an asyncio testing server for mocking external services
## Features
- Fast mocks using actual network connections
- allows mocking some types of network issues
- use regular expression matching for domain, path, method, or body
- works with https requests as well (by switching them to http requests)
- works with callables
## Usage
Add routes and responses via the `aresponses.add` method:
```python
def add(
host_pattern=ANY,
path_pattern=ANY,
method_pattern=ANY,
response="",
*,
route=None,
body_pattern=ANY, m
match_querystring=False,
repeat=1
)
```
When a request is received the first matching response will be returned
and removed from the routing table. The `response` argument can be
either a string, Response, dict, or list. Use `aresponses.Response`
when you need to do something more complex.
**Note that version >=2.0 requires explicit assertions!**
```python
@pytest.mark.asyncio
async def test_simple(aresponses):
aresponses.add("google.com", "/api/v1/", "GET", response="OK")
aresponses.add('foo.com', '/', 'get', aresponses.Response(text='error', status=500))
async with aiohttp.ClientSession() as session:
async with session.get("http://google.com/api/v1/") as response:
text = await response.text()
assert text == "OK"
async with session.get("https://foo.com") as response:
text = await response.text()
assert text == "error"
aresponses.assert_plan_strictly_followed()
```
#### Assertions
In aresponses 1.x requests that didn't match a route stopped the event
loop and thus forced an exception. In aresponses >2.x it's required to
make assertions at the end of the test.
There are three assertions functions provided:
- `aresponses.assert_no_unused_routes` Raises `UnusedRouteError` if all
the routes defined were not used up.
- `aresponses.assert_called_in_order` - Raises `UnorderedRouteCallError`
if the routes weren't called in the order they were defined.
- `aresponses.assert_all_requests_matched` - Raises `NoRouteFoundError`
if any requests were made that didn't match to a route. It's likely
but not guaranteed that your code will throw an exception in this
situation before the assertion is reached.
Instead of calling these individually, **it's recommended to call
`aresponses.assert_plan_strictly_followed()` at the end of each test as
it runs all three of the above assertions.**
#### Regex and Repeat
`host_pattern`, `path_pattern`, `method_pattern` and `body_pattern` may
be either strings (exact match) or regular expressions.
The repeat argument permits a route to be used multiple times.
If you want to just blanket mock a service, without concern for how many
times its called you could set repeat to a large number and not call
`aresponses.assert_plan_strictly_followed` or
`arespones.assert_no_unused_routes`.
```python
@pytest.mark.asyncio
async def test_regex_repetition(aresponses):
aresponses.add(re.compile(r".*\.?google\.com"), response="OK", repeat=2)
async with aiohttp.ClientSession() as session:
async with session.get("http://google.com") as response:
text = await response.text()
assert text == "OK"
async with session.get("http://api.google.com") as response:
text = await response.text()
assert text == "OK"
aresponses.assert_plan_strictly_followed()
```
#### Json Responses
As a convenience, if a dict or list is passed to `response` then it will
create a json response. A `aiohttp.web_response.json_response` object
can be used for more complex situations.
```python
@pytest.mark.asyncio
async def test_json(aresponses):
aresponses.add("google.com", "/api/v1/", "GET", response={"status": "OK"})
async with aiohttp.ClientSession() as session:
async with session.get("http://google.com/api/v1/") as response:
assert {"status": "OK"} == await response.json()
aresponses.assert_plan_strictly_followed()
```
#### Custom Handler
Custom functions can be used for whatever other complex logic is
desired. In example below the handler is set to repeat infinitely
and always return 500.
```python
import math
@pytest.mark.asyncio
async def test_handler(aresponses):
def break_everything(request):
return aresponses.Response(status=500, text=str(request.url))
aresponses.add(response=break_everything, repeat=math.inf)
async with aiohttp.ClientSession() as session:
async with session.get("http://google.com/api/v1/") as response:
assert response.status == 500
```
#### Passthrough
Pass `aresponses.passthrough` into the response argument to allow a
request to bypass mocking.
```python
aresponses.add('httpstat.us', '/200', 'get', aresponses.passthrough)
```
#### Inspecting history
History of calls can be inspected via `aresponses.history` which returns
the namedTuple `RoutingLog(request, route, response)`
```python
@pytest.mark.asyncio
async def test_history(aresponses):
aresponses.add(response=aresponses.Response(text="hi"), repeat=2)
async with aiohttp.ClientSession() as session:
async with session.get("http://foo.com/b") as response:
await response.text()
async with session.get("http://bar.com/a") as response:
await response.text()
assert len(aresponses.history) == 2
assert aresponses.history[0].request.host == "foo.com"
assert aresponses.history[1].request.host == "bar.com"
assert "Route(" in repr(aresponses.history[0].route)
aresponses.assert_plan_strictly_followed()
```
#### Context manager usage
```python
import aiohttp
import pytest
import aresponses
@pytest.mark.asyncio
async def test_foo(event_loop):
async with aresponses.ResponsesMockServer(loop=event_loop) as arsps:
arsps.add('foo.com', '/', 'get', 'hi there!!')
arsps.add(arsps.ANY, '/', 'get', arsps.Response(text='hey!'))
async with aiohttp.ClientSession(loop=event_loop) as session:
async with session.get('http://foo.com') as response:
text = await response.text()
assert text == 'hi'
async with session.get('https://google.com') as response:
text = await response.text()
assert text == 'hey!'
```
#### working with [pytest-aiohttp](https://github.com/aio-libs/pytest-aiohttp)
If you need to use aresponses together with pytest-aiohttp, you should re-initialize main aresponses fixture with `loop` fixture
```python
from aresponses import ResponsesMockServer
@pytest.fixture
async def aresponses(loop):
async with ResponsesMockServer(loop=loop) as server:
yield server
```
If you're trying to use the `aiohttp_client` test fixture then you'll need to mock out the aiohttp `loop` fixture
instead:
```python
@pytest.fixture
def loop(event_loop):
"""replace aiohttp loop fixture with pytest-asyncio fixture"""
return event_loop
```
