Agenda

• Part1– Selenium Grid and Jenkins– xUnit frameworks– Issues with some browsers

• Part2– Selenium in the cloud. Integration with various

cloud services– Build your own infrastructure in the cloud

Part 1

Using selenium for functional testing in continuous integration.

How QA always like

Well, maybe not always

Introduction. How do we QA?

• What do we always have:– QA mess on the project– How to support all specifications– Team coordination?!

• What do we want to achieve:– Results visibility– Better cooperation– Customer satisfaction

Customer satisfaction

Selenium Grid and Jenkins plugin.

• What is Continuous Integration• Role of Selenium Grid in CI• Jenkins Selenium plugin• Other plugins that should help:– Test Report (xUnit)– Violations, TestCoverage– Rebuild– Extended choice plugin– Repository connectors

Custom Job

Using Jenkins

How can Jenkins serve you

• What it helps and what it doesn’t• Create as many jobs as needed• CI for you project is not only test automation• Has a lot of really useful plugins and features• Let your all team work on it, not only you

Selenium Grid

Jenkins Selenium Plugin

Pros

• Almost as built-in. Easy to install and track

• Console output• All in one

Cons

• Manual update to new Selenium Server through workaround

• No control

New Selenium Grid

Nodes tune-up

• How to add multiple OS/ browser version support

• Different run-scripts for every browser– Firefox profile template– Googlechrome driver– Iexplore security issues

• Autostart tasks• VM environment

Tune-up

Browser support

Potential Browser problems

• It all suck, no ONE FITS ALL solution– Better to do it one by one– Start with easier

• Windows is Windows– Different CSS and XPATH – Slow performance

• SSL support• Proxy support• Let you control the browser not browser control you

Universal Framework

Nosetests as a universal xUnit framework

• Features– Unitest plugin support– Short commands– Junit result output

• Plugins– Include third-party plugins– Testconfig

Result of in-house testing

Part 2

Selenium in the cloud. Integration with BrowserMob, SauceLabs,

ShiningPanda, AmazonEC2

How could cloud testing help your project. When to turn cloud.

• When you need cloud services:– Everybody needs unless you’re not Facebook,

Google, Cisco– Having own cluster base is expensive– You have a start-up and your team is remote– You want to quickly show results to customers,

investors etc.

Cloud Providers

Semi-paid and semi-free services.

• A lot of services grow up recently:– Saas services– Cloud hosting(Amazon, Rackspace)

• You are the boss, you choose:– Strong tech skills and you want full control –

Rackspace, Amazon EC2– Less skills to admin – Sauce Labs, BrowserMob,

others

Load Testing

Traditional Load Testing

Pros• Everything is configurable to

yourself• A lot of Free tools (Jmeter,

Grinder etc.)

Cons• Takes weeks to build good

working test infrastructure• A lot of computer power is

required to run really good load tests

Computing power

Load Testing with BrowserMob

Ready cloud services

Pros• Already includes all services

you only start thinking of• Video capturing and good

error parsing• Easy API

Cons

• Non-free use• Dependency on the service

provider

SauceOnDemand

Shining Panda

Is it Really Fast?

Do it yourself. Dedicated Cloud

• When you need something done right, do it yourself

• Traditional way of using cloud - PaaS• A lot of providers, most of them have good pricing:– Rackspace Cloud Servers– Amazon Web Services– Joyent– GoGrid– Skytap Networks

DIY Instrument Kit

Do it yourself. Dedicated Cloud

Pros• Everything is configurable to

yourself• You pay only for monthly

hosting• You can switch to cloud

from your local-built environment

Cons• Takes a lot of time to build

good working test infrastructure

• Harder support• Needs smart Developers in

Test to design frameworks
