How to close browser at the end of watir test suite?

Using ruby's watir to test a web app leaves the browser open at the end. Some advice online is that to make a true unit test you should open and close the browser on every test (in the teardown call), but that is slow and pointless. Or alternatively they do something like this:

 def self.suite
   s = super
   def s.afterClass
     # Close browser
   end

   def s.run(*args)
     super
     afterClass
   end
   s
 end

but that causes the summary output to no longer display (Something like "100 tests, 100 assertions, 0 failures, 0 errors" should still display).

How can I just get ruby or watir to close the browser at the end of my tests?

When you want to use one and only browser during your RSpec specs, then you can use :suite hooks instead of :all which would create and close browser within each example group:

RSpec.configure do |config|
  config.before :suite do
    $browser = Watir::Browser.new
  end

  config.after :suite do
    $browser.close if $browser
  end
end

However, if for some strange reason you would not want to use RSpec or any test framework yourself then you can use Ruby's Kernel#at_exit method:

# somewhere
$browser = Watir::Browser.new
at_exit { $browser.close if $browser }

# other code, whenever needed
$browser.foo

I'd still recommend to use a testing framework and not create your own from scratch.

RSpec and Cucumber both have "after all" hooks.

RSpec:

describe "something" do
  before(:all) do
    @browser = Watir::Browser.new
  end
  after(:all) do
    @browser.close
  end
end

Cucumber in (env.rb):

browser = Watir::Browser.new

#teh codez

at_exit do
  browser.close
end
