测试

所有本指南内的示例都会使用 Pest 编写。

由于后台面板的所有页面都是 Livewire 组件，我们始终都在使用 Livewire 测试函数。 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​

确保你在测试案例(TestCase)中有权限访问后台面板:

protected function setUp(): void
{
    parent::setUp();

    $this->actingAs(User::factory()->create());
}

资源​

页面​

列表​

路由 & 渲染​

要确保 PostResource 的列表页渲染成功，需生成页面 URL、发送请求到该 URL 并检查是否成功：

it('can render page', function () {
    $this->get(PostResource::getUrl('index'))->assertSuccessful();
});
表格​

Filament 内含一系列辅助函数用来测试表格。表格测试全指南可查阅表格构造器文档。

要使用表格测试辅助函数，在持有该表格的资源列表类中使用断言：

use function Pest\Livewire\livewire;

it('can list posts', function () {
    $posts = Post::factory()->count(10)->create();

    livewire(PostResource\Pages\ListPosts::class)
        ->assertCanSeeTableRecords($posts);
});

新建​

路由 & 渲染​

检查 PostResource 的新建页是否可以成功渲染，生成页面 URL，发起请求到该地址，检测是否成功。

it('can render page', function () {
    $this->get(PostResource::getUrl('create'))->assertSuccessful();
});
新建​

你可以通过设置(set())表单的每个属性，然后断言数据库是否包含这一记录，检查数据是否成功保存到数据库:

use function Pest\Livewire\livewire;

it('can create', function () {
    $newData = Post::factory()->make();

    livewire(PostResource\Pages\CreatePost::class)
        ->fillForm([
            'author_id' => $newData->author->getKey(),
            'content' => $newData->content,
            'tags' => $newData->tags,
            'title' => $newData->title,
        ])
        ->call('create')
        ->assertHasNoFormErrors();

    $this->assertDatabaseHas(Post::class, [
        'author_id' => $newData->author->getKey(),
        'content' => $newData->content,
        'tags' => json_encode($newData->tags),
        'title' => $newData->title,
    ]);
});
验证​

使用 assertHasFormErrors() 检查表单中的数据验证是否正确：

use function Pest\Livewire\livewire;

it('can validate input', function () {
    $newData = Post::factory()->make();

    livewire(PostResource\Pages\CreatePost::class)
        ->fillForm([
            'title' => null,
        ])
        ->call('create')
        ->assertHasFormErrors(['title' => 'required']);
});

编辑​

路由 & 渲染​

检查 PostResource 的编辑页是否可以成功渲染，生成页面 URL，发起请求到该地址，检测是否成功：

it('can render page', function () {
    $this->get(PostResource::getUrl('edit', [
        'record' => Post::factory()->create(),
    ]))->assertSuccessful();
});
填充已有数据​

检测当前表单是否正确填充了数据库的数据，你可以使用 assertFormSet() 断言表单中的数据是否匹配数据库记录：

use function Pest\Livewire\livewire;

it('can retrieve data', function () {
    $post = Post::factory()->create();

    livewire(PostResource\Pages\EditPost::class, [
        'record' => $post->getKey(),
    ])
        ->assertFormSet([
            'author_id' => $post->author->getKey(),
            'content' => $post->content,
            'tags' => $post->tags,
            'title' => $post->title,
        ]);
});
保存​

你可可以在 fillForm() 使用表单数据，检查数据是否正确存入数据库，并断言数据库中是否包含匹配的记录：

use function Pest\Livewire\livewire;

it('can save', function () {
    $post = Post::factory()->create();
    $newData = Post::factory()->make();

    livewire(PostResource\Pages\EditPost::class, [
        'record' => $post->getKey(),
    ])
        ->fillForm([
            'author_id' => $newData->author->getKey(),
            'content' => $newData->content,
            'tags' => $newData->tags,
            'title' => $newData->title,
        ])
        ->call('save')
        ->assertHasNoFormErrors();

    expect($post->refresh())
        ->author_id->toBe($newData->author->getKey())
        ->content->toBe($newData->content)
        ->tags->toBe($newData->tags)
        ->title->toBe($newData->title);
});
验证​

