Não existe ambiente de teste na VTEX, mas você pode comprar outro ambiente para ser utilizado como teste
vc também pode criar outra loja dentro do seu ambiente e usa-lo como testes de front.
Mas, os dados de cadastro serão os mesmos.
Hello! We’re reviewing the most visited topics in our community and, for that reason, we’ve reopened your question so it can also help other store owners 
In this case, if the store is already in production and is IO, it’s possible to create a workspace/test environment. The documentation on VTEX IO is available at the following link: https://developers.vtex.com/vtex-developer-docs/docs/vtex-io-documentation-workspace. If the store is a legacy store, it’s not possible to create a workspace since any changes will be reflected on the front end, so the ideal solution is to hire a dedicated testing environment. This can be done through Support by selecting the Commercial option.
