wp-browser

A WordPress specific set of extensions for Codeception., _(*1)

The package includes a class extending Codeception PhpBrowser module that adds WordPress related assertions for cest and cept tests, an extension of Codeception own Db module meant to allow for more comfortable WordPress specific database handling and testing and a class taking care of installing and loading a WordPress installation relying on WordPress automated testing suite. While working on the module I've added some methods to the Codeception\Module\Db class to implement CRUDness into it; see below the ExtendedDb class., _(*2)

Installation

To install simply require the package in the composer.json file like, _(*3)

  "require-dev":
    {
      "lucatume/wp-browser": "master@dev"
    }

and then use composer update to fetch the package.
After that follow the configuration instructions below., _(*4)

WPBrowser configuration

WPBrowser extends PHPBrowser module hence any parameter required and available to that module is required and available in WPBrowser as well.
In the suite .yml configuration file add the module among the loaded ones, _(*5)

  modules:
      enabled:
          - WPBrowser
      config:
          WPBrowser:
              url: 'http://example.local'
              adminUsername: 'root'
              adminPassword: 'root'
              adminUrl: '/wp-core/wp-admin'

and configure PHPBrowser parameters and the additional ones available to the WPBrowser module:, _(*6)

adminUsername - the site administrator username (required)
adminPassword - the site administrator login name (required)
adminUrl - the relative to the url parameter path to the administration area of the site (required)

WPWebDriver configuration

WPWebDriver extends WebDriver module hence any parameter required and available to that module is required and available in WPWebDriver as well. In the suite .yml configuration file add the module among the loaded ones, _(*7)

  modules:
      enabled:
          - WPWebDriver
      config:
          WPWebDriver:
              url: 'http://example.local'
              browser: phantomjs
              port: 4444
              window_size: '1024x768'
              adminUsername: 'root'
              adminPassword: 'root'
              adminUrl: '/wp-core/wp-admin'

and configure WPWebDriver parameters and the additional ones available to the WPWebDriver module:, _(*8)

adminUsername - the site administrator username (required)
adminPassword - the site administrator login name (required)
adminUrl - the relative to the url parameter path to the administration area of the site (required)

WPDb configuration

The module extends the Db module hence any parameter required and available by the Db module is required and available in the WPDb module as well.
In the suite .yml configuration file add the module among the loaded ones, _(*9)

  modules:
      enabled:
          - WPDb
      config:
          WPDb:
              dsn: 'mysql:host=localhost;dbname=testdb'
              user: 'root'
              password: ''
              dump: 'tests/_data/dump.sql'
              populate: true
              cleanup: true
              reconnect: true
              url: 'http://example.local'
              tablePrefix: 'wp_'

and configure Db parameters and the additional ones available to the WPDb module:, _(*10)

url - the site home url (required)
tablePrefix - allows specifying the table prefix used in the installation, defaults to wp_ (optional)

WPLoader configuration

The module wraps the configuration, installation and loading of a working headless WordPress site for testing purposes. An adaptation of WordPress automated testing suite the module exposes the suite hard-coded value as configuration parameters.
Since this module takes charge of setting up and cleaning the database used for the tests point it to a database that does not contain sensible data!
Also note that this module cannot be used together with WPDb or DB modules with the cleanup settings set to true.
In the suite .yml configuration file add the module among the loaded ones, _(*11)

  modules:
      enabled:
          - WPLoader
      config:
          WPLoader:
              wpRootFolder: "/Users/User/www/wordpress"
              dbName: "wpress-tests"
              dbHost: "localhost"
              dbUser: "root"
              dbPassword: "root"
              wpDebug: true
              dbCharset: "utf8"
              dbCollate: ""
              tablePrefix: "wptests_"
              domain: "example.org"
              adminEmail: "admin@example.com"
              title: "Test Blog"
              phpBinary: "php"
              language: ""
              configFile: ""
              plugins: ['hello.php', 'my-plugin/my-plugin.php']
              activatePlugins: ['hello.php', 'my-plugin/my-plugin.php']
              booststrapActions: ['my-first-action', 'my-second-action']

and configure it using the required parameters:, _(*12)

wpRootFolder - the absolute path to the root folder of the WordPress installation to use for testing, the ABSPATH global value.
dbNAme - the name of the database to use for the tests, will be trashed during tests so take care, will be the DB_NAME global.
dbHost - the host the database can be found at, will be the DB_HOST global.
dbUser - the database privileged user, should GRANT ALL on the database, will be the DB_USER global.
dbPassword - the password for the user, will be the DB_PASSWORD global., _(*13)

