pytest-vcrpandas 0.0.1

Test from HTTP interactions to dataframe processed.

pytest-vcrpandas

Combine vcrpy with pandas to not only mock your HTTP interactions, but also tests your post-processing work to get a pandas DataFrame.

Usage

# test_meteo_client.py

def test_meteo_get_wind_speed(vcrpandas, client):
    start = pd.Timestamp('2018-01-01', tz='CET')
    end = pd.Timestamp('2018-02-01', tz='CET')
    with vcrpandas("meteo_get_wind_speed") as recorder:
        df = client.get_wind_speed(start, end)
        recorder(df)

# call pytest for the first time to generate samples
> pytest --vcr-record="new_episodes"

# you can now replay it:
> pytest

Behind the hood, 2 files are generated by the first run:

• a meteo_get_wind_speed.yaml, which is the reponse obtained by the first HTTP interaction.

• a meteo_get_wind_speed.pickle that serve to compare the formatting from the mocked response to the pandas DataFrame, types included.

Installation

pip install pytest-vcrpandas
