从结论开始,我得到这个错误:

[ErrorException]                                                                                                                                                                                    
Argument 1 passed to SomeValidatorTest::__construct() must be an instance of App\Services\Validators\SomeValidator, none given, called in ....vendor/phpunit/phpunit/src/Framework/TestSuite.php on line 475 and defined  

在Laravel应用程序中,我有一个名为"SomeValidator.php"的脚本,如下所示:

<?php namespace App\Services\Validators;

use App\Services\SomeDependency;

class SomeValidator implements ValidatorInterface
{

    public function __construct(SomeDependency $someDependency)
    {
        $this->dependency = $someDependency;
    }

    public function someMethod($uid)
    {
       return $this->someOtherMethod($uid);
    }

}

哪个运行没有错误.

然后测试脚本SomeValidatorTest.php看起来像这样:

<?php

use App\Services\Validators\SomeValidator;


class SomeValidatorTest extends TestCase
{
    public function __construct(SomeValidator $validator)
    {
        $this->validator = $validator;
    }

    public function testBasicExample()
    {
        $result = $this->validator->doSomething();
    }
}

仅当测试脚本通过'./vendor/bin/phpunit'运行时才会显示错误.测试类似乎在没有声明依赖项的情况下启动并引发错误.有谁知道如何解决这一问题？提前致谢.
