WebDriver

New generation Selenium WebDriver module.

Local Testing

Selenium

To run Selenium Server you need Java as well as Chrome or Firefox browser installed.

  1. Download Selenium Standalone Server
  2. To use Chrome, install ChromeDriver. To use Firefox, install GeckoDriver.
  3. Launch the Selenium Server: java -jar selenium-server-standalone-3.xx.xxx.jar. To locate Chromedriver binary use -Dwebdriver.chrome.driver=./chromedriver option. For Geckodriver use -Dwebdriver.gecko.driver=./geckodriver.
  4. Configure this module (in acceptance.suite.yml) by setting url and browser:

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: 'http://localhost/'
         browser: chrome # 'chrome' or 'firefox'

{% endhighlight %}

Launch Selenium Server before executing tests.

{% highlight yaml %} java -jar "/path/to/selenium-server-standalone-xxx.jar"

{% endhighlight %}

ChromeDriver

To run tests in Chrome browser you may connect to ChromeDriver directly, without using Selenium Server.

  1. Install ChromeDriver.
  2. Launch ChromeDriver: chromedriver --url-base=/wd/hub
  3. Configure this module to use ChromeDriver port:

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: 'http://localhost/'
         window_size: false # disabled in ChromeDriver
         port: 9515
         browser: chrome
         capabilities:
             "goog:chromeOptions": # additional chrome options

{% endhighlight %}

Additional Chrome options can be set in goog:chromeOptions capabilities. Note that Selenium 3.8 renamed this capability from chromeOptions to goog:chromeOptions.

PhantomJS

PhantomJS is a headless browser alternative to Selenium Server that implements the WebDriver protocol. It allows you to run Selenium tests on a server without a GUI installed.

  1. Download PhantomJS
  2. Run PhantomJS in WebDriver mode: phantomjs --webdriver=4444
  3. Configure this module (in acceptance.suite.yml) by setting url and phantomjs as browser:

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: 'http://localhost/'
         browser: phantomjs

{% endhighlight %}

Since PhantomJS doesn't give you any visual feedback, it's probably a good idea to install Codeception\Extension\Recorder which gives you screenshots of how PhantomJS "sees" your pages.

Headless Selenium in Docker

Docker can ship Selenium Server with all its dependencies and browsers inside a single container. Running tests inside Docker is as easy as pulling official selenium image and starting a container with Chrome:

{% highlight yaml %} docker run --net=host selenium/standalone-chrome

{% endhighlight %}

By using --net=host we allow selenium to access local websites.

Cloud Testing

Cloud Testing services can run your WebDriver tests in the cloud. In case you want to test a local site or site behind a firewall you should use a tunnel application provided by a service.

SauceLabs

  1. Create an account at SauceLabs.com to get your username and access key
  2. In the module configuration use the format username:access_key@ondemand.saucelabs.com' for host
  3. Configure platform under capabilities to define the Operating System
  4. run a tunnel app if your site can't be accessed from Internet

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: http://mysite.com
         host: '<username>:<access key>@ondemand.saucelabs.com'
         port: 80
         browser: chrome
         capabilities:
             platform: 'Windows 10'

{% endhighlight %}

BrowserStack

  1. Create an account at BrowserStack to get your username and access key
  2. In the module configuration use the format username:access_key@hub.browserstack.com' for host
  3. Configure os and os_version under capabilities to define the operating System
  4. If your site is available only locally or via VPN you should use a tunnel app. In this case add browserstack.local capability and set it to true.

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: http://mysite.com
         host: '<username>:<access key>@hub.browserstack.com'
         port: 80
         browser: chrome
         capabilities:
             os: Windows
             os_version: 10
             browserstack.local: true # for local testing

{% endhighlight %}

TestingBot

  1. Create an account at TestingBot to get your key and secret
  2. In the module configuration use the format key:secret@hub.testingbot.com' for host
  3. Configure platform under capabilities to define the Operating System
  4. Run TestingBot Tunnel if your site can't be accessed from Internet

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: http://mysite.com
         host: '<key>:<secret>@hub.testingbot.com'
         port: 80
         browser: chrome
         capabilities:
             platform: Windows 10

