phpunit –debug still displays only dots

I want to see which test is currently executed during a phpunit run.

I use the --debug param but still only get dots:

$ phpunit --debug 
PHPUnit 3.7.19 by Sebastian Bergmann.

Configuration read from /home/foo/bar/phpunit.xml

..S.......I..

contents of phpunit.xml:

<phpunit backupGlobals="true"
     bootstrap="tests/bootstrap.php"
     backupStaticAttributes="false"
     cacheTokens="false"
     colors="true"
     convertErrorsToExceptions="true"
     convertNoticesToExceptions="true"
     convertWarningsToExceptions="true"
     forceCoversAnnotation="false"
     mapTestClassNameToCoveredClassName="false"
     printerClass="PHPUnit_TextUI_ResultPrinter"
     processIsolation="false"
     stopOnError="false"
     stopOnFailure="false"
     stopOnIncomplete="false"
     stopOnSkipped="false"
     testSuiteLoaderClass="PHPUnit_Runner_StandardTestSuiteLoader"
     strict="false"
     verbose="true">
    <testsuites>
    <testsuite name="foo Tests">
        <directory>./tests</directory>
    </testsuite>
    </testsuites>
    <filter>
    <whitelist addUncoveredFilesFromWhitelist="true">
        <directory suffix=".php">./src</directory>
    </whitelist>
    </filter>
    <logging>
    <log type="coverage-clover" target="./clover.xml"/>
    </logging>
</phpunit>

What can be the reason for this?

Answer

I had the same problem and resolved it by removing this:

printerClass="PHPUnit_TextUI_ResultPrinter"

from the options on the base tag in the phpunit.xml config file.
