[Tests] Add coverage for PlayerLoadTask and PlayerUnloadTask event dispatch and onCancel paths - #124

Conversation
…onCancel, and SQLException paths Cover three previously untested paths in both task classes: - Anonymous CoreTask inner class event dispatch (captures the Runnable passed to scheduleSyncDelayedTask, executes it, and verifies the correct PlayerLoadEvent/PlayerUnloadEvent is fired with the right player) - onCancel when completed==true (verifies the guard prevents overwriting a successful result) - SQLException catch on Connection.close() (verifies graceful handling of try-with-resources auto-close exceptions) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013rABXAeoM6HbevheSJxjRQ

This test asserts task.getResult().join() is still true after run() triggers onCancel(), but CompletableFuture.complete() is a no-op once already completed — PlayerLoadTask.onPlayerLoadSuccessfully() already called result.complete(true) before onCancel() runs. So even if the if (!completed) guard in PlayerLoadTask.onCancel() (lines 105-109) were deleted and onPlayerLoadFail() called unconditionally, result.complete(false) would also just no-op and this assertion would still pass. The test doesn't actually exercise the guard it's meant to verify.
Suggest asserting via a spy instead, e.g.:
PlayerLoadTask spyTask = spy(task);
spyTask.run();
verify(spyTask, never()).onPlayerLoadFail();

Same structural issue as its PlayerLoadTaskTest counterpart: this asserts getResult().join() is true after onCancel() fires, but PlayerUnloadTask.onPlayerUnloadFail() (lines 123-124) just calls the already-no-op result.complete(false) once the future is completed. This can't detect a removed/inverted if (!completed) guard in PlayerUnloadTask.onCancel() (lines 90-94).
Suggest verifying via a spy that onPlayerUnloadFail() is never invoked on the already-completed task, rather than relying on the unchanged getResult() value.
