Running tests in addInt_test.go

Let's now run the tests in this file, and we are expecting each of the row in the testCases table, which we ran, to be treated as a separate test:

$ go test -v ./{addInt.go,addInt_test.go}                           
=== RUN   TestAddInt                       
=== RUN   TestAddInt/addInt()_->_0         
=== RUN   TestAddInt/addInt([]int{10,_20,_100})_->_130                                
--- PASS: TestAddInt (0.00s)

        addInt_test.go:23: 0 == 0
