测试php函数的方法_php实例

今天忽然想到的，就写了一段测试php函数的代码。

复制代码 代码如下:

/**
 * 参数数组$ParamList说明
 *
 * 数组的第一维索引是需要测试的函数的参数名，第二维的每个元素是该参数需要测试的可能值，元素值可以为数组。
 */
$ParamList = array("Param1" => array(3,4,3,2,1),
                   "Param2" => array(3,2,5),
                   "Param3" => array(0,0.5,1,1.5));
// 测试函数
sysTestFunction("Test", $ParamList);

// 待测试的函数
function Test($Param1, $Param2, $Param3)
{
    return $Param1 . "|" . $Param2 . "|" . $Param3;
}

/**
 * 自动测试
 *
 * @param  string  $FunctionName  函数名称
 * @param  array   $ParamList     参数列表
 * @return array
 */
function sysTestFunction($FunctionName, $ParamList)
{
    if(empty($FunctionName))
    {
        echo "函数名不能为空";
        return false;
    }
    if(!is_array(current($ParamList)))
    {
        echo "参数不是2维数组";
        return false;
    }
    $TestParamList = sysCombineArray($ParamList);
    echo "开始测试函数" . $FunctionName . "
";
    foreach($TestParamList as $Key => $TestParamInfo)
    {
        echo "开始测试第" . $Key . "组参数：
";
        foreach($TestParamInfo as $ParamKey => $Param)
        {
            ${"Param" . $ParamKey} = $Param;
            $TempParamList[] = "$Param" . $ParamKey;
            if(is_array($Param))
            {
                echo "参数" . $ParamKey . "，类型为数组：";
                echo "

";<br>                print_r($Param);<br>            }<br>            elseif(is_bool($Param))<br>            {<br>                echo "参数" . $ParamKey .
