An instance of this class represents a set of requests and responses performed sequentially by a test process. Because you can instantiate multiple sessions and run them side-by-side, you can also mimic (to some limited extent) multiple simultaneous users interacting with your system.

Typically, you will instantiate a new session using IntegrationTest#open_session, rather than instantiating Integration::Session directly.

host()

The hostname used in the last request.

end

https!(flag = true)

Specify whether or not the session should mimic a secure HTTPS request.

process(method, path, params: nil, headers: nil, env: nil, xhr: false, as: nil)

Performs the actual request.

  • method: The HTTP method (GET, POST, PATCH, PUT, DELETE, HEAD, OPTIONS) as a symbol.

  • path: The URI (as a String) on which you want to perform the request.

  • params: The HTTP parameters that you want to pass. This may be nil, a Hash, or a String that is appropriately encoded (application/x-www-form-urlencoded or multipart/form-data).

  • headers: Additional headers to pass, as a Hash. The headers will be merged into the Rack env hash.

  • env: Additional env to pass, as a Hash. The headers will be merged into the Rack env hash.

  • xhr: Set to true if you want to make an Ajax request. Adds request headers characteristic of XMLHttpRequest e.g. HTTP_X_REQUESTED_WITH. The headers will be merged into the Rack env hash.

  • as: Used for encoding the request with different content type. Supports :json by default and will set the appropriate request headers. The headers will be merged into the Rack env hash.

This method is rarely used directly. Use get, post, or other standard HTTP methods in integration tests. process is only required when using a request method that doesn’t have a method defined in the integration tests.

This method returns the response status, after performing the request. Furthermore, if this method was called from an ActionDispatch::IntegrationTest object, then that object’s @response instance variable will point to a Response object which one can use to inspect the details of the response.

Example:

process :get, '/author', params: { since: 201501011400 }

reset!()

Resets the instance. This can be used to reset the state information in an existing session instance, so it can be used from a clean-slate condition.
