CapyDash

Minimal, zero-config HTML report for your RSpec and Minitest tests. Add the gem, run your tests, get a report.

Setup

Add it to your Gemfile:

group :test do
  gem "capydash"
end

Run bundle install. That's it — no configuration needed.

Usage

Run your tests as usual:

# RSpec
bundle exec rspec

# Minitest
bundle exec rails test
bundle exec rails test:system

After the suite finishes, open the generated report:

capydash_report/index.html

The report includes pass/fail counts, tests grouped by class, expandable error details with backtraces, and failure screenshots with a clickable lightbox.

Failure Screenshots

When a test fails and Capybara with a browser driver is available, CapyDash automatically captures a screenshot and embeds it in the report. Click the thumbnail to view the full-size image.

• RSpec — screenshot captured during after(:each), before session teardown
• Minitest — uses Rails' built-in failure screenshot from tmp/capybara/

No configuration needed. If Capybara isn't available, screenshots are silently skipped.

Requirements

• RSpec >= 3.0 or Minitest >= 5.0
• Ruby 2.7+

How It Works

CapyDash auto-detects your test framework and hooks in automatically:

• RSpec — registers before(:suite), after(:each), and after(:suite) callbacks via RSpec.configure
• Minitest — registers a reporter via the Minitest plugin system (start, record, report)

Results are collected in memory during the run and written as a static HTML report to capydash_report/ when the suite completes. Each run produces a fresh report — no server, no database, no config files.
