How to test the equivalence of maps in Golang?

Question

I have a table-driven test case like this one:

func CountWords(s string) map[string]int

func TestCountWords(t *testing.T) {
  var tests = []struct {
    input s         


        

Answer 1

Simplest way:

    assert.InDeltaMapValues(t, got, want, 0.0, "Word count wrong. Got %v, want %v", got, want)

Example:

import (
    "github.com/stretchr/testify/assert"
    "testing"
)

func TestCountWords(t *testing.T) {
    got := CountWords("hola hola que tal")

    want := map[string]int{
        "hola": 2,
        "que": 1,
        "tal": 1,
    }

    assert.InDeltaMapValues(t, got, want, 0.0, "Word count wrong. Got %v, want %v", got, want)
}
