I have a CRUD football player flask app using SQL Alchemy and postgresql. I'm trying to test it with unittest and flask-testing but when I test delete and patch request on a player (based on his number), the statut returned is 200 but the player isn't deleted from the database so the test fail.
My app.py :
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI']='postgresql://postgres:password@localhost:5432/flask-sql-alchemy'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
db = SQLAlchemy(app)
modus = Modus(app)
class om_player(db.Model):
__tablename__ = "players"
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.Text)
number = db.Column(db.Integer)
age = db.Column(db.Integer)
def __init__(self, name, number, age):
self.name = name
self.number = number
self.age = age
@app.route('/joueurs/<int:number>', methods=["GET", "PATCH", "DELETE"])
def show(number):
found_player = om_player.query.filter_by(number=number).first()
if request.method == b"PATCH":
found_player.name = request.form['name']
found_player.number = request.form['number']
found_player.age = request.form['age']
db.session.add(found_player)
db.session.commit()
return redirect(url_for('show', number=request.form['number']))
if request.method == b"DELETE":
db.session.delete(found_player)
db.session.commit()
return redirect(url_for('joueurs'))
return render_template('show.html', player=found_player)
My test.py:
from app import app,db, om_player
from flask_testing import TestCase
import unittest
class BaseTestCase(TestCase):
def create_app(self):
app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://postgres:password@localhost:5432/flask-sql-alchemy'
app.config['PRESERVE_CONTEXT_ON_EXCEPTION'] = False
return app
def test_delete(self):
response = self.client.delete('/joueurs/18', follow_redirects=True)
self.assertEqual(response.status_code, 200)
self.assertNotIn(b"AMAVI", response.data)
if __name__ == '__main__':
unittest.main()
(joueurs means players in french)
When I run python test.py :
AssertionError: b'AMAVI' unexpectedly found in b'my edit.html file'
So the player with number 18 and named "AMAVI" is not deleted and I don't understand why since the delete request return 200 and my app is working fine in local server.
