Method Details

setup

@BeforeAll
static void setup()

Initializes the testing context and provisions the concurrent thread pool.

teardown

@AfterAll
static void teardown()

Gracefully shuts down the thread pool, releasing OS resources.

shouldComputeFibonacciForModerateSizeInParallel

@Test
void shouldComputeFibonacciForModerateSizeInParallel()

Scenario: Parallel execution for N=30.
