Testing

This package uses codeception for testing. To run the tests, run the following commands:

php.exe .\vendor\bin\codecept run for all test suites

Unit tests

run php.exe .\vendor\bin\codecept run Unit in the root directory of this repository.

Functional tests

run php.exe .\vendor\bin\codecept run Functional in the root directory of this repository.

Accpetance tests

To be able to run acceptance tests, a few requirements are needed:

For Windows:\

• install java runtime environment
• install nodejs
• install selenium-standalone: npm install -g selenium-standalone
• start selenium-standalone: selenium-standalone install && selenium-standalone start
• host a yii2 application on a server or locally via ./yii serve
  • add this plugin as a dependency to your composer.json and update dependencies
  • site must be reachable over http://formwizard.com/
  • add an action actionTest to the SiteController, as described below
  • this action must return a view file, as described below
  • run php.exe .\vendor\bin\codecept run Acceptance

For Linux:
Never did that before, but I think it is similar to the Windows setup.

The action in the SiteController:

public function actionTest(): string
{
    include __DIR__ . '/../vendor/sandritsch91/yii2-widget-form-wizard/tests/Support/Data/models/User.php';

    $model = new User();

    if (Yii::$app->request->post() && $model->load(Yii::$app->request->post()) && $model->validate()) {
        return 'success';
    }

    return $this->render('test', [
        'model' => new User()
    ]);
}

The view returned by the action:

/** @var User $model */

use sandritsch91\yii2\formwizard\FormWizard;
use sandritsch91\yii2\formwizard\tests\Support\Data\models\User;

$wizard = FormWizard::widget([
    'model' => $model,
    'tabOptions' => [
        'options' => [
            'class' => 'mb-3'
        ],
        'items' => [
            [
                'label' => 'Step 1',
                'view' => '@app/vendor/sandritsch91/yii2-widget-form-wizard/tests/Support/Data/views/site/step1',
                'linkOptions' => [
                    'id' => 'step1-link',,
                    'params' => [
                        'test' => 'some test variable'
                    ]
                ]
            ],
            [
                'label' => 'Step 2',
                'view' => '@app/vendor/sandritsch91/yii2-widget-form-wizard/tests/Support/Data/views/site/step2',
                'linkOptions' => [
                    'id' => 'step2-link',
                ]
            ],
            [
                'label' => 'Step 3',
                'view' => '@app/vendor/sandritsch91/yii2-widget-form-wizard/tests/Support/Data/views/site/step3',
                'linkOptions' => [
                    'id' => 'step3-link',
                ]
            ]
        ],
        'navType' => 'nav-pills'
    ],
    'validateSteps' => [
        ['firstname', 'lastname'],
        ['username', 'password', 'password_validate'],
        ['email']
    ],
    'clientOptions' => [
        'keepPosition' => true
    ]
]);

echo \yii\helpers\Html::tag('div', $wizard, [
    'class' => 'col-4'
]);

After the initial installation, you only have to start the selenium-standalone server selenium-standalone start and run the tests php.exe .\vendor\bin\codecept run Acceptance in the root directory of this repository.

If you do not want to setup an application, just run the unit and functional tests by running php.exe .\vendor\bin\codecept run Unit,Functional, I can modify and run the acceptance tests for you, after you opened a pull request.
