For example, there is a simple function:

func add(x, y int) int { return x + y }

What are the built-in tools that allow it to test?

    There is a gotest command. For the sample package, running the gotest command will return a PASS test.

    Sample.go file:

     package sample func Add(x, y int) int { return x + y }

    Sample_test.go file:

     package sample import "testing" func TestAdd(t *testing.T) { var x, y, z int = 1, 2, 3 if z != Add(x, y) { t.Errorf("%d != %d", z, x + y) } }

    Makefile:

     include $(GOROOT)/src/Make.inc TARG=sample GOFILES=sample.go include $(GOROOT)/src/Make.pkg
