测试

所有本指南内的示例都会使用 Pest 编写。当然，你也可以使用 PHPUnit。

因为表单构造器是基于 Livewire 组件的，因此你也可以使用 Livewire 测试辅助函数。不过，我们自定义了一些测试辅助函数，让你可以用于表单测试：

#填充表单

要填充表单，请将数据传入 fillform()：

use function Pest\Livewire\livewire;
 
livewire(CreatePost::class)
    ->fillForm([
        'title' => fake()->sentence(),
        // ...
    ]);
use function Pest\Livewire\livewire;

livewire(CreatePost::class)
    ->fillForm([
        'title' => fake()->sentence(),
        // ...
    ]);

注意，如果一个 Livewire 组件中有多个表单，你可以使用 fillForm([...], 'createPostForm') 指定你想要填充哪个表单。

使用 assertFormSet() 检测表单是否有数据：

use Illuminate\Support\Str;
use function Pest\Livewire\livewire;
 
it('can automatically generate a slug from the title', function () {
    $title = fake()->sentence();
 
    livewire(CreatePost::class)
        ->fillForm([
            'title' => $title,
        ])
        ->assertFormSet([
            'slug' => Str::slug($title),
        ]);
});
use Illuminate\Support\Str;
use function Pest\Livewire\livewire;

it('can automatically generate a slug from the title', function () {
    $title = fake()->sentence();

    livewire(CreatePost::class)
        ->fillForm([
            'title' => $title,
        ])
        ->assertFormSet([
            'slug' => Str::slug($title),
        ]);
});

注意，如果一个 Livewire 组件中有多个表单，你可以使用 assertFormSet([...], 'createPostForm') 指定你想要检测哪个表单。

#验证

使用 assertHasFormErrors() 断言表单中的数据是否有效验证：

use function Pest\Livewire\livewire;
 
it('can validate input', function () {
    livewire(CreatePost::class)
        ->fillForm([
            'title' => null,
        ])
        ->assertHasFormErrors(['title' => 'required']);
});
use function Pest\Livewire\livewire;

it('can validate input', function () {
    livewire(CreatePost::class)
        ->fillForm([
            'title' => null,
        ])
        ->assertHasFormErrors(['title' => 'required']);
});

同时 assertHasNoFormErrors() 断言没有验证错误：

use function Pest\Livewire\livewire;
 
livewire(CreatePost::class)
    ->fillForm([
        'title' => fake()->sentence(),
        // ...
    ])
    ->call('save')
    ->assertHasNoFormErrors();
use function Pest\Livewire\livewire;

livewire(CreatePost::class)
    ->fillForm([
        'title' => fake()->sentence(),
        // ...
    ])
    ->call('save')
    ->assertHasNoFormErrors();

注意，如果一个 Livewire 组件中有多个表单，你可以将指定表单的名字作为第二个参数，像这样 assertHasFormErrors(['title' => 'required'], 'createPostForm') 或 assertHasNoFormErrors([], 'createPostForm') 传入。

#表单存在

断言 Livewire 组件中有一个表单，请使用 assertFormExists():

use function Pest\Livewire\livewire;
 
it('has a form', function () {
    livewire(CreatePost::class)
        ->assertFormExists();
});
use function Pest\Livewire\livewire;

it('has a form', function () {
    livewire(CreatePost::class)
        ->assertFormExists();
});

注意，如果一个 Livewire 组件中有多个表单，你可以将指定的表单名传入 assertFormExists('createPostForm').

#字段

断言表单中有某个给定字段，将字段名传入到 assertFormFieldExists()：

use function Pest\Livewire\livewire;
 
it('has a title field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldExists('title');
});
use function Pest\Livewire\livewire;

it('has a title field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldExists('title');
});

你也可以传入函数作为额外的参数，来断言一个字段传入了一个“真值测试”。这对断言一个字段有某个特定配置非常有用：

use function Pest\Livewire\livewire;
 
it('has a title field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldExists('title', function (TextInput $field): bool {
            return $input->isDisabled();
        });
});
use function Pest\Livewire\livewire;

it('has a title field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldExists('title', function (TextInput $field): bool {
            return $input->isDisabled();
        });
});

注意，如果你的 Livewire 组件有多个表单，你可以使用 assertFormFieldExists('title', 'createPostForm') 指定哪个表单，要检测字段是否存在。

#Hidden 字段

断言表单中有某个字段可见，将字段名传入到 assertFormFieldIsVisible():

use function Pest\Livewire\livewire;
 
test('title is visible', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsVisible('title');
});
use function Pest\Livewire\livewire;

test('title is visible', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsVisible('title');
});

或者断言表单中隐藏某个字段，将字段名传入到 assertFormFieldIsHidden():

use function Pest\Livewire\livewire;
 
test('title is hidden', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsHidden('title');
});
use function Pest\Livewire\livewire;

test('title is hidden', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsHidden('title');
});

请注意，assertFormFieldIsHidden() 和 assertFormFieldIsVisible() 都将字段所属的指定表单名作为第二个参数，比如 assertFormFieldIsHidden('title', 'createPostForm')，进行传递。

#Disabled 字段

断言字段 enabled，将字段名传入到 assertFormFieldIsEnabled():

use function Pest\Livewire\livewire;
 
test('title is enabled', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsEnabled('title');
});
use function Pest\Livewire\livewire;

test('title is enabled', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsEnabled('title');
});

或者断言字段 disabled，将字段名传入到 assertFormFieldIsDisabled():

use function Pest\Livewire\livewire;
 
test('title is disabled', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsDisabled('title');
});
use function Pest\Livewire\livewire;

test('title is disabled', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsDisabled('title');
});

请注意，assertFormFieldIsEnabled() 和 assertFormFieldIsDisabled() 都将字段所属的指定表单名作为第二个参数，比如 assertFormFieldIsEnabled('title', 'createPostForm)，进行传递。
