Laravel5.4上的示例PHPUnit测试失败,带有404

我可以通过link:localhost:8888/streaming_statistic/public在Laravel 5.4上创建我的项目

我有一个测试:

get('/');

        $response->assertStatus(200);
    }
}

我用命令运行所有测试

./vendor/bin/phpunit

但结果是:

PHPUnit 5.7.13 by Sebastian Bergmann and contributors.

F                                                                   1 / 1 (100%)

Time: 222 ms, Memory: 12.25MB

There was 1 failure:

1) Tests\Feature\ApiTest::testBasicTest
Expected status code 200 but received 404.
Failed asserting that false is true.

/Applications/MAMP/htdocs/streaming_statistic/tests/Feature/ApiTest.php:16

FAILURES!

我可以打开这个页面http:// localhost:8888/streaming_statistic/public / 我有一条路线:

Route::get('/', function () {
    return view('welcome');
});

我做错了什么？在laravel中为控制器方法编写测试的正确方法是什么？可能是HTTP测试它不是最好的解决方案吗？

对于测试这个env变量是错误的......

APP_URL=http://127.0.0.1:8888/streaming_statistic/public

我将root web服务器目录更改为streaming_statistic/public和env to

APP_URL=http://127.0.0.1:8888

之后我得到了:

OK (1 test, 1 assertion)
