UItesting

UI-Testing

Creating unit tests for UI elements is inefficient as most of them do not have many functions to mock. Most of these elements display objects using tables and AddComponent methods.

So to overcome this we approach manual testing of such elements. This involves going through each and every task in the code to ensure that the elements are working as intended.

Some of the general guidelines we followed to ensure testing are:

• Images do not stretch beyond the screen size.
• Images that fill up spaces are not stretched so much that they lose clarity(eg. backgrounds), or in other words, ensure image resolution is appropriate for the case.
• Buttons should not overlap each other.
• Buttons should do what they are actually intended for.
• Images and buttons show up at the intended places.
• Ensuring additions to the game do not ruin visual aesthetics.
• Maintaining a similar theme across all elements used.

These general guidelines helped us verify that everything was working as intended.

UI-Screens

Making these guidelines the standard we got the following result for each external UI screen:

MainMenuScreen

• Background appears in place.
• Sprites of celestial bodies appear in place.
• Background & sprite remain in sync even after resolution change and minimising and maximising.
• Buttons appear in place and work as intended.

LevelSelectScreen

• Background appears in place.
• Sprites of planets (levels) appear in place.
• Background & sprite remain in sync even after resolution change and minimising and maximising.
• Unlocked planets are clikable.
• Planet description & borders comes up when mouse is hovered over them.
• To verify level lock mechanism, win & lose conditions were modified in MainGameScreen, to trigger one of these conditions, and therefore trigger one of WinningScreen, NextLevelScreen and LoosingScreen, as soon as the level was clicked. This also proved to be a time effective approach.

• Background appears in place.
• Background remain in sync even after resolution change and minimising and maximising.
