phpunit assertRegExp() 测试在 unix 中通过，在 windows 中失败

Question

我有一个 PHPUnit 测试，它使用正则表达式验证日志文件的输出。日志文件看起来像这样(第一行是空的，但我不知道如何在这里显示):

<empty line>

我正在使用正则表达式验证内容:

    $strExpectedMeasurementLog = "#

$strActualMeasurementLog = file_get_contents( dirname( __FILE__)."/applogs/measurement.log");
self::assertRegExp( $strExpectedMeasurementLog, $strActualMeasurementLog);

PHPUnit 测试是在 unix 环境中创建的。本次测试在unix测试环境下通过，但在windows测试环境下失败。我通过将此函数应用于 measurement.log 文件，将 windows 换行符替换为 unix 换行符:

public function unixtodos( $strPathFile )
{
  $strCurrent = file_get_contents( $strPathFile );

  $strPattern = "|\r\n|";
  $strReplace = "\n";
  $strNew = preg_replace( $strPattern, $strReplace, $strCurrent );

  file_put_contents( $strPathFile, $strNew );
}

它仍然不匹配，我没有想法:(

解决方案是始终检查换行符。我在 windows 机器上用 php 创建的日志文件有 unix 换行符:

在unix中从CVS check out 的PHPUnit源文件有unix换行符:

windows中CVS check out 的PHPUnit源文件有windows换行符:

这些换行符破坏了我的正则表达式验证。所以现在我总是将换行符替换为 unix 换行符。

// replace possible windows line breaks with unix line breaks
$strExpectedMeasurementLog = preg_replace( "|\r\n|", "\n", $strExpectedMeasurementLog);
$strActualMeasurementLog = preg_replace( "|\r\n|", "\n", $strActualMeasurementLog);
