Erro ao conectar SQuirreL SQL Client

Pessoal, boa tarde! sou nova no fórum e espero conseguir ajuda para um erro de conexão usando o SQuirreL SQL Client.
Fiz a instalação do SQuirreL SQL Client e do driver MySQL porem quando tento conectar retorna o seguinte erro:

O acesso está normal no Workbench porem tenho preferencia pelo SQuirreL .

Se eu tiver postado no local errado, aguardo orientações

Qual é o url que estás a colocar no squirrel?

pmlm

jdbc: mysql: //127.0.0.1: 3306 /test

estou deixando o print da configuração do squirrel

Falta o nome da base de dados depois da porta. No print não tens o /test

pmlm obrigada pela ajuda, na verdade não tinha criado o database, pelo Workbench consegui fazer o teste de conexão mesmo sem nenhum BD. O Squirell deve ter uma configuração diferente, criei o database e consegui conectar.
