Status: RESOLVED INCOMPLETE

(Remote Protocol :: Marionette, defect)

Description

[Titus Fortner]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.86 Safari/537.36

Steps to reproduce:

      threads, drivers = [], []

      5.times do
        threads << Thread.new do
          drivers << Selenium::WebDriver.for(browser_name, ({marionette: true} if browser_name == :marionette))
        end
      end

      threads.each do |thread|
        thread.abort_on_exception = true
        thread.join
      end

      drivers.each do |driver|
        driver.title # make any wire call
        driver.quit
      end


Actual results:

5 instances of wires and 5 browsers do open, but I only get session info back from one of them and then the code hangs:

Expected results:

5 sessions should be usable at the same time

Also, very oddly, if I already have a Marionette enabled browser open when I start the test, the test passes just fine.

That's a very old bug, and a lot has been changed since it has been reported. Lets close for now, but if that issue is still present feel free to reopen.
