Go - Testing

About

Go has a lightweight test framework composed of:

Example

Create a file myGoFile_test.go in the same directory that the file to test myGoFile

package main

import (
	"testing"
	"os"
	"path/filepath"
	"fmt"
)

func TestFileExist(t *testing.T) {

	const temp = "TEMP"
	tempDoesExist, _ := os.LookupEnv(temp);

	// Exist
	if _, err := os.Stat(tempDoesExist); err == nil {
		// path/to/file exists
		fmt.Printf("The path (%s) does exist", tempDoesExist)
	} else {
		t.Errorf("The path (%s) must exist", tempDoesExist)
	}

	// Doesn't exist
	tempDoesNotExist := filepath.Join(tempDoesExist, "1Er45pt")
	if _, err := os.Stat(tempDoesNotExist); os.IsNotExist(err) {
		// path/to/file does not exist
		fmt.Printf("The path (%s) does not exist", tempDoesNotExist)
	} else {
		t.Errorf("The path (%s) must not exist", tempDoesNotExist)
	}

}

Setup and TearDown

To add a setup and teardown method, just add the following code.

func TestMain(m *testing.Main) {
    setup()
    exitCode := m.Run()
    shutdown()
    os.Exit(exitCode)
}
