Configuring testng+selenium project

How to configure TestNg Java maven project in CircleCI, I am new for this platform. Could anyone please share proper documentation with configuration steps. I am Mac user thanks

We have a documentation page for usage with maven that should give you a good start. or you can view our example project directly on GitHub.

Thanks I was able to run the tests . I have another issue now
So in my case Iā€™m first going to create a docker image of the web project and then use that web project to run my tests. Any idea on how I should go about it.
This is my config.yml now.
