## 測試用例

### 設計模式

運行腳本： php patterns/[文件夾名稱]/test.php

```
例如,

測試責任鏈模式： 運行 php patterns/chainOfResponsibility/test.php

運行結果：

請求5850c8354b298: 令牌校驗通過～
請求5850c8354b298: 請求頻率校驗通過～
請求5850c8354b298: 參數校驗通過～
請求5850c8354b298: 簽名校驗通過～
請求5850c8354b298: 權限校驗通過～
```

### 算法

運行腳本： php algorithm/test.php [算法名稱｜空獲取列表]

```
例如,

測試冒泡排序： 運行 php algorithm/test.php　bubble

運行結果：

==========================冒泡排序=========================
Array
(
    [0] => 11
    [1] => 67
    [2] => 3
    [3] => 121
    [4] => 71
    [5] => 6
    [6] => 100
    [7] => 45
    [8] => 2
)
=========上為初始值==================下為排序后值=============
Array
(
    [0] => 2
    [1] => 3
    [2] => 6
    [3] => 11
    [4] => 45
    [5] => 67
    [6] => 71
    [7] => 100
    [8] => 121
)
```

### 常見redis運用實現

運行腳本： php redis/test.php [名稱｜空獲取列表]

```
例如,

測試悲觀鎖： 運行 php redis/test.php p-lock

運行結果：

執行count加1操作～

count值為：1

```