Optional parameters are available to the module to reproduce the original testing suite possibilities as closely as possible:, _(*14)
- wpDebug - bool, def. true, the WP_DEBUG global value.
- multisite - bool, def. false, if set to true will create a multisite instllation, the WP_TESTS_MULTISITE global value.
- dbCharset - string, def. utf8, the DB_CHARSET global value.
- dbCollate - string, def. ``, the DB_COLLATE global value.
- tablePrefix - string, def. wptests_, the WP_TESTS_TABLE_PREFIX value.
- domain - string, def. example.org, the root URL of the site, the WP_TESTS_DOMAIN global value.
- adminEmail - string, def. admin@example.org, the admin email, the WP_TEST_EMAIL global value.
- title - string, def. Test Blog, the blog title, the WP_TESTS_TITLE global value.
- phpBinary - string, def. php, the php bin command, the WP_PHP_BINARY global value.
- language - string, def. , the installation language, the WPLANG global value.
- configFile - string or array, def. , the path, or an array of paths, to custom config file(s) relative to the wpRootFolder folder, no leading slash needed; this is the place where custom wp_tests_options could be set.
- pluginsFolder - string, def. , the relative path to the plugins folder from the wpRootFolder if different from the wp-content/plugins default one
- plugins - array, def. ['hello.php', 'my-plugin/my-plugin.php'], a list of plugins that should be loaded before any test case runs and after mu-plugins have been loaded; these should be defined in the folder/plugin-file.php format.
- activatePlugins - array, def. ['hello.php', 'my-plugin/my-plugin.php'], a list of plugins that will be activated before any test case runs and after WordPress is fully loaded and set up; these should be defined in the folder/plugin-file.php format.
- bootstrapActions - array, def. ['my-first-action', 'my-second-action'], a list of actions that should be called after before any test case runs, after plugins have been loaded and activated.

A word of caution: right now the only way to write tests able to take advantage of the suite is to use the WP_UnitTestCase test case class; while the module will load fine and will raise no problems WP_UnitTestCase will take care of handling the database as intended and using another test case class will almost certainly result in an error if the test case defines more than one test method., _(*15)

wpcept command

The package will create a link to the bin/wpcept script file; that's an extension of Codeception own codecept CLI application to allow for a WordPress specific setup., _(*16)

bootstrap

The CLI application adds the bootstrap command argument to allow for a quick WordPress testing environment setup replacing the default bootstrap configuration created by Codeception., _(*17)

  wpcept bootstrap

The command will generate the "Unit", "Wpunit", "Functional" and "Acceptance" suites following the same pattern used by Codeception but with WordPress specific modules:, _(*18)

Unit with Asserts and helper modules
Wpunit with WPLoader and helper modules
Functional with Filesystem, WPDb, WPLoader and helper modules
Acceptance with WPBrowser, WPDb and helper modules

Please note that defautl Codeception suite bootstrapping is available using the codecept bootstrap command. The "Wpunit" suite is meant to be a middle ground between the simple unit tests of classes that are able to mock any dependency and do not rely on any WordPress defined class, method or function and those that do., _(*19)

bootstrap:pyramid

The bootstrap:pyramid command argument allows for a quick WordPress testing environment setup following the test pyramid suite organization.
The command, _(*20)

  wpcept bootstrap:pyramid

will generate the "UI", "Service" and "Unit" suites and will take care of setting up default modules and their settings for each like:, _(*21)

Unit with Asserts and UnitHelper modules
Functional with Filesystem, WPDb, WPLoader and FunctionalHelper modules
Acceptance with WPBrowser, WPDb and AcceptanceHelper modules

generate:wpunit

  wpcept generate:wpunit suite SomeClass

The command will generate a skeleton test case like, _(*23)

