learntris test suite

[4/4] basic i/o

establish a command loop and a way to exit

> q
= q : quit
: The 'q' command instructs learntris to quit.
:
: Learntris should not produce any output unless
: explicitly instructed to do so.

establish a way to print the matrix (p)

Matrix is the official term for the 10 × 22 grid of cells.

The playing area is only 10 × 20 but there are 2 extra lines above where new tetriminos form.

> q
= p : print
: The 'p' command instructs learntris to print the state
: of the matrix, the rectangular array of cells in which
: blocks can appear.
:
: The matrix is 10 cells wide and 22 cells deep, although
: the top two rows are used only for spawning new Tetraminos.
:
: At the start of the game, the matrix should be empty.
: The 'p' command should indicate empty cells with the
: '.' character.
:
: Cells should be separated by spaces.
:
: Lines should be separated by the standard end of line
: sequence on your operating system (python's "\n").

= g : given
: The 'g' command instructs learntris to read 22 lines

: characters on these lines to populate some internal
: representation of the matrix.
:
: The letter 'g' is a mnemonic for the word 'given', as
: in: "given the following matrix...."
:
: The input format should be identical to the output
: produced by the 'p' command.
:
: The letters used in the representation correspond to
: the set of colors used for blocks in the game:
:
: . = empty (black)     b = blue         c = cyan
: g = green             m = magenta      o = orange

[5/5] basic game ideas

[2/2] establish protocol to set and query the score

score register:

> ?s
0
>q
= ?s : query 's' register (score)
: The '?s' command instructs learntris to display the
: current score as a decimal number.
:
: Initially, the score should be zero.

number of lines register:

> ?n
0
>q
= ?n : query 'n' register (number of cleared lines)
: The '?n' command instructs learntris to display the
: number of lines that have been cleared.
:
: Initially, this number should be zero.

= s : step
: The 's' command instructs learntris to execute one step
: of the simulation.
:
: If the matrix contains an unbroken row of blocks, (or
: in other words, a row that contain no empty cells), then
: the 's' command should:
:
: 1. Clear the row (replacing each block with an empty cell)
: 2. Increment the 'n' register by 1.
: 3. Increment the 's' register by 100.
:
: This is only an initial approximation of the scoring
: system, but it will do for now.

[7/7] introduce the tetraminos

The I (cyan)

> I
> t
. . . .
c c c c
. . . .
. . . .
> q
= t,I : drawing and selecting the active tetramino
: At any point in time while the game is running, there
: should be a single 'active' tetramino that the player
: is able to control. Normally these are chosen somewhat
: randomly at runtime, but for automated testing, there
: needs to be some way to set the active tetramino.
:
: There are exactly seven tetraminos and they each have
: specific names used by mathematicians and players of
: video games. This one is called the I tetramino, and
: in the game, it is generally colored cyan.
:
: After issuing the 'I' command, the active tetramino
: should be the 'I' tetramino, and it should be oriented
: horizontally.
:
: In order to verify that the active tetramino is correct,
: the tests need some way to ask what it looks like. This
: is the role of the 't' command: it displays the active
: tetramino.

The O (yellow)

The O spawns in a 4 × 3 matrix:

> O
> t
y y
y y
> q
= O : The O Tetramino
: The 2x2 square is called the O tetramino, and in the game
: it should be colored yellow.
:
: Note that while the I tetramino appeared inside a 4x4
: matrix, the O tetramino's matrix is 2x2. This has to do
: with rotation, which we will deal with later.

The Z (red)

The Z and others fit in 3x3 matrices.

> Z t q
r r .
. r r
. . .
= Z : The Z Tetramino
: The Z Tetramino is colored red and inhabits a 3x3 matrix.
:
: Notice that in this test, the commands are all issued on
: a single line. This helps keep the test descriptions
: readable, and also makes it more convienient to type the
: commands interactively by hand.
:
: You do realize you can do that, right? :)
:
: Anyway, from now on, commands may be separated by either
: newlines or spaces, and your implementation may need
: to be adjusted accordingly.

The S (green)

> S t q
. g g
g g .

= S : The S Tetramino.
: The green S tetramino inhabits a 3x3 matrix. It is a mirror image of the Z.

The J (blue)

> J t q
b . .
b b b

= J : The J Tetramino
: The J tetramino is blue and inhabits a 3x3 matrix. Its default
: orientation is rotated 90 degrees counter clockwise.

The L (orange)

: The L tetramino is a mirror image of the J. It is colored orange.

: The T is is colored magenta and spawns upside down in a 3x3 matrix.

: This test case contradicts the very first one, so the only way
: to make it pass is to delete it, or replace it with something
: better. The choice is yours.

: Either way, you will need to open up testplan.org and search

NOTE How to add a new test.

• Think of a situation that needs to be tested.
• Think of the commands you would need to issue to make that situation happen.
• Write a new test that shows the expected behavior.

Here is the test format (remove the leading ‘: ’ from each line, and also the comments on the right).

 #+name: test.name                    <- must be unique!
 #+begin_src                          <- marks start of test
 # other lines with # are comments    <- comment
 > o                                  <- '>' indicates an input line
 output                               <- anything besides (#, >, :, or =)
 more output                           | is expected output.
 > q                                  <- always send the quit command!
 = my very own test                   <- this is the title for the test
 : This is where I describe the test. <- ':' indicates a line of description
 : Here's another descriptive line.    | these lines show up when a test fails.
 #+end_src                            <- marks end of test

[0/1] Ideas for more tests

• [x] Game over conditions.
• [ ] Better scoring.
• [ ] Some or all of the Super Rotation System
  • [ ] Wall Kicks
  • [ ] Floor Kicks
  • [ ] T-Spins
• [ ] The Ghost Piece (preview of where the tetramino will land)
• [ ] The Hold Piece (swap out the active tetramino)
• [ ] Test how and when the game speeds up as you progress.
• [ ] A high score system.
• [ ] Rules for when a tetramino becomes part of the matrix.

… Or come up with your own rules and make the game your own. :)
