FastAPI pytest with arguments - pytest

Question

I try to test fastAPI get route with pytest and the problem is how i can pass params to client.get
main.py
#app.get('/purpose'):
async def read_purpose(name, date):
"""some logic"""
return {'ok':'ok'}
test.py
client = TestClient(app)
def test_purpose():
response = client.get("/purpose", json={"name":"test_name", "date":"01.01.2020"})
assert response.status_code = 200
My test is failed. it can not find name, and date arguments.
How i can pass this arguments to my test.
Thank you

I have same problem when writing pytest for my first FastAPI demo.
#router.post('/item', tags=['items'], response_model=ShowItem)
async def create_item(item: ItemCreate,
user_id: int,
db: Session = Depends(get_db)):
date_posted = datetime.now().date()
# owner_id = 1
item = Items(**item.dict(),
date_posted=date_posted,
owner_id=user_id)
db.add(item)
db.commit()
db.refresh(item)
return item
You can try "params" instead of "json", because you are passing isolated query parameters
def test_create_item():
# wrong
data = {'title': 'Hot Boat', 'description': 'This is a boat', 'user_id': 1}
resp = client.post('/item', json.dumps(data))
# correct
data = {'title': 'Hot Boat', 'description': 'This is a boat'}
resp = client.post('/item', json.dumps(data), params={"user_id": 2})
assert resp.status_code == 200
Then i can by pass above error.
Try this fix:
client = TestClient(app)
def test_purpose():
response = client.get("/purpose", params={"name":"test_name", "date":"01.01.2020"})
assert response.status_code = 200
