I'm trying to make this test suite pass through the command prompt (hello-world\_test.go):

```
package helloworld

import "testing"

func TestHelloWorld(t *testing.T) {
    output := sayHello()
    if "Hello, World!" != output {
        t.Fatalf("output: %s\nexpected: Hello,World!", output)
    }
}

```

my code is as follows (helloworld.go):

```
package helloworld

import "fmt"

func sayHello() {
    fmt.Println("Hello, World!")

}

```

and the error code through the command prompt is: 

```
C:\Users\Troy\exercism\go\hello-world\go test -v
# _/C_/Users/Troy/exercism/go/hello-world
.\hello-world_test.go:6: sayHello() used as value
FAIL    _/C_/Users/Troy/exercism/go/hello-world [build failed]

```
