php - 如果我在 SimpleTest 测试用例中使用函数的返回值，Apache 会崩溃

Question

当我在 simpletest 中运行以下测试用例时，如果我使用行 B，Apache 会崩溃，但如果我使用行 A，似乎一切正常。

class TestPredicateRequest extends UnitTestCase
{
    function testConstructWithPredicate()
    {
        Mock::generate("IQueryRequest");
        $oRequest = new MockIQueryRequest();

        $oPrototype = new QueryPrototype("TEST_COMMAND_STRING", 
                                         array(1 => QueryTypeConstants::CHARACTER_ID, 
                                               2 => QueryTypeConstants::CHARACTER_ID), 
                                         QueryTypeConstants::BOOLEAN);


        $oRequest->returns("GetArguments", array(2 => 102));  //only argument 2 is set.
        $oRequest->returns("GetPrototype", $oPrototype);
        $oRequest->returns("GetUnsetArguments", array(1)); //only argument 1 is unset

        $oToTest = new CharacterPredicateRequest($oRequest);

        $this->Here(101);                   //LINE A
        //$oItem = $this->Here(101);        //LINE B
    }

    function Here($CharacterID)
    {
        return $CharacterID;
    }
}

有什么可能的原因，是否存储函数的返回值是控制是否发生错误的原因？

附加信息:

如果我在 A 行或 B 行之后抛出异常，异常会冒泡到顶部，并且我会根据需要获得错误结果页面。这向我暗示，出于某种原因，SimpleTest 框架不喜欢 B 行的情况。是因为其中没有任何断言吗？

更新 x2:

Apache 的错误日志文件似乎毫无用处:

Answer 1

这可能是因为您对 B 的内存访问权限有限。在页面开头使用 set_ini() 到 -1 以使用无限资源。
