Features

Navigation helpers

Jump from any Rails file to its counterpart.
When multiple candidates exist a Telescope picker opens automatically.

From	To	Key
model / controller / view	model	<leader>rm
model / view / test	controller	<leader>rc
model / controller	view	<leader>rv
model / controller	test / spec	<leader>rs

Inertia + React support – when navigating to a view (<leader>rv) from a controller that uses render inertia:, the plugin resolves the matching .jsx / .tsx component under app/frontend/pages/ automatically.

Test runner

Supports both minitest (test/) and RSpec (spec/) projects.

Run specs/tests without leaving the editor.
Results (pass ✅ / fail ❌) are shown inline in the buffer as virtual text and diagnostics.

Action	Key
Run whole test file	<leader>rt
Clear test results	<leader>rX

RSpec requires no extra setup.
Minitest requires minitest-json-reporter and minitest 5.x (minitest 6+ is not yet compatible):

# Gemfile
gem "minitest", "~> 5.25"

group :test do
  gem "minitest-json-reporter"
end
