Application Security Testing Gets Tasty With Sauce Labs And NT OBJECTives

December 15th, 2014 by Amber Kaplan

Finally, a win-win-win for development, QA, and security! If your development team is looking for easier ways to incorporate security earlier in a way that’s simple, easy and that your team to understand, we may have a solution for you. Security defects are like any other defect. Finding them early saves money and time. There are tools that execute security tests for security professionals – like NT OBJECTives’ NTOSpider. NTOSpider can use the application knowledge defined Selenium scripts to execute a better, more comprehensive security test on an application. (more…)

Appium Bootcamp – Chapter 6: Run Your Tests

August 7th, 2014 by Amber Kaplan

appium_logoThis is the sixth post in a series called Appium Bootcamp by noted Selenium expert Dave HaeffnerRead:  Chapter 1 Chapter 2 | Chapter 3 | Chapter 4 | Chapter 5 | Chapter 6 | Chapter 7 | Chapter 8

Dave recently immersed himself in the open source Appium project and collaborated with leading Appium contributor Matthew Edwards to bring us this material. Appium Bootcamp is for those who are brand new to mobile test automation with Appium. No familiarity with Selenium is required, although it may be useful. This is the sixth of eight posts; two new posts will be released each week.

Now that we have our tests written, refactored, and running locally it’s time to make them simple to launch by wrapping them with a command-line executor. After that, we’ll be able to easily add in the ability to run them in the cloud.

Quick Setup

appium_lib comes pre-wired with the ability to run our tests in Sauce Labs, but we’re still going to need two additional libraries to accomplish everything; rake for command-line execution, and sauce_whisk for some additional tasks not covered by appium_lib.

Let’s add these to our Gemfile and run bundle install.

# filename: Gemfile

source 'https://rubygems.org'

gem 'rspec', '~> 3.0.0'
gem 'appium_lib', '~> 4.0.0'
gem 'appium_console', '~> 1.0.1'
gem 'rake', '~> 10.3.2'
gem 'sauce_whisk', '~> 0.0.13'

Simple Rake Tasks

Now that we have our requisite libraries let’s create a new file in the project root called Rakefile and add tasks to launch our tests.

# filename: Rakefile

desc 'Run iOS tests'
task :ios do
  Dir.chdir 'ios'
  exec 'rspec'
end

desc 'Run Android tests'
task :android do
  Dir.chdir 'android'
  exec 'rspec'
end

Notice that the syntax in this file reads a lot like Ruby — that’s because it is (along with some Rake specific syntax). For a primer on Rake, read this.

In this file we’ve created two tasks. One to run our iOS tests, and another for the Android tests. Each task changes directories into the correct device folder (e.g., Dir.chdir) and then launches the tests (e.g., exec 'rspec').

If we save this file and run rake -T from the command-line, we will see these tasks listed along with their descriptions.

> rake -T
rake android  # Run Android tests
rake ios      # Run iOS tests

If we run either of these tasks (e.g., rake android or rake ios), they will execute the tests locally for each of the devices.

Running Your Tests In Sauce

As I mentioned before, appium_lib comes with the ability to run Appium tests in Sauce Labs. We just need to specify a Sauce account username and access key. To obtain an access key, you first need to have an account (if you don’t have one you can create a free trial one here). After that, log into the account and go to the bottom left of your dashboard; your access key will be listed there.

We’ll also need to make our apps available to Sauce. This can be accomplished by either uploading the app to Sauce, or, making the app available from a publicly available URL. The prior approach is easy enough to accomplish with the help of sauce_whisk.

Let’s go ahead and update our spec_helper.rb to add in this new upload capability (along with a couple of other bits).

