Class Method Details

.allow_net_connect=(allowed) ⇒ Object

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.

end

.allow_net_connect?Boolean

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.

Returns:

  • (Boolean)

.clean_registryObject

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

.register_uri(*args) ⇒ Object

call-seq:

FakeWeb.register_uri(method, uri, options)

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:

:body

A string which is used as the body of the response. If the string refers to a valid filesystem path, the contents of that file will be read and used as the body of the response instead. (This used to be two options, :string and :file, respectively. These are now deprecated.)

:response

Either an Net::HTTPResponse, an IO, or a String which is used as the full response for the request.

The easier way by far is to pass the :response option to register_uri as a String or an (open for reads) IO object which will be used as the complete HTTP response, including headers and body. If the string points to a readable file, this file will be used as the content for the request.

To obtain a complete response document, you can use the curl command, like so:

curl -i http://www.example.com/ > response_for_www.example.com

which can then be used in your test environment like so:

FakeWeb.register_uri(:get, 'http://www.example.com/', :response => 'response_for_www.example.com')

See the Net::HTTPResponse documentation for more information on creating custom response objects.

options may also be an Array containing a list of the above-described Hash. In this case, FakeWeb will rotate through each provided response, you may optionally provide:

:times

The number of times this response will be used. Decremented by one each time it’s called. FakeWeb will use the final provided request indefinitely, regardless of its :times parameter.

Two optional arguments are also accepted:

:status

Passing :status as a two-value array will set the response code and message. The defaults are 200 and OK, respectively. Example:

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

The argument passed via :exception will be raised when the specified URL is requested. Any Exception class is valid. Example:

FakeWeb.register_uri('http://www.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")
