Create request context ​

With test_request_context we can change the contents of flask.request used in the application.

python
from flask import request

For GET requests (access data with request.args):

python
with app.test_request_context('/', query_string={'name': 'Taro'}):
    assert request.path == '/'
    assert request.method == 'GET'
    assert request.args['name'] == 'Taro'

For POST requests (access data with request.form):

python
with app.test_request_context('/', method='POST', data={'name': 'Taro'}):
    assert request.path == '/'
    assert request.method == 'POST'
    assert request.form['name'] == 'Taro'

For POST requests using application/json header (access data with request.json):

python
with app.test_request_context('/', method='POST', json={'name': 'Taro'}):
    assert request.path == '/'
    assert request.method == 'POST'
    assert request.json['name'] == 'Taro'