# filename: common/spec_helper.rb

require 'rspec'
require 'appium_lib'
require 'sauce_whisk'

def using_sauce
  user = ENV['SAUCE_USERNAME']
  key  = ENV['SAUCE_ACCESS_KEY']
  user && !user.empty? && key && !key.empty?
end

def upload_app
  storage = SauceWhisk::Storage.new
  app = @caps[:caps][:app]
  storage.upload app

  @caps[:caps][:app] = "sauce-storage:#{File.basename(app)}"
end

def setup_driver
  return if $driver
  @caps = Appium.load_appium_txt file: File.join(Dir.pwd, 'appium.txt')
  if using_sauce
    upload_app
    @caps[:caps].delete :avd # re: https://github.com/appium/ruby_lib/issues/241
  end
  Appium::Driver.new @caps
end

def promote_methods
  Appium.promote_singleton_appium_methods Pages
  Appium.promote_appium_methods RSpec::Core::ExampleGroup
end

setup_driver
promote_methods

RSpec.configure do |config|

  config.before(:each) do
    $driver.start_driver
  end

  config.after(:each) do
    driver_quit
  end

end

Near the top of the file we pull in sauce_whisk. We then add in a couple of helper methods (using_sauce and upload_app). using_sauce checks to see if Sauce credentials have been set properly. upload_app uploads the application from local disk and then updates the capabilities to reference the path to the app on Sauce’s storage.

We put these to use in setup_driver by wrapping them in a conditional to see if we are using Sauce. If so, we upload the app. We’re also removing the avd capability since it will cause issues with our Sauce run if we keep it in.

Next we’ll need to update our appium.txt files so they’ll play nice with Sauce.

 

# filename: android/appium.txt

[caps]
appium-version = "1.2.0"
deviceName = "Android"
platformName = "Android"
platformVersion = "4.3"
app = "../../../apps/api.apk"
avd = "training"

[appium_lib]
require = ["./spec/requires.rb"]
# filename: ios/appium.txt

[caps]
appium-version = "1.2.0"
deviceName = "iPhone Simulator"
platformName = "ios"
platformVersion = "7.1"
app = "../../../apps/UICatalog.app.zip"

[appium_lib]
require = ["./spec/requires.rb"]

In order to work with Sauce we need to specify the appium-version and the platformVersion. Everything else stays the same. You can see a full list of Sauce’s supported platforms and configuration options here.

Now let’s update our Rake tasks to be cloud aware. That way we can specify at run time whether to run things locally or in Sauce.

desc 'Run iOS tests'
task :ios, :location do |t, args|
  location_helper args[:location]
  Dir.chdir 'ios'
  exec 'rspec'
end

desc 'Run Android tests'
task :android, :location do |t, args|
  location_helper args[:location]
  Dir.chdir 'android'
  exec 'rspec'
end

def location_helper(location)
  if location != 'sauce'
    ENV['SAUCE_USERNAME'], ENV['SAUCE_ACCESS_KEY'] = nil, nil
  end
end

We’ve updated our Rake tasks so they can take an argument for the location. We then use this argument value and pass it to location_helper. The location_helper looks at the location value — if it is not set to 'sauce'then the Sauce credentials get set to nil. This helps us ensure that we really do want to run our tests on Sauce (e.g., we have to specify both the Sauce credentials AND the location).

Now we can launch our tests locally just like before (e.g., rake ios) or in Sauce by specifying it as a location (e.g., rake ios['sauce'])

But in order for the tests to fire in Sauce Labs, we need to specify our credentials somehow. We’ve opted to keep them out of our Rakefile (and our test code) so that we can maintain future flexibility by not having them hard-coded; which is also more secure since we won’t be committing them to our repository.

Specifying Sauce Credentials

There are a few ways we can go about specifying our credentials.

Specify them at run-time

SAUCE_USERNAME=your-username SAUCE_ACCESS_KEY=your-access-key rake ios['sauce']

Export the values into the current command-line session

export SAUCE_USERNAME=your-username
export SAUCE_ACCESS_KEY=your-access-key

Set the values in your bash profile (recommended)

# filename: ~/*.bash_profile

...
export SAUCE_USERNAME=your-username
export SAUCE_ACCESS_KEY=your-access-key

After choosing a method for specifying your credentials, run your tests with one of the Rake task and specify 'sauce' for the location. Then log into your Sauce Account to see the test results and a video of the execution.

Making Your Sauce Runs Descriptive

It’s great that our tests are now running in Sauce. But it’s tough to sift through the test results since the name and test status are nondescript and all the same. Let’s fix that.

Fortunately, we can dynamically set the Sauce Labs job name and test status in our test code. We just need to provide this information before and after our test runs. To do that we’ll need to update the RSpec configuration incommon/spec_helper.rb.

