Testing a POST that uses Flask-WTF validate_on_submit
You should have different configurations for your app, depending if you are local / in production / executing unit tests. One configuration you can set is
WTF_CSRF_ENABLED = False
See flask-wtforms documentation.
Using py.test and a conftest.py recommended by Delightful testing with pytest and SQLAlchemy, here's a test that confirms the added category.
def test_add_category_post(app, session):
"""Does add category post a new category?"""
TESTEMAIL = "[email protected]"
TESTUSER = "Joe Test"
user = Users.query.filter(Users.email==TESTEMAIL).first()
category = Category(name="Added Category", users_id=user.id)
form = CategoryForm(formdata=None, obj=category)
with app.test_client() as c:
with c.session_transaction() as sess:
sess['email'] = TESTEMAIL
sess['username'] = TESTUSER
sess['users_id'] = user.id
response = c.post(
'/category/add', data=form.data, follow_redirects=True)
assert response.status_code == 200
added_category = Category.query.filter(
Category.name=="Added Category").first()
assert added_category
session.delete(added_category)
session.commit()
Note that the new category is assigned to a variable and then used to create a form. The form's data is used in the post.
