectation of linear growth of the number of queries. It can be helpful when you already have N+1 and for some reason you cannot fix it right now, so you want to prevent it from growing. Example:

# RSpec

context "when has linear query", :n_plus_one do
  populate { |n| create_list(:post, n) }

  specify do
    expect { Post.find_each { |p| p.user.name } }
      .to perform_linear_number_of_queries(slope: 1)
  end
end

# Minitest

def test_no_n_plus_one_error
  populate = ->(n) { create_list(:post, n) }
  
  assert_perform_linear_number_of_queries(slope: 1, populate: populate) do
    Post.find_each { |p| p.user.name }
  end
end

Fixes

• Added support for backticks in table names.

If your rails application uses backticks around table names in database queries, they will be correctly processed in verbose mode.
