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

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.

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 }
