This issue only need to be tested in 1 device. Login in master site and go to "MM Dev Testing Course > Links to capture > Activities /mod/ /view.php?id= /mod/ /view.php?f/b...=". Click the link "SCORM player, no extra params.". Check that the SCORM is opened and it plays automatically. Open the TOC (top-right, Table of contents). Check that it has selected the first incomplete SCO (each entry in the table of contents is a SCO). Check that in the table of contents it doesn't say "Preview mode". Go back to the page with links. Now click "SCORM player usign SCORM ID, no extra params.". The result should be the same as in steps 2&3. If the first incomplete SCO was the second one (the one called "The second content"), complete it now. After completing it, you can leave the SCORM player and enter again to verify that the SCO selected automatically is not the second one anymore. Go back to the page with links. Now click "SCORM player, second SCO.". Open the TOC (top-right, Table of contents). Check that it has selected the second SCO (the one called "The second content"). Check that in the table of contents it doesn't say "Preview mode". Go back to the page with links. Now click "SCORM player, second SCO, preview mode". Open the TOC (top-right, Table of contents). Check that it has selected the second SCO (the one called "The second content"). Check that in the table of contents it says "Preview mode".
