WPCLI

This module should be used in acceptance and functional tests to setup, or verify, tests pre and post conditions.
This module allows invoking any supported WP-CLI command, refer to the official site for more information.
The module will use its own version of wp-cli, not the one installed in the machine running the tests to grant isolation from local settings.
Module requirements for Codeception 4.0+
This module requires the codeception/module-cli Composer package to work when wp-browser is used with Codeception 4.0.
To install the package run:
composer require --dev codeception/module-cli:^1.0
Detecting requests coming from this module
When it runs this module will set the WPBROWSER_HOST_REQUEST environment variable.
You can detect and use that information to, as an example, use the correct database in your test site wp-config.php file:
<?php
if ( 
    // Custom header.
    isset( $_SERVER['HTTP_X_TESTING'] )
    // Custom user agent.
    || ( isset( $_SERVER['HTTP_USER_AGENT'] ) && $_SERVER['HTTP_USER_AGENT'] === 'wp-browser' )
    // The env var set by the WPClIr or WordPress modules.
    || getenv( 'WPBROWSER_HOST_REQUEST' )
) {
    // Use the test database if the request comes from a test.
    define( 'DB_NAME', 'wordpress_test' );
} else {
    // Else use the default one.
    define( 'DB_NAME', 'wordpress' );
}
Configuration
path required - the absolute, or relative, path to the WordPress root folder. This will be mapped to the --path argument of the wp-cli binary.  
throw - defaults to true to throw an exception when a wp-cli command does not return an exit status of 0; if set to false then the exit status of the commands will be returned as is.
timeout - defaults to 60 (seconds) to set each process execution timeout to a certain value; set to null, false or 0 to disable timeout completely.
Additionally the module configuration will forward any configuration parameter to wp-cli as a flag or option. In the example configuration below the allow-root flag and the some-option option will be passed to wp-cli directly and prepended to the command as global options.
Note: these extract configuration flags and options will be prepended to all commands executed by wp-cli!
Environment configuration
The wp-cli binary supports a set of enviroment variables to modify its behavior.
These environment variables can be set on the commands ran by the WPCLI module using the optional env array in the module configuration.
The example configuration below shows all of them with some example values.
Most of the times you won't need any of these, but they are there for more fine-grained control over the module operations.
The module is not validating the environment variables in any way! Those values will be evaluated by wp-cli at runtime and might generate errors if not correctly configured.
Example configuration
modules:
    enabled:
        - WPCLI
    config:
        WPCLI:
            path: /Users/Luca/Sites/wp
            throw: true
            timeout: 60
            # This will be prepended to the command, `wp --allow-root <command>`.
            allow-root: true
            # This will be prepended to the command, `wp --some-option=some-value <command>`.
            some-option: some-value
            env:
                # Any one of these, if provided, will be set as environment variable for the the cli command process. 
                # See https://make.wordpress.org/cli/handbook/config/#environment-variables for information.
                # Equivalent to `WP_CLI_STRICT_ARGS_MODE=1 wp <command>'.

                config-path: '/app/public'

                disable-auto-update: true
                # Equivalent to `WP_CLI_PACKAGES_DIR=/wp-cli/packages wp <command>'.
                packages-dir: '/wp-cli/packages'

buildFullCommand
Builds the full command to run including the PHP binary and the wp-cli boot file path.
// This method is defined in the WithWpCli trait.
  // Set the wp-cli path, `$this` is a test case.
  $this->setUpWpCli( '/var/www/html' );
  // Builds the full wp-cli command, including the `path` variable.
  $fullCommand =  $this->buildFullCommand(['core', 'version']);
  // The full command can then be used to run it with another process handler.
  $wpCliProcess = new \Symfony\Component\Process\Process($fullCommand);
  $wpCliProcess->run();
Parameters
\Codeception\Module\array/string $command - The command to run.
cli
Executes a wp-cli command targeting the test WordPress installation. minus wp. For back-compatibility purposes you can still pass the commandline as a string, but the array format is the preferred and supported method.
// Activate a plugin via wp-cli in the test WordPress site.
  $I->cli(['plugin', 'activate', 'my-plugin']);
  // Change a user password.
  $I->cli(['user', 'update', 'luca', '--user_pass=newpassword']);
Parameters

cliToArray
Returns the output of a wp-cli command as an array optionally allowing a callback to process the output. minus wp. For back-compatibility purposes you can still pass the commandline as a string, but the array format is the preferred and supported method.
// Return a list of inactive themes, like ['twentyfourteen', 'twentyfifteen'].
  $inactiveThemes = $I->cliToArray(['theme', 'list', '--status=inactive', '--field=name']);
  // Get the list of installed plugins and only keep the ones starting with "foo".
  $fooPlugins = $I->cliToArray(['plugin', 'list', '--field=name'], function($output){
  return array_filter(explode(PHP_EOL, $output), function($name){
