RedisClient
var ctx = context.TODO()
func NewsInfoForCache(redisDB *redis.Client, newsID int) (info string, err error) {
cacheKey := fmt.Sprintf("news_redis_cache_%d", newsID)
info, err = redisDB.Get(ctx, cacheKey).Result()
if err == redis.Nil {
// info, err = call api()
info = "test"
err = redisDB.Set(ctx, cacheKey, info, 30 * time.Minute).Err()
}
return
}
func TestNewsInfoForCache(t *testing.T) {
db, mock := redismock.NewClientMock()
newsID := 123456789
key := fmt.Sprintf("news_redis_cache_%d", newsID)
// mock ignoring `call api()`
mock.ExpectGet(key).RedisNil()
mock.Regexp().ExpectSet(key, `[a-z]+`, 30 * time.Minute).SetErr(errors.New("FAIL"))
_, err := NewsInfoForCache(db, newsID)
if err == nil || err.Error() != "FAIL" {
t.Error("wrong error")
}
if err := mock.ExpectationsWereMet(); err != nil {
t.Error(err)
}
}
