Install the attached format_topics2 and format_topics3 course formats. format_topics2 contains a mobile plugin where the init function waits for 20 seconds before returning successfully. format_topics3 contains one where the init function waits for 60 seconds. These are contrived examples, but they are designed to simulate slow responses from the server or network.  When loaded successfully each of these formats displays a simple message on its course page, and nothing else. Create a course called "Topics test" using format_topics as the course format Create a course called "Topics 2 test" using format_topics2 as the course format Create a course called "Topics 3 test" using format_topics3 as the course format Enrol a user on all 3 courses.
