Question

使用phpunit命令测试我的应用程序时出现上述错误。

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

我承认这段代码原本不是我的 - 它是从Laravel教程复制的。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。 Laravel 5.1 + PHPunit - API test returns always invalid argument error foreach

我尝试修改它以将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);
    }

然后我收到了这个错误：

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：传递给Illuminate \ Foundation \ Testing \ TestCase :: seeJson（）的参数1必须是类型数组，给定字符串，在第86行的C：\ xampp \ htdocs \ product-service \ tests \ ExampleTest.php中调用< / p>

此错误告诉您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此，然后它才能正常工作。

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

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