+ * The first row should be column names:
+ * | slot | actualquestion | variant | response |
+ * The first two of those are required. The others are optional.
+ *
+ * slot The slot
+ * actualquestion This column is optional, and is only needed if the quiz contains
+ * random questions. If so, this will let you control which acutal
+ * question gets picked when this slot is 'randomised' at the
+ * start of the attempt. If you don't specify, then one will be picked
+ * at random (which might make the reponse meaningless).
+ * variant This column is similar, and also options. It is only needed if
+ * the question that ends up in this slot returns something greater
+ * than 1 for $question->get_num_variants(). Like with actualquestion,
+ * if you specify a value here it is used the fix the 'random' choice
+ * made when the quiz is started.
+ * response The response that was submitted. How this is interpreted depends on
+ * the question type. It gets passed to
+ * {@link core_question_generator::get_simulated_post_data_for_question_attempt()
+ * and therefore to the un_summarise_response method of the question to decode.
+ *
+ * Then there should be a number of rows of data, one for each question you want to add.
+ * There is no need to supply answers to all questions. If so, other qusetions will be
+ * left unanswered.
+ *
+ * @param string $quizname the name of the quiz the user will attempt.
+ * @param string $username the username of the user that will attempt.
+ * @param TableNode $attemptinfo information about the questions to add, as above.
+ * @Given /^I attempt quiz "([^"]*)" as "([^"]*)" with the following responses:$/
