Hi! Trying to launch my first tests.
Cant understand what value will be injected in test parameter - @ArquillianResource URL base ?
It must be specified in some xml file ?
Can you explain? My test1 with such parameter is skipped because no parameter provided:

test1
org.testng.TestNGException:
Method test1 requires 1 parameters but 0 were supplied in the @test annotation.
