Testing instructions

You won't be able to access the new views through the UI, but you can get there by going directly to the routes:

• /forms/{form_id}/make-live/en
  • your form will need to:
    • be ready to be made live
    • not have a live or archived English version
    • not have a live welsh version
• /forms/{form_id}/make-live/cy
  • your form will need to:
    • be ready to be made live
    • have a live English version
    • not have a live welsh version

Things to consider when reviewing

• Ensure that you consider the wider context.
• Does it work when run on your machine?
• Is it clear what the code is doing?
• Do the commit messages explain why the changes were made?
• Are there all the unit tests needed?
• Do the end to end tests need updating before these changes will pass?
• Has all relevant documentation been updated?
