python - Why doesn't Selenium's response have a sessionId? -

-

i'm trying run selenium's firefox webdriver , getting error below. can see response not have sessionid - offending line self.session_id = response['sessionid'] - don't know why. i've run in following ways , same error:

  1. cygwin, running nosetests
  2. cygwin directly
  3. windows, running nosetests
  4. windows directly

i haven't used selenium before , i'm not sure go here.

ok, first of i'd pulled out hair trying fix this. setup: python 2.7 firefox 22.0 selenium webdriver 2.33 windows xp (internet connection via proxy server)

spotted problem yet?

solution:

  • open control panel
  • internet options
  • connections
  • lan configuration
  • on page see details of proxy server, complete checkbox: "do not use proxy server local addresses". checkbox selected (as makes sense not use proxy local addresses). unfortunately, selenium webdriver appears ignore checkbox , it's value. checked or unchecked, detect proxy server , apply url's (or @ least that's did in case.)
  • click "advanced" button, , manually enter "127.0.0.1" in "exceptions" box.
  • save change.
  • re-run test in web driver, no longer see error message refers to: self.session_id = response['sessionid']

things didn't work me:

before finding solution (with aid of more experienced engineer) went through instructions here:http://docs.seleniumhq.org/docs/04_webdriver_advanced.jsp#advanceduserinteractions .. setting/changing/bypassing proxy. didn't me result looking for, though.

i looked @ this: implementing webdriverbackedselenium in python .. speaks of older version of webdriver, , suggests removing proxy settings system wide, absolute non-starter (as far i'm concerned).

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
