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
@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()
