Use the "--coverage-php
" option to PHPUnit to get it to write the coverage data as a serialized PHP_CodeCoverage
object, then combine them using PHP_CodeCoverage::merge
, like this:
<?php
/**
* Deserializes PHP_CodeCoverage objects from the files passed on the command line,
* combines them into a single coverage object and creates an HTML report of the
* combined coverage.
*/
if ($argc <= 2) {
die("Usage: php generate-coverage-report.php cov-file1 cov-file2 ...");
}
// Init the Composer autoloader
require realpath(dirname(__FILE__)) . '/../vendor/autoload.php';
foreach (array_slice($argv, 1) as $filename) {
// See PHP_CodeCoverage_Report_PHP::process
// @var PHP_CodeCoverage
$cov = unserialize(file_get_contents($filename));
if (isset($codeCoverage)) {
$codeCoverage->filter()->addFilesToWhitelist($cov->filter()->getWhitelist());
$codeCoverage->merge($cov);
} else {
$codeCoverage = $cov;
}
}
print "
Generating code coverage report in HTML format ...";
// Based on PHPUnit_TextUI_TestRunner::doRun
$writer = new PHP_CodeCoverage_Report_HTML(
'UTF-8',
false, // 'reportHighlight'
35, // 'reportLowUpperBound'
70, // 'reportHighLowerBound'
sprintf(
' and <a href="http://phpunit.de/">PHPUnit %s</a>',
PHPUnit_Runner_Version::id()
)
);
$writer->process($codeCoverage, 'coverage');
print " done
";
print "See coverage/index.html
";
You may also be able to merge the files using a tool named phpcov
, as described here: https://github.com/sebastianbergmann/phpunit/pull/685
