Selenium WebDriverException: Reached error page

问题

I am following a Django TDD tutorial at:
http://www.marinamele.com/taskbuster-django-tutorial/taskbuster-working-environment-and-start-django-project
I get the following error when running 'all_users.py' before and after I start the development server 'python manage.py runserver':

Traceback (most recent call last): File "functional_tests/all_users.py", line 15, in test_it_worked self.browser.get('http://localhost:8000') File "/Users/samgao/.virtualenvs/tb_test/lib/python3.6/site->packages/selenium/webdriver/remote/webdriver.py", line 264, in get self.execute(Command.GET, {'url': url}) File "/Users/samgao/.virtualenvs/tb_test/lib/python3.6/site->packages/selenium/webdriver/remote/webdriver.py", line 252, in execute self.error_handler.check_response(response) File "/Users/samgao/.virtualenvs/tb_test/lib/python3.6/site->packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: Reached error page: >about:neterror?e=connectionFailure&u=http%3A//localhost%3A8000/&c=UTF->8&f=regular&d=Firefox%20can%E2%80%99t%20establish%20a%20connection%20to%20the%20s>erver%20at%20localhost%3A8000.

Basically the connection to localhost cannot be established.
The settings and configurations are identical to the tutorial in the previous link.

I have been struggling with the issue for two days, and would thank you most kindly if you could provide any help.

I encountered the same problem, the final solution is: re-install again geckodriver

1. Unzip the geckodriver.zip
2. Move the file to /usr/bin directory sudo mv geckodriver /usr/bin
3. Goto /usr/bin directory cd /usr/bin,then you would need to run something like sudo chmod a+x geckodriver to mark it executable.

回答2:

this might not be your situation, but I got the same error message when running a test (same book, hehe) without having anything actually listening on the targeted port (8000, in my case). Make sure there's something listening for a request by manually opening your browser and going to localhost:8000. In my case - silly me - I didn't have the server up at all =)

I got the same error and what solved for me was changing from localhost to 127.0.0.1:

• old: self.browser.get('http://localhost:8000')

• better: self.browser.get('http://127.0.0.1:8000')

Being that this is a snapshot (around Django 1.8's time) of "Obey The Testing Goat" - perhaps the instructions there are no longer relevant. I suggest going straight to the goat's mouth and starting over!

The issue could be related to virtualenvwrapper (which is no longer necessary) or it could be related to the port/address that you were trying to access. Depending on your version of Selenium and Firefox there may be issues related to that as well.

I also followed the same tutorial and came across the same error. I noticed that I am not running the django server. The following is what helped.

python manage.py runserver
python functional_test.py
