The **Object Mother Pattern** is a Python 🐍 package that simplifies and standardizes the creation of test 🧪 objects. This pattern is especially helpful in testing scenarios where you need to generate multiple instances of complex objects quickly and consistently. By providing a set of prebuilt 🛠️ object mothers, you can drop these into your existing test suite and skip the boilerplate setup yourself.

### 🎄 Real-Life Case: Christmas Detector Service

Below is an example of a real-life scenario where **Object Mother Pattern** can help simplify test date creation. We have a `ChristmasDetectorService` that checks if a given date falls within a specific Christmas holiday range. Using the [`DateMother`](https://github.com/adriamontoto/object-mother-pattern/blob/master/object_mother_pattern/mothers/dates/date/date_mother.py) class, we can easily generate dates both within and outside of this range for our tests, this ensuring that every possible scenario is covered.

```python
from datetime import date
from object_mother_pattern import DateMother


class ChristmasDetectorService:
    def __init__(self) -> None:
        self.christmas_start = date(year=2024, month=12, day=24)
        self.christmas_end = date(year=2025, month=1, day=6)

    def is_christmas(self, today: date) -> bool:
        return self.christmas_start <= today <= self.christmas_end


christmas_detector_service = ChristmasDetectorService()


def test_christmas_detector_is_christmas() -> None:
    date_mother = DateMother.create(
        start_date=date(year=2024, month=12, day=25),
        end_date=date(year=2025, month=1, day=6),
    )

    assert christmas_detector_service.is_christmas(today=date_mother)


def test_christmas_detector_is_not_christmas() -> None:
    date_mother = DateMother.out_of_range(
        start_date=date(year=2024, month=12, day=24),
        end_date=date(year=2025, month=1, day=6),
    )

    assert not christmas_detector_service.is_christmas(today=date_mother)
```

### 🧑‍🔧 Creating your own Object Mother

You can extend the functionality of this library by subclassing the
[`BaseMother`](https://github.com/adriamontoto/object-mother-pattern/blob/master/object_mother_pattern/models/base_mother.py)
class. Your custom mother must implement the `create` method to generate the
desired type.

```python
from random import randint

from object_mother_pattern.models import BaseMother


class IntegerMother(BaseMother[int]):
    @classmethod
    def create(cls, *, value: int | None = None, min: int = -100, max: int = 100) -> int:
        if value is not None:
            if not isinstance(value, int):
                raise TypeError('IntegerMother value must be an integer.')

            return value

        return randint(a=min, b=max)
```
