What happens when you add a project?
Generally, pretty much what you’d expect if you were implementing this yourself:
- Using the permissions you gave CircleCI when you signed up, we’ll add some GitHub or Bitbucket settings to your project:
- A deploy key—used to check out your project from GitHub or Bitbucket
- A service hook—used to notify CircleCI when you push to GitHub or Bitbucket
- CircleCI immediately checks your code out onto our machines, infers your settings from your code, and runs your first build.
Our inference algorithms look through your dependencies, Gemfile, libraries, and code to figure out how to run your tests. For example, we might find that you have a standard Rails project using Postgres specifications and features, so we’ll run:
bundle install bundle exec rake db:schema:load bundle exec rspec spec bundle exec cucumber
We run your tests on a clean virtual machine every time. This means that:
- Your code isn’t accessible to other users
- We run your tests freshly each time you push
- You can watch your tests update in real-time on your dashboard.
- We’ll send you a notification when you’re done.
