Codeception - Can't connect to Webdriver (Acceptance Test)

问题

I can access url and create sessions:

http://localhost:4444/wd/hub/static/resource/hub.html

but when i execute ./codecept run i get an error, but i have Selenium Server running:

[ConnectionException] Can't connect to Webdriver at http://127.0.0.1:4444/wd/hub. Please make sure that Selenium Server or PhantomJS is running.

To execute Selenium Server, i used this command:

java -Dwebdriver.gecko.driver=./geckodriver -jar "selenium-server-standalone-3.12.0.jar"

I tried too with IE and Chrome (i have the same problem too):

java -Dwebdriver.chrome.driver=./chromedriver -jar "selenium-server-standalone-3.12.0.jar"
java -Dwebdriver.ie.driver=./IEDriverServer -jar "selenium-server-standalone-3.12.0.jar"

acceptance.suite.yml

            url: 'http://localhost'
            browser: firefox

To start Selenium Server you need not require to pass/specify the WebDriver variant and you can start the Selenium Server as follows :

• Command :

  >java -jar selenium-server-standalone-3.12.0.jar
  

• Console Logs :

  C:\Utility\selenium-server-standalone>java -jar selenium-server-standalone-3.12.0.jar
  15:28:28.249 INFO [GridLauncherV3.launch] - Selenium build info: version: '3.12.0', revision: '7c6e0b3'

Update

As per the documentation at codeception.com the acceptance.suite.yml should have been as follows :

modules:
    enabled:
    - WebDriver:
       url: 'http://localhost/'
       browser: firefox
       window_size: 820x1000

Problem fixed. I was using proxy.

For future users with same problem like me, can follow the steps.

• First, check if you have proxy defined with this command:

echo %http_proxy%

• If return some result, you need set a empty proxy with this command:

set http_proxy=

You need define a proxy always you are opening a new command line.
