What's edge case testing?
Edge case just means cases that need to modify the basic algorithm to take into account uncommon but still related scenarios. Think of it like when you paint a wall (which I think is where we software devs got this term from), the basic case is just put the roller on the wall and go up and down with a slight overlap. When you get to the edge though you're still putting paint on the wall, but you're movements change and overlapping changes especially if the color on the other side of that edge is different.
It basically means they have the rework figured out, but they are making sure it is properly balanced as far as they can tell.
