Question

I have a PHPUnit Test which validates the output of a logfile with a regexp. The logfile looks like this(First line is empty, but I don’t know how to display that here):

<empty line>

I am validating the content with a regex:

    $strExpectedMeasurementLog = "#

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

The PHPUnit test was created in a unix environment. This test passes in a unix test environment, but fails in a windows test environment. I have replaced windows line breaks with unix line breaks by appyling this function to the measurement.log file:

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 );
}

It still doesn’t match and I am out of ideas 🙁

Answer 1

The solution is to always check the line breaks. My logfile created on a windows machine with php has unix line breaks:

The PHPUnit source file checked out of CVS in unix has unix line breaks:

The PHPUnit source file checkout out of CVS in windows has windows line breaks:

These line breaks broke my regex validation. So now I’m always replacing line breaks to unix line breaks.

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