Getting TypeError: 'NoneType' object is not Callable

[bab014]

First time user. Followed the instructions, I see that benchmark is an active plugin but everytime I try and use the benchmark fixture I get that error.

What am I doing wrong?

import csv

pytest_plugins = ("benchmark",)


def csv_ingest():
    with open("./data/customers-2000000.csv") as f:
        csv_reader = csv.reader(f)
        count: int = 0
        for record in csv_reader:
            # if count == 1:
            # print(record)
            new_record = record[0:4]
            name = new_record[2].upper()


def raw_ingest():
    with open("./data/customers-2000000.csv") as f:
        count: int = 0
        for line in f:
            record = line.split(",")
            # if count == 1:
            # print(record)
            new_record = record[0:4]
            name = new_record[2].upper()


def test_csv_ingest(benchmark):
    """
    Testing speed of initial ingest
    """
    benchmark(csv_ingest())


def test_raw_ingest(benchmark):
    """
    Testing speed of initial ingest
    """
    benchmark(raw_ingest())

You're passing the result (`None`) of of your function instead of passing the function. Remove those `()`. Eg: `benchmark(csv_ingest)`
