问题 I run an project on Sinatra, now it has a lot of files a sub-directories, so I want to view a list of those files with their respective directory. For example, I put in the address bar "localhost:4567/landing/" where landing is the container of some pages, but it throw me this "Sinatra doesn’t know this ditty." Is there a way to do that.

Can I test that a Sinatra post method successfully saves to a YAML store?

For self-study, I'm building a "to do" app in Ruby/Sinatra and I'm trying to use TDD everything and unit test like a good little boy. A requirement I have is: When a user posts a new task, it is saved in
