Testing the code

Testing and benchmarking naturally belong to software development. Go, as a modern language with its built-in libraries, supports these from scratch. In this recipe, the basics of testing will be described.

How to do it...

1. Open the console and create the folder chapter11/recipe02.
2. Navigate to the directory.
3. Create the file sample_test.go with the following content:

        package main

        import (
          "strconv"
          "testing"
        )

        func TestSampleOne(t *testing.T) {
          expected := "11"
          result := strconv.Itoa(10)
          compare(expected, result, t)
        }

        func TestSampleTwo(t *testing.T) {
          expected := "11"
          result := strconv.Itoa(10)
          compareWithHelper(expected, result, t)
        }

        func TestSampleThree(t *testing.T) {
          expected := "10"
          result := strconv.Itoa(10)
          compare(expected, result, t)
        }

        func compareWithHelper(expected, result string...
