Fastapi Testclient not able to send POST request using form-data - unit-testing

Question

Currently I am doing Unit Testing in Fastapi using from fastapi.testclient import TestClient
def test_login_api_returns_token(session,client):
form_data = {
"username": "mike#gmail.com",
"password": "mike"
}
response = client.post(
"/api/login",
data=form_data,
headers={"content-type": "multipart/form-data"}
# headers={"content-type": "application/x-www-form-urlencoded"}
)
result = response.json()
assert response.status_code == 200
I am supposed to get token as response which I am getting when I run the fastapi application but not able to proceed with Unit Testing with the same.
Example of postman request for the same
How do I make sure form-data is being sent from TestClient?
api/login.py
#router.post("/login")
async def user_login(form_data: OAuth2PasswordRequestForm = Depends(), session: Session = Depends(get_session)):
user = authenticated_user(form_data.username, form_data.password, session)
user = user[0]
if not user:
raise token_exception()
token_expires = timedelta(minutes=120)
token = create_access_token(username=user.username, user_id=user.id, expires_delta=token_expires)
token_exp = jwt.decode(token, SECRET, algorithms=[ALGORITHM])
return {
"status_code": status.HTTP_200_OK,
"data":{
"username": user.username,
"token": token,
"expiry": token_exp['exp'],
"user_id": user.id
}
}

Answer 1

Try set the header to Content-Type form-data like
def test_login_api_returns_token(session,client):
form_data = {
"username": "mike#gmail.com",
"password": "mike"
}
response = client.post(
"/api/login",
json=form_data,
headers={ 'Content-Type': 'application/x-www-form-urlencoded'}
)
result = response.json()
assert response.status_code == 200
