Real request handling

Real requests to network can be allowed or disabled

WebMock.allow_net_connect!

stub_request(:any, "www.example.com").to_return(body: "abc")

Net::HTTP.get('www.example.com', '/')    # ===> "abc"

Net::HTTP.get('www.something.com', '/')    # ===> /.+Something.+/

WebMock.disable_net_connect!

Net::HTTP.get('www.something.com', '/')    # ===> Failure

External requests can be disabled while allowing localhost

WebMock.disable_net_connect!(allow_localhost: true)

Net::HTTP.get('www.something.com', '/')    # ===> Failure

Net::HTTP.get('localhost:9887', '/')    # ===> Allowed. Perhaps to Selenium?

External requests can be disabled while allowing specific requests

Allowed requests can be specified in a number of ways.

With a String specifying a host name:

WebMock.disable_net_connect!(allow: 'www.example.org')

RestClient.get('www.something.com', '/')    # ===> Failure
RestClient.get('www.example.org', '/')      # ===> Allowed
RestClient.get('www.example.org:8080', '/') # ===> Allowed

With a String specifying a host name and a port:

WebMock.disable_net_connect!(allow: 'www.example.org:8080')

RestClient.get('www.something.com', '/')    # ===> Failure
RestClient.get('www.example.org', '/')      # ===> Failure
RestClient.get('www.example.org:8080', '/') # ===> Allowed

With a Regexp matching the URI:

WebMock.disable_net_connect!(allow: %r{ample.org/foo})

RestClient.get('www.example.org', '/foo/bar') # ===> Allowed
RestClient.get('sample.org', '/foo')          # ===> Allowed
RestClient.get('sample.org', '/bar')          # ===> Failure

With an object that responds to #call, receiving a URI object and returning a boolean:

blacklist = ['google.com', 'facebook.com', 'apple.com']
allowed_sites = lambda{|uri|
  blacklist.none?{|site| uri.host.include?(site) }
}
WebMock.disable_net_connect!(allow: allowed_sites)

RestClient.get('www.example.org', '/')  # ===> Allowed
RestClient.get('www.facebook.com', '/') # ===> Failure
RestClient.get('apple.com', '/')        # ===> Failure

With an Array of any of the above:

WebMock.disable_net_connect!(allow: [
  lambda{|uri| uri.host.length % 2 == 0 },
  /ample.org/,
  'bbc.co.uk',
])

RestClient.get('www.example.org', '/') # ===> Allowed
RestClient.get('bbc.co.uk', '/')       # ===> Allowed
RestClient.get('bbc.com', '/')         # ===> Allowed
RestClient.get('www.bbc.com', '/')     # ===> Failure
