Answer 1

Вы тест get запрос, но на ваш взгляд, вам ответ только post:

if request.method=='POST': 
      if form.validate_on_submit()== True: 
      ... # form valid logic 
      return redirect(url_for('layout.user',page=1,sortby='normal')) 

      else: # invalid post form logic 
       return render_template('edit.html', form=form, id=id) 

return render_template('home.html) # get logic 

Если вы хотите проверить post запрос вы должны использовать пост функцию: self.client.post(url, data)

Пример

def view_code(): 
    if request.method=='POST': 
     if form.validate_on_submit()== True: 
      user.name = form.user_name 
      user.age = form.age 
      user.email = form.email 
      db.commit() 
      ... # other form valid logic 

def test_edit(self): 
    response = self.client.post('/edit/1', data={'user_name': 'admin', age='28', email='adminu@gmail.net') 
    self.assertTrue('You have been edit the profile', response.data)
