General test design

Due to time restraints certain aspects of Sudoku are impractical to test manually. For example it is not practical to test what happens when the final puzzle on level 5 is completed. This would require first passing the other 64 puzzles on level 5, then completing the 65th puzzle; which would take a very long time!

In the Sudoku game levels 1-3 are a simplified form of the game and use shapes- a circle, square, star and triangle. Levels 4-5 use numbers as in traditional Sudoku. Because of this the levels 1-3 and levels 4-5 where considered as two separate equivalence partitions when testing some of the game play features. For example adding and removing symbols from the puzzle is different for the two level types. Numbers are added in levels 4 and 5 by giving squares the keyboard focus and typing a number from the keypad. Where as in levels 1 to 3, symbols are added by clicking and dragging symbols from the side bar.

However for other aspects of game play the two level types were treated as a single equivilence partition. For example the result of completing a puzzle or clicking buttons on the bottom menu bar are assumed to be the same for both level types.

Start the sudoku activity

Justification: HIG

Actions:

  1. Start the sudoku activity by clicking the icon for it in the home view.

Verify:

  • A sudoku icon (with the title sudoku) is added to the activity ring on the home screen.
  • The sudoku icon throbs to indicate the activity starting up.
  • The the sudoku activity starts properly.
  • The first puzzle for level one is loaded.

Use help manual

Justification: The help manual should be clear and easy to follow for someone who has not played the game. The vocabulary used should be understandable by a child as this is the target age group.

Actions:

  1. Click the help icon on the main menu bar.
  2. Read the main help page.
  3. Click each of the icons for the other help pages and read the contents.

Verify:

  • The main help page is displayed correctly with a title and text.
  • That clicking the icons for each page in the help manual displays the correct help page.
  • The help text is easy to read and can be understood by a first time user.
  • The icon for the page being displayed is highlighted.

Close

Actions:

  1. Click the OK button.

Verify:

  • The help closes.
  • The current sudoku puzzle is displayed in the same state it was before the help was viewed.

Changing levels

Justification: The dice button in the bottom menu should allow users to switch between levels as they please. Left click allows the user to move forward a level while right click moves back a level. Boundary cases that must be tested are what happens when the user left clicks on the dice to move forward a level when the current level is the last one, as well as right clicking the dice to move back a level when the user is already on level 1.

Next

Actions:

  1. Complete the first puzzle on level 1.
  2. Click the left mouse button on the 'dice' icon 4 times quickly.

Verify:

  • The dice rotates around to the number 5.
  • The screen displays a random puzzle from level 5.
  • The puzzle count is reset to 1.

Back to 1

Actions:

  1. Click the left button once more on the dice icon.

Verify:

  • The dice rotates and displays the number 1.
  • The puzzle count is set to 1.
  • The puzzle displayed is the same as the first puzzle completed in step one of 'next' but may have different symbols.

Back

Actions:

  1. Partially complete the 1st level 1 puzzle.
  2. Click the left button once more on the dice icon.
  3. Complete the first puzzle for level 2.
  4. Partially complete the 2nd puzzle for level 2.
  5. Click the right button on the dice.
  6. Click the right button on the dice again.
  7. Click the left button on the dice.

Verify:

  • After clicking right button on the dice the first time the dice moves back to 1 and the 1st level 1 puzzle is shown in its empty form.
  • The second right button click does nothing.
  • The next left click moves the dice to level 2, and the 1st level 2 puzzle is displayed in its empty form.

Restart puzzle

Justification: The restart puzzle icon should clear the currently displayed puzzle and restore it to it's original state. Boundary testing involves clicking the reset button while the puzzle is empty, as well as having only 1 item in it, and being 1 item from completion. Of these three the final test is least likely to discover a bug and can be skipped if time to execute the tests is limited.

Actions:

  1. Add a single item to an empty sudoku puzzle.
  2. Click the reset icon.

Verify:

  • The puzzle is returned to its empty form.

Actions:

  1. Add items to a sudoku puzzle so that it can be completed by adding 1 more item.
  2. Click the reset icon.

Verify:

  • The puzzle is returned to its empty form.

Actions:

  1. Click the reset icon while an empty form of level 1, puzzle 2 is displayed.

Verify:

  • Nothing happens.

Playing Level 1-3

Fixed squares
The squares in a puzzle which contain symbols when the puzzle is in its initial state. These symbols can not be removed or changed by the user.
Valid squares
A square in which the rules of Sudoku allow a user to place a given symbol or number in that sqare.

Moving Symbols

Justification: For this test in was initially thought that only one of the symbols needed to be tested as the functionality of the other symbols would be identical. However testing discovered that the positioning of a symbol on the side bar effected whether it passes above or below other symbols on the side bar. For that reason it was decided to test both the top and bottom symbols on the side bar.

Hover

Actions:

  1. Hover over the top symbol on the sidebar.
  2. Move to hover over the bottom symbol on the sidebar.

Verify:

  • The symbol lights up, or gives some other form of feedback to the user that indicates that the cursor is hovering over that symbol.

Click & Drag

Actions:

  1. Click and hold down the mouse button on the first symbol.
  2. Drag the symbol over the icons on the side menu bar.
  3. Drag the symbol over the icons on the bottom menu bar, and the level label.
  4. Repeat the above steps for the bottom symbol in the side bar.

