测试php函数的方法
本文提供的方法是用于测试php函数的代码,今天忽然想到的,就写了一段测试php函数的代码,代码如下:
- <?php
- /**
- * 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, $ParamList)
- {
- if(emptyempty($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" . $FunctionName . "<br />";
- foreach($TestParamList as $Key => $TestParamInfo)
- {
- echo "开始测试第" . $Key . "组参数:<br />";
- foreach($TestParamInfo as $ParamKey => $Param)
- {
- ${"Param" . $ParamKey} = $Param;
- $TempParamList[] = "$Param" . $ParamKey;
- if(is_array($Param))
- {
- echo "参数" . $ParamKey . ",类型为数组:";
- echo "<pre>";
- print_r($Param);
- }
- elseif(is_bool($Param))
- {
- echo "参数" . $ParamKey . ",类型为boll:";
- if($Param)
- {
- echo "true";
- }
- else
- {
- echo "false";
- }
- }
- else
- {
- echo "参数" . $ParamKey . ",类型为字符串或数字:";
- echo $Param;
- }
- echo "<br />";
- }
- $Params = join(", ", $TempParamList);
- unset($TempParamList);
- eval("$TestReturnResult = " . $FunctionName . "(" . $Params . ");");
- if(is_array($TestReturnResult))
- {
- echo "函数返回数组:<pre>";
- print_r($TestReturnResult);
- }
- elseif(is_bool($TestReturnResult))
- {
- if($TestReturnResult)
- {
- echo "函数返回true";
- }
- else
- {
- echo "函数返回false";
- }
- }
- else
- {
- echo "函数返回数字或字符串:" . $TestReturnResult;
- }
- echo "<br /><br />";
- }
- }
- /**
- * 计算组合的函数
- *
- * @param array $CombinList 待排列组合的2维数组
- * @return array 组合后的数组
- */
- function sysCombineArray($CombinList)
- {
- if(!is_array(current($CombinList)))
- {
- echo "参数不是2维数组";
- return false;
- }
- /* 计算C(a,1) * C(b, 1) * ... * C(n, 1)的值 */
- $CombineCount = 1;
- foreach($CombinList as $Key => $Value)
- {
- $CombineCount *= count($Value);
- }
- $RepeatTime = $CombineCount;
- foreach($CombinList as $ClassNo => $ParamList)
- {
- // $ParamList中的元素在拆分成组合后纵向出现的最大重复次数
- $RepeatTime = $RepeatTime / count($ParamList);
- $StartPosition = 1;
- foreach($ParamList as $Param)
- {
- $TempStartPosition = $StartPosition;
- $SpaceCount = $CombineCount / count($ParamList) / $RepeatTime;
- for($J = 1; $J <= $SpaceCount; $J ++)
- {
- for($I = 0; $I < $RepeatTime; $I ++)
- {
- $Result[$TempStartPosition + $I][$ClassNo] = $Param;
- } //phpfensi.com
- $TempStartPosition += $RepeatTime * count($ParamList);
- }
- $StartPosition += $RepeatTime;
- }
- }
- return $Result;
- }
- ?>
