I did a testing exercise where I had 24 hours to test the app without any requirements.
My approach to testing the site is to do Cross Browser and Mobile testing because I felt as a user I expect that the site should be compatible with all browsers and devices. I felt as a user that I would not use this app because it has so many bugs with their graphs, when I put the data in I want to turn into the graph it comes out unreadble.
I made 2 Mindmaps with my notes in it for this task a Desktop Version and a Mobile Version which you can download it by clicking on the hyperlink.
