Currency System's Test Plan

In order to ensure the currency system and the game run safely, we will validate the following:

Unit testing

Testing Metrics

Component	Code Coverage (Sonarcloud)
CurrencyComponent	100%
CurrencyFactoryComponent	87.5%
CurrencyManagerComponent	100%
CollectibleComponent	90.6%
GameStateService	100%

CurrencyComponentTest

• Verify that the getters getType and getValue for currency value and type return the correct results.

CurrencyManagerComponentTest

• Ensure currency types and their quantities are tracked and updated correctly.
• Ensure methods addCurrencyAmount and subtractCurrencyAmount increment and decrement correctly.
• Verify that method addCurrencyEntity adds currency entities to currencyList correctly and does not add the same entity twice.
• Ensure method getCurrencyList returns correct list.
• Ensure method collectCurrency successfully increments counter and triggers to update UI.
• Ensure method canAffordAndSpendCurrency correctly deducts currencies by the given cost map and returns true if the player can afford, otherwise does not deduct anything and returns false.
• Ensure method dropCurrency updates the player’s balance and triggers UI changes when enemies drop currencies.
• Ensure method refundCurrency refunds the correct portion of the original cost based on the refund rate.

CollectibleComponentTest

• Verify that currencies can only be collected when the user clicks within the defined radius, and not otherwise.
• Tested via unit tests and visual validation during gameplay.

CurrencyFactoryTest

• Ensure methods createCurrency works with expected values and positions.

GameStateSystemTest

• Verify that the getStars, setStars, and updateStars methods all work as intended.

Behavioral testing

Counter updates

• Ensure the currency counter increments correctly as currencies are collected.
• Tested via visual validation during gameplay.

UI updates

• Confirm that the UI reflects the updated counter in real time as currencies are collected.
  • Includes in-game currencies on the main game screen, as well as the meta currency (stars) on the main menu screen.
• Tested via visual validation during gameplay.
