使用PHPUnit和XDebug在Generators中提前退出的PHP代码覆盖率

Question

I'm not sure if this is a bug, but I don't seem to be able to get 100% coverage with early exit inside a PHP 5.5 generator.

For example:

<?php

function gen($branch = false)
{
    yield;

    if($branch) {
        echo 'branched';
        return;
    } // This line is never covered.
    echo 'did not branch';

}

The closing bracket of the if statement is never covered. It's not considered "dead code", it behaves as though you didn't consider the possibility of exiting the if statement.

I don't want to use an else because, as phpmd would say, "else is never necessary", but I would like to get 100% coverage (as that makes it easy to see if I've missed something in new code without drilling down).

Has anyone else run into this? Is there a solution?

这是Xdebug中的错误，在2.4.0版中已解决
