Summary

0001088: xdebug wont show dead and not executed lines at the 2nd time

Description

Here is a "test":

class TestMe
{
    public function test_ok()
    {
        $a = new TestMe2();
        $a->test_forgotToCall();
    }

    public function test_deadcode()
    {
        $a = 1;
        return;
        $a = 'this line wont be executed';
    }

    public function test_notExecuted()
    {
        $a = 'this line wont be executed';
    }
}

class TestMe2
{
    public function test_forgotToCall()
    {
        $a = 1; // I "accidentally" forget to call this at the 2nd test
    }

    public function test2()
    {
        $a = 1;
    }
}

xdebug_start_code_coverage (XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
$testObj = new TestMe();
$testObj->test_ok();
$testObj->test_deadcode();
//$testObj->test_notExecuted(); so not executed
var_dump (xdebug_get_code_coverage());
xdebug_stop_code_coverage();

xdebug_start_code_coverage (XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
$testObj = new TestMe2();
//$testObj->test_forgotToCall();
$testObj->test2();
var_dump (xdebug_get_code_coverage());
xdebug_stop_code_coverage();

the first test runs OK, but at the 2nd time, xdebug_get_code_coverage() just wont show the "unused" and "deadcode" lines, only the rans. If I pass false to xdebug_stop_code_coverage() then it does, but then the covered lines are "summed" so the fact that I forgot to test the test_forgotToCall() function will never turns our. (TestMe calls test_forgotToCall() so it will be covered. But TestMe2 doesnt call it, so test_forgotToCall() must be uncovered, but since TestMe had called it, it just wont turn out
