Strange Issue with `selectRaw` and `with` during Testing with SQLite

Hello everyone,

I've encountered a strange issue in my Laravel project and could really use some help. I have the following method in my Statement model:

public function territoryRevenues()
{
    return $this->revenues()
        ->selectRaw("
            'App\\\\Territory' as source_type,
            series.territory_id as id,
            series.territory_id as source_id,
            SUM(revenue_total) as revenue_total
        ")
        ->join('series', 'revenues.source_id', '=', 'series.id')
        ->groupBy('series.territory_id')
        ->with(['source' => function ($query) {
                $query->withTrashed();
        }]);
}

This method works perfectly in production and returns the desired results without any intermediate SQL queries. However, I've been encountering a weird issue when running PHPUnit tests that use this specific method.

The error message I receive is: "Cannot declare class App\Territory, because the name is already in use". After some digging, I realized that this issue only arises when using SQLite, which is why it only occurs during testing. It seems that the combination of selectRaw and with is causing the problem. When I remove the with statement, the issue disappears. Even replacing it with a simple ->with('source') triggers the same error.

I'd really like to be able to test this code. Has anyone else encountered a similar issue or have any insights into why this might be happening? Any help or suggestions would be greatly appreciated!

Thanks in advance!

The issue you're encountering is likely due to the way SQLite handles certain SQL operations differently compared to other databases like MySQL or PostgreSQL. Specifically, the combination of selectRaw and with might be causing SQLite to misinterpret or mishandle the query, leading to the "Cannot declare class" error.

Here are a few steps you can take to troubleshoot and potentially resolve this issue:

Check for Namespace Conflicts: Ensure that there are no namespace conflicts or duplicate class declarations in your codebase. This error can sometimes be caused by autoloading issues or duplicate class names.
Simplify the Query for Testing: Since the issue only occurs during testing with SQLite, you can try simplifying the query to isolate the problem. For example, you can remove the selectRaw part and see if the issue persists.
Use Eloquent Relationships: Instead of using selectRaw, you can try to achieve the same result using Eloquent relationships and query builder methods. This might help SQLite handle the query better.
Custom Testing Database Configuration: Consider using a different database for testing that is more similar to your production environment. This can help avoid SQLite-specific issues.

Here's a modified version of your method that avoids using selectRaw and instead uses Eloquent relationships and query builder methods:

public function territoryRevenues()
{
    return $this->revenues()
        ->join('series', 'revenues.source_id', '=', 'series.id')
        ->select([
            DB::raw("'App\\\\Territory' as source_type"),
            'series.territory_id as id',
            'series.territory_id as source_id',
            DB::raw('SUM(revenue_total) as revenue_total')
        ])
        ->groupBy('series.territory_id')
        ->with(['source' => function ($query) {
            $query->withTrashed();
        }]);
}

If the above solution still doesn't work, you can try breaking down the query into smaller parts and testing each part individually to identify the exact cause of the issue.

Additionally, you can create a custom testing database configuration in your phpunit.xml file to use a different database for testing:

<php>
    <env name="DB_CONNECTION" value="mysql"/>
    <env name="DB_DATABASE" value="test_database"/>
    <env name="DB_USERNAME" value="root"/>
    <env name="DB_PASSWORD" value=""/>
</php>

This way, you can avoid SQLite-specific issues and ensure that your tests run in an environment similar to production.

I hope this helps! Let me know if you have any further questions or need additional assistance.
