How to restart browser after each test scenario

Question

I am testing a Chrome extension using Cucumber in conjunction with Capybara and Selenium-Webdriver.

My test is very simple:

  @chrome_extension
    @javascript
      Scenario: Test1
      Given I open a browser
      And I close the browser
      When I do nothing
      Then nothing happens

Where the steps are defined as:

require 'selenium-webdriver'

Given /^I open a browser$/ do
  visit 'http://google.com'
  STDERR.puts self
end

Given /^I close the browser$/ do
  page.driver.browser.quit
end

Given /^I do nothing$/ do

end

Given /^nothing happens$/ do

end

When I call page.driver.browser.quit, it does quit out of the browser session. But then the following error occurs:

Connection refused - connect(2) (Errno::ECONNREFUSED)

What is the proper way of restarting the browser after each scenario? I need every test to be as stateless as possible.

Thanks in advance!

Answer 1

Using Watir-webdriver, which is very similiar to selenium.

You can do this by using a hook. Do some research on hooks to get a better understanding, but in your support directory for your project, you would want to create a hook file. I am using ruby and rubymine to run my tests, so in your environment it may be different.

Your hook file might look something like this.

require 'watir-webdriver'



Before do
  @browser = Watir::Browser.new :chrome
end


After do
  @browser.close
end

Then, before each scenario is ran, it will open an instance of the browser and close the browser when the scenario is done.

Answer 2

Clear cookies and refresh browser in an After hook. For example, I use this in Watir-Webdriver

After do |scenario|
  browser.cookies.clear
  browser.refresh
end
