Blackbox testing using Arquillian

I am a QA person & do blackbox testing using Java + TestNG + Selenium WebDriver for our web application. I do not have access to the actual application code. My application runs on JBoss (in a remote server).

I heard about Arquillian recently & I saw some examples that they use Arquillian + WebDriver. When i googled, I could not get the exact use of Arquillian.

Questions:

• JUnit & TestNG are also unit testing frameworks. But I can use it for writing standalone blackbox testcases to test my application using WebDriver. Can this Arquillian also be used similarly?
• What features can it bring If i can use it in my existing TestNG framework? (for example, TestNG has parameter based testing, dependency support compared to JUnit).

Arquillian is NOT replacement for JUnit/TestNG, it is rather complementar - helps to manage lifecycle of the test and provides many useful extensions. In blackbox testing space, there are Graphene and Drone extensions.

I would encourage you to take a look at Graphene extension for Arquillian - these are focused on blackbox testing leveraging best practices such as Page Objects pattern:

Graphene also tightly connects to Drone extension for Arquillian that helps to configure WebDriver.

Both tools builds on top of WebDriver, they don't replace it.
