时间戳使我的 phpunit 测试失败

Question

当我使用以下 PostResource 和 Post Test 时，我的测试成功了：

PostResource.php

public function toArray($request)
{
    return [
        'id' => $this->id,
        'title' => $this->title,
        'content' => $this->content,
        'slug' => $this->slug,
    ];
}

PostController.php

public function show(Post $post)
{
    return new PostResource($post);
}

ReadPostTest.php

/** @test */
public function a_user_can_read_a_single_post()
{
    $post = factory(Post::class)->create([
        'title' => 'A new post',
        'content' => "Some content",
        'slug' => "a-new-post",
    ]);

    //dd($post);

    $response = $this->json('GET', '/posts/' . $post->id)
            ->assertStatus(200)
            ->assertJsonFragment([ 'data' => [
                'title' => 'A new post',
                'content' => "Some content",
                'slug' => "a-new-post",
            ]]);

}

当我将 created_at 和 updated_at 添加到我的测试和资源中时，我遇到了失败。当我没有添加.000000Z 时，下面的测试显示。

phpunit

There was 1 failure:

我尝试添加 000000Z 并遇到了同样的问题。

There was 1 failure:

似乎我的 created_at 和 up_dated at 时间戳被搞砸了，我不知道为什么？ 2019-12-20T21:42:33.000000Z这可能是我的测试失败的原因。我该如何解决这个问题？

在你的后期模型工厂中使用碳，然后在 json 断言中使用 $post->created_at 和 $post->updated_at：

public function a_user_can_read_a_single_post()
{
    $post = factory(Post::class)->create([
        'title' => 'A new post',
        'content' => "Some content",
        'slug' => "a-new-post",
        "updated_at" => Carbon::now()->timestamp,
        "created_at" => Carbon::now()->timestamp
    ]);

    //dd($post);

    $response = $this->json('GET', '/posts/' . $post->id)
            ->assertStatus(200)
            ->assertJsonFragment([ 'data' => [
                'id' => 1,
                'title' => 'A new post',
                'content' => "Some content",
                'slug' => "a-new-post",
                "updated_at" => $post->updated_at,
                "created_at" => $post->created_at
            ]]);

}

由于某种原因，一串时间戳不起作用。希望其他人可以评论为什么。

您可能想使用 Carbon 的 setTestNow() 来修正测试期间“现在”的含义。

假设您使用的是 Laravel。

// Immutable, so you don't go insane.
$now = \Carbon\CarbonImmutable::now()->micro(0);

// Fix Carbon's 'now' to that time
\Illuminate\Support\Carbon::setTestNow($now)
// \Carbon\CarbonImmutable::setTestNow($now);

// Your tests here
// u = microseconds, but it's not set to '000000' in 'now', if you forget `->micro(0)`.
// The 'Y-m-d\TH:i:s.u\Z' format works with Laravel 6.20.19 in march 2021, but YMMV.
// ->assertJSon(['created_at' => $now->utc()->format('Y-m-d\TH:i:s.000000\Z'),])

// Release Carbon's 'now' time to follow your clock again.
\Illuminate\Support\Carbon::setTestNow($now)
// \Carbon\CarbonImmutable::setTestNow($now);

您似乎在为时间戳格式而苦苦挣扎。我遇到了同样的问题，并通过 Carbon 文档中的 JSON 序列化解决了它。在您的情况下，它必须如下所示：

public function a_user_can_read_a_single_post()
{
    $post = factory(Post::class)->create([
        'title' => 'A new post',
        'content' => "Some content",
        'slug' => "a-new-post",
        "updated_at" => Carbon::now()->timestamp,
        "created_at" => Carbon::now()->timestamp
    ]);

    $response = $this->json('GET', '/posts/' . $post->id)
            ->assertStatus(200)
            ->assertJsonFragment([ 'data' => [
                'id' => 1,
                'title' => 'A new post',
                'content' => "Some content",
                'slug' => "a-new-post",
                "updated_at" => $post->updated_at->jsonSerialize(),
                "created_at" => $post->created_at->jsonSerialize()
            ]]);

}

可能有点晚了，但希望对其他人有所帮助。 祝你好运哥们。
