|
|
| S01 | A correct game that shows good practice ([SA-001]) |
|
|
| S02 | Readable behaviour that matches the assignment ([SA-001]) |
|
|
|
|
## Preconditions
|
|
|
|
The Player has started the game.
|
|
|
|
## Postconditions (Success Guarantee)
|
|
|
|
The Player has seen the final score of the game.
|
|
|
|
## Main Success Scenario
|
|
|
|
1. The Player starts a game.
|
|
2. The System shows two different accounts, A and B.
|
|
3. The Player guesses which account has more followers.
|
|
4. The System tells the Player the guess was right, adds one to the score, and shows the new score.
|
|
5. The System makes the account the Player compared against the new A and shows a new B.
|
|
6. The Player repeats from step 3 until a guess is wrong.
|
|
7. The System tells the Player the guess was wrong and shows the final score.
|
|
|
|
## Extensions / Alternative Flows
|
|
|
|
- 3a. The Player gives an answer that is not a valid choice: the System asks again; the round does not change.
|
|
- 3b. Both accounts have the same number of followers: either choice counts as right.
|
|
- 5a. No account is left that differs from the current A: the System ends the game and shows the final score.
|
|
|
|
No `<<include>>` or `<<extend>>` use cases apply.
|
|
|
|
## Special Requirements / Business Rules
|
|
|
|
- Step 2 and 5: A and B are never the same account.
|
|
- Step 3b: equal follower counts make both choices right.
|
|
|
|
## Open Issues
|
|
|
|
None.
