Feature: Test log files for content
  As a developer
  I want to ensure that the log files contain the expected content

  Scenario: Check log files
    Given a mock log file with content
    When I check the log files
    Then the log files should contain the expected content
```

- steps

```py
@when("I check the log files")
def step_impl(context, log_file):
    # Get the path to the log file
    log_file_path = log_file.name

    # Open the log file for writing
    with open(log_file_path, "w") as log_file:
        log_file.write("Line 1\nLine 2\nLine 3")

    # Open the log file for reading
    with open(log_file_path, "r") as log_file:
        context.log_contents = log_file.read()
```

- steps/conftest

```py
import pytest
import tempfile

@pytest.fixture(scope="function")
def log_file():
    # Create a temporary file
    log_file = tempfile.NamedTemporaryFile(delete=False)

    # Yield the file object to the test function
    yield log_file

    # Close and delete the file after the test
    log_file.close()
    os.unlink(log_file.name)

```

- log steps

```py
import os
import tempfile
from behave import *
from unittest.mock import mock_open, patch

@given("a mock log file with content")
def step_impl(context):
    # Create a temporary file with mock content
    context.log_file = tempfile.NamedTemporaryFile(delete=False)
    context.log_file.write(b"Line 1\nLine 2\nLine 3")
    context.log_file.close()

@when("I check the log files")
def step_impl(context):
    # Get the path to the log file
    log_file_path = context.log_file.name

    # Open the log file for reading
    with open(log_file_path, "r") as log_file:
        context.log_contents = log_file.read()

@then("the log files should contain the expected content")
def step_impl(context):
    # Define the expected content
    expected_content = "Line 1\nLine 2\nLine 3"

    # Check that the log file contents match the expected content
    assert context.log_contents == expected_content
```