 

# filename: common/spec_helper.rb

...
RSpec.configure do |config|

  config.before(:each) do |example|
    $driver.caps[:name] = example.metadata[:full_description] if using_sauce
    $driver.start_driver
  end

  config.after(:each) do |example|
    if using_sauce
      SauceWhisk::Jobs.change_status $driver.driver.session_id, example.exception.nil?
    end
    driver_quit
  end

end

In before(:each) we update the name attribute of our capabilities (e.g., caps[:name]) with the name of the test. We get this name by tapping into the test’s metadata (e.g., example.metadata[:full_description]). And since we only want this to run if we’re using Sauce we wrap it in a conditional.

In after(:each) we leverage sauce_whisk to set the job status based on the test result, which we get by checking to see if any exceptions were raised. Again, we only want this to run if we’re using Sauce, so we wrap it in a conditional too.

Now if we run our tests in Sauce we will see them execute with the correct name and job status.

Outro

Now that we have local and cloud execution covered, it’s time to automate our test runs by plugging them into a Continuous Integration (CI) server.

How HotelTonight.com Leverages Appium for Mobile Test Automation

July 1st, 2014 by Amber Kaplan

We love this blog post written by Quentin Thomas at HotelTonight! In it, he explains how they use Appium to automate their mobile tests. He also walks readers through specifics, such as the RSpec config helper. Read a snippet below.

Thanks to the engineers at Sauce Labs, it is now possible to tackle the mobile automation world with precision and consistency.

Appium, one of the newest automation frameworks introduced to the open source community, has become a valuable test tool for us at HotelTonight. The reason we chose this tool boils down to Appium’s philosophy.

“Appium is built on the idea that testing native apps shouldn’t require including an SDK or recompiling your app. And that you should be able to use your preferred test practices, frameworks, and tools”.

-Quentin Thomas, HotelTonight, June 17, 2014

Bleacher Report’s Continuous Integration & Delivery Methodology: Test Analytics

June 24th, 2014 by Amber Kaplan

This is the final post in a three part series highlighting Bleacher Report’s continuous integration and delivery methodology by Felix Rodriguez.  Read the first post here and the second here.

Last week we discussed setting up an integration testing server that allows us to post, which then kicks off a suite of tests. Now that we are storing all of our suite runs and individual tests in a postgres database, we can do some interesting things – like track trends over time. At Bleacher Report we like to use a tool named Librato to store our metrics, create sweet graphs, and display pretty dashboards. One of the metrics that we record on every test run is our PageSpeed Insights score.

PageSpeed Insights

PageSpeed insights is a tool provided by Google developers that analyzes your web or mobile page and gives you an overall rating. You can use the website to get a score manually, but instead we hooked into their api in order to submit our page visit score to Liberato. Each staging environment is recorded separately so that if any of them return measurements that are off, we can attribute this to a server issue.

average page speeds

Any server that shows an extremely high rating is probably only loading a 500 error page. A server that shows an extremely low rating is probably some new, untested JS/CSS code we are running on that server.

Below is an example of how we submit a metric using Cukebot:

generic_steps.rb

require_relative 'lib/pagespeed'
Given(/^I navigate to "(.*?)"$/) do |path|
  visit path
  pagespeed = PageSpeed.new(current_url)
  ps = pagespeed.get_results
  score = ps["score"]
  puts "Page Speed Score is: #{score}"
  metric = host.gsub(/http\:\/\//i,"").gsub(/\.com\//,"") + "_speed"
  begin
    pagespeed.submit(metric,score)
  rescue
    puts "Could not send metric"
  end
end

lib/pagespeed.rb

require 'net/https'
require 'json'
require 'uri'
require 'librato/metrics'

class PageSpeed
  def initialize(domain,strategy='desktop',key=ENV['PAGESPEED_API_TOKEN'])
    @domain = domain
    @strategy = strategy
    @key = key
    @url = "https://www.googleapis.com/pagespeedonline/v1/runPagespeed?url=" + \
      URI.encode(@domain) + \
      "&key=#{@key}&strategy=#{@strategy}"
  end

  def get_results
    uri = URI.parse(@url)
    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    request = Net::HTTP::Get.new(uri.request_uri)
    response = http.request(request)
    JSON.parse(response.body)
  end

  def submit(name, value)
    Librato::Metrics.authenticate "ops@bleacherreport.com", ENV['LIBRATO_TOKEN']
    Librato::Metrics.submit name.to_sym  => {:type => :gauge, :value => value, :source => 'cukebot'}
  end
end

 

Google’s PageSpeed Insights return relatively fast, but as you start recording more metrics on each visit command to get results on both desktop and mobile, we suggest building a separate service that will run a desired performance test as a post – or at least in its own thread. This will stop the test from continuing its run or causing a test that runs long. Which brings us to our next topic.

