This fork its updated to PHP8.0.

PHP utility to merge two or more clover files into a single document.

Intended to be used in a build pipeline to merge clover output from multiple testing frameworks.

I spent a weekend writing this so you don't have to.

$ composer require kavinsky/clover-merge

$ ./vendor/bin/clover-merge merge -o combined.xml input1.xml input2.xml
Files Discovered: 332
Final Coverage: 14534/14558 (99.84%)
