How to use the schemathesis.cli.output.default.display_statistic function in schemathesis

def test_display_statistic_empty(capsys, results_set):
    default.display_statistic(results_set)
    assert capsys.readouterr().out.split("\n")[2] == click.style("No checks were performed.", bold=True)

    single_test_statistic = models.TestResult(
        endpoint, [success, success, success, failure, failure, models.Check("different_check", models.Status.success)]
    )
    results = models.TestResultSet([single_test_statistic])
    # When test results are displayed
    default.display_statistic(results)

    # Then all check results should be properly displayed with relevant colors
    assert lines[1:3] == [
