Testing Instructions

Setup

• Find and edit the HydroShare OAuth MMW Beta entry in LastPass
• Copy the value of client-secret, qxt...oj5
• Use it to initialize the variable in the app VM:

  vagrant ssh app -c 'echo qxt...oj5 | sudo tee /etc/mmw.d/env/MMW_HYDROSHARE_SECRET_KEY'
  vagrant ssh app -c 'sudo service mmw-app restart'

Testing

• Check out this branch
• Run the JavaScript bundler:

  ./scripts/bundle.sh --debug

• Reload Celery to pick up changed tasks:

  vagrant ssh worker -c 'sudo service celeryd restart'

• Go to http://localhost:8000/ and log in as a user
• Select an area of interest and get to the modeling stage (doesn't matter which model)
• Click Share to open the Share Menu:
  
• In the Share Menu, turn on HydroShare Export:
  
  • Ensure you see the Link Account to HydroShare modal:
    
• Follow the instructions to link your account:
  
• Use credentials from LastPass for HydroShare OAuth MMW Beta:
  
  • Ensure you are redirected to MMW correctly
• Go back to your saved project, and try exporting to HydroShare again. This will take a few minutes.
  
  • Ensure it succeeds
• Click the link to open the project in HydroShare:
  
  
• Copy the resource ID from the URL. In my case, it is b8e1c3315bfa461abac3db5e7e180766. Replace the ID with yours in the next tests:
• Navigate to http://localhost:8000/project/via/hydroshare/b8e1c3315bfa461abac3db5e7e180766/
  • Ensure it succeeds
• Navigate to http://localhost:8000/project/via/hydroshare/b8e1c3315bfa461abac3db5e7e180766/edit/
  • Ensure it succeeds
• Log out from MMW
• Navigate to http://localhost:8000/project/via/hydroshare/b8e1c3315bfa461abac3db5e7e180766/
  • Ensure it succeeds
• Navigate to http://localhost:8000/project/via/hydroshare/b8e1c3315bfa461abac3db5e7e180766/edit/
  • Ensure you are prompted to log in, ensuring that only project owners are allowed to edit the project
