You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: generic_test.go
    path of file: ./repos/kit/metrics/generic
    
    the code of the file until where you have to start completion: package generic_test

// This is package generic_test in order to get around an import cycle: this
// packa
    
func TestAtomicAlignment(t *testing.T) {
	content, err := ioutil.ReadFile("./generic.go")
	if err != nil {
		t.Fatal(err)
	}

	fset := token.NewFileSet()

	file, err := parser.ParseFile(fset, "generic.go", content, parser.ParseComments)
	if err != nil {
		t.Fatal(err)
	}

	conf := types.Config{Importer: importer.ForCompiler(fset, "source", nil)}

	pkg, err := conf.Check(".", fset, []*ast.File{file}, nil)
	if err != nil {
		t.Fatal(err)
	}

	// uses ARM as reference for 32-bit arch
	sizes := types.SizesFor("gc", "arm")

	names := []string{"Counter", "Gauge"}

	for _, name := range names {
		t.Run(name, func(t *testing.T) {
			checkAtomicAlignment(t, sizes, pkg.Scope().Lookup(name), pkg)
		})
	}
}
