Complete Automated / Integration Test

I'm an intern.

I have to do a COMPLETE test of integration for a catalog project. In your opinion, which is the best framework to perform this type of test?

Ps.: The project is in JAVA8 and JAVA7. You mean RESTfull. And the Gemfire connection database (apache Geode). JUnit 4

If you can give me framework tips thanks.

I'm in the appetizer 3: 1- Mockito 2 - Selenium 3 - Jmine
