This is pySyringe. Inversion of Control container, which helps you get proper [Dependency Injection](https://en.wikipedia.org/wiki/Dependency_injection), while still being Pythonic.

Currently pySyringe works only on Python 3.3+. Maybe later, support for older versions will be added.

## Installation

pip install pysyringe

## Usage

`python >>> import pysyringe >>> >>> class Foo: ... ... def __init__(self): ... self.bar = 42 ... >>> @pysyringe.inject(foo=Foo) ... def important_function(foo): ... return foo.bar ... >>> important_function() 42 >>> class Mock: ... def __init__(self): ... self.bar = 1 ... >>> important_function(Mock()) 1 `

As you can see testing is a lot simpler now. You don’t need as much _(hopefully none)_ mocking as you used to.

If pySyringe injects the same class twice, it doesn’t create instances twice, it simply returns previous one.

## Testing

1. Clone this repository

2. Run python setup.py develop

3. Install pytest from pip

4. Run py.test
