Generate Test

Create pytest tests following happy-simulator project conventions.

Project Test Patterns

Timing

• Use ConstantArrivalTimeProvider for deterministic timing in tests
• Use Instant.from_seconds() for time values
• Use Instant.Epoch for time zero, Instant.Infinity for auto-termination

File Organization

• Unit tests go in tests/unit/
• Integration tests go in tests/integration/
• File naming: test_<feature>.py
• Function naming: test_<scenario>()

Common Imports

import pytest
from happysimulator import Simulation, Event, Instant
from happysimulator.load import Source, ConstantArrivalTimeProvider

Example Test Structure

def test_example_scenario():
    """Test description explaining what behavior is verified."""
    # Arrange
    sim = Simulation(end_time=Instant.from_seconds(10))

    # Act
    sim.run()

    # Assert
    assert expected_condition

Instructions

1. Ask what functionality needs testing if not specified
2. Determine if this is a unit test or integration test
3. Generate test following the patterns above
4. Run the test with pytest tests/<path> -q to verify it passes
