Watchdog Dashboard is a Rails engine that provides a visual interface for monitoring the performance and reliability of your RSpec tests. This dashboard is part of the RspecWatchdog ecosystem but is specifically designed to integrate with Rails applications.

• Metrics Visualization: Charts and tables to analyze your test execution times
• Flaky Test Detection: Identify tests that fail intermittently
• Trend Tracking: Monitor the health of your test suite over time
• Comprehensive Statistics: Visualize data such as total runs, failures, and average test times
• Simple Integration: Easy to set up in any existing Rails application

[You can include some screenshots of the dashboard here]

gem 'watchdog-dashboard'

Then run:

bundle install

bin/rails watchdog_dashboard:install:migrations
bin/rails db:migrate

In config/routes.rb, add:

mount Watchdog::Dashboard::Engine => "/watchdog"

This will make the dashboard available at /watchdog in your Rails app.

Create a configuration file in config/initializers/watchdog_dashboard.rb:

Watchdog::Dashboard.configure do |config|
  config.watchdog_api_token = "your_secret_token" # Change this to a secure value
end

To get the maximum benefit, you should use Watchdog Dashboard together with the RspecWatchdog gem, which handles data collection during your test execution.

Configure RspecWatchdog in your spec/rails_helper.rb:

require "rspec_watchdog"

RspecWatchdog.configure do |config|
  config.show_logs = true
  config.watchdog_api_url = "http://localhost:3000/watchdog/analytics"
  config.watchdog_api_token = "your_secret_token" # Must match the dashboard token
end

RSpec.configure do |config|
  config.add_formatter(:progress) # Default RSpec formatter
  config.add_formatter(SlowSpecFormatter)
end

Important: Make sure that the watchdog_api_token matches between RspecWatchdog and Watchdog::Dashboard.

This token is used to validate that requests sent to the dashboard API are legitimate.

• If you're running tests in a CI/CD environment (e.g., GitHub Actions or CircleCI), you can set this value as an environment variable.
• For development environments, you can use a constant value, but make sure not to include it in version control.

Once configured, the dashboard will be available at /watchdog and will display:

• Main Panel: Summary of key metrics and general trends
• Slow Tests: List of tests that take longer to execute
• Flaky Tests: Identification of tests that fail intermittently
• Execution History: Tracking of all test runs
• Settings: Adjustments to customize the dashboard

To make the most of Watchdog Dashboard in a CI/CD environment:

1. Configure the token as a secure environment variable in your CI/CD platform
2. Ensure your tests send data to the correct endpoint
3. Use the dashboard to analyze trends after each CI run
