Generate code coverage report outside of PHPUnit

coverage.php

<?php
xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);

// ...

$data = xdebug_get_code_coverage();
xdebug_stop_code_coverage();

$coverage = new PHP_CodeCoverage();
$coverage->append($data, 'some-id');

$report = new PHP_CodeCoverage_Report_HTML();
$report->process($coverage, '/tmp/coverage-report');

Instead of "$coverage->append($data, 'some-id');" when I put "$coverage->setData($data, 'some-id');" seems to be OK

EDIT: it produces 100% everywhere