{% endhighlight %}

Configuration

  • url required - Starting URL for your app.
  • browser required - Browser to launch.
  • host - Selenium server host (127.0.0.1 by default).
  • port - Selenium server port (4444 by default).
  • restart - Set to false (default) to use the same browser window for all tests, or set to true to create a new window for each test. In any case, when all tests are finished the browser window is closed.
  • start - Autostart a browser for tests. Can be disabled if browser session is started with _initializeSession inside a Helper.
  • window_size - Initial window size. Set to maximize or a dimension in the format 640x480.
  • clear_cookies - Set to false to keep cookies, or set to true (default) to delete all cookies between tests.
  • wait (default: 0 seconds) - Whenever element is required and is not on page, wait for n seconds to find it before fail.
  • capabilities - Sets Selenium desired capabilities. Should be a key-value array.
  • connection_timeout - timeout for opening a connection to remote selenium server (30 seconds by default).
  • request_timeout - timeout for a request to return something from remote selenium server (30 seconds by default).
  • pageload_timeout - amount of time to wait for a page load to complete before throwing an error (default 0 seconds).
  • http_proxy - sets http proxy server url for testing a remote server.
  • http_proxy_port - sets http proxy server port
  • debug_log_entries - how many selenium entries to print with debugWebDriverLogs or on fail (15 by default).
  • log_js_errors - Set to true to include possible JavaScript to HTML report, or set to false (default) to deactivate.

Example (acceptance.suite.yml)

{% highlight yaml %}

modules:
   enabled:
      - WebDriver:
         url: 'http://localhost/'
         browser: firefox
         window_size: 1024x768
         capabilities:
             unexpectedAlertBehaviour: 'accept'
             firefox_profile: '~/firefox-profiles/codeception-profile.zip.b64'

{% endhighlight %}

Usage

Locating Elements

Most methods in this module that operate on a DOM element (e.g. click) accept a locator as the first argument, which can be either a string or an array.

If the locator is an array, it should have a single element, with the key signifying the locator type (id, name, css, xpath, link, or class) and the value being the locator itself. This is called a "strict" locator. Examples:

  • ['id' => 'foo'] matches <div id="foo">
  • ['name' => 'foo'] matches <div name="foo">
  • ['css' => 'input[type=input][value=foo]'] matches <input type="input" value="foo">
  • ['xpath' => "//input[@type='submit'][contains(@value, 'foo')]"] matches <input type="submit" value="foobar">
  • ['link' => 'Click here'] matches <a href="google.com">Click here</a>
  • ['class' => 'foo'] matches <div class="foo">

Writing good locators can be tricky. The Mozilla team has written an excellent guide titled Writing reliable locators for Selenium and WebDriver tests.

If you prefer, you may also pass a string for the locator. This is called a "fuzzy" locator. In this case, Codeception uses a a variety of heuristics (depending on the exact method called) to determine what element you're referring to. For example, here's the heuristic used for the submitForm method:

  1. Does the locator look like an ID selector (e.g. "#foo")? If so, try to find a form matching that ID.
  2. If nothing found, check if locator looks like a CSS selector. If so, run it.
  3. If nothing found, check if locator looks like an XPath expression. If so, run it.
  4. Throw an ElementNotFound exception.

Be warned that fuzzy locators can be significantly slower than strict locators. Especially if you use Selenium WebDriver with wait (aka implicit wait) option. In the example above if you set wait to 5 seconds and use XPath string as fuzzy locator, submitForm method will wait for 5 seconds at each step. That means 5 seconds finding the form by ID, another 5 seconds finding by CSS until it finally tries to find the form by XPath). If speed is a concern, it's recommended you stick with explicitly specifying the locator type via the array syntax.

Public Properties

  • webDriver - instance of \Facebook\WebDriver\Remote\RemoteWebDriver. Can be accessed from Helper classes for complex WebDriver interactions.

{% highlight php %}

// inside Helper class $this->getModule('WebDriver')->webDriver->getKeyboard()->sendKeys('hello, webdriver');

{% endhighlight %}

Actions

_backupSession

hidden API method, expected to be used from Helper classes

Returns current WebDriver session for saving

  • return RemoteWebDriver

_capabilities

hidden API method, expected to be used from Helper classes

Change capabilities of WebDriver. Should be executed before starting a new browser session. This method expects a function to be passed which returns array or WebDriver Desired Capabilities object. Additional Chrome options (like adding extensions) can be passed as well.

{% highlight php %}

  • param $option

clearField

Clears given field which isn't empty.

{% highlight php %}

clearField('#username'); {% endhighlight %} * `param` $field #### 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. {% highlight php %} 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']); ?>

{% endhighlight %}

  • param $link
  • param $context

clickWithLeftButton

Performs click with the left mouse button on an element. If the first parameter null then the offset is relative to the actual mouse position. If the second and third parameters are given, then the mouse is moved to an offset of the element's top-left corner. Otherwise, the mouse is moved to the center of the element.

