How to send post data to flask using pytest-flask
pytest-flask provide several fixtures, including a client one. With it you can make a test function similar to this:
def test_upload(client): mimetype = 'application/json' headers = { 'Content-Type': mimetype, 'Accept': mimetype } data = { 'Data': [20.0, 30.0, 401.0, 50.0], 'Date': ['2017-08-11', '2017-08-12', '2017-08-13', '2017-08-14'], 'Day': 4 } url = '/upload/' response = client.post(url, data=json.dumps(data), headers=headers) assert response.content_type == mimetype assert response.json['Result'] == 39
While the accepted answer works, it can be simplified by passing the kwarg json into the post method instead of data
def test_upload(client): data = { 'Data': [20.0, 30.0, 401.0, 50.0], 'Date': ['2017-08-11', '2017-08-12', '2017-08-13', '2017-08-14'], 'Day': 4 } url = '/upload/' response = client.post(url, json=data) assert response.content_type == 'application/json' assert response.json['Result'] == 39
