Yii2 Codeception create a new test

Yii 2.0 Testing
1

Hi there,

Today I go through with Yii2 Codeception tests, I see there are built in tests, I don’t understand the file structure.

Can you pls explain briefly how this tool is working?

When I execute commands:


codecept build

and


codecept run

What happens actually?

I see this output:


codecept build

How I can create new test? I tried this: create a new method in frontend/controller/SiteController.php




public function actionMyTest(){

   return $this->render('myfile');

}

this is myfile.php


<?php


/* @var $this yii\web\View */


use yii\helpers\Html;


$this->title = 'My File';

$this->params['breadcrumbs'][] = $this->title;

?>

<div class="site-my-file">

    <h2><?= Html::encode($this->title) ?></h2>


    <p>This is the About page. You may modify the following file to customize its content:</p>


    <code><?= __FILE__ ?></code>

</div>

and again I run commands:


codecept build

and


codecept run

but my new created method doesn’t show in test?

How I can test my new method?


 actionMyTest()

I really need to understand this tool, I checked also codeception original site.

Thank you for your time.

codecept build only needs to be run once on setup or config changes.

To create a new test simply create a new file, for example "MysiteCept.php" in "tests/codeception/acceptance/":


<?php

$I = new AcceptanceTester($scenario);

$I->wantTo('ensure that mytest page works');

$I->amOnPage(Yii::$app->homeUrl.'/site/mypage');

$I->see('My File');

if you run the following command, the new test will be run with all existing acceptance tests:


codecept run acceptance