{% highlight php %}

clickWithLeftButton(['css' => '.checkout']); $I->clickWithLeftButton(null, 20, 50); $I->clickWithLeftButton(['css' => '.checkout'], 20, 50); ?>

If the second and third parameters are given, then the mouse is moved to an offset of the element's top-left corner. Otherwise, the mouse is moved to the center of the element.

{% highlight php %}

clickWithRightButton(['css' => '.checkout']); $I->clickWithRightButton(null, 20, 50); $I->clickWithRightButton(['css' => '.checkout'], 20, 50); ?>

{% endhighlight %}

{% endhighlight %}

  • param $cssOrXpath
  • param $attribute
  • return string[]

grabPageSource

Grabs current page source code.

@throws ModuleException if no page was opened.

loadSessionSnapshot

Loads cookies from a saved snapshot. Allows to reuse same session across tests without additional login.

See saveSessionSnapshot

  • param $name

makeHtmlSnapshot

Saves current page's HTML into a temprary file. Use this method in debug mode within an interactive pause to get a source code of current page.

{% highlight php %}

openNewTab

Opens a new browser tab (wherever it is possible) and switches to it.

{% highlight php %}

openNewTab(); {% endhighlight %} Tab is opened by using `window.open` javascript in a browser. Please note, that adblock can restrict creating such tabs. Can't be used with PhantomJS #### performOn Waits for element and runs a sequence of actions inside its context. Actions can be defined with array, callback, or `Codeception\Util\ActionSequence` instance. Actions as array are recommended for simple to combine "waitForElement" with assertions; `waitForElement($el)` and `see('text', $el)` can be simplified to: {% highlight php %} performOn($el, ['see' => 'text']); {% endhighlight %} List of actions can be pragmatically build using `Codeception\Util\ActionSequence`: {% highlight php %} performOn('.model', ActionSequence::build() ->see('Warning') ->see('Are you sure you want to delete this?') ->click('Yes') ); {% endhighlight %} Actions executed from array or ActionSequence will print debug output for actions, and adds an action name to exception on failure. Whenever you need to define more actions a callback can be used. A WebDriver module is passed for argument: {% highlight php %} performOn('.rememberMe', function (WebDriver $I) { $I->see('Remember me next time'); $I->seeElement('#LoginForm_rememberMe'); $I->dontSee('Login'); }); {% endhighlight %} In 3rd argument you can set number a seconds to wait for element to appear * `param` $element * `param` $actions * `param int` $timeout #### pressKey Presses the given key on the given element. To specify a character and modifier (e.g. ctrl, alt, shift, meta), pass an array for $char with the modifier as the first element and the character as the second. For special keys use key constants from WebDriverKeys class. {% highlight php %} $I->pressKey('#page','a'); // => olda $I->pressKey('#page',array('ctrl','a'),'new'); //=> new $I->pressKey('#page',array('shift','111'),'1','x'); //=> old!!!1x $I->pressKey('descendant-or-self::*[@id='page']','u'); //=> oldu $I->pressKey('#name', array('ctrl', 'a'), \Facebook\WebDriver\WebDriverKeys::DELETE); //=>'' ?>

I am Stronger than thou

` - `<script>document.createElement('strong');</script>` But will *not* be true for strings like: - `Home` - `
Home` - `` For checking the raw source code, use `seeInSource()`. * `param string` $text * `param array|string` $selector optional #### seeCheckboxIsChecked Checks that the specified checkbox is checked. {% highlight php %} seeCheckboxIsChecked('#agree'); // I suppose user agreed to terms $I->seeCheckboxIsChecked('#signup_form input[type=checkbox]'); // I suppose user agreed to terms, If there is only one checkbox in form. $I->seeCheckboxIsChecked('//form/input[@type=checkbox and @name=agree]'); ?>

For multi-select elements, or to check values of multiple elements with the same name, an array may be passed:

{% highlight php %}

seeInFormFields('.form-class', [ 'multiselect' => [ 'value1', 'value2', ], 'checkbox[]' => [ 'a checked value', 'another checked value', ], ]); ?>

{% endhighlight %}

Additionally, checkbox values can be checked with a boolean.

{% highlight php %}

seeInFormFields('#form-id', [ 'checkbox1' => true, // passes if checked 'checkbox2' => false, // passes if unchecked ]); ?>

{% endhighlight %}

Pair this with submitForm for quick testing magic.

{% highlight php %}

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

{% highlight php %}

seeOptionIsSelected('#form input[name=payment]', 'Visa'); ?>

{% endhighlight %}

  • param $selector
  • param $optionText

Selects an option in a select tag or in radio button group.