<?php

class SomeClassTest extends \Codeception\TestCase\WPTestCase
{
    protected function setUp()
    {
      parent::setUp();
    }

    protected function tearDown()
    {
      parent::tearDown();
    }

    // tests
    public function testMe()
    {
    }

}

generate:wprest

Generates a test case extending the \Codeception\TestCase\WPRestApiTestCase class using the, _(*24)

  wpcept generate:wprest suite SomeClass

The command will generate a skeleton test case like, _(*25)

<?php

class SomeClassTest extends \Codeception\TestCase\WPRestApiTestCase
{
    protected function setUp()
    {
      parent::setUp();
    }

    protected function tearDown()
    {
      parent::tearDown();
    }

    // tests
    public function testMe()
    {
    }

}

generate:wpajax

Generates a test case extending the \Codeception\TestCase\WPAjaxTestCase class using the, _(*26)

  wpcept generate:wpajax suite SomeClass

The command will generate a skeleton test case like, _(*27)

<?php

class SomeClassTest extends \Codeception\TestCase\WPAjaxTestCase
{
    protected function setUp()
    {
      parent::setUp();
    }

    protected function tearDown()
    {
      parent::tearDown();
    }

    // tests
    public function testMe()
    {
    }

}

generate:wpxmlrpc

Generates a test case extending the \Codeception\TestCase\WPXMLRPCTestCase class using the, _(*28)

  wpcept generate:wpxmlrpc suite SomeClass

The command will generate a skeleton test case like, _(*29)

<?php

class SomeClassTest extends \Codeception\TestCase\WPXMLRPCTestCase
{
    protected function setUp()
    {
      parent::setUp();
    }

    protected function tearDown()
    {
      parent::tearDown();
    }

    // tests
    public function testMe()
    {
    }

}

generate:wpcanonical

Generates a test case extending the \Codeception\TestCase\WPCanonicalTestCase class using the, _(*30)

  wpcept generate:wpcanonical suite SomeClass

The command will generate a skeleton test case like, _(*31)

<?php

class SomeClassTest extends \Codeception\TestCase\WPCanonicalTestCase
{
    protected function setUp()
    {
      parent::setUp();
    }

    protected function tearDown()
    {
      parent::tearDown();
    }

    // tests
    public function testMe()
    {
    }

}

Any other codecept option remains intact and available., _(*32)

generate:phpunitBootstrap

This command will generate the files required to run functional tests defined in test case classes extending the WP_UnitTestCase class.
The method will read the codeception.yml file to point PHPUnit phpunit.xml file to the tests folder and set up a phpunit-bootstrap.php file in the tests folder.
The command has the following arguments, _(*33)

suites - a comma separated list of suites the tests should run, def. functional suffix - the suffix of test classes PHPUnit should run, def. Test vendor - the path, relative to the project root folder, to the vendor folder, def. vendor, _(*34)

Each call to the command will re-generate the phpunit.xml and tests/phpunit-bootstrap.php files, changes made to the phpunit element attributes in the phpunit.xml file will be preserved across regenerations., _(*35)

ExtendedDb configuration

The module has the same configuration as the Db one and hence will not require any additional parameter beside those required/available to the Db module. In the suite .yml configuration file add the module among the loaded ones, _(*36)

  modules:
      enabled:
          - ExtendedDb
      config:
          ExtendedDb:
              dsn: 'mysql:host=localhost;dbname=testdb'
              user: 'root'
              password: ''
              dump: 'tests/_data/dump.sql'
              populate: true
              cleanup: true

and configure Db parameters as usual., _(*37)

Methods

WPBrowser module

The module adds methods that can be used in .cest and .cept methods using the same $I->doSomething syntax used in PhpBrowser.
Included methods are:, _(*38)

  // login as administrator using username and password
  public function loginAsAdmin();

  // login as user
  public function loginAs($username, $password);

  // go the plugins page
  public function amOnPluginsPage();

  // activate a plugin from the plugin page
  public function activatePlugin($pluginSlug);

  // deactivate a plugin from the plugin page
  public function deactivatePlugin($pluginSlug);

  // check that a plugin is installed and deactivated from the plugin page
  public function seePluginDeactivated($pluginSlug);

  // check that a plugin is installed and activated from the plugin page
  public function seePluginActivated($pluginSlug);

