Encountering a problem where an error is being thrown when using @driver.quit in the after(:context) block

Question

Encountering a problem where an error is being thrown when using @driver.quit in the after(:context) block

Currently experimenting with this code snippet

require 'rspec'
require 'selenium-webdriver'

RSpec.describe 'Brand new test' do

  before :each do
    @driver = Selenium::WebDriver.for (:firefox)
  end

  after :all do
    @driver.quit
  end

  it 'will sign up and generate a fresh user' do
    p 'testing'
  end
end

In the course of running this, an error arose

rspec test.rb                                                                                                                     [13:04:18]
"testing"
.
An issue surfaced in an `after(:context)` hook.
Failure/Error: @driver.quit

NoMethodError:
  undefined method `quit' for nil:NilClass
# ./test.rb:11:in `block (2 levels) in <top (required)>'


Completed in 4.61 seconds (files took 0.17828 seconds to load)
1 example, 0 failures

I am certain that I am missing something minor, but my efforts have failed thus far. Any assistance would be welcomed.

Coupled with FF or selenium version mismatch?

The versions in use are FF 45, selenium 2.53, and rspec 3.5.4.

Answer №1

The issue at hand pertains to RSpec functionality. In RSpec, before/after(:all) hooks are limited in their access to instance variables. They can only reach variables defined within their scope or outer scopes, not those specified in the current test being executed. However, after(:each) hooks do have the ability to access instance variables declared in the current test.

before :all do
 @x = 5
end

context "example" do
  before :all do
    @y = 6
  end

  it "test case" do
    @z = 7
    # @x, @y, and @z accessible here
  </div>

  after :each do
   #@x, @y, @z accessible here
  </div>

  after :all do
    # @x, @y accessible here
</div>
