• npm test
• set aliasEnabled to true
• npm start
• navigate to Send Token component, input an alias address (with .xec) that is registered onchain, then verify validation passes and parsed address is displayed in the console log. Send an eToken amount with this input and verify successful broadcast via explorer
• input a valid alias address (with .xec) that has yet to be registered onchain, then verify validation fails with the eCash Alias does not exist message displayed in the address input field UI.
• input foo.xec (already registered), then immediately change it to an invalid alias format and ensure it fails validation
• input foo.xec, then immediately change it to an unregistered alias format and ensure it fails validation
• ensure sending token via ecash address or etoken address has not regressed
• verify the placeholder text for the address input field shows Address or Alias
• set aliasEnabled to false and verify the placeholder text for the address input field only shows Address
• verify no alias cache updates on app load and no alias menu option
