Php Laravel测试服务依赖项注入错误

从结论开始，我得到以下错误：

[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);
    }

}

<?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();
    }
}

<?php

class SomeValidatorTest extends TestCase
{
    public function __construct()
    {
        $this->validator = \App::make('App\Services\Validators\SomeValidator');
    }

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

您不能将类注入测试（据我所知），因为它们不是由laravel/phpUnit自动解析的

正确的方法是通过laravel的
app
facade
make
（解析）它们。您的测试脚本应该如下所示：

<?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);
    }

}

<?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();
    }
}

<?php

class SomeValidatorTest extends TestCase
{
    public function __construct()
    {
        $this->validator = \App::make('App\Services\Validators\SomeValidator');
    }

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