Answer 1

Years later this issue is still partly unsolved. There is a project by SB that can merge clover files, but it requires php 5.6.

None of the answers above work sufficiently well. Here is a gist of a merge thrown together. Constructive critisism welcome.

Usage:

php clover-merge.php -o merged.xml -f clover-phpunit.xml -f clover-phpspec.xml

Posting it here for posterity too:

project->asXML();
}

$fh = fopen($output ,'w');
if (! $fh) {
    echo "Cannot open '$output' for writing\n";
    exit(2);
}
fwrite($fh, sprintf('%s', $buffer));
fclose($fh);
