所以我有网络应用程序,如果用户登录,他就无法注册。取而代之的是,他被重定向,并显示一条消息说他无法注册。
问题是由于某种原因我无法对其进行测试。
这是视图
@users_template.route('/signup', methods=['GET', 'POST'])
def signup():
form = RegisterationForm()
if current_user.is_authenticated and current_user.is_active: # prevent the user from seeing the register page if he's already logged in
flash('You cannot sign up while you\'re logged in')
return redirect(url_for('main.home'))
if request.method == 'POST' and form.validate_on_submit():
username = form.username.data
password = form.password.data
user = User(username=username, password=password)
if db.session.query(User).filter(User.username == username).first() is None:
current_app.logger.info('<{}> did not register before. Registering him/her now'.format(username))
db.session.add(user)
db.session.commit()
flash('Thank you for registering. Please login now')
return redirect(url_for('users.login'))
else: # the user name has been registered before
flash('You already registered')
return render_template('signup.html', form=form)
现在在我的测试模块中我有这个方法
def test_signup_page_requires_logout(self):
data_to_signup = {'username': 'mustafa1', 'password': 'mustafa1',
'confirm_password': 'mustafa1'}
data_to_login = {'username': 'mustafa1', 'password': 'mustafa1'}
# with statement preserves the request context for the current_user
with self.client:
self.client.post('/signup', data=data_to_signup)
self.client.post('/login', data=data_to_login)
response = self.client.get('/signup', follow_redirects=True)
assert b'You cannot sign up while you\'re logged in' in response.data
更令人困惑的是,这种结构适用于其他方法
def test_headquarter_after_login(self):
data_to_signup = {'username': 'mustafa1', 'password': 'mustafa1',
'confirm_password': 'mustafa1'}
data_to_login = {'username': 'mustafa1', 'password': 'mustafa1'}
with self.client:
self.client.post('/signup', data=data_to_signup)
self.client.post('/login', data=data_to_login)
response = self.client.get('/headquarter')
assert b'Headquarter page' in response.data
编辑:这是登录视图
from .. import bcrypt
@users_template.route('/login', methods=['GET', 'POST'])
def login():
form = LoginForm(request.form)
if form.validate_on_submit() and request.method == 'POST':
username = form.username.data
password = form.password.data
user = User.query.filter(User.username == username).first()
if user is not None and bcrypt.check_password_hash(user.password, password): # authenticate
login_user(user) # then log the user in
flash('You are logged in')
return redirect(url_for('main.home'))
else:
flash('Incorrect username or password') # if username is wrong, it will be caught by the error handling above
return render_template('login.html', form=form) # for a GET request
这是错误(我正在使用 py.test fyi)
assert current_user.is_active() == True
assert current_user.is_authenticated() == True
> assert b'You cannot sign up while you\'re logged in' in response.data
E AssertionError: assert b"You cannot sign up while you're logged in" in b'<!DOCTYPE html>\n<html lang="en">\n <head>\n <meta charset="utf-8">\n <meta http-equiv="X-UA-Compatible" cont...jquery/1.12.4/jquery.min.js"></script>\n <script src="/static/js/bootstrap.min.js"> </script>\n </body>\n</html>\n'

这是为了在我的所有模板中显示闪现的消息(它在我继承的“base.html”中)
{% if get_flashed_messages() %}
{% for message in get_flashed_messages() %}
<div class='container'>
<span class='alert alert-info'>
<small>{{ message }}</small>
</span>
</div>
{% endfor %}
{% endif %}
我使用闪烁的消息进行了更多测试,并且效果很好。像这个用于测试用户注册
assert b'Thank you for registering. Please login now' in response.data
