Unittest Flask-App CSRF-token missing after Post-Request - unit-testing

Question

When unittesting my flask-app and sending post-requests with a Testclient I find a form.error that the CSRF token is missing.
I have been to this and to this post, also read the documentation, however I still cant get my Problem solved.
How the CSRF-Protection is created:
class Routes:
app = Flask(__name__)
app.config['SECRET_KEY'] = WebserverConfig().secret_key
CSRFProtect().init_app(__app)
The view to be tested:
#__app.route("/settings", methods=["GET", "POST"])
def settings():
form = SettingsForm()
if request.method == "POST":
if form.validate_on_submit():
Routes.__reqhandler.put_settings(form=form)
return redirect(url_for("settings"))
if form.errors != {}:
Routes.__reqhandler.error_put_settings(form=form)
data = Routes.__prepdata.prep_settings()
return render_template("settings.html", form=form, data=data)
The template which contains the form:
<form method="POST">
{{ form.hidden_tag() }}
<div class="text-center">
<h3>Einstellungen</h3>
</div>
{{ form.intervall.label }}
{{ form.intervall(id="intervall", class="form-control", placeholder=data["intervall"])}}
</form>
The fixture creating the testclient:
#pytest.fixture
def client():
app = Routes().get_app()
app.config["WTF_CSRF_METHODS"] = []
with app.test_client() as client:
yield client
The test:
def test_settings_valid_intervall(client):
res = client.post("settings", data={"intervall": "00:01:00"}, follow_redirects=True)
assert b'value="00:01:00' in res.data
When printing the data (print(res.data) an alert (created with a flash if there are errors in a form) with the info that "The CSRF token is missing" is sent. What am I missing to tell form.validate_on_submit to not check if a valid CSRF-token was passed?

I solved it by not only emptying the list of the WTF_CSRF_METHODS but also disabling CSRF within the fixture that creates the client:
app.config["WTF_CSRF_ENABLED"] = False