{% highlight php %}

selectOption('form select[name=account]', 'Premium'); $I->selectOption('form input[name=payment]', 'Monthly'); $I->selectOption('//form/select[@name=account]', 'Monthly'); ?>

{% endhighlight %}

Provide an array for the second argument to select multiple options:

{% highlight php %}

selectOption('Which OS do you use?', array('Windows','Linux')); ?>

{% endhighlight %}

Or provide an associative array for the second argument to specifically define which selection method should be used:

{% highlight php %}

selectOption('Which OS do you use?', array('text' => 'Windows')); // Only search by text 'Windows' $I->selectOption('Which OS do you use?', array('value' => 'windows')); // Only search by value 'windows' ?>

{% endhighlight %}

{% endhighlight %}

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

submitForm

Submits the given form on the page, optionally with the given form values. Give the form fields values as an array. Note that hidden fields can't be accessed.

Skipped fields will be filled by their values from the page. You don't need to click the 'Submit' button afterwards. This command itself triggers the request to form's action.

You can optionally specify what 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:

{% highlight php %}

submitForm('#login', [ 'login' => 'davert', 'password' => '123456' ]); // or $I->submitForm('#login', [ 'login' => 'davert', 'password' => '123456' ], 'submitButtonName'); {% endhighlight %} For example, given this sample "Sign Up" form: {% highlight html %} Login:
Password:
Do you agree to our terms?
Select pricing plan: Free Paid {% endhighlight %} You could write the following to submit it: {% highlight php %} submitForm( '#userForm', [ 'user[login]' => 'Davert', 'user[password]' => '123456', 'user[agree]' => true ], 'submitButton' ); {% endhighlight %} Note that "2" will be the submitted value for the "plan" field, as it is the selected option. Also note that this differs from PhpBrowser, in that {% highlight yaml %} 'user' => [ 'login' => 'Davert' ] {% endhighlight %} is not supported at the moment. Named array keys *must* be included in the name as above. Pair this with seeInFormFields for quick testing magic. {% highlight php %} 'value', 'field2' => 'another value', 'checkbox1' => true, // ... ]; $I->submitForm('//form[@id=my-form]', $form, 'submitButton'); // $I->amOnPage('/path/to/form-page') may be needed $I->seeInFormFields('//form[@id=my-form]', $form); ?>

{% endhighlight %}

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

{% highlight php %}

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', ] ]); ?>

{% endhighlight %}

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:

{% highlight php %}

$I->submitForm('#my-form', [ 'field[]' => 'value', 'field[]' => 'another value', // 'field[]' is already a defined key ]);

{% endhighlight %}

The solution is to pass an array value:

{% highlight php %}

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

{% endhighlight %}

The $button parameter can be either a string, an array or an instance of Facebook\WebDriver\WebDriverBy. When it is a string, the button will be found by its "name" attribute. If $button is an array then it will be treated as a strict selector and a WebDriverBy will be used verbatim.

For example, given the following HTML:

{% highlight html %}

{% endhighlight %}

$button could be any one of the following:

  • 'submitButton'
  • ['name' => 'submitButton']
  • WebDriverBy::name('submitButton')
  • param $selector
  • param $params
  • param $button

switchToIFrame

Switch to another frame on the page.

Example: {% highlight html %}

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

{% endhighlight %}

{% highlight php %}

switchToIFrame("another_frame"); # switch to parent page $I->switchToIFrame(); {% endhighlight %} * `param string|null` $name #### switchToNextTab Switches to next browser tab. An offset can be specified. {% highlight php %} switchToNextTab(); // switch to 2nd next tab $I->switchToNextTab(2); {% endhighlight %} Can't be used with PhantomJS * `param int` $offset 1 #### switchToPreviousTab Switches to previous browser tab. An offset can be specified. {% highlight php %} switchToPreviousTab(); // switch to 2nd previous tab $I->switchToPreviousTab(2); {% endhighlight %} Can't be used with PhantomJS * `param int` $offset 1 #### switchToWindow Switch to another window identified by name. The window can only be identified by name. If the $name parameter is blank, the parent window will be used. Example: {% highlight html %} {% endhighlight %} {% highlight php %} click("Open window"); # switch to another window $I->switchToWindow("another_window"); # switch to parent window $I->switchToWindow(); ?>

{% endhighlight %}

If the window has no name, match it by switching to next active tab using switchToNextTab method.

Or use native Selenium functions to get access to all opened windows:

{% highlight php %}

executeInSelenium(function (\Facebook\WebDriver\Remote\RemoteWebDriver $webdriver) { $handles=$webdriver->getWindowHandles(); $last_window = end($handles); $webdriver->switchTo()->window($last_window); }); ?>
