NOne

Copy Markdown View Source

Detect repeated Ecto query fingerprints inside logical operation boundaries.

Install

{:n_one, "~> 0.1.0", only: [:dev, :test], runtime: false}
NOne.watch("reviews.index", fn ->
  Reviews.list_reviews(workspace)
end)

Configure the Repo telemetry events to watch:

config :n_one,
  repos: [MyApp.Repo],
  mode: :log,
  max_repeats: 3

Use the Phoenix plug to watch request boundaries without wrapping query functions:

plug NOne.Plug

Use the ExUnit helper for focused regression tests:

import NOne.ExUnit

assert_no_repeated_queries "reviews.index", max_repeats: 1 do
  Reviews.list_reviews(workspace)
end
