测试

概述

所有本指南内的示例都会使用 Pest 编写。不过，你可以轻松将其应用到 PHPUnit。

由于所有 Action 都挂载到 Livewire 组件，我们始终都在使用 Livewire 测试辅助函数。如果你之前从未测试过 Livewire 组件，请阅读 Livewire 文档下的这一向导。

开始

将 Action 名或者类传入 callAction()，你可以调用 Action：

use function Pest\Livewire\livewire;

it('can send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callAction('send');

    expect($invoice->refresh())
        ->isSent()->toBeTrue();
});

要将数据数组传递给 Action，请使用 data 参数：

use function Pest\Livewire\livewire;

it('can send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callAction('send', data: [
            'email' => $email = fake()->email(),
        ])
        ->assertHasNoActionErrors();

    expect($invoice->refresh())
        ->isSent()->toBeTrue()
        ->recipient_email->toBe($email);
});

如果你只需要设置 Action 的数据，而不用马上调用这些数据，你可以使用 setActionData()：

use function Pest\Livewire\livewire;

it('can send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->mountAction('send')
        ->setActionData('send', data: [
            'email' => $email = fake()->email(),
        ])
});

执行

要断言 Action 是否停止，你可以使用 assertActionHalted()：

use function Pest\Livewire\livewire;

it('stops sending if invoice has no email address', function () {
    $invoice = Invoice::factory(['email' => null])->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callAction('send')
        ->assertActionHalted('send');
});

错误

assertHasNoActionErrors() 用于断言提交表单时，没有发生验证错误。

要断言带有数据的验证错误，请使用 assertHasActionErrors()，类似于 Livewire 中的 assertHasErrors()。

use function Pest\Livewire\livewire;

it('can validate invoice recipient email', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callAction('send', data: [
            'email' => Str::random(),
        ])
        ->assertHasActionErrors(['email' => ['email']]);
});

要断言 Action 已经预填数据，请使用 assertActionDataSet() 方法：

use function Pest\Livewire\livewire;

it('can send invoices to the primary contact by default', function () {
    $invoice = Invoice::factory()->create();
    $recipientEmail = $invoice->company->primaryContact->email;

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->mountAction('send')
        ->assertActionDataSet([
            'email' => $recipientEmail,
        ])
        ->callMountedAction()
        ->assertHasNoActionErrors();
        
    expect($invoice->refresh())
        ->isSent()->toBeTrue()
        ->recipient_email->toBe($recipientEmail);
});

Action 状态

使用 assertActionExists() 或 assertActionDoesNotExist() 方法，你可以断言 Action 存在或不存在：

use function Pest\Livewire\livewire;

it('can send but not unsend invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionExists('send')
        ->assertActionDoesNotExist('unsend');
});

要断言 Action 对用户隐藏或可见，请使用 assertActionHidden() 或 assertActionVisible() 方法：

use function Pest\Livewire\livewire;

it('can only print invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionHidden('send')
        ->assertActionVisible('print');
});

要断言 Aciton 对用户启用或者禁用，请使用 assertActionEnabled() 或 assertActionDisabled() 方法：

use function Pest\Livewire\livewire;

it('can only print a sent invoice', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionDisabled('send')
        ->assertActionEnabled('print');
});

要断言 Action 是否以正确的顺序存在，请使用 assertActionsExistInOrder()：

use function Pest\Livewire\livewire;

it('can have actions in order', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionsExistInOrder(['send', 'export']);
});

要断言 Action 是否对用户隐藏，请使用 assertActionHidden() 方法：

use function Pest\Livewire\livewire;

it('can not send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionHidden('send');
});

Button 外观

要断言 Action 的标签正确，可以使用 assertActionHasLabel() 或 assertActionDoesNotHaveLabel()：

use function Pest\Livewire\livewire;

it('send action has correct label', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionHasLabel('send', 'Email Invoice')
        ->assertActionDoesNotHaveLabel('send', 'Send');
});

要断言 Action 按钮显示了正确的图标，可以使用 assertActionHasIcon() 或 assertActionDoesNotHaveIcon()

use function Pest\Livewire\livewire;

it('when enabled the send button has correct icon', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionEnabled('send')
        ->assertActionHasIcon('send', 'envelope-open')
        ->assertActionDoesNotHaveIcon('send', 'envelope');
});

要断言 Action 按钮显示了正确的颜色，可以使用 assertActionHasColor() 或 assertActionDoesNotHaveColor()：

use function Pest\Livewire\livewire;

it('actions display proper colors', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionHasColor('delete', 'danger')
        ->assertActionDoesNotHaveColor('print', 'danger');
});

URL

要断言 Action 拥有正确的 URL，你可以使用 assertActionHasUrl()、assertActionDoesNotHaveUrl()、assertActionShouldOpenUrlInNewTab() 和 assertActionShouldNotOpenUrlInNewTab()：

use function Pest\Livewire\livewire;

it('links to the correct Filament sites', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertActionHasUrl('filament', 'https://filamentphp.com/')
        ->assertActionDoesNotHaveUrl('filament', 'https://github.com/filamentphp/filament')
        ->assertActionShouldOpenUrlInNewTab('filament')
        ->assertActionShouldNotOpenUrlInNewTab('github');
});