Verify:

  • The symbol disapears from the sidebar and a smaller form appears attached to the cursor.
  • The symbol remains attached to the cursor as the mouse is moved.
  • The symbols is still visible and attached to the cursor when passing over the bottom bar and level label.

Adding Symbols

Justification: In general it was decided that the functionality of one symbol was the same as the functionality of the other symbols. Hence it was not neccessary to test all the symbols for every possible way of adding symbols to the puzzle.

Invalid

Justification: This test tests all the different symbols on the side bar being dragged into the various invalid positions. It is uneccessary to test all the invalid symbols being dragged into all the invalid positions.

Actions:

  1. Start with an empty puzzle on level 1.
  2. Attempt to place the 1st symbol on top of one of the icons on the bottom menu bar.
  3. Attempt to place the 2nd symbol on the menu bar in an empty space outside the puzzle.
  4. Attempt to place the 3rd symbol inside one of the FIXED invalid squares.
  5. Attempt to place the 3rd symbol inside one of the FIXED valid squares.

Verify:

  • In all three cases the symbol disapears from the cursor when the mouse is released.
  • The symbol reapears on the side menu bar.
  • Nothing else happens.

Valid Empty Square

Actions:

  1. Pick up and release a symbol inside a VALID empty square.

Verify:

  • The symbol drops from the cursor.
  • An enlarged version of the symbol appears in the empty box.
  • The background color of the square does not change.
  • The symbol reapears on the side bar.

Valid Variable Square

Actions:

  1. Pick up and release a symbol inside a VALID variable square which contains a symbol different than the one on the cursor.
  2. Pick up and release a symbol inside a VALID variable square which contains a symbol the same as the one on the cursor. (This is probably not needed)

Verify:

  • The symbol drops from the cursor.
  • An enlarged version of the symbol replaces the square in the box below.
  • The background color of the square does not change.
  • The symbol reapears on the side bar.

Invalid Variable Squares

Justification: Part of the rationale behind this test was a bug that was discovered while exploring the system. This bug resulted in filled variable squares changing to the color of fixed squares when they were highlighted because they had blocked the addition of symbol in an empty variable square.

Actions:

  1. Release a symbol inside an EMPTY square that is INVALID due to a fixed square.
  2. Release inside an EMPTY square that is INVALID due to a variable square.
  3. Release inside an EMPTY square that is INVALID due to both a variable square and fixed square.
  4. Release inside an FILLED square that is INVALID due to both a variable square and fixed square.

Verify:

  • The small symbol dissapears from the cursor.
  • It appears simultaneously back on the sidebar
  • The symbols that are already in the grid and are the reason the placement of the new symbol is INVALID are highlighted for 3 seconds.
  • The highlighted squares return to their normal state after 3 seconds.

Removing Symbols

Actions:

  1. Click on a FIXED square.
  2. Click on an EMPTY square.
  3. Click in the background of a filled VARIABLE square.

Verify:

  • Nothing happens.

Actions:

  1. Click on the symbol inside a filled VARIABLE square.

Verify:

  • The symbol inside the square dissapears.
  • The background color of the square is the same as a normal empty square.

Playing Level 4-5

Justification: The rationale behind the tests for levels 4 and 5 is similar to that for the testing of levels 1 to 3.

Hovering

Side Bar

Actions:

  1. Hover over the top symbol on sidebar.
  2. Click on the second symbol on the side bar.

Verify:

  • The symbol's dont light up.

  1. Move the cursor to the edge of the puzzle.
  2. Move the cursor into an empty square on one of the edges of the puzzle.
  3. Move the cursor into an adjacent empty square.
  4. Move the cursor into another empty square on each of the other three edges of the puzzle. (If the corners are free move to the corners)
  5. Move the cursor into a fixed square.
  6. Move it into an adjacent empty square.

Verify:

  • When the cursor enters and leaves a fixed square nothing happens to that square.
  • When the user enters an empty square the background color of the square changes to indicate that the users is hovering over it.
  • When the cursor leaves the empty square the background color returns to the original color.

Filled Variable Squares

Actions:

  1. Put a number in one of the variable squares.
  2. Give the keyboard focus to another empty square by clicking in it.
  3. Hover over the background part of that square.
  4. Hover over the number.

  2. IMMEDIATELY move the cursor into the FIXED square that caused the invalid input in the previous step.

Verify:

  • The squares in the grid that are the reason the number was INVALID are highlighted.
  • When the cursor enters the highlighted FIXED square nothing happens.
  • The highlighted squares return to their normal state after 3 seconds.

Actions:

  1. Type 2 different numbers in an EMPTY square that are INVALID, because of a filled VARIABLE square.
  2. IMMEDIATELY move the cursor into the filled variable square that caused the invalid input in the previous step.

Verify:

  • The squares in the grid that are the reason the 2 numbers are INVALID are all highlighted.
  • When the cursor enters the highlighted square the INVALID highlighting is replaced by the FOCUS highlighting. The focus highlighting remains even after the 3 secons expires.
  • Other highlighted squares return to their normal state after 3 seconds.

Extras: The above test could also be applied by clicking in the variable square and making sure the permanent focus is maintained after the 3 seconds expires. This test could also have the user move out of the square before the 3 seconds expires.
