## Quick start

### Writing tests

Using `Given`, `when`, functions as you see in the example below, you can 
determine and assert the behaviour of your `REST API`.

The `story`, `response`, `status` objects are some proxies for currently 
writing story(*inside the with Given( ... ): context*) and it's response.
and the last response after a `Given` and or `when`.

```python

import re
import sys
import json

from bddrest.authoring import Given, when, response, status


def wsgi_application(environ, start_response):
    path = environ['PATH_INFO']
    if path.endswith('/None'):
        start_response(
            '404 Not Found',
            [('Content-Type', 'text/plain;charset=utf-8')]
        )
        yield b''
    else:
        start_response(
            '200 OK',
            [('Content-Type', 'application/json;charset=utf-8')]
        )
        result = json.dumps(dict(
            foo='bar'
        ))
        yield result.encode()


with Given(
        wsgi_application,
        title='Quickstart!',
        path='/books/id: 1',
        as_='visitor') as story:

    assert status == 200
    assert status == '200 OK'
    assert 'foo' in response.json
    assert response.json['foo'] == 'bar'

    when(
        'Trying invalid book id',
        path_parameters={'id': None}
    )

    assert response.status == 404

```

### Dumping a `Story`

```python
story.dumps()
```

Produces:

```yaml
base_call:
  as_: visitor
  description: As a member I have to POST a book to the library.
  form:
    name: BDD Book
  query:
    a: b
  response:
    headers:
    - 'Content-Type: application/json;charset=utf-8'
    json:
      foo: bar
    status: 200 OK
  title: Posting a book
  path: /books/:id
  path_parameters:
    id: '1'
  verb: GET
calls:
- response:
    headers:
    - 'Content-Type: text/plain;charset=utf-8'
    status: 404 Not Found
  title: Trying invalid book id
  path_parameters:
    id: None
```

You may load the story again from this yaml with `Story.loads(yaml)`.

There are two additional methods available to dump and load to 
and from a file: `story.load(file)` and `story.dump(file)`

#### Auto Dumping

You may pass the `autodump` argument of the `Given` function to configure the 
auto-dumping:

    :param autodump: A file-like object to write dumped story.
                     Default is `None`, means autodump is disabled by default.
 

#### Auto Documentation

You may pass the `autodoc` argument of the `Given` function to configure the 
auto-documentation:

    :param autodoc: A file-like object to write documentation.
                    Default is `None`, meana autodoc is disabled by default.
    :param autodoc_format: Either ``markdown`` or ``html``. default is
                           ``markdown``.
 
### Markdown

You can use `story.document([formatter_factory=MarkdownFormatter])` to generate documentation 
in arbitrary format for example: `Markdown`.

There is also a CLI to do this: 

```bash
bddrest document < story.yml > story.md
```

    {"foo": "bar"}
    ```
    
    ## WHEN: Trying invalid book id
    
    ### Path Parameters

## Command Line Interface

After installing the project a command named `bddrest` will be available.

```bash
bddrest -h
```


### Enabling the bash autocompletion for bddrest 

Add this into your `.bashrc` and or `$VIRTUAL_ENV/bin/postactivate`.

```bash
eval "$(register-python-argcomplete bddrest)"
```
