rspec-instrumentation

RSpec instrumentation

RSpec instrumentation component to measure performances, profile and monitor the test suite using an external service.

DISCLAIMER: this is an initial version, major changes will probably happens in the first releases

Support for:

• New Relic
• Sentry APM (partial for now)

Setup the gem, execute the test suite, check the results in the service interface.

Install

• Add to the Gemfile (in the test group): gem 'rspec-instrumentation'
• Follow the specific instructions below per service

New Relic

• Configure New Relic on your application (also adding the gem 'newrelic_rpm' to the Gemfile)
• Add an initializer in your app (config/initializers/new_relic.rb) with:

RSpecInstrumentation::NewRelic.setup if Rails.env.test?

• Add to your rails_helper.rb (or spec_helper.rb):

# It's better to put in at the end, after the other configuration options
RSpec.configure do |config|
  RSpecInstrumentation::RSpec.setup(config, service: :new_relic)
end

• If you are using VCR, depending on your configuration you could need also to permit external requests to the New Relic service, example:

VCR.configure do |config|
  config.ignore_hosts 'collector-001.eu01.nr-data.net' # the host could be different for your account
end

Do you like it? Star it!

If you use this component just star it. A developer is more motivated to improve a project when there is some interest.

Or consider offering me a coffee, it's a small thing but it is greatly appreciated: about me.
