如何在rspec测试期间启动辅助Rails应用程序？

Question

I have 2 rails apps. One is a web interface (I'll call it UI ), the other one is an API server (I'll call it API ).

They interact together, UI is sending json commands to API. I want to test all of this in integration. Today I manually start API from the command line, and I am looking for a way to automatically start the API server from the test suite.

I am using Capyraba, Selenium, Rspec. During the tests Capybara automatically starts a UI server, I need to also start a API server.

Any hint appreciated. Thanks

I tried Process.spawn("cd /api/project/path && rails s -e test") but I get a ActionController::RoutingError: No route matches error saying that the path in API is not existing. But when I run API manually I don't have this error.

I believe Rack is getting confused with 2 environments

You need to ensure that API is running before your scenarios are started. You can add rule to start it if it is not running by adding in before hook:

#features/supports/app_life_cycle_hooks.rb
Before do |scenario|
  start_api()   
end

def start_api()
 Process.spawn("./script/server start")
end
