I am using SFDX to develop an app for German users. My tests assume the test-running users has EURO as default currency. Therefore my tests fail as the admin user auto-created with a scratch org uses US dollars.
Is there any way I can modify this admin user?
I know that I can create additional scratch org users using
sfdx force:user:create --definitionfile config/user-def.json
but making one of those additional users the admin that logs in on force:org:open or runs tests seemed to be really complicated.
