How to test 🧪

Prerequisites

(How to setup test environment)

• Checkout this PR and point to devcloud locally
• Have a Postgres Database cluster with at least one connection pool (add via Networking tab)

Reproduction steps

(How to reproduce the issue, if applicable)

• Go to a Postgres cluster's details summary page. You should see a general service URI and a postgres service URI field
• Click reveal password on one of them. Notice that the loading states for both are sync'd
• Refresh and click on Show next to the password field. Notice that the loading state is also sync'd with the service URI fields
• Refresh and block the credentials network request call
• Click on reveal password or show. The error states are also sync'd
• Suspend the cluster
• The click to reveal password button is not disabled
• Edit connection pool menu action in the Networking tab is not disabled

Verification steps

(How to verify changes)

• Go to a Postgres cluster's details summary page. You should see a general service URI and a postgres service URI field
• Click reveal password on one of them. Only the selected field should display a loading state
• Refresh and click on Show next to the password field. Only the password loading state should display. Service URI loading states should not display
• Refresh and block the credentials network request call
• Click on reveal password or show. Only the selected field should display a loading state, and you should see an error toast instead of the retry button
• Suspend the cluster
• The click to reveal password button is disabled
• Edit connection pool menu action in the Networking tab is disabled
