Compare a list of strings/GoTests

The Go test tool can help validate code as an alternative to writing a complete program and providing output. The task is coded as a Go package. Code here would be named something like test_cmp.go and exist in the same directory as the task code.

<lang go>package cmp_test

import (

   "testing"

   "cmp"

)

var eqTests = []struct {

   desc string
   list []string
   want bool

}{

   {
       "just one string",
       []string{"a"},
       true,
   },
   {
       "2 equal",
       []string{"a", "a"},
       true,
   },
   {
       "2 unequal",
       []string{"a", "b"},
       false,
   },

}

var ltTests = []struct {

   desc string
   list []string
   want bool

}{

   {
       "just one string",
       []string{"a"},
       true,
   },
   {
       "2 ordered",
       []string{"a", "b"},
       true,
   }, 
   {
       "2 not strictly ordered",
       []string{"a", "a"},
       false,
   },

}

func TestAllEqual(t *testing.T) {

   for _, tc := range eqTests {
       if got := cmp.AllEqual(tc.list); got != tc.want {
           t.Errorf("%s: want %t, got %t", tc.desc, tc.want, got)
       }
   }

}

func TestLessThan(t *testing.T) {

   for _, tc := range ltTests {
       if got := cmp.AllLessThan(tc.list); got != tc.want {
           t.Errorf("%s: want %t, got %t", tc.desc, tc.want, got)
       }
   }

}</lang>

Example test:

$ go test -coverprofile p
PASS
coverage: 100.0% of statements
ok  	cmp	0.004s
