Method Details

setup

@BeforeAll
static void setup()

Initializes the context prior to executing validations.

teardown

@AfterAll
static void teardown()

Cleans up resources after validations complete.

shouldComputeFibonacciForModerateSize

@Test
void shouldComputeFibonacciForModerateSize()

Scenario: Computes Fibonacci for N=30.

Purpose: Executes in a reasonable timeframe (milliseconds) to serve as a fast functional verification.

shouldComputeFibonacciForLargeSizeAndDemonstrateBottleneck

@Test
void shouldComputeFibonacciForLargeSizeAndDemonstrateBottleneck()

Scenario: Computes Fibonacci for N=50.

Purpose: Demonstrates the severe bottleneck of exponential complexity. Warning: This test will block the CPU for a significant duration on a single thread. In an automated CI/CD environment, consider adding @Disabled to prevent pipeline freezing.
