在 Laravel Phpunit 下，在 Guzzle Promise 中调用 Illuminate config() 助手时会抛出 BindingResolutionException

Question

我在控制器内调用 Guzzle Promise 下的全局帮助函数 config() 时收到 BindingResolutionException()。

运行 phpunit 时，Guzzle Promise 下似乎没有加载 Illuminate helpers.php。是错误还是我误用了什么？

以下是我的代码。 （这是一个新的 Laravel 项目）

脚本

./vendor/phpunit/phpunit/phpunit tests/MyTest.php

例外

控制器

...
    public function index()

        $promise = new FulfilledPromise(null);
        $promise->then(function () {

        $response->assertStatus(200);

我最近遇到了这个问题，这是由于权限问题。 phpunit 需要对 .phpunit.result.cache 有写权限（至少）。
