[verb]Json() methods in tests are not obeying the config('app.url') after upgrading to 7.x

[tanmaymishu]

I have upgraded the laravel version to 7.17.2 from 6.16.0 a few minutes ago following the upgrade guide.

But my tests are now failing with the following exception: Symfony\Component\HttpKernel\Exception\NotFoundHttpException : POST http://localhost/v1/orders

The APP_URL is set to http://localhost in my .env file. But in my base TestCase class, I am overriding the config('app.url') with a custom endpoint. Before the upgrade, the tests were picking the custom endpoint.

Since the last upgrade, apparently the getJson(), postJson(), etc helper methods are not applying the URL from config('app.url') but directly from the .env file. Because when I hardcode the URL in the .env file, I no longer get the NotFoundHttpException.

Is this behavior expected? If so, how does one overcome it?

The problem also occurs when updated to v6.18.22 from v6.16.0

Something changed between these two versions.

I am using URL::forceRootUrl() to solve this for the time being.

protected function setUp(): void
{
    parent::setUp();

    URL::forceRootUrl('http://base-api.' . config('others.appHost'))
}
