Note: The last part of this test script requires the ability to run a patch against the code being tested. Create a new assignment, setting it to allow 'online text' submissions. Log in as a test student account, go to the assignment, click Add submission, type some text and click Save changes. Log back in as admin and go to the assignment. Click View all submissions. Select the student check box. From the 'With selected' select (below the table), select 'Download selected submissions'. Click 'Go' and then OK to download the file. EXPECTED: The 'Go' button should be briefly disabled (it changes colour slightly) but once the file finishes downloading, it should be re-enabled, and you can click it again to repeat the download if you like. Click the Grade button. Type a grade, like 42, and save changes. Go back to the course page and click Grades. Go to the Export tab. Click to each tab in turn and click 'Download'. EXPECTED: The download button should be briefly disabled, but once the download gets under way, it should be enabled again. Go to a forum (or create a new one) that has at least one discussion topic. From the cog in the forum main page, choose 'Export'. At the bottom of the form, click the 'Export' button. EXPECTED: The export button should be briefly disabled, but once the download starts, it should be enabled again. Apply the attached mdl-66679.patch which is supposed to turn off the double-click protection on the course settings form. Go to the course page. Click the cog icon and choose 'Edit settings'. Scroll to bottom of page and choose 'Save changes'. Watch the button carefully. EXPECTED: The 'Save changes' button does not appear disabled at any point.
