require_once 'vendor/autoload.php';

// We neeed WordPress Bootstrap files for its test.

define('WP_TEST_DIR', parse_ini_file('test-config.ini')['test-location']);

// Include the bootstrap file.
require_once WP_TEST_DIR . 'includes/bootstrap.php';

// Include the Functions file
require_once WP_TEST_DIR . 'includes/functions.php';

当我在日志部分未注释的情况下运行它时，我得到:

当我注释掉日志记录时，我得到:

OK (34 tests, 38 assertions)

为什么它会在没有可见错误的情况下死掉？这是内存问题吗？如果是这样，为什么不那样说呢？这些测试集确实包括 WordPress 测试套件类 WP_UnitTestCase 以允许我为一些测试设置一个假的 Wordpress 安装但是正如你所看到的，我第二次运行测试时日志记录被注释out 我使用了 45.50mb 内存。没什么。

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
display_errors = On
display_startup_errors = Off

PHP 版本为 5.5.9

这是怎么回事？ (是的，覆盖文件夹存在)

在这种情况下，我需要增加 PHP 的内存吗？

最佳答案

我发现在 PHPUnit 中诊断 fatal error 的最佳(唯一？)方法是在 Bootstrap 中添加一个关闭错误陷阱。 PHPUnit 自身会捕获错误以帮助报告，但出于某种原因，这会完全阻止报告某些核心/致命类型错误。

我将其添加到我的所有项目中:

phpunit.xml:

< phpunit
    bootstrap="bootstrap.php"
...

bootstrap.php:

// PHPUnit dies silently with FATAL ERRORS which makes it hard to debug the tests.
register_shutdown_function('PHPUnit_shutdownFunction');
function PHPUnit_shutdownFunction() {
    // http://www.php.net/manual/en/errorfunc.constants.php
    $error = error_get_last();
    if (!is_null($error)){
        if($error['type'] & (E_ERROR + E_PARSE + E_CORE_ERROR + E_COMPILE_ERROR + E_USER_ERROR + E_RECOVERABLE_ERROR)){
            echo 'Test Bootstrap: Caught untrapped fatal error: ';
            var_export($error);
        }
    }
}

这些神秘的问题将成为过去。
