Goでテスト

標準パッケージのtestingを用いたテストの書き方についてみていきます。

テスト対象は先日作成した多層キャッシュプログラムです。

テスト対象↓

adapters/redis_adapter.go
package adapters

import "github.com/go-redis/redis"


type  RedisAdapter struct {
	client *redis.Client
}

func NewRedisAdapter() *RedisAdapter {
	return &RedisAdapter{
		client: redis.NewClient(&redis.Options{
			Addr:     "localhost:6381",
			Password: "",
			DB:       0,
		}),
	}
}

func (adapter *RedisAdapter) Get(key string) string {
	val, err := adapter.client.Get(key).Result()
	if err != nil {
		return ""
	}
	return val
}

func (adapter * RedisAdapter) Set(key string, value string) {
	adapter.client.Set(key, value, 0)
}

func (adapter * RedisAdapter) Delete(key string) {
	adapter.client.Del(key)
}j

命名規則としてファイル名の末尾は_test.goである必要があります。

touch adapters/redis_adapter_test.go

関数名の命名規則はTestから始まる必要があります。

adapters/redis_adapter_test.go
package adapters

import (
	"testing"
)

func TestRedisAdapter_Get(t *testing.T) {
	adapter := NewRedisAdapter()

	adapter.Set("key", "value")
	want := "value"
	got := adapter.Get("key")

	if got != want {
		t.Error("失敗")
	}
}

testingassert関数は無いため、期待と実際が異なった際に、
t.Error("失敗")にしています。

テスト実行

 go test ./adapters

ok  	in_memory_cache_demo/adapters	0.286s
shuyafukushima@Shuya:~/programing/in_memory_cache_demo

-vオプションをつけることでより詳細な出力を得ることができます。

go test -v ./adapters
=== RUN   TestRedisAdapter_Get
--- PASS: TestRedisAdapter_Get (0.02s)
PASS
ok  	in_memory_cache_demo/adapters	0.124s
