Test Scenarios

Scenario 1 - Validate the "tada" icon is not visible while syncing

Given that Daedalus is syncing
And the syncing progress has reached the Alonzo era epoch
When I check the top bar
Then I can see that no "tada" icon is displayed

Scenario 2 - Validate the "tada" is not visible when Daedalus is synced

Given that Daedalus is synced
When I check the top bar
Then I can see that no "tada" icon is displayed
And on "Staking center" the "info" tab is no longer visible

Note: Use daedalus.api.ada.getNetworkParameters() to get the starting epochs for all the eras.
