Can i get an aws lambda to run an rspec test?

I got it working locally.
In aws i am getting an error.

Locally I use

run_lambda_function.rb

require_relative 'lambda_function'
lambda_handler(event: {}, context: Object.new)

Which calls

lambda_function.rb

require 'aws-sdk-lambda'
require 'json'
require 'rspec'
require 'capybara'
require 'capybara/rspec'
require 'webdrivers'

def lambda_handler(event:, context:)
  @@short_sleep = 1 # just for these viewing and debugging purposes :)
  Capybara.app_host = 'https://google.com'
  RSpec::Core::Runner.run(['spec/google_spec.rb']) #, $stderr, $stdout)
end

which uses spec:

spec/google_spec.rb

describe 'Visi Websites', type: :feature do
  it 'can visit google' do
    visit '/'
    expect(page).to have_css('div')
    sleep @@short_sleep
  end
  it 'can visit gogole/forms' do
    visit '/forms'
    expect(page).to have_css('div')
    sleep @@short_sleep
  end
end

This runs locally but when I bundle to code to vendor/ and zip it all up, upload it to lambda (via S3 bucket due to size > 50k for dependencies*) and try to run it in aws mgtmt console I get an error in webdrivers:

I might be able to avoid with serverless and other approaches perhaps but I am trying to stay as simple and low-level without dependencies and aids while I am learning. Within reason of course. No hoops.

  • dependencies

Gemfile

for locally bundling while testing, not relevant (I think) to uploaded code as I bundled that to /vendor and zipped it all (hence the large size and need for load via s3 bucket)

source 'http://rubygems.org'

gem 'rspec'
gem 'webdrivers'
gem 'capybara'
gem 'aws-sdk'
Solution

  • It seems you are trying to run GUI based testing in Lambda environment. Lambda does not have access to display devices. You should try to run your test cases in the headless mode.
