Member Function Documentation

create_question()

core_question_generator::create_question	(		$qtype,
			$which = null,
			$overrides = null
	)

Create a new question.

The question is initialised using one of the examples from the appropriate question_test_helper subclass. Then, any files you want to change from the value in the base example you can override using $overrides.

Parameters

string	$qtype	the question type to create an example of.
string	$which	as for the corresponding argument of question_test_helper::get_question_form_data. null for the default one.
array | stdClass	$overrides	any fields that should be different from the base example.

Return values

stdClass

the question data.

create_question_category()

core_question_generator::create_question_category

(

$record = null

)

Create a new question category.

Parameters

array | stdClass

$record

Return values

stdClass

question_categories record.

create_question_tag()

core_question_generator::create_question_tag

(

array

$data

)

Create a tag on a question.

Parameters

array

$data

with two elements ['questionid' => 123, 'tag' => 'mytag'].

get_simulated_post_data_for_question_attempt()

core_question_generator::get_simulated_post_data_for_question_attempt	(	question_attempt	$qa,
			$responsesummary,
			$checkbutton
	)

This method can construct what the post data would be to simulate a user submitting responses to one particular question attempt.

The $responsesummary is a string representation of the response to be submitted. The exact meaning of that depends on the particular question type. These strings are passed to the un_summarise_response method of the question to decode.

Parameters

question_attempt	$qa	the question attempt for which we are generating POST data.
string	$responsesummary	a textual summary of the response, as described above.
bool	$checkbutton	if simulate a click on the check button, else simulate save. This should only be used with behaviours that have a check button.

Return values

array

the simulated post data that can be passed to $quba->process_all_actions.

get_simulated_post_data_for_questions_in_usage()

core_question_generator::get_simulated_post_data_for_questions_in_usage	(	question_usage_by_activity	$quba,
		array	$responses,
			$checkbutton
	)

This method can construct what the post data would be to simulate a user submitting responses to a number of questions within a question usage.

In the responses array, the array keys are the slot numbers for which a response will be submitted. You can submit a response to any number of responses within the usage. There is no need to do them all. The values are a string representation of the response. The exact meaning of that depends on the particular question type. These strings are passed to the un_summarise_response method of the question to decode.

Parameters

question_usage_by_activity	$quba	the question usage.
array	$responses	the resonses to submit, in the format described above.
bool	$checkbutton	if simulate a click on the check button for each question, else simulate save. This should only be used with behaviours that have a check button.

Return values

array

that can be passed to methods like $quba->process_all_actions as simulated POST data.

reset()

core_question_generator::reset

(

)

To be called from data reset code only, do not use in tests.

Return values

void

Reimplemented from component_generator_base.

set_user()

component_generator_base::set_user ( ?stdClass  $user = null )

protectedinherited

Set the current user during data generation.

This should be avoided wherever possible, but in some situations underlying code will insert data as the current user.

Parameters

stdClass

$user

setup_course_and_questions()

core_question_generator::setup_course_and_questions

(

$type = 'course'

)

Setup a course category, course, a question category, and 2 questions for testing.

Parameters

string

$type

The type of question category to create.

Return values

array

The created data objects

update_question()

core_question_generator::update_question	(		$question,
			$which = null,
			$overrides = null
	)

Update an existing question.

Parameters

stdClass	$question	the question data to update.
string	$which	as for the corresponding argument of question_test_helper::get_question_form_data. null for the default one.
array | stdClass	$overrides	any fields that should be different from the base example.

Return values

stdClass

the question data.
