[![PyPI Version](http://img.shields.io/pypi/v/pytest-expecter.svg)](https://pypi.python.org/pypi/pytest-expecter)

## Overview

This lets you write tests (optionally using [ropez/pytest-describe](https://github.com/ropez/pytest-describe)) like this:

```python
def describe_foobar():

def it_can_pass(expect):
expect(2 + 3) == 5

def it_can_fail(expect):
expect(2 + 3) == 6
```

and get output like this:

```sh
=================================== FAILURES ===================================
_________________________ describe_foobar.it_can_fail __________________________

def it_can_fail(expect):
> expect(2 + 3) == 6
E AssertionError: Expected 6 but got 5

test_foobar.py:7: AssertionError
====================== 1 failed, 1 passed in 2.67 seconds ======================
```

```sh
pip install pytest-expecter
