In my regexp Behat tests I would like to check that the validation error messages work. I have this scenario:
Scenario: Create a Regexp question When I am on the "Course 1" "core_question > course question bank" page logged in as teacher And I add a "Regular expression short answer" question filling the form with: | Question name | regularshortanswer-001 | | Question text | How much does this computer cost? | | Default mark | 1 | | Case sensitivity | Yes, case must match | | id_answer_0 | 799.99$ | | id_fraction_0 | 100% | | id_feedback_0 | OK. | | id_answer_1 | approximately 800$ | | id_fraction_1 | 90% | | id_feedback_1 | Almost. | Then I should see "In Answers with a grade > 0 these unescaped metacharacters are not allowed: . ^ $ * + { } \" And I set the field with xpath "//input[contains(@id, 'id_answer_1')]" to "approximately 800\$" And I click on "Save changes" "button" Then I should see "regularshortanswer-001"
Error message: "regularshortanswer-001" text was not found in the page (Behat\Mink\Exception\ExpectationException)
The reason for this error is that the scenario never presses the Save changes button on the question edit form. Do I have to issue a special command after setting a field with xpath? Be more specific in the location of the Save changes button? Or should I simply give up on this validation test?
