Flask-WTF / WTForms with Unittest fails validation, but works without Unittest

When I run app normally and do login in browser, it works. But with Unittest it won't log me in .... , it returns login page again. Both "print rv.data" just prints content of login page, but it should print content of index page, which is login_required if it helps, I'm using SQLAlchemy as ORM.Anyone knows what can be problem? If any more code is needed, I will provide.I ve tried to search for similar question here , but didnt find.

#!flask/bin/pythonimport osimport unittestfrom config import basedirfrom app import app, dbfrom app.models import User,Exam,Attempt,Subjectclass TestCase(unittest.TestCase): def setUp(self): app.config['TESTING'] = True app.config['CSRF_ENABLED'] = False app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'test.db') self.app = app.test_client() db.create_all() def tearDown(self): db.session.remove() db.drop_all() def login(self, username, password): return self.app.post('/login', data=dict( username=username, password=password ), follow_redirects=True) def test_users(self): u = User(username = 'gaucan', password = 'gau') db.session.add(u) db.session.commit() rv = self.login('gaucan','gau') print rv.data rv = self.app.get('/',follow_redirects=True) print rv.dataif __name__ == '__main__': unittest.main()

I added view login function for you to see...

@app.route('/login', methods = ['GET', 'POST'])def login(): if g.user is not None and g.user.is_authenticated(): return redirect(url_for('index')) form = LoginForm() if form.validate_on_submit(): user = User.query.filter_by(username = form.username.data).first() if user is not None and form.password.data == user.password: login_user(user) flash("Logged in successfully.") return redirect(request.args.get('next') or url_for('index')) flash('Invalid password') return render_template('login.html', title='Sign In', form=form)

here is backtrace from line above form.validate_on_submit