Tracking Run Time

With Sauce Labs, you are able to quickly spot a test that takes a long time to run. But when you’re running hundreds of tests in parallel, all the time, it’s hard to keep track of the ones that normally take a long time to run versus the ones that have only recently started to take an abnormally long time to run. This is why our Cukebot service is so important to us.

Now that each test run is stored in our database, we grab the information Sauce stores for run time length and store it with the rest of the details from that test. We then submit that metric to Librato and track over time in an instrument. Once again, if all of our tests take substantially longer to run on a specific environment, we can use that data to investigate issues with that server.

To do this, we take advantage of Cucumber’s before/after hooks to grab the time it took for the test to run in Sauce (or track it ourselves) and submit to Librato. We use the on_exit hook to record the total time of the suite and submit that as well.

Test Pass/Fail Analytics

To see trends over time, we’d also like to measure our pass/fail percentage for each individual test on each separate staging environment as well as our entire suite pass/fail percentage. This would allow us to notify Ops about any servers that need to get “beefed up” if we run into a lot of timeout issues on that particular setup. This would also allow us to quickly make a decision about whether we should proceed with a deploy or not when there are failed tests that pass over 90% of the time and are currently failing.

The easiest way to achieve this is to use the Cucumber after-hook to query the postgres database for total passed test runs on the current environment in the last X amount of days, and divide that by the total test runs on the current environment in the same period to generate a percentage, store it, then track it over time to analyze trends.

Summary:

Adding tools like these will allow you to look at a dashboard after each build and give your team the confidence to know that your code is ready to be released to the wild.

Running integration tests continuously used to be our biggest challenge.  Now that we’ve finally arrived to the party, we’ve noticed that there are many other things we can automate. As our company strives for better product quality, this pushes our team’s standards with regard to what we choose to ship.

One tool we have been experimenting with and would like to add to our arsenal of automation is Blitz.io. So far we have seen great things from them and have caught a lot of traffic-related issues we would have missed otherwise.

Most of what I’ve talked about in this series has been done, but some is right around the corner from completion. If you believe we can enhance this process in anyway, I would greatly appreciate any constructive criticism via my twitter handle @feelobot. As Sauce says, “Automate all the Things!”

Guest Post: Bridging the Test Divide – Beyond Testing For A Release

June 16th, 2014 by Amber Kaplan

This is the second of a three part series by Matthew Heusser, software delivery consultant and writer. 

When I start to think about testing, I think about it in two broad strokes: new feature testing and release-testing. New feature testing tries to find problems with something new and specific, while release-testing happens after “code complete”, to make sure the whole system works together, that a change here didn’t break something there.

Release-testing (which some call regression testing) slows down the pace of release and delays feedback from our customer. Release-testing also increases cycle time – the time from when we begin work on a feature until it hits production. Over time, as our software become more complex, the amount of testing we want to do during release testing goes up.

Meanwhile, teams want to ship more often, to tighten the feedback loop.

Today I am going to talk about making release testing go away – or at least drastically reducing it.

It all starts during that tutorial in Spain I wrote about last time.

Two Worlds

The frequency of release for the people in my tutorial was very diverse, but two groups really struck me — the telecom that had a four-month test-release cycle, and the Latvian software team with the capability to deploy to production every single day.

That means arriving at the office the morning, looking at automated test runs, and making a decision to deploy.

There is a ‘formula’ to make this possible. It sounds simple and easy:

  • Automate a large number of checks on every build
  • Automate deploy to production
  • Continuously monitor traffic and logs for errors
  • Build the capability to rollback on failure

That transforms the role of test from doing the “testing we always do” to looking at the risk for a given release, lining it up against several different test strategies, and balancing risk, opportunity, reward, and time invested in release-testing?

