Detailed Description

Helper base class for question walk-through tests.

The purpose of tests that use this base class is to simulate the entire interaction of a student making an attempt at a question. Therefore, these are not really unit tests. They would more accurately be described as integration tests. However, whether they are unit tests or not, it works well to implement them in PHPUnit.

Historically, tests like this were made because Moodle did not have anything like Behat for end-to-end testing. Even though we do now have Behat, it makes sense to keep these walk-through tests. They run massively faster than Behat tests, which gives you a much faster feedback loop while doing development. They also make it quite easy to test things like regrading the attempt after the question has been edited, which would be possible but very fiddly in Behat.

Ideally, the full set of tests for the question class of a question type would be:

A lot of unit tests for each qtype_myqtype_question class method like grade_response, is_complete_response, is_same_response, ...
Several of these walk-through tests, to test the end-to-end interaction of a student with a question, for example with different behaviours.
Just one Behat test, using question preview, to verify that everything is plugged together correctly and works when used through the UI.

What one would expect to see in one of these walk-through tests is:

// 1. Set up a question: $q.

// 2. A call to $this->start_attempt_at_question($q, ...); with the relevant options.

// 3. Some number of calls to $this->process_submission passing an array of simulated // POST data that matches what would be sent back be submitting a form that contains // the form fields that are output by rendering the question. This is like clicking // the 'Check' button in a question, or navigating to the next page in a quiz.

// 4. A call to $this->finish(); which is the equivalent of clicking // 'Submit all and finish' in the quiz.

// 5. After each of steps 2-4 above, one would expect to see a certain amount of // validation of the state of the question and how the question is rendered, // using methods like $this->check_current_state(), $this->check_current_output, etc.

The best way to work out how to write tests like this is probably to look at some examples in other question types or question behaviours.

In writing these tests, it is worth noting the following points:

a) The easiest mistake to make is at step 3. You need to ensure that your simulated post data actually matches what gets sent back when the question is submitted in the browser. Try checking it against the HTTP POST requests you see in your browser when the question is submitted. Some question types have a $q->prepare_simulated_post_data() method that can help with this.

b) In the past, tests like these used to contain even more repetitive code, and so they were re-factored to add the helper methods like start_attempt_at_question, process_submission, finish. That change had good effects, like reducing duplicate code. However, there were down-sides. The extra layers of indirection hide what is going on, which means these tests are harder to understand until you know what the helpers are doing. If you want an interesting exercise, take one of the walk-through tests, and inline all the helpers. This might be a good way to understand more about the question engine API. However, having made the everything-inlined code and learned from the process, you should then just throw it away.

c) The way check_current_output works is weird. When these tests were first written Moodle used SimpleTest for unit tests and check_current_output os written in a style that made sense there. When we moved to PHPUnit, a quick and dirty conversion was done. That was a pragmatic move at the time, and we just have to live with the result. Sorry. (And: don't copy that style for new things.)

protectedinherited

Add a mocked plugin to Moodle.

A new plugin name must be provided with a path to the plugin's root. The plugin type must already exist (or have been mocked separately).

string	$pluginname	The name of the plugin
string	$path	The path to the plugin's root

◆ add_mocked_plugintype()

advanced_testcase::add_mocked_plugintype	(	string	$plugintype,
		string	$path )

protectedinherited

Add a mocked plugintype to Moodle.

A new plugintype name must be provided with a path to the plugintype's root.

Please note that tests calling this method must be run in separate isolation mode. Please avoid using this if at all possible.

Parameters

string	$plugintype	The name of the plugintype
string	$path	The path to the plugintype's root

Parameters

string	$expectedxml	The expected XML string
string	$xml	The XML string to check

◆ assert_select_options()

question_testcase::assert_select_options	(		$expectation,
			$html )

inherited

Use this function rather than assert when checking the value of options within a select element.

Parameters

question_contains_select_expectation	$expectation	The select expectation class
string	$html	The rendered output to check against

◆ assertDebuggingCalled()

advanced_testcase::assertDebuggingCalled	(	$debugmessage = null,
		$debuglevel = null,
		$message = '' )

inherited

Assert that exactly debugging was just called once.

Discards the debugging message if successful.

Parameters

null \| string	$debugmessage	null means any
null \| string	$debuglevel	null means any
string	$message

◆ assertdebuggingcalledcount()

advanced_testcase::assertdebuggingcalledcount	(	$expectedcount,
		$debugmessages = [],
		$debuglevels = [],
		$message = '' )

inherited

Asserts how many times debugging has been called.

Parameters

int	$expectedcount	The expected number of times
array	$debugmessages	Expected debugging messages, one for each expected message.
array	$debuglevels	Expected debugging levels, one for each expected message.
string	$message

Return values

void

◆ assertDebuggingNotCalled()

advanced_testcase::assertDebuggingNotCalled ( $message = '' )

inherited

Call when no debugging() messages expected.

Parameters

string $message

◆ assertEqualsIgnoringWhitespace()

base_testcase::assertEqualsIgnoringWhitespace	(		$expected,
			$actual,
		string	$message = '' )

inherited

Assert that two Date/Time strings are equal.

The strings generated by DateTime, strtotime, date, time, etc. are generated outside of our control. From time-to-time string changes are made. One such example is from ICU 72.1 which changed the time format to include a narrow-non-breaking-space (U+202F) between the time and AM/PM.

We should not update our tests to match these changes, as it is not our code that is generating the strings and they may change again. In addition, the changes are not equal amongst all systems as they depend on the version of ICU installed.

Parameters

string	$expected
string	$actual
string	$message