  // check that a plugin is installed from the plugin page
  public function seePluginInstalled($pluginSlug);

  // check that a plugin is not installed from the plugin page
  public function doNotSeePluginInstalled($pluginSlug);

  // check for an error admin notice
  public function seeErrorMessage($classes = '');

  // check for an updated admin notice
  public function seeMessage($classes = '');

  // check that the current page is a wp_die generated one
  public function seeWpDiePage();

  // grab all cookies whose name matches a pattern
  public function grabCookiesWithPattern($pattern);

  // grab WordPress test cookie
  public function grabWordPressTestCookie($pattern = null);

  // grab WordPress login cookie
  public function grabWordPressLoginCookie($pattern = null);

  // grab WordPrss auth cookie
  public function grabWordPressAuthCookie($pattern = null);

Methods like seePlugin... require the use of the amOnPluginsPage method before their invocation to navigate PhpBrowser to the right folder., _(*39)

WPDb module

The module extends Codeception\Module\Db and will hence act as a drop-in replacement for it. It adds an optional tablePrefix configuration parameter, defaulting to wp, and will require the same parameters as the original module.
The verbs used by the Db module are honored so dontHave removes an entry, have adds an entry, dontSee checks an entry is not in the database, see checks an entry is in the database, grab gets a value from the database or the module.
When dealing with multisite installations then the useBlog and useMainBlog methods can be used to perform any following database operation on the specified site tables if applicable; some tables are unique in a WordPress installation (e.g. users) and the command will not mess with it.
The module is meant to be a WordPress specific extension of the Db module and will hence decline the have and see methods for each WordPress table; here's a current list of all the defined methods:, _(*40)

dontHaveBlogInDatabase
dontHaveCommentInDatabase
dontHaveCommentMetaInDatabase

Handlebar templates while having many

When using one of the haveMany methods (haveManyBlogsInDatabase, haveManyCommentsInDatabase, haveManyLinksInDatabase, haveManyPostsInDatabase, haveManyTermsInDatabase, haveManyUsersInDatabase) it's possible to tap into Handlebars PHP templating capabilities to set up complex testing data.
When specifying a string value overriding the default ones the simplest replacement is the one where the {{n}} placeholder is replaced with the index of the object instance in the series:, _(*42)

$I->haveManyPostsInDatabase(3, ['post_title' => 'Post {{n}} title']);

will insert 3 posts in the database titled "Post 0 title", "Post 1 title" and "Post 2 title".
The string value will be used as a template and the n parameter will always be passed to the template; should additional template data be needed then each haveMany method allows for an additional template_data entry in the overrides array., _(*43)

$overrides = [
    'post_title' => 'Post {{n}} title {{some_string}}', 
    'template_data' => ['some_string' => 'foo']
    ];
$I->haveManyPostsInDatabase(3, $overrides);

will insert 3 posts in the database titled "Post 0 title foo", "Post 1 title foo" and "Post 2 title foo". To extend the flexibility template data allows for functions and closures to be specified: each will be called passing the index as an argument., _(*44)

$numeral = function($n){
    $numerals = ['First', 'Second', 'Third'];
    return $numerals[$n];
    };
$overrides = [
    'post_title' => '{{numeral}} post title',
    'template_data' => ['numeral' => $numeral]
    ];
$I->haveManyPostsInDatabase(3, $overrides);

will insert 3 posts in the database titled "First post title", "Second post title" and "Third post title". All of default Handlebars PHP helpers are available to use in templates; the code below is an example:, _(*45)

$numeral = function($n){
    $numerals = ['First', 'Second', 'Third'];
    return $numerals[$n];
    };
$overrides = [
    'post_title' => '{{#if n}}{{numeral}} post title{{/if}}{{#unless n}}I have index 0{{/unless}}',
    'template_data' => ['numeral' => $numeral]
    ];
$I->haveManyPostsInDatabase(3, $overrides);

will insert 3 posts in the database titled "I have index 0", "Second post title" and "Third post title"., _(*46)

ExtendedDb module

The module is an extension of the Codeception\Module\Db class implementing some methods to allow for more CRUD complete operations on the database with the methods, _(*47)

  public function dontHaveInDatabase($table, array $criteria);

  public function haveOrUpdateInDatabase($table, array $data)
