`python
import pytest
from phase import Phase

def test_phase_initialization():

phase = Phase("Warm-up", 300)
assert phase.title == "Warm-up"
assert phase.duration == 300
assert phase.state == "initial"
assert phase.time_left == 300

def test_phase_str_representation():

phase = Phase("Warm-up", 300)
expected_str = "-->Warm-up\nDuration=300\n"
assert str(phase) == expected_str

def test_phase_start():

phase = Phase("Warm-up", 300)
phase.start()
assert phase.state == "running"
assert phase.running() is True

def test_phase_pause():

phase = Phase("Warm-up", 300)
phase.start()
phase.pause()
assert phase.state == "paused"
assert phase.paused() is True

def test_phase_abort():

phase = Phase("Warm-up", 300)
phase.abort()
assert phase.state == "finished"
assert phase.finished() is True

def test_phase_tick():

phase = Phase("Warm-up", 300)
phase.start()
phase.tick(60)
assert phase.time_left == 240
assert phase.state == "running"

def test_phase_tick_to_completion():

phase = Phase("Warm-up", 300)
phase.start()
phase.tick(300)
assert phase.time_left == 0
assert phase.finished() is True

def test_phase_tick_beyond_completion():

phase = Phase("Warm-up", 300)
phase.start()
phase.tick(350)
assert phase.time_left == 0
assert phase.finished() is True

### Explanation:

• Initialization Test (test_phase_initialization): This checks that when a Phase object is created, all the attributes are correctly initialized.
• String Representation Test (test_phase_str_representation): Verifies that the __str__ method returns the expected string format.
• State Transition Tests (test_phase_start, test_phase_pause, test_phase_abort): These tests check that the start, pause, and abort methods correctly change the state of the phase.
• Running and Finished State Tests (test_phase_running, test_phase_finished): Ensure the boolean methods for checking state work correctly.
• Tick Tests (test_phase_tick, test_phase_tick_to_completion, test_phase_tick_beyond_completion): These tests validate that the tick method correctly decrements the time_left and appropriately changes the state when the timer reaches zero.

You can run these tests using pytest to ensure the correctness of the Phase class.
