UI functional testing to be increased

[ddelpiano]

Starting from the latest development branch we need to increase the current test scenarios with the following:

1. Test the id= and i= logic. Ideally I would like this splitted as follow:
   1a. Test the item passed in id= takes the focus in the term info and it's selected (e.g. from here http://v2-dev2.virtualflybrain.org/org.geppetto.frontend/geppetto?id=VFB_00030624&i=VFB_00017894,VFB_00030624,VFB_00030611,VFB_00030623 you will see medulla in the term info and selected).
   1b. Test the item passed in id= that does not have visual capability takes the focus in the term info (e.g. http://v2-dev2.virtualflybrain.org/org.geppetto.frontend/geppetto?id=FBbt_00014013&i=VFB_00017894,VFB_00030611,VFB_00030623,VFB_00030624)
   1c. Test that the first id in the i= list takes the focus and it's selected (e.g. http://v2-dev2.virtualflybrain.org/org.geppetto.frontend/geppetto?i=VFB_00030624,VFB_00017894,VFB_00030611,VFB_00030623)
   1d. Same test of 1. but with neurons, these usually have download time much faster than anatomical parts and I remember I had an issue with these pre-fix, could be good to have such test as well (e.g. http://v2-dev2.virtualflybrain.org/org.geppetto.frontend/geppetto?id=VFB_00000001&i=VFB_00017894,VFB_00000001).

2. Test that the closing and reopening of the components listed is not broken (all these can be opened through the menu->Tools) :
   2a. Term Info
   2b. Stack viewer
   2c. 3d viewer
   2d. Tree browser

3. Test that minimising and restoring of the components listed:
   3a. Term Info
   3b. Stack viewer
   3c. 3d viewer
   3d. Tree browser

4. Menu component items testing:
   4a. click "Virtual Fly Brain->About" and check that the modal appears.
   4b. click "Help->F.A.Q." and check that an external link will open.

5. Focus term testing:
   5a. From a snapshot similar to this http://v2-dev2.virtualflybrain.org/org.geppetto.frontend/geppetto?id=VFB_00030624&i=VFB_00017894,VFB_00030624,VFB_00030611,VFB_00030623 , click on the Focus Term menu and check that show and hide work, close the term info and then click on "show info" that is supposed to re-open the term info, finally if the "query for" label is available run a query and check that the query builder will appear and if this gives results (I would not focus on the number of results since these can change and Robb and David will put in place more precise tests for the data itself, I would just check if there are results or not and stick to that).
   5b. Test that the icons in the term info works, so try to open and close Spotlight, Control Panel and Query builder, once done test the "Clear all" button to reset the scene.

(leave this as the last since I will introduce some changes in the tree browser today).
6. Test the tree browser:

• Open the tree browser from "Tools->Tree browser"
• Click on the arrow on the left of "adult brain" to expand the subtree.
• Click on "Adult cerebral ganglion" and check that the info will appear in the term info (currently broken, I need to check this with @Robbie1977 since it was working pre-merge and it might be possible something new has been introduced since I can see new stuff in the stack viewer).
• Click on the eye icon on the right of "Adult cerebral ganglion" and check that the item is loaded in the scene.
• Click on the color picker and check this will appear, also try to change color.
