# Testing
|
|
|
|
Sanic endpoints can be tested locally using the `test_client` object, which
|
|
depends on the additional [aiohttp](https://aiohttp.readthedocs.io/en/stable/)
|
|
library.
|
|
|
|
The `test_client` exposes `get`, `post`, `put`, `delete`, `patch`, `head` and `options` methods
|
|
for you to run against your application. A simple example (using pytest) is like follows:
|
|
|
|
```python
|
|
# Import the Sanic app, usually created with Sanic(__name__)
|
|
from external_server import app
|
|
|
|
def test_index_returns_200():
|
|
request, response = app.test_client.get('/')
|
|
assert response.status == 200
|
|
|
|
def test_index_put_not_allowed():
|
|
request, response = app.test_client.put('/')
|
|
assert response.status == 405
|
|
```
|
|
|
|
Internally, each time you call one of the `test_client` methods, the Sanic app is run at `127.0.01:42101` and
|
|
your test request is executed against your application, using `aiohttp`.
|
|
|
|
The `test_client` methods accept the following arguments and keyword arguments:
|
|
|
|
- `uri` *(default `'/'`)* A string representing the URI to test.
|
|
- `gather_request` *(default `True`)* A boolean which determines whether the
|
|
original request will be returned by the function. If set to `True`, the
|
|
return value is a tuple of `(request, response)`, if `False` only the
|
|
response is returned.
|
|
- `server_kwargs` *(default `{}`) a dict of additional arguments to pass into `app.run` before the test request is run.
|
|
- `debug` *(default `False`)* A boolean which determines whether to run the server in debug mode.
|
|
|
|
The function further takes the `*request_args` and `**request_kwargs`, which are passed directly to the aiohttp ClientSession request.
|
|
|
|
For example, to supply data to a GET request, you would do the following:
|
|
|
|
```python
|
|
def test_get_request_includes_data():
|
|
params = {'key1': 'value1', 'key2': 'value2'}
|
|
request, response = app.test_client.get('/', params=params)
|
|
assert request.args.get('key1') == 'value1'
|
|
```
|
|
|
|
And to supply data to a JSON POST request:
|
|
|
|
```python
|
|
def test_post_json_request_includes_data():
|
|
data = {'key1': 'value1', 'key2': 'value2'}
|
|
request, response = app.test_client.post('/', data=json.dumps(data))
|
|
assert request.json.get('key1') == 'value1'
|
|
```
|
|
|
|
|
|

|

the available arguments to aiohttp can be found
