"Can't GET /XXX" error while using swagger-express - rest

Question

I'm using swagger-express for making RESTful API. Base /hello route works fine, but I tried to add some more sophisticated one, with database connection etc. Whenever I tried to send GET request on that route, I would get "Cannot GET /xxx". I triple-checked everything and it looked fine, so I decided to make an exact copy of /hello route called /test, just changed some variables - doesn't work too, same error. Here is my /test route in swagger.yaml
/test:
# binds a127 app logic to a route
x-swagger-route-controller: test-route
get:
description: route for testing
# used as the method name of the controller
operationId: test
responses:
"200":
description: Success
schema:
# a pointer to a definition
$ref: "#/definitions/TestResponse"
# responses may fall trough to errors
default:
description: Error
schema:
$ref: "#/definitions/ErrorResponse"
and here is my test-route.js controller
'use strict';
module.exports = {
test
};
function test(req, res) {
res.json("Test Route");
}
As I said, it's almost exact copy of /hello default route, all other files in swagger project were untouched.
