We have created a demo plugin to test dynamic tabs functionality. It also contains a Behat test that uses the custom Behat step included in the dynamic tabs code. This plugin can be downloaded from  https://github.com/dravek/moodle-local_dynamictabsdemo Download and install this demo plugin in the local folder of your testing instance: git clone https: //github.com/dravek/moodle-local_dynamictabsdemo.git local/dynamictabsdemo Go to Site Administration > Development > Dynamic tabs Confirm you can see two tabs labeled Tab #1 and Tab #2. Confirm that the config changes system report is shown when loading the page under Tab #1. Confirm that report pagination works. Click on the 'Filters' button and the filters form should appear. Click on Tab #2 and confirm content changes and now the report is not shown. Instead it shows a string saying 'Current time is' with your current date and time. Click again on Tab #1 and confirm it shows the config changes report again. Click again on Tab #2 and confirm that the time shown is updated with your current time (H,m,s). Click again on Tab #1 and once is loaded check that tabs can be accesed directly by URL going to <WWWROOT>/local/dynamictabsdemo/index.php#tab2 Run the automated Behat test in the plugin: mdk behat -r --tags= @local_dynamictabsdemo
