如何將函數從閉包轉移到普通函數

Question

我正在嘗試讓害蟲測試文件更易於閱讀。

目前，我有一些標準測試：

test('can get subscribers latest subscription', function () {
     $this->seed(PlansTestSeeder::class);
    $this->seed(SubscriptionsTestSeeder::class);

    $this->assertDatabaseCount('plans', 2);
    $this->assertDatabaseCount('subscriptions', 0);


    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "bronze")->first()->id
    ]);
    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "silver")->first()->id
    ]);
    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "silver")->first()->id,
        "status" => "expired"
    ]);
    Subscription::factory()->trashed()->create();

    $this->assertDatabaseCount('subscriptions', 4);

});

test('can get subscribers active subscriptions', function () {
    $this->seed(PlansTestSeeder::class);
    $this->seed(SubscriptionsTestSeeder::class);

    $silverPlan = Plan::where("slug", "silver")->first();

    $subscription1 = Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "silver")->first()->id,
        "subscriber_id" => 1,
        "subscriber_type" => "ApresourcingFramework\Billing\Tests\Models\Subscriber",
        "created_at" => now()->subDays(2),
        "started_at" => now()->subDays(2)
    ]);
    $subscription2 = Subscription::factory()->create([
        "plan_id" => $silverPlan->id,
        "subscriber_id" => 1,
        "subscriber_type" => "ApresourcingFramework\Billing\Tests\Models\Subscriber",
        "created_at" => now()->subDays(1),
        "started_at" => now()->subDays(1)
    ]);

    $user = Subscriber::find(1);
    $subscription = $user->latestSubscription();
    expect($subscription->id)->toBe($subscription2->id);
});

但為了提醒自己我寫了哪些測試，我必須一遍又一遍地上下滾動頁面。

我想做的是更改為以下內容：

test('can get subscribers latest subscription', getLatestSubscription());
test('can get subscribers active subscriptions', getActiveSubscriptions());

function getLatestSubscription() {
    /// function code here
});

function getActiveSubscriptions() {
    // function code here
});

但是，測試函數包含對 $this 的引用，它在正常閉包中可用，但在標準函數中不可用，因為我在此處設定了它。

編輯：我正在使用 laravel pest 外掛 - 我不確定這是否會對 $this 的使用產生影響

有辦法解決這個問題嗎？

感謝回覆中的一些提示。不像我希望的那樣整潔，但至少這意味著所有測試（“測試描述”）呼叫都位於 php 檔案底部的一個位置。

$createSubscription = function () {

    $this->seed(PlansTestSeeder::class);
    $this->seed(SubscriptionsTestSeeder::class);

    $this->assertDatabaseCount('plans', 2);
    $this->assertDatabaseCount('subscriptions', 0);


    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "bronze")->first()->id
    ]);
    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "silver")->first()->id
    ]);
    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "silver")->first()->id,
        "status"  => "expired"
    ]);
    Subscription::factory()->trashed()->create();

    $this->assertDatabaseCount('subscriptions', 4);

};

$createBronzeSubscription = function () {
    $this->seed(PlansTestSeeder::class);
    $this->seed(SubscriptionsTestSeeder::class);

    Subscription::factory()->create([
        "plan_id" => Plan::where("slug", "bronze")->first()->id
    ]);

    $this->assertDatabaseCount('subscriptions', 1);
};


test('can create subscription', function () use ($createSubscription) {
    return \Closure::bind(\Closure::fromCallable($createSubscription), $this, get_class($this))($this);
});

test('can create bronze subscription', function () use ($createBronzeSubscription) {
    return \Closure::bind(\Closure::fromCallable($createBronzeSubscription), $this, get_class($this))($this);
});
