Yii1

This module provides integration with Yii Framework 1.1.

The following configurations are available for this module:

• appPath - full path to the application, include index.php</li>
• url - full url to the index.php entry script</li>

In your index.php you must return an array with correct configuration for the application:

For the simple created yii application index.php will be like this:

<?php
// change the following paths if necessary
$yii=dirname(__FILE__).'/../yii/framework/yii.php';
$config=dirname(__FILE__).'/protected/config/main.php';

// remove the following lines when in production mode
defined('YII_DEBUG') or define('YII_DEBUG',true);
// specify how many levels of call stack should be shown in each log message
defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL',3);
require_once($yii);
return array(
       'class' => 'CWebApplication',
       'config' => $config,
);

You can use this module by setting params in your functional.suite.yml:

actor: FunctionalTester
modules:
    enabled:
        - Yii1:
            appPath: '/path/to/index.php'
            url: 'http://localhost/path/to/index.php'
        - \Helper\Functional

You will also need to install Codeception-Yii Bridge which include component wrappers for testing.

When you are done, you can test this module by creating new empty Yii application and creating this Cept scenario:

 codecept.phar g:cept functional IndexCept

and write it as in example:

<?php
$I = new FunctionalTester($scenario);
$I->wantTo('Test index page');
$I->amOnPage('/index.php');
$I->see('My Web Application','#header #logo');
$I->click('Login');
$I->see('Login','h1');
$I->see('Username');
$I->fillField('#LoginForm_username','demo');
$I->fillField('#LoginForm_password','demo');
$I->click('#login-form input[type="submit"]');
$I->seeLink('Logout (demo)');
$I->click('Logout (demo)');
$I->seeLink('Login');

Then run codeception: php codecept.phar –steps run functional You must see “OK” and that all steps are marked with asterisk (*). Do not forget that after adding module in your functional.suite.yml you must run codeception “build” command.

Parts

If you ever encounter error message:

Yii1 module conflicts with WebDriver

you should include Yii module partially, with init part only

• init: only initializes module and not provides any actions from it. Can be used for unit/acceptance tests to avoid conflicts.

Acceptance Testing Example:

In acceptance.suite.yml:

class_name: AcceptanceTester
modules:
    enabled:
        - WebDriver:
            browser: firefox
            url: http://localhost
        - Yii1:
            appPath: '/path/to/index.php'
            url: 'http://localhost/path/to/index.php'
            part: init # to not conflict with WebDriver
        - \Helper\Acceptance

Actions

_findElements

hidden API method, expected to be used from Helper classes

Locates element using available Codeception locator types:

• XPath
• CSS
• Strict Locator

Use it in Helpers or GroupObject or Extension classes:

<?php
$els = $this->getModule('Yii1')->_findElements('.items');
$els = $this->getModule('Yii1')->_findElements(['name' => 'username']);

$editLinks = $this->getModule('Yii1')->_findElements(['link' => 'Edit']);
// now you can iterate over $editLinks and check that all them have valid hrefs

WebDriver module returns Facebook\WebDriver\Remote\RemoteWebElement instances PhpBrowser and Framework modules return Symfony\Component\DomCrawler\Crawler instances

• param $locator
• return array of interactive elements

_getResponseContent

hidden API method, expected to be used from Helper classes

Returns content of the last response Use it in Helpers when you want to retrieve response of request performed by another module.

<?php
// in Helper class
public function seeResponseContains($text)
{
   $this->assertContains($text, $this->getModule('Yii1')->_getResponseContent(), "response contains");
}
?>

• return string @throws ModuleException

_loadPage

hidden API method, expected to be used from Helper classes

Opens a page with arbitrary request parameters. Useful for testing multi-step forms on a specific step.

<?php
// in Helper class
public function openCheckoutFormStep2($orderId) {
    $this->getModule('Yii1')->_loadPage('POST', '/checkout/step2', ['order' => $orderId]);
}
?>

• param $method
• param $uri
• param array $parameters
• param array $files
• param array $server
• param null $content

_request

hidden API method, expected to be used from Helper classes

Send custom request to a backend using method, uri, parameters, etc. Use it in Helpers to create special request actions, like accessing API Returns a string with response body.

<?php
// in Helper class
public function createUserByApi($name) {
    $userData = $this->getModule('Yii1')->_request('POST', '/api/v1/users', ['name' => $name]);
    $user = json_decode($userData);
    return $user->id;
}
?>

Does not load the response into the module so you can’t interact with response page (click, fill forms). To load arbitrary page for interaction, use _loadPage method.

• param $method
• param $uri
• param array $parameters
• param array $files
• param array $server
• param null $content
• return mixed|Crawler @throws ExternalUrlException @see _loadPage

_savePageSource

<?php
// file is stored in 'tests/_data/prices.xls'
$I->attachFile('input[@type="file"]', 'prices.xls');
?>

• param $field
• param $filename

checkOption

Ticks a checkbox. For radio buttons, use the selectOption method instead.

<?php
$I->checkOption('#agree');
?>

• param $option

click

Perform a click on a link or a button, given by a locator. If a fuzzy locator is given, the page will be searched for a button, link, or image matching the locator string. For buttons, the “value” attribute, “name” attribute, and inner text are searched. For links, the link text is searched. For images, the “alt” attribute and inner text of any parent links are searched.

The second parameter is a context (CSS or XPath locator) to narrow the search.

Note that if the locator matches a button of type submit, the form will be submitted.

