…nternals, and async Database init - LocalizationManager: 6 broadcastMessage tests covering both overloads (Route and Route+Map<String,String>) with loaded players, unloaded players, and no-online-players scenarios. Component overload tests use ArgumentCaptor to verify actual resolved placeholder content. - BaseItemBuilder: 9 tests across 3 nested classes covering getPlaceholdersAsConfig, parseComponent, and getReplacementCondition via reflection (DataComponentTypes prevents direct constructor testing). - Database: 1 test for non-blocking async initialization verifying custom create/update table functions execute when blockMainThreadOnStart is false.

🌐 Web query:
For the Adventure API bundled with Paper API 1.21.11, does Component#decoration(TextDecoration, boolean)return a new immutableComponent that callers must retain?
💡 Result:
Yes, the Component#decoration(TextDecoration, boolean) method in the Adventure API returns a new, immutable Component [1][2]. Because Adventure Component instances are immutable, methods that modify them—such as decoration(TextDecoration, boolean), color(), or append()—do not alter the original object [1][2]. Instead, they return a new Component instance that incorporates the requested change [1][3]. Callers must retain or use the returned value to observe the modifications [1][3].

Retain the component returned by decoration and test italic suppression.
Component is immutable. parseComponent currently discards the result of message.decoration(TextDecoration.ITALIC, false), so italic formatting remains enabled. Assign the returned component to message, and assert TextDecoration.State.FALSE; plain-text serialization cannot detect formatting.

MockBukkit 4.108.0 PlayerMock locale setLocale sendMessage API
💡 Result:
In MockBukkit, the PlayerMock class provides methods to manage a player's locale and interact with their messages for unit testing purposes. These methods align with the Bukkit/Spigot Player interface. Locale Management To set or retrieve the locale for a player, use the following methods on your PlayerMock instance: - setLocale(Locale locale): Sets the player's locale [1]. - getLocale: Returns the current locale of the player [2][1]. Example usage: player.setLocale(Locale.US); Message Interaction The PlayerMock class implements the standard Bukkit Player methods for sending messages. You can use these to verify that your code sends the expected output to the player. - sendMessage(String message): Sends a plain string message to the player [2]. - sendMessage(String... messages): Sends an array of strings to the player. - sendMessage(UUID sender, String message): Sends a message with a specified sender UUID [2]. Because PlayerMock keeps track of messages sent during tests, you can typically inspect these messages (or assert they were received) using MockBukkit's testing utilities, such as asserting that the last message sent matches a specific string. Note: MockBukkit versions are tied to specific Minecraft versions. While the API remains consistent across recent versions, ensure your project dependencies match the target Minecraft version you are testing [3].
