# ZF1


This module allows you to run tests inside Zend Framework.
It acts just like ControllerTestCase, but with usage of Codeception syntax.

It assumes, you have standard structure with __APPLICATION_PATH__ set to './application'
and LIBRARY_PATH set to './library'. If it's not then set the appropriate path in the Config.

[Tutorial](http://codeception.com/01-27-2012/bdd-with-zend-framework.html)

## Status

* Maintainer: **davert**
* Stability: **stable**
* Contact: codecept@davert.mail.ua

## Config

* env  - environment used for testing ('testing' by default).
* config - relative path to your application config ('application/configs/application.ini' by default).
* app_path - relative path to your application folder ('application' by default).
* lib_path - relative path to your library folder ('library' by default).

## API

* client - BrowserKit client
* db - current instance of Zend_Db_Adapter
* bootstrap - current bootstrap file.

## Cleaning up

Unfortunately Zend_Db doesn't support nested transactions,
thus, for cleaning your database you should either use standard Db module or
[implement nested transactions yourself](http://blog.ekini.net/2010/03/05/zend-framework-how-to-use-nested-transactions-with-zend_db-and-mysql/).

If your database supports nested transactions (MySQL doesn't)
or you implemented them you can put all your code inside a transaction.
Use a generated helper TestHelper. Use this code inside of it.

``` php
<?php
namespace Codeception\Module;
class TestHelper extends \Codeception\Module {
     function _before($test) {
         $this->getModule('ZF1')->db->beginTransaction();
     }

     function _after($test) {
         $this->getModule('ZF1')->db->rollback();
     }
}
?>
```

This will make your functional tests run super-fast.


## 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
<?php
$els = $this->getModule('ZF1')->_findElements('.items');
$els = $this->getModule('ZF1')->_findElements(['name' => 'username']);

$editLinks = $this->getModule('ZF1')->_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
<?php
// in Helper class
public function seeResponseContains($text)
{
   $this->assertContains($text, $this->getModule('ZF1')->_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
<?php
// in Helper class
public function openCheckoutFormStep2($orderId) {
    $this->getModule('ZF1')->_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
<?php
// in Helper class
public function createUserByApi($name) {
    $userData = $this->getModule('ZF1')->_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

*hidden API method, expected to be used from Helper classes*
 
Saves page source of to a file

```php
$this->getModule('ZF1')->_savePageSource(codecept_output_dir().'page.html');
```
 * `param` $filename


### amHttpAuthenticated
 
Authenticates user for HTTP_AUTH

 * `param` $username
 * `param` $password


### amOnPage
 
Opens the page for the given relative URI.

``` php
<?php
// opens front page
$I->amOnPage('/');
// opens /register page
$I->amOnPage('/register');
```

 * `param string` $page


### amOnRoute
 
Opens web page using route name and parameters.

``` php
<?php
$I->amOnRoute('posts.create');
$I->amOnRoute('posts.show', array('id' => 34));
?>
```

 * `param` $routeName
 * `param array` $params


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

$I->attachFile('input[@type="file"]', 'prices.xls');
?>
```

 * `param` $field
 * `param` $filename


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

``` php
<?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
<?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']);
?>
```

 * `param` $link
 * `param` $context


### deleteHeader
 
Deletes the header with the passed name.  Subsequent requests
will not have the deleted header in its request.

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

 * `param string` $name the name of the header to delete.


### dontSee
 
Checks that the current page doesn't contain the text specified (case insensitive).
Give a locator as the second parameter to match a specific region.

```php
<?php
$I->dontSee('Login');                         // I can suppose user is already logged in
$I->dontSee('Sign Up','h1');                  // I can suppose it's not a signup page
$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>`

But will ignore strings like:

  - `<strong>Home</strong>`
  - `<div class="strong">Home</strong>`

For checking the raw source code, use `seeInSource()`.

 * `param string` $text
 * `param string` $selector optional

``` php
<?php
$I->dontSeeCheckboxIsChecked('#agree'); // I suppose user didn't agree to terms

?>
```

To check that an element hasn't been assigned any one of many values, an array can be passed
as the value:

?>
```

Pair this with submitForm for quick testing magic.

### 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.

 * `param` $uri
 * `param` $params


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

```

 * `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
<?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:

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

 * `param` $selector
 * `param` $params
 * `param` $button


### switchToIframe
 
Switch to iframe or frame on the page.

Example:
``` html
<iframe name="another_frame" src="http://example.com">
```

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

 * `param string` $name


### uncheckOption
 
Unticks a checkbox.

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

 * `param` $option
