Hi! Is there some way in Ktor to use the the normal application.conf in testing but overwrite only some of the properties? I want my application to fail if credentials are not provided, but want to provide some dummy values during testing.

twitter {
    apiKey = ${TWITTER_API_KEY}
    apiSecretKey = ${TWITTER_API_SECRET_KEY}
    accessToken = ${TWITTER_ACCESS_TOKEN}
    accessTokenSecret = ${TWITTER_ACCESS_TOKEN_SECRET}
}

P.S.: Found some hints here

This answer may help you.

Thank you!
