/**
 * Class to quickly create Behat test data using component data generators.
 *
 * There is a subclass of class for each component that wants to be able to
 * generate entities using the Behat step
 *     Given the following "entity types" exist:
 *       | test | data |
 *
 * For core entities, the entity type is like "courses" or "users" and
 * generating those is handled by behat_core_generator. For other components
 * the entity type is like "mod_quiz > User override" and that is handled by
 * behat_mod_quiz_generator defined in mod/quiz/tests/generator/behat_mod_quiz_generator.php.
 *
 * The types of entities that can be generated are described by the array returned
 * by the {@link get_generateable_entities()} method. The list in
 * {@link behat_core_generator} is a good (if complex) example.
 *
 * How things work is best explained with a few examples. All this is implemented
 * in the {@link generate_items()} method below, if you want to see every detail of
 * how it works.
 *
 * Simple example from behat_core_generator:
 * 'users' => [
 *     'datagenerator' => 'user',
 *     'required' => ['username'],
 * ],
 * The steps performed are:
 *
 * 1. 'datagenerator' => 'user' means that the word used in the method names below is 'user'.
 *
 * 2. Because 'required' is present, check the supplied data exists 'username' column is present
 *    in the supplied data table and if not display an error.
 *
 * 3. Then for each row in the table as an array $elementdata (array keys are column names)
 *    and process it as follows
 *
 * 4. (Not used in this example.)
 *
 * 5. If the method 'preprocess_user' exists, then call it to update $elementdata.
 *    (It does, in this case it sets the password to the username, if password was not given.)
 *
 * We then do one of 4 things:
 *
 * 6a. If there is a method 'process_user' we call it. (It doesn't for user,
 *     but there are other examples like process_enrol_user() in behat_core_generator.)
 *
 * 6b. (Not used in this example.)
 *
 * 6c. Else, if testing_data_generator::create_user exists, we call it with $elementdata. (it does.)
 *
 * 6d. If none of these three things work. an error is thrown.
 *
 * To understand the missing steps above, consider the example from behat_mod_quiz_generator:
 * 'group override' => [
 *      'datagenerator' => 'override',
 *      'required' => ['quiz', 'group'],
 *      'switchids' => ['quiz' => 'quiz', 'group' => 'groupid'],
 * ],
 * Processing is as above, except that:
 *
 * 1. Note 'datagenerator' is 'override' (not group_override). 'user override' maps to the
 *    same datagenerator. This works fine.
 *
 * 4. Because 'switchids' is present, human-readable data in the table gets converted to ids.
 *    They array key 'group' refers to a column which may be present in the table (it will be
 *    here because it is required, but it does not have to be in general). If that column
 *    is present and contains a value, then the method matching name like get_group_id() is
 *    called with the value from that column in the data table. You must implement this
 *    method. You can see several examples of this sort of method below.
 *
 *    If that method returns a group id, then $elementdata['group'] is unset and
 *    $elementdata['groupid'] is set to the result of the get_group_id() call. 'groupid' here
 *    because of the definition is 'switchids' => [..., 'group' => 'groupid'].
 *    If get_group_id() cannot find the group, it should throw a helpful exception.
 *
 *    Similarly, 'quiz' (the quiz name) is looked up with a call to get_quiz_id(). Here, the
 *    new array key set matches the old one removed. This is fine.
 *
 * 6b. We are in a plugin, so before checking whether testing_data_generator::create_override
 *     exists we first check whether mod_quiz_generator::create_override() exists. It does,
 *     and this is what gets called.
 *
 * This second example shows why the get_..._id methods for core entities are in this base
 * class, not in behat_core_generator. Plugins may need to look up the ids of
 * core entities.
 *
 * behat_core_generator is defined in lib/behat/classes/behat_core_generator.php
 * and for components, behat_..._generator is defined in tests/generator/behat_..._generator.php
 * inside the plugin. For example behat_mod_quiz_generator is defined in
 * mod/quiz/tests/generator/behat_mod_quiz_generator.php.
