Pattern matching helper classes designed to allow for testing of complex data structures in a readable and logical format.
Project description
Jestspectation
Pattern matching helper classes designed to allow for testing of complex data structures in a readable and logical format.
The design is inspired by the expect
system from JavaScript's Jest testing
framework.
import jestspectation as expect
assert {
"a": 1,
"b": 2,
"c": 3.0,
} == {
"a": 1,
"b": expect.Any(int),
"c": expect.FloatApprox(2.5, magnitude=0.5)
}
Installation
pip install jestspectation
Usage with Pytest
The library can be used as a pytest plugin, which can give access to much more detailed error messages when assertions fail.
You can enable it by adding the following lines to your conftest.py
pytest_plugins = ("jestspectation.pytest",)
This should result in output similar to the following
def test_goodbye():
> assert 1 == expect.Any(float)
E assert Type mismatch
E Expected any object of type float
E Received 1 (int)
