expecting
Elegant assertions library.
This is currently a work in progress.
Installation options
pip install expecting

poetry add expecting --group dev

Usage
Expecting consists of a set of assertion objects that can be used with assert statements in a clear, readable way.
Most common assertion will be covered under a structured set of modules, following an intuitive naming schema:
import expecting

assert '2023-10-11' == expecting.string.datetime.iso8601_day()

Here, the expcting.string.datetime module introduces a handful of factory methods for asserting that the value is a
string representing a date and time format.
It's specially useful with pytest and its amazing error messages, where an assertion
failure message would look something like:
string/test_datetime.py:7 (test_iso8601_full_matches[2023/10/11 13:01:10])
'2023/10/11 13:01:10' != ~= <datetime as "%Y-%m-%dT%H:%M:%S.%f%z">

Expected :~= <datetime as "%Y-%m-%dT%H:%M:%S.%f%z">
Actual :'2023/10/11 13:01:10'
<Click to see difference>

datetime_str = '2023/10/11 13:01:10'

@pytest.mark.parametrize(
'datetime_str',
(
'2023/10/11 13:01:10',
)
)
def test_iso8601_full_matches(datetime_str: str):
> assert datetime_str == expecting.string.datetime.iso8601_full()
E assert '2023/10/11 13:01:10' == ~= <datetime as "%Y-%m-%dT%H:%M:%S.%f%z">
...

The ~= symbol prefixing the expected value is used denote this value is an "expecting object".
