would it be possible to export num_regression as yml files ?

[12rambau]

It's not a matter of making the actual test, it's a matter of checking a problem if no arise.

I'm moving from data_regression to num_regression as the value I compare are all numbers and changes from time to time (at the 10th decimal so not relevant). the previously generated file was super easy to humanly review looking like this:

AOT: 72
B1: 238.7171666246534
B11: 948.6636123014868
B12: 750.7564658432063
B2: 320.9578522813208
B3: 415.14734055961685
B4: 426.16661204940726
B5: 604.8148600957898
B6: 1007.6004411393997
B7: 1140.246659944543
B8: 1217.7626543987888
B8A: 1200.12724981094

MSK_SNWPRB: 0
NDVI: 0.47685885754442053
QA10: 0
QA20: 0
QA60: 0

TCI_R: 43.699306780942756
WVP: 681.9462692210739

Now the output is .csv and it's barely readable (from a human standpoint):

,AOT,B1,B11,B12,B2,B3,B4,B5,B6,B7,B8,B8A,B9,MSK_CLDPRB,MSK_SNWPRB,NDVI,QA10,QA20,QA60,SCL,TCI_B,TCI_G,TCI_R,WVP

I would like to get the best of 2 worlds, the display of an easy to read yaml file (data_regression) and the comparaison of numercial value (num_regression). Do you think it could be an added feature ?

either an opt-in file format in num_regression or a special handle of numercal values in data_regresion ?

Hey @12rambau,

Hmm good point. I think this would be a nice feature to have.

either an opt-in file format in num_regression or a special handle of numercal values in data_regresion ?

I think we should focus on the purpose of the function rather, than the data format the existing functions use, so I think an option to use a different data-format in num_regression makes more sense.

Something like:

class NumericFileFormat(Enum):
    Yaml = auto()
    Csv = auto()


class NumericRegressionFixture(DataFrameRegressionFixture):
    """
    Numeric Data Regression fixture implementation used on num_regression fixture.
    """

    def check(
        self,
        data_dict: Dict[str, Any],
        basename: Optional[str] = None,
        fullpath: Optional["os.PathLike[str]"] = None,
        tolerances: Optional[Dict[str, Dict[str, float]]] = None,
        default_tolerance: Optional[Dict[str, float]] = None,
        data_index: Optional[Sequence[int]] = None,
        fill_different_shape_with_nan: bool = True,
        *,
        file_format = NumericFileFormat.Csv,
    ) -> None:

Would be happy review a PR with that change if you want to contribute.
