Make a pull request to this repo to see the checks in action 😎
Here's a sample pull request which initially failed ❌ the checks, and then passed ✅.
In it, we cover the following aspects of setting up a python project, including:
@pytest.fixture
def lowercased_df():
string_col = ['futrelle, mme. jacques heath (lily may peel)',
'backstrom, major. karl alfred (maria mathilda gustafsson)']
df_dict = {'string': string_col}
df = pd.DataFrame(df_dict)
return df
def test_extract_title(lowercased_df):
result = extract_title(lowercased_df, col='string')
assert result['title'].tolist() == ['mme', 'ms', 'mr', 'lady', 'major']
def test_extract_title_with_replacement(lowercased_df):
title_replacement = {'mme': 'mrs', 'ms': 'miss', 'lady': 'rare', 'major': 'rare'}
result = extract_title(lowercased_df, col='string', replace_dict=title_replacement)
assert result['title'].tolist() == ['mrs', 'miss', 'mr', 'rare', 'rare']