The trick is to stop looking at the software as a big box, but instead to see it as a set of components. The classic set of components are large pieces of infrastructure (the configuration of the web server, the connections to the database, search, login, payment) and the things that sit on top of that – product reviews, comments, static html pages, and so on. Develop at least two de-ploy strategies — one for audited and mission-critical systems (essential infrastructure, etc) and another for components and add-ons.

We’ve been doing it for years in large IT organizations, where different systems have different release cycles; the trick is to split up existing systems, so you can recognize and make low-risk changes easier.

This isn’t something I dreamed up; both Zappos and Etsy have to pass PCI audits for financial services, while Zappos is part of Amazon and publicly traded. Both of these organizations have a sophisticated test-deploy process for parts of the application that touch money, and a simpler process for lower-risk changes.

So split off the system into different components that can be tested in isolation. Review the changes (perhaps down to the code level) to consider the impact of the change, and test the appropriate amount.

This can free up developers to make many tiny changes per day as long as those changes are low risk. Bigger changes along a theme can be batched together to save testing time — and might mean we can deploy with still considerably less testing than a ‘full’ site retest.

But How Do We Test It?

A few years ago, the ideal vision of getting away from manual, documented test cases was a single ‘test it’ button combined with a thumbs up or down at the end of an “automated test run.”

If the risk is different for each release, and we are uncomfortable with our automation, then we actually want to run different tests for each release — exactly what thinking testers (indeed, anyone on the team) can do with exploratory testing.

So let the computers provide some automated checks, all the time. Each morning, maybe every half an hour, we get a report, look at the changes, and decide what is the right thing for this re-lease. That might mean full-time exploratory testing of major features for a day or two, it might be emailing the team and asking everyone to spend a half hour testing in production.

This result is grown up software testing, varying the test approach to balance risk with cost.

The first step that I talked about today is separating components and developing a strategy that changes the test effort based on which parts were changed. If the risk is minimal, then deploy it every day. Hey, deploy it every hour.

This formula is not magic. Companies that try it find engineering challenges. The first build/deploy system they write tends to become hard to maintain over time. Done wrong continuous testing creates systematic and organizational risk.

It’s also a hard sell. So let’s talk about ways to change the system to shrink the release-test cycle, deploy more often, and reduce risk. The small improvements we make will stand on their own, not threaten anyway — and allow us to stop at any time and declare victory!

A Component Strategy

that_badWhen a company like etsy.com says that new programmers commit and push code to production the first day, do they really mean modifications to payment processing, search, or display for all products?

Of course not.

Instead, programmers follow a well-written set of directions to … wait for it … add the new user to the static HTML ‘about us’ page that lists all the employees, along with an image. If this change generates a bug, that will probably result in an X over an image the new hire forgot to upload, or maybe, at worst, break a div tag so the page mis-renders.

A bad commit on day one looks like this – not a bungled financial transaction in production.

How much testing should we have for that? Should we retest the whole site?

Let’s say we design the push to production so the ‘push’ only copies HTML and image files to the webserver. The server is never ‘down’, and serves complete pages. After the switch, the new page appears. Do we really need to give it the full monty, the week-long burn down of all that is good and right in testing? Couldn’t the developer try it on a local machine, push to stag-ing, try again, and “just push it?”

Questions on how?

More to come.

Re-Blog: JavaScript Multi Module Project – Continuous Integration

June 11th, 2014 by Amber Kaplan

lubos-krnacOur friend Lubos Krnac describes how to integrate Sauce with Protractor in a quest to implement continuous integration in his JavaScript multi module project with Grunt.

Below is a quote from his most recent blog post along side some code.

Read the rest of his post to get the full how-to here.

An important part of this setup is Protractor integration with Sauce Labs. Sauce Labs provides a Selenium server with WebDiver API for testing. Protractor uses Sauce Labs by default when you specify their credentials. Credentials are the only special configuration in test/protractor/protractorConf.js (bottom of the snippet). The other configuration was taken from the grunt-protractor-coverage example. I am using this Grunt plug-in for running Protractor tests and measuring code coverage.

You may ask “how can I use localhost in the configuration, when a remote selenium server is used for testing?” Good question. Sauce Labs provides a very useful feature called Sauce Connect. It is a tunnel that emulates access to your machine from a Selenium server. This is super useful when you need to bypass company firewall. It will be used later in main project CI configuration.
