Call to undefined function tests\codeception\unit\models\expect()


I am trying to perform unit testing using the default ContactFormTest inside the yii2 basic application. But it provides me the following error.

E:\xampp\htdocs\news\tests>codecept run unit codeception\unit\models\ContactForm
Test.php
Codeception PHP Testing Framework v2.0.16

in E:\xampp\htdocs\news\tests\codeception\unit\models\ContactFormTest.php:46

Stack trace:

Below is my ContactFormTest.php

namespace tests\codeception\unit\models;

use app\models\ContactForm;
use Yii;
use yii\codeception\TestCase;
use Codeception\Specify;
use Codeception\Util\Debug;

class ContactFormTest extends TestCase
{
    use Specify;

    protected function setUp()
    {
        parent::setUp();
        Yii::$app->mailer->fileTransportCallback = function ($mailer, $message) {
            return 'testing_message.eml';
        };
    }

    protected function tearDown()
    {
        unlink($this->getMessageFile());
        parent::tearDown();
    }

    public function testContact()
    {
        /** @var ContactForm $model */
        $model = $this->getMockBuilder('app\models\ContactForm')
            ->setMethods(['validate'])
            ->getMock();
        $model->expects($this->once())->method('validate')->will($this->returnValue(true));

        $model->attributes = [
            'name' => 'Tester',
            'email' => '[email protected]',
            'subject' => 'very important letter subject',
            'body' => 'body of current message',
        ];
        //Debug::debug($model->contact('[email protected]'));
        //die();
        $this->specify('email should be send', function () use ($model) {
            expect('ContactForm::contact() should return true', $model->contact('[email protected]'))->true(); //this throws the error
            expect('email file should exist', file_exists($this->getMessageFile()))->true();
        });

        $this->specify('message should contain correct data', function () use ($model) {
            $emailMessage = file_get_contents($this->getMessageFile());

            expect('email should contain user name', $emailMessage)->contains($model->name);
            expect('email should contain sender email', $emailMessage)->contains($model->email);
            expect('email should contain subject', $emailMessage)->contains($model->subject);
            expect('email should contain body', $emailMessage)->contains($model->body);
        });
    }

    private function getMessageFile()
    {
        return Yii::getAlias(Yii::$app->mailer->fileTransportPath) . '/testing_message.eml';
    }

}

And unit.suite.yml

# Codeception Test Suite Configuration

# suite for unit (internal) tests.
# RUN `build` COMMAND AFTER ADDING/REMOVING MODULES.

class_name: UnitTester
modules:
    config:
        Db:
            dsn: 'mysql:host=127.0.0.1;dbname=news_tests'
            user: 'root'
            password: ''
            dump: 'tests/_data/dump.sql'
            populate: false
            cleanup: false
            reconnect: true

How to fix this?


Solution

  • Does your IDE recognize the expect function calls inside specify?

    If not, then try adding specify and verify to require-dev Composer dependencies as specified in the manual:

    "require-dev": {
        ...
        "codeception/specify": "*",
        "codeception/verify": "*"
    }
    

    And run composer update.
