Actions

_findElements

hidden API method, expected to be used from Helper classes

• api
• param mixed $locator
• return iterable

Locates element using available Codeception locator types:

• XPath
• CSS
• Strict Locator

Use it in Helpers or GroupObject or Extension classes:

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

$editLinks = $this->getModule('Mezzio')->_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

_getResponseContent

hidden API method, expected to be used from Helper classes

• api
• throws ModuleException
• return string

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)
{
   $this->assertStringContainsString($text, $this->getModule('Mezzio')->_getResponseContent(), "response contains");
}

_loadPage

hidden API method, expected to be used from Helper classes

• api
• param string $method
• param string $uri
• param array $parameters
• param array $files
• param array $server
• param ?string $content
• return void

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('Mezzio')->_loadPage('POST', '/checkout/step2', ['order' => $orderId]);
}

_request

hidden API method, expected to be used from Helper classes

• api
• see _loadPage
• param string $method
• param string $uri
• param array $parameters
• param array $files
• param array $server
• param ?string $content
• throws ExternalUrlException|ModuleException
• return ?string

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('Mezzio')->_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.

_savePageSource

hidden API method, expected to be used from Helper classes

• api
• param string $filename
• return void

Saves page source of to a file

$this->getModule('Mezzio')->_savePageSource(codecept_output_dir().'page.html');

amHttpAuthenticated

• param string $username
• param string $password
• return void

Authenticates user for HTTP_AUTH

$I->amOnPage('/');
// opens /register page
$I->amOnPage('/register');

attachFile

• param $field
• param string $filename
• return void

Attaches a file relative to the Codeception _data directory to the given file upload field.

checkOption

• param $option
• return void

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

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

click

• param string|array $link
• param $context
• return void

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

The appropriate HTTP header is added automatically: X-Requested-With: XMLHttpRequest Example:

<?php
$I->sendAjaxPostRequest('/add-task', ['task' => 'lorem ipsum']);

Some frameworks (e.g. Symfony) create field names in the form of an “array”: <input type="text" name="form[task]"> In this case you need to pass the fields like this:

<?php
$I->sendAjaxPostRequest('/add-task', ['form' => [
    'task' => 'lorem ipsum',
    'category' => 'miscellaneous',
]]);

sendAjaxRequest

startFollowingRedirects

• return void

Enables automatic redirects to be followed by the client.

<?php
$I->startFollowingRedirects();

stopFollowingRedirects

• return void

Prevents automatic redirects to be followed by the client.

<?php
$I->stopFollowingRedirects();

submitForm

• param $selector
• param array $params
• param ?string $button
• return void

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 id="userForm">
    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/>
    Subscribe to our newsletter?
    <input type="checkbox" name="user[newsletter]" value="1" checked="checked" /><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.

To uncheck the pre-checked checkbox “newsletter”, call $I->uncheckOption(['name' => 'user[newsletter]']); before, then submit the form as shown here (i.e. without the “newsletter” field in the $params array).

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',
    ]
]);

switchToIframe

• param string $name
• return void

Switch to iframe or frame on the page.

Example:

<iframe name="another_frame" src="https://example.com">

<?php
# switch to iframe
$I->switchToIframe("another_frame");

uncheckOption

• param $option
• return void

Unticks a checkbox.

<?php
$I->uncheckOption('#notify');

unsetHttpHeader

• param string $name the name of the header to unset.
• return void

Unsets a HTTP header (that was originally added by haveHttpHeader()), so that subsequent requests will not send it anymore.

Example:

<?php
$I->haveHttpHeader('X-Requested-With', 'Codeception');
$I->amOnPage('test-headers.php');
// ...
$I->unsetHeader('X-Requested-With');
$I->amOnPage('some-other-page.php');