使用 assertHasFormErrors() 检测表单中的数据是否被正确验证:

use function Pest\Livewire\livewire;

it('can validate input', function () {
    $post = Post::factory()->create();
    $newData = Post::factory()->make();

    livewire(PostResource\Pages\EditPost::class, [
        'record' => $post->getKey(),
    ])
        ->fillForm([
            'title' => null,
        ])
        ->call('save')
        ->assertHasFormErrors(['title' => 'required']);
});
删除​

你可以使用 callPageAction() 测试 DeleteAction:

use Filament\Pages\Actions\DeleteAction;
use function Pest\Livewire\livewire;

it('can delete', function () {
    $post = Post::factory()->create();

    livewire(PostResource\Pages\EditPost::class, [
        'record' => $post->getKey(),
    ])
        ->callPageAction(DeleteAction::class);

    $this->assertModelMissing($post);
});

你可以使用 assertPageActionHidden() 断言 DeleteAction 对特定用户隐藏：

use Filament\Pages\Actions\DeleteAction;
use function Pest\Livewire\livewire;

it('can not delete', function () {
    $post = Post::factory()->create();

    livewire(PostResource\Pages\EditPost::class, [
        'record' => $post->getKey(),
    ])
        ->assertPageActionHidden(DeleteAction::class);

    $this->assertModelMissing($post);
});

查看​

路由 & 渲染​

检查 PostResource 的编辑页是否可以成功渲染，生成页面 URL，发起请求到该地址，检测是否成功：

it('can render page', function () {
    $this->get(PostResource::getUrl('view', [
        'record' => Post::factory()->create(),
    ]))->assertSuccessful();
});
填充已有数据​

检测当前表单是否正确填充了数据库的数据，你可以使用 assertFormSet() 断言表单中的数据是否匹配数据库记录：

use function Pest\Livewire\livewire;

it('can retrieve data', function () {
    $post = Post::factory()->create();

    livewire(PostResource\Pages\ViewPost::class, [
        'record' => $post->getKey(),
    ])
        ->assertFormSet([
            'author_id' => $post->author->getKey(),
            'content' => $post->content,
            'tags' => $post->tags,
            'title' => $post->title,
        ]);
});

关联管理器​

渲染​

要检测关联管理器是否渲染成功，挂载 Livewire 组件：

use function Pest\Livewire\livewire;

it('can render relation manager', function () {
    $category = Category::factory()
        ->has(Post::factory()->count(10))
        ->create();

    livewire(CategoryResource\RelationManagers\PostsRelationManager::class, [
        'ownerRecord' => $category,
    ])
        ->assertSuccessful();
});
表格​

Filament 内含一系列辅助函数用于测试表格。表格测试全指南可查阅表格构造器文档。

要使用表格测试辅助函数，在持有该表格的关联管理器类中使用断言：

use function Pest\Livewire\livewire;

it('can list posts', function () {
    $category = Category::factory()
        ->has(Post::factory()->count(10))
        ->create();

    livewire(CategoryResource\RelationManagers\PostsRelationManager::class, [
        'ownerRecord' => $category,
    ])
        ->assertCanSeeTableRecords($category->posts);
});

页面操作​

你可以在 callPageAction() 中传入操作名或类调用页面操作:

use function Pest\Livewire\livewire;

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

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

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

使用 data 参数，将数组数据传入操作：

use function Pest\Livewire\livewire;

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

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

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

assertHasNoPageActionErrors() 用于断言提交操作表单时没有出现验证错误。

要断言数据出现验证错误，像在 Livewire 中使用 assertHasErrors() 一样，使用 assertHasPageActionErrors()。

use function Pest\Livewire\livewire;

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

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

使用 assertPageActionDataSet() 断言页面操作是否预装了数据：

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,
    ])
        ->mountPageAction('send')
        ->assertPageActionDataSet([
            'email' => $recipientEmail,
        ])
        ->callMountedPageAction()
        ->assertHasNoPageActionErrors();
        
    expect($invoice->refresh())
        ->isSent()->toBeTrue()
        ->recipient_email->toBe($recipientEmail);
});

使用 assertPageActionHidden() 断言页面操作是否对用户隐藏。

use function Pest\Livewire\livewire;

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

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