Error running tests_init()

[kferris10]

I'm trying to familiarize myself with the testing workflow for animint. @cpsievert has pointed me to the testing wiki to get started, but I have been unable to run tests_init() without an error.

> library(animint)
> tests_init()

Starting phantomjs binary. To shut it down, run: 
pJS$stop()
Error:   Summary: NoSuchElement
     Detail: An element could not be located on the page using the given search parameters.
     class: org.openqa.selenium.NoSuchElementException

It also spits out some warning messages which Carson said not to worry about. If I try using Firefox, I get a different error:

> tests_init("firefox")
Undefined error in RCurl call.

Here's my session info, let me know what else I can do to help!

First, lets make sure minimal examples with RSelenium work:

• phantomjs:

Sys.which("phantomjs") # if this return an empty string you need to set your PATH to find phantomjs
library(RSelenium)
pJS <- phantom()
Sys.sleep(3)
remDr <- remoteDriver(browserName = "phantomjs")
remDr$open()
pJS$stop()

• firefox

library(RSelenium)
checkForServer()
startServer()
remDr <- remoteDriver(browserName = "firefox")
remDr$open()

[kferris10]

• phantomjs:

  Everything worked fine. I can paste the output if you want.

• firefox:

  I got this error:

  remDr$open()
  [1] "Connecting to remote server"
  Undefined error in RCurl call.
  Error in queryRD(paste0(serverURL, "/session"), "POST", qdata = toJSON(serverOpts)) :

[cpsievert]

Hmm, sometimes the server needs a few seconds to startup, so try this:

library(RSelenium)
checkForServer()
startServer()
Sys.sleep(5)
remDr <- remoteDriver(browserName = "firefox")
remDr$open()

If you still get an error, that is probably something that should be reported here (make sure to include your devtools::session_info())

As for phantomjs, could you try tests_init() again and include all the output you see? Also, try to make sure there is no Java process running in the background when you try that (RSelenium::startServer() will start Java and RSelenium::stopServer() will stop it)

[kferris10]

I've tried both of these with the version of RSelenium on CRAN (1.3.5) and on GitHub (1.3.6)

• Firefox

  Still seem to be getting the same problem. I also tried sleeping for 15 seconds and still had the same issue. I've posted the issue on the RSelenium project page here: Problem with remoteDriver() ropensci/RSelenium#49

• phantomjs

  Before I try that, I can't seem to find stopServer()

  RSelenium::startServer()
  Warning message:
  running command '"java" -jar "C:/Users/chessa015/Documents/R/win-library/3.1/RSelenium/bin/selenium-server-standalone.jar" -log "C:/Users/chessa015/Documents/R/win-library/3.1/RSelenium/bin/sellog.txt"' had status 127

  RSelenium::stopSever()
  Error: 'stopSever' is not an exported object from 'namespace:RSelenium'

[kferris10]

The ropensci people pointed out that I need to have java installed. That helped with the firefox issue. A new firefox window opens, and it tries to connect to localhost:4848. However, it cannot connect.

The good news is that I now get to the same R error as when I try to use phantomjs

tests_init("firefox")
Undefined error in RCurl call.

Starting selenium binary. To shut it down, run: 
remDr$closeWindow() 
remDr$closeServer()
Error:   Summary: NoSuchElement

[cpsievert]

Hmm, could you try changing localhost to 127.0.0.1 here?

http://superuser.com/questions/713491/why-does-localhost-not-work-in-windows-8-1-but-127-0-0-1-does

[cpsievert]

If that works, we should probably make the same changes to the shiny tests.

[kferris10]

Still getting the same issue unfortunately.

> tests_init()

Starting phantomjs binary. To shut it down, run: 
 pJS$stop()

 Error:      Summary: NoSuchElement

The traceback output

    "POST", qdata = toJSON(list(using = using, value = value)), 
    json = TRUE) 
2 remDr$findElement("xpath", "//a[@href='animint-htmltest/']") at testHelpers.R#54
1 tests_init()

I get the same error when I try to use firefox as well.

[cpsievert]

Before the Starting phantomjs binary message, you should see a message that a local file server is serving files under animint's testthat directory, for example, I see:

> tests_init()
serving the directory /Users/cpsievert/Desktop/github/local/animint/tests/testthat at http://127.0.0.1:4848 

Try running this (and show me the output):

path <- animint:::find_test_path()
path # make sure this is the full path to the testthat/ folder
animint:::run_servr(port = 4848, path) # this _should_ display a message
browseURL("http://localhost:4848/")  # if everything worked, you'll see files under testthat/ listed in your browser

[kferris10]

I don't see the serving the directory message.

Is this a Windows issue? It looks like the forward and backslashes in the path are messed up.

> path <- animint:::find_test_path()
> path # make sure this is the full path to the testthat/ folder
[1] "C:\\Users\\chessa015\\Documents\\packages\\animint/tests/testthat"
> animint:::run_servr(port = 4848, path) # this _should_ display a message

[1] 4848
> browseURL("http://localhost:4848/") 

This just opened a blank web page so it did not work.

[cpsievert]

Ah, OK, this exposed some poor programming on my part. This line should probably be file.path("tests", "testthat"), not "tests/testthat"

Would you mind making that fix and creating a pull request? The topic could be something along the lines of "get testing working on Windows".

@cpsievert I ran tests_init("firefox") and encountered following error

I got the following error and PhantomJS doesn't successfully start up since the default port 4444 of PhantomJS is possessed by other process, java in my case. see detro/ghostdriver#394

[ERROR - 2015-05-25T04:06:43.537Z] GhostDriver - main.fail - {"line":85,"sourceURL":":/ghostdriver/main.js","stack":"\tat global code (:/ghostdriver/main.js:85:56)"}

  :262 in error

Hence, instead of killing processes recorded in pid.txt, test_exit()should clean up all processes listening on the given port and default port of PhantomJS. I will give a try and present the results. @cpsievert

[cpsievert]

Hey @caijun, please try the following:

system("lsof -i :4444")
library(RSelenium)
startServer()
Sys.sleep(5)
remDr <- remoteDriver(browserName = "firefox")
remDr$open()
system("lsof -i :4444")
remDr$closeServer()
# if java is still running at this point, we should report an issue to RSelenium
system("lsof -i :4444") 

[caijun]

Hi @cpsievert , I run the codes and java is still running at on my Mac OS 10.10.3 Yosemite.

> system("lsof -i :4444")

> library(RSelenium)

> startServer()

> Sys.sleep(5)

OK, thanks. I would report that to https://github.com/ropensci/rselenium