<?php
// simple link
$I->click('Logout');
// button of form
$I->click('Submit');
// CSS button
$I->click('#form input[type=submit]');
// XPath
$I->click('//form/*[@type=submit]');
// link in context
$I->click('Logout', '#nav');
// using strict locator
$I->click(['link' => 'Login']);
?>

$I->dontSee('Sign Up','//body/h1');           // with XPath
$I->dontSee('Sign Up', ['css' => 'body h1']); // with strict CSS locator

Note that the search is done after stripping all HTML tags from the body, so $I->dontSee('strong') will fail on strings like:

• <p>I am Stronger than thou</p>
• <script>document.createElement('strong');</script>

sendAjaxGetRequest

If your page triggers an ajax request, you can perform it manually. This action sends a GET ajax request with specified params.

See ->sendAjaxPostRequest for examples.

sendAjaxPostRequest

If your page triggers an ajax request, you can perform it manually. This action sends a POST ajax request with specified params. Additional params can be passed as array.

Example:

Imagine that by clicking checkbox you trigger ajax request which updates user settings. We emulate that click by running this ajax request manually.

<?php
$I->sendAjaxPostRequest('/updateSettings', array('notifications' => true)); // POST
$I->sendAjaxGetRequest('/updateSettings', array('notifications' => true)); // GET

• param $uri
• param $params

sendAjaxRequest

If your page triggers an ajax request, you can perform it manually. This action sends an ajax request with specified method and params.

Example:

You need to perform an ajax request specifying the HTTP method.

<?php
$I->sendAjaxRequest('PUT', '/posts/7', array('title' => 'new title'));

• param $method
• param $uri
• param $params

setCookie

Sets a cookie with the given name and value. You can set additional cookie params like domain, path, expires, secure in array passed as last argument.

<?php
$I->setCookie('PHPSESSID', 'el4ukv0kqbvoirg7nkp4dncpk3');
?>

• param $name
• param $val
• param array $params

submitForm

Submits the given form on the page, with the given form values. Pass the form field’s values as an array in the second parameter.

Although this function can be used as a short-hand version of fillField(), selectOption(), click() etc. it has some important differences:

• Only field names may be used, not CSS/XPath selectors nor field labels
• If a field is sent to this function that does not exist on the page, it will silently be added to the HTTP request. This is helpful for testing some types of forms, but be aware that you will not get an exception like you would if you called fillField() or selectOption() with a missing field.

Fields that are not provided will be filled by their values from the page, or from any previous calls to fillField(), selectOption() etc. You don’t need to click the ‘Submit’ button afterwards. This command itself triggers the request to form’s action.

You can optionally specify which button’s value to include in the request with the last parameter (as an alternative to explicitly setting its value in the second parameter), as button values are not otherwise included in the request.

Examples:

<?php
$I->submitForm('#login', [
    'login' => 'davert',
    'password' => '123456'
]);
// or
$I->submitForm('#login', [
    'login' => 'davert',
    'password' => '123456'
], 'submitButtonName');

For example, given this sample “Sign Up” form:

<form action="/sign_up">
    Login:
    <input type="text" name="user[login]" /><br/>
    Password:
    <input type="password" name="user[password]" /><br/>
    Do you agree to our terms?
    <input type="checkbox" name="user[agree]" /><br/>
    Select pricing plan:
    <select name="plan">
        <option value="1">Free</option>
        <option value="2" selected="selected">Paid</option>
    </select>
    <input type="submit" name="submitButton" value="Submit" />
</form>

You could write the following to submit it:

<?php
$I->submitForm(
    '#userForm',
    [
        'user' => [
            'login' => 'Davert',
            'password' => '123456',
            'agree' => true
        ]
    ],
    'submitButton'
);

Note that “2” will be the submitted value for the “plan” field, as it is the selected option.

You can also emulate a JavaScript submission by not specifying any buttons in the third parameter to submitForm.

<?php
$I->submitForm(
    '#userForm',
    [
        'user' => [
            'login' => 'Davert',
            'password' => '123456',
            'agree' => true
        ]

This function works well when paired with seeInFormFields() for quickly testing CRUD interfaces and form validation logic.

<?php
$form = [
     'field1' => 'value',
     'field2' => 'another value',
     'checkbox1' => true,
     // ...
];
$I->submitForm('#my-form', $form, 'submitButton');
// $I->amOnPage('/path/to/form-page') may be needed
$I->seeInFormFields('#my-form', $form);

Parameter values can be set to arrays for multiple input fields of the same name, or multi-select combo boxes. For checkboxes, you can use either the string value or boolean true/false which will be replaced by the checkbox’s value in the DOM.

<?php
$I->submitForm('#my-form', [
     'field1' => 'value',
     'checkbox' => [
         'value of first checkbox',
         'value of second checkbox',
     ],
     'otherCheckboxes' => [
         true,
         false,
         false
     ],
     'multiselect' => [
         'first option value',
         'second option value'
     ]
]);

Mixing string and boolean values for a checkbox’s value is not supported and may produce unexpected results.

Field names ending in [] must be passed without the trailing square bracket characters, and must contain an array for its value. This allows submitting multiple values with the same name, consider:

<?php
// This will NOT work correctly
$I->submitForm('#my-form', [
    'field[]' => 'value',
    'field[]' => 'another value',  // 'field[]' is already a defined key
]);

The solution is to pass an array value:

<?php
// This way both values are submitted
$I->submitForm('#my-form', [
    'field' => [
        'value',
        'another value',
    ]
]);
