    More details

    Adding source code

    1. Click on Add source
    2. Choose source control
      • Github
        • Click on Connect
        • Authorize O-Auth
        • Fill Repository Owner
        • Click Repository and choose from the dropdown menu
        • Click Next
        • Choose the desired branch
        • Click View Repository
      • Local FileSystem - Server
        • Click on Setup Server
        • Choose a supported HTTP Server
        • Follow the on-screen instructions

  • Open the file app.py

  • Add a Snapshot Breakpoint next to line number 74 by clicking next the the line number in the file viewer

  • Looking at the right-hand pane Breakpoints, you will see the Breakpoint you added, on what line you added it and it should be GREEN, meaning everything is communicating correctly.

    • If this is not the case, click here to see how to fix that
  • Go the the app webpage http://localhost:5000/ and add a todo in order to trigger the Breakpoint

  • Check the bottom pane Messages and you'll see the snapshot you just added, as it was triggered by the handler of the web api when you added a todo

Go through the bug list and follow instructions to see some basic use cases.

Common Pitfalls

  • Breakpoint status is RED -- Hash mismatch. It means the file used in the server is not the same file used from github/local server in app.rookout.com
  • Breakpoint status is GRAY -- No app connected. Make sure you have inserted the Rookout Token in the right place and that connection is made properly.
