Laravel 5.2 - 为 foreach() 提供的参数无效 - 使用 phpunit

Question

我在使用 phpunit 命令测试我的应用程序时遇到上述错误。

public function testProductCreationFailsWhenNameNotProvided()
{
    $product = factory(\App\Product::class)->make(['name' => '']);

    $this->post(route('api.products.store'), $product->jsonSerialize())
        ->seeJson(['name' => ['The name field is required.']]) /*line 86*/
        ->assertResponseStatus(422);
}

完整的错误报告在这里：

There was 1 error:
1) ExampleTest::testProductCreationFailsWhenNameNotProvided
ErrorException: Invalid argument supplied for foreach()
C:\xampp\htdocs\product-  service\vendor\laravel\framework\src\Illuminate\Support\Arr.php:494

我承认这段代码不是我的原创 - 它是从 Laravel 教程中复制的。它在那里工作得很好。不幸的是，这个相关问题的答案也没有帮助我。

我试图修改它以便将 json 数组作为参数传递

public function testProductCreationFailsWhenNameNotProvided()
    {
        $product = factory(\App\Product::class)->make(['name' => '']);

        $this->post(route('api.products.store'), $product->jsonSerialize())
            ->seeJson(json_encode(array('name' => ['The name field is required.'])))
            ->assertResponseStatus(422);
    }

但后来我得到了这个错误：

1) ExampleTest::testProductCreationFailsWhenNameNotProvided
TypeError: Argument 1 passed to Illuminate\Foundation\Testing\TestCase::seeJson() must be of the type array, string given, called in C:\xampp\htdocs\product-service\tests\ExampleTest.php on line 86

Answer 1

1) ExampleTest::testProductCreationFailsWhenNameNotProvided TypeError: Argument 1 passed to Illuminate\Foundation\Testing\TestCase::seeJson() must be of the type array, string given, called in C:\xampp\htdocs\product-service\tests\ExampleTest.php on line 86

此错误告诉您您在此处传递了错误的类型：

->seeJson(json_encode(array('name' => ['The name field is required.'])))

您必须将其更改为如下所示，然后它应该可以正常工作。

->seeJson(array('name' => ['The name field is required.']))
