## 测试用例

### 设计模式

运行脚本： php patterns/[文件夹名称]/test.php

```

例如,

测试责任链模式： 运行 php patterns/chainOfResponsibility/test.php

运行结果：

请求5850c8354b298: 令牌校验通过～

请求5850c8354b298: 请求频率校验通过～

请求5850c8354b298: 参数校验通过～

请求5850c8354b298: 签名校验通过～

请求5850c8354b298: 权限校验通过～

```

### 算法

运行脚本： php algorithm/test.php [算法名称｜空获取列表]

```

例如,

测试冒泡排序： 运行 php algorithm/test.php　bubble

运行结果：

==========================冒泡排序=========================

Array

(

[0] => 11

[1] => 67

[2] => 3

[3] => 121

[4] => 71

[5] => 6

[6] => 100

[7] => 45

[8] => 2

)

=========上为初始值==================下为排序后值=============

Array

(

[0] => 2

[1] => 3

[2] => 6

[3] => 11

[4] => 45

[5] => 67

[6] => 71

[7] => 100

[8] => 121

)

```

### 常见redis运用实现

运行脚本： php redis/test.php [名称｜空获取列表]

```

例如,

测试悲观锁： 运行 php redis/test.php p-lock

运行结果：

执行count加1操作～

count值为：1

```
