FakeWeb

Enables or disables real HTTP connections for requests that don’t match registered URIs.

If you set FakeWeb.allow_net_connect = false and subsequently try to make a request to a URI you haven’t registered with register_uri, a NetConnectNotAllowedError will be raised. This is handy when you want to make sure your tests are self-contained, or want to catch the scenario when a URI is changed in implementation code without a corresponding test change.

When FakeWeb.allow_net_connect = true (the default), requests to URIs not stubbed with FakeWeb are passed through to Net::HTTP.

If you assign a String, URI, or Regexp object, unstubbed requests will be allowed if they match that value. This is useful when you want to allow access to a local server for integration testing, while still preventing your tests from using the internet.

# File lib/fake_web.rb, line 41
def self.allow_net_connect=(allowed)
  case allowed
  when String, URI, Regexp
    @allow_all_connections = false
    Registry.instance.register_passthrough_uri(allowed)
  else
    @allow_all_connections = allowed
    Registry.instance.remove_passthrough_uri
  end
end

Returns true if requests to URIs not registered with FakeWeb are passed through to Net::HTTP for normal processing (the default). Returns false if an exception is raised for these requests.

If you’ve assigned a String, URI, or Regexp to FakeWeb.allow_net_connect=, you must supply a URI to check against that filter. Otherwise, an ArgumentError will be raised.

# File lib/fake_web.rb, line 62
def self.allow_net_connect?(uri = nil)
  if Registry.instance.passthrough_uri_map.any?
    raise ArgumentError, "You must supply a URI to test" if uri.nil?
    Registry.instance.passthrough_uri_matches?(uri)
  else
    @allow_all_connections
  end
end

Resets the FakeWeb Registry. This will force all subsequent web requests to behave as real requests.

# File lib/fake_web.rb, line 20
def self.clean_registry
  Registry.instance.clean_registry
end

Returns the request object from the last request made via Net::HTTP.

# File lib/fake_web.rb, line 196
def self.last_request
  @last_request
end

Register requests using the HTTP method specified by the symbol method for uri to be handled according to options. If you specify the method :any, the response will be reigstered for any request for uri. uri can be a String, URI, or Regexp object. options must be either a Hash or an Array of Hashes (see below), which must contain one of these two keys:

curl -i http://example.com > response_from_example.com

FakeWeb.register_uri(:get, "http://example.com", :response => "response_from_example.com")

options may also be an Array containing a list of the above-described Hash. In this case, FakeWeb will rotate through each response. You can optionally repeat a response more than once before rotating:

Two optional arguments are also accepted:

FakeWeb.register_uri(:get, "http://example.com", :body => "Go away!", :status => [404, "Not Found"])

FakeWeb.register_uri(:get, "http://example.com", :exception => Net::HTTPError)

If you’re using the :body response type, you can pass additional options to specify the HTTP headers to be used in the response. Example:

FakeWeb.register_uri(:get, "http://example.com/index.txt", :body => "Hello", :content_type => "text/plain")

You can also pass an array of header values to include a header in the response more than once:

FakeWeb.register_uri(:get, "http://example.com", :set_cookie => ["name=value", "example=1"])

# File lib/fake_web.rb, line 150
def self.register_uri(*args)
  case args.length
  when 3
    Registry.instance.register_uri(*args)
  when 2
    print_missing_http_method_deprecation_warning(*args)
    Registry.instance.register_uri(:any, *args)
  else
    raise ArgumentError.new("wrong number of arguments (#{args.length} for 3)")
  end
end

Returns true if a method request for uri is registered with FakeWeb. Specify a method of :any to check against all HTTP methods.

# File lib/fake_web.rb, line 183
def self.registered_uri?(*args)
  case args.length
  when 2
    Registry.instance.registered_uri?(*args)
  when 1
    print_missing_http_method_deprecation_warning(*args)
    Registry.instance.registered_uri?(:any, *args)
  else
    raise ArgumentError.new("wrong number of arguments (#{args.length} for 2)")
  end
