The first player wins when his item chosen is the most powerful.
- When the first player chooses scissors and the second player chooses the paper:
defmodule GameTest do
use ExUnit.Case
@stone 1
@paper 2
@scissor 3
# ...
describe "Game.play/2 when first player wins" do
test "when first player chooses scissor and second player chooses paper" do
first_player_choice = @scissor
second_player_choise = @paper
assert {:ok, match} = Game.play(first_player_choice, second_player_choise)
assert match == "First player win!!!"
end
end
end
- When the first player chooses paper and the second player chooses the stone:
defmodule GameTest do
use ExUnit.Case
@stone 1
@paper 2
@scissor 3
# ...
describe "Game.play/2 when first player wins" do
# ...
test "when first player chooses paper and second player chooses stone" do
first_player_choice = @paper
second_player_choise = @stone
assert {:ok, match} = Game.play(first_player_choice, second_player_choise)
assert match == "First player win!!!"
end
end
end
- When the first player chooses stone and the second player chooses the scissor:
defmodule GameTest do
use ExUnit.Case
@stone 1
@paper 2
@scissor 3
# ...
describe "Game.play/2 when first player wins" do
# ...
test "when first player chooses stone and second player chooses scissor" do
first_player_choice = @stone
second_player_choise = @scissor
assert {:ok, match} = Game.play(first_player_choice, second_player_choise)
assert match == "First player win!!!"
end
end
end
Let's look at the code of the tests when the game's result is
"First player win!!!".
defmodule GameTest do
use ExUnit.Case
@stone 1
@paper 2
@scissor 3
# ...
describe "Game.play/2 when first player wins" do
test "when first player chooses scissor and second player chooses paper" do
first_player_choice = @scissor
second_player_choise = @paper
assert {:ok, match} = Game.play(first_player_choice, second_player_choise)
assert match == "First player win!!!"
end
test "when first player chooses paper and second player chooses stone" do
first_player_choice = @paper
second_player_choise = @stone
assert {:ok, match} = Game.play(first_player_choice, second_player_choise)
assert match == "First player win!!!"
end
test "when first player chooses stone and second player chooses scissor" do
first_player_choice = @stone
second_player_choise = @scissor
assert {:ok, match} = Game.play(first_player_choice, second_player_choise)
assert match == "First player win!!!"
end
end
end
In the next post, we'll code our module Game following the tests when the First Player wins.
