解析 clover 覆盖率

[sinkcup]

PHPUnit、jest 都可以生成 clover xml

<coverage generated="1636543368">
<project timestamp="1636543368">
<file name="api-php/app/Console/Kernel.php">
...
</file>
<metrics files="36" loc="1328" ncloc="772" classes="25" methods="38" coveredmethods="21" conditionals="0" coveredconditionals="0"
 statements="97"
 coveredstatements="54"
 elements="135" coveredelements="75"/>
</project>
</coverage>

对比 PHPUnit text 格式可知：行覆盖率是 coveredstatements / statements

发现一个坑：clover xml 没有直接汇总 class 覆盖率，而是要根据 <file /> 计算，很麻烦，这个需求不重要，暂时不做。
