如何在laravel中测试我的简单方法

我在laravel 5.3项目中有如下方法：

/**
* returns each section of current url in an array
*
* @return array
*/
public function getUrlPath()
{
    return explode("/", $this->request->path());
}

---

如何创建单元测试方法来测试此方法？我想我需要模拟http get请求和请求实例。但是，我不知道怎么做

你应该让你的方法像这样独立

use Request;
/**
* returns each section of current url in an array
*
* @return array
*/
public function getUrlPath(Request $request)
{
    return explode("/", $request->path());
}

您可以将

请求

作为参数添加到包含的类中，如下所示：

use Request; //it is a facade https://laravel.com/docs/5.3/facades 
class MyRequestHandler
{
    protected $request;
    public function __construct(Request $request)
    {
        $this->request = $request;
    }

    public function getUrlPath()
    {
        return explode("/", $this->request->path());
    }
}

public function testGetUrlPath(){
    $expected = ['url','to','path'];
    $request = Request::create(implode('/', $expected)); // https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/Request.php#L313
    $class = new MyRequestHandler($request);

    // Getting results of function so we can test that it has some properties which were supposed to have been set.
    $result = $class->getUrlPath();
    $this->assertEquals($expected, $result);
}

而测试是这样的：

use Request; //it is a facade https://laravel.com/docs/5.3/facades 
class MyRequestHandler
{
    protected $request;
    public function __construct(Request $request)
    {
        $this->request = $request;
    }

    public function getUrlPath()
    {
        return explode("/", $this->request->path());
    }
}

public function testGetUrlPath(){
    $expected = ['url','to','path'];
    $request = Request::create(implode('/', $expected)); // https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/Request.php#L313
    $class = new MyRequestHandler($request);

    // Getting results of function so we can test that it has some properties which were supposed to have been set.
    $result = $class->getUrlPath();
    $this->assertEquals($expected, $result);
}

如果您认为helper方法是自包含的，并将依赖项作为参数提供，可能会更好。这将使它易于测试<代码>公共函数getUrlPathElements（$path）将允许您直接对其进行单元测试，而无需使用Laravel路由机制。您指的是类似于此问题的方法吗？
