How to share your Gitpod workspace

In the top right corner of your running workspace, you will see your avatar. By clicking on your avatar, you will open the following dropdown.

After clicking on the “Share Running Workspace” option, the following pop up will appear. To share your workspace, click the “Share” button and then provide the person you are sharing with the displayed URL. It is important to note that only the workspace owner can start up the workspace. This means that if the workspace is not running, whoever has the share link will not be able to view the workspace.

I'm trying to write tests for a gem that is mounted in a Rails app. It's similar to a Rails Engine, except it's a Sinatra app that is mounted alongside the Rails app using the Rack Builder method.

I've configured config.ru like so

require_relative 'config/environment'

map '/git' do
  run WebGit::Server
end

| | * bc9833b (HEAD -> b-branch) Another space
| |/
