webmock-disabler is a gem that allows users of WebMock to disable and re-enable WebMock on-demand. This is useful in testing scenarios where the mere presence of WebMock causes some tests to fail. A common case is that the presence of WebMock is known to cause failures in Selenium-based integration tests, such as RSpec's request specs and Cucumber features.
The blog post introducing webmock-disabler is here.
gem install webmock-disabler
or, if you use Bundler
webmock-disabler works by monkey patching WebMock, so, its implementation is understandably fragile. It was written against version 1.6.4 of WebMock, and it might work with higher 1.x versions. Then again, it might not.
If future versions of WebMock break webmock-disabler, file an issue about it, or, better yet, fork, fix, and send a pull request.
While WebMock can mock out lots of different HTTP libraries (Net::HTTP, HTTPClient, EventMachine::HttpRequest, and more), webmock-disabler only supports Net::HTTP. So if you're using any HTTP library other than Net::HTTP, don't expect webmock-disabler to do squat.
I have no plans to implement support for other HTTP libraries, but I do have plans to accept pull requests- so have at it.
require 'webmock' require 'webmock-disabler' Net::HTTP.get(URI.parse('http://www.google.com')) => raises WebMock::NetConnectNotAllowedError WebMock.disable! Net::HTTP.get(URI.parse('http://www.google.com')) => the HTML at www.google.com WebMock.enable! Net::HTTP.get(URI.parse('http://www.google.com')) => raises WebMock::NetConnectNotAllowedError
Usage with RSpec
In your spec_helper.rb:
before(:each), :type => :request do WebMock.disable! end after(:each), :type => :request do WebMock.enable! end
