Laravel Unit Test Class Not Found

<?php 
use App'Repositories'APIModels'SalesError as SalesError;
use App'Repositories'APIModels'Sales as Sales;
class SalesErrorTest extends 'TestCase {
    public function setUp()
    {
        parent::setUp();
    }
    public function testCreate()
    {
        $sales_error = new SalesError;
        $sales_error->sale_id = 5;
        $sales_error->error_type = 3;
        $sales_error->description = 'Unknown error occured';
        $sales_error->resolved_at = date('Y-m-d H:i:s');
        $this->assertTrue($sales_error->save());
    }
    public function testRelation()
    {
        $sales = Sales::find(45)->errors();
        var_dump($sales);
    }
}

在上面的测试中，当我运行testCreate它工作正常。但是当我运行其他方法时，它说

PHP 致命错误：在中找不到类"销售错误" /vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php 在 878 行

销售模式

   /**
     * Has Many relation with SalesError
     * 
     * @return object
     */
    public function errors()
    {
        return $this->hasMany('SalesError', 'sale_id', 'sale_id');
    }

销售错误模型

  /**
     * Has many to one relation with Sales Model
     * 
     * @return void
     */
    public function sales()
    {
        $this->belongsTo('Sales', 'sale_id');
    }

您应该将完整的namespace传递给关系。

此外，您在sales关系中缺少return语句。

public function errors()
{
    return $this->hasMany('App'Repositories'APIModels'SalesError', 'sale_id', 'sale_id');
    // or
    return $this->hasMany(SalesError::class, 'sale_id', 'sale_id');
}
public function sales()
{
    return $this->belongsTo(Sales::class, 'sale_id');
}
