1. Page Objects – encapsulates the way of identification and logical grouping of widgets.
2. Page Object == Logical Page
3. Page Object != Physical Page
Page Object – just to “refresh”

7CONFIDENTIAL
Page Object – “example” 

8CONFIDENTIAL
Page Object – “example” 

9CONFIDENTIAL
1. Let’s compare:
– Photo
• Share – looks like parallelism (easy parallelism).
– Video
• Share – looks like parallelism (not trivial parallelism).
State-less or state-full solution?

10CONFIDENTIAL
1. How easy transform solution from “single” to “multi” threading (to decrease “QA
Automation Windows”)
– State-less – like share a photo
• Just 5 minutes of work.
– State-full – like share a video
• Not trivial task, could be a night mare.
2. Summary
– prefer state-less solutions to state-full solutions in mooooost cases;
– before start implementation a state-full solution, please, take a break for a minute, and re-
thing everything again, possibly you can find a proper state-less solution.
State-less or state-full solution?

11CONFIDENTIAL
1. Static class
– could be implemented as a state-less solution easily
2. Object
– State-full solution in 99,99% cases
3. Summary
– prefer static class based solutions (state-less) to object based (state-full) in mooooost cases;
– before start implementation based on objects, please, take a break for a minute, and re-thing
everything again, possibly you can find a proper solution based on static classes.
Object or static class State-full or state-less solution?

12CONFIDENTIAL
1. Too complicated business logic due to Domain
2. Too complicated business logic due to System size (thousands test-cases)
3. Too many “contexts”
– Browser versions
– Environments
– Customers with a tiny nuances of functionality
– Platforms (cross-browser Web plus cross-platform Mobile)
– Combination 
4. Combination 
Page Objects – state-full, general case

13CONFIDENTIAL
1. Web UI that behaves like a Wizard
2. Web UI in combination with Mobile in one use case
3. Internet of Things (in most cases)
4. More then 1 page during 1 test (for example several portals or several instances of one
portal to implement one “business use case”):
– Really seldom;
– Looks like integration tests (in most cases):
• Std solution- some type of White Box Testing.
5. Many others “special cases”
Page Objects – state-full, special cases

14CONFIDENTIAL
How to select a proper PO implementation?

15CONFIDENTIAL
1. 30 Physical Pages
2. Standard Header, footer and search functionality for all physical pages
3. Each Physical Page consists of
– Header – H
– Footer – F
– Search – S
– Some functionality, specific for the Page – U (unique)
Hypothetical project context – to compare

16CONFIDENTIAL
1. 33 Static Page Objects = Logical Pages
2. 0 explicit and 30 implicit Physical Pages
3. Just share 33 Static Page Objects between 30 implicit Physical Pages
– For example, Header Static Page Object (static class) is used in test cases for all 30 Physical
Page Objects
4. Complexity – just 33 static state-less entities (plus limitations due to state-less solutions)
Compare complexity – Static Page Object based

17CONFIDENTIAL
1. 33 Dynamic Page Objects = Logical Pages
2. It depends on implementation (one of the ways):
– 0 explicit and 30 implicit Physical Pages
– implicit Physical Page implements on Action layer (limitations example)
– Action for Physical Page aggregates all necessary Dynamic Logical Pages
• Physical Pages are implemented in a next way: create all necessary instances of logical pages, aggregate in
some way, use Action layer as an point of aggregation in most cases, free resources
Compare complexity – Dynamic Page Object based (option 1)

18CONFIDENTIAL
1. 120 objects (min), each with some state, dynamically created and frees to implement
necessary behavior - to implement 30 implicit Physical Pages
2. Complexity – 120 dynamic, state-full entities min (plus some limitations due to state-full
solution implementation nuances)

19CONFIDENTIAL
1. 33 Dynamic Page Objects = Logical Pages
2. It depends on implementation (another way):
– 30 explicit Physical Pages
– Multiple Interface inheritance
– Combine Page Objects and Actions layer (in most cases)
– Action-Physical Page (limitations example)
• Implements all Logical Pages interfaces using aggregation and “delegation”
• Aggregate all Dynamic Logical Page Objects
• Create and frees resources (Dynamic Logical Page Objects)

20CONFIDENTIAL
1. 150 objects, each with some state, dynamically created and frees to implement necessary
behavior - to implement 30 explicit Physical Pages
2. Complexity – 150 dynamic, state-full not trivial entities with a multiple interface
inheritance (plus some limitations due to state-full solution implementation nuances)

21CONFIDENTIAL
1. Can be used together with next Design Patterns Approaches
– Action (both static – preferable and dynamic)
– Key-word driven
– DSL – external only
– BDD – partially, it depends on exact BDD engine implementation limitations
2. Can’t be used together with next Design Patterns
– Factory
– Flow (Fluent Interface)
– Navigator (for Web)
Compare “tech” limitations - Static Page Object based

22CONFIDENTIAL
1. No limitations, but …
– For example, in most cases it’s hard to isolate Action and Page Objects layers
Compare “tech” limitations - Dynamic Page Object based

23CONFIDENTIAL
1. Too complicated business logic due to Domain
2. Too complicated business logic due to System size (thousands test-cases)
3. Too many “contexts”

– Combination 
4. Combination 
Compare “business” limitations - Static

24CONFIDENTIAL
1. State-less approach - you have a conditional that chooses different behavior depending on
…
2. Solution to simplify the project – refactoring “Replace Conditional with Polymorphism”
3. Polymorphism = object = State-full approach
Rationale “business” limitations - Static

25CONFIDENTIAL
1. “From refactoring to Patterns”
– There is a set of specific Design Patterns
2. The trickiest part – find a balance for your project now and update point of balance in time
Rationale “business” limitations - Static

26CONFIDENTIAL
1. Relatively simple business logic due to Domain
2. Relatively simple business logic due to System size (hundreds test-cases)
3. Not so many “contexts”

Compare “business” limitations - Dynamic

27CONFIDENTIAL
1. State-full approach - you have a set of objects classes, which developed, possibly, using
several Design Patterns to implement necessary functionality – to choose different behavior
depending on …
2. Solution to simplify the project – refactoring “Replace Polymorphism with Conditional”
3. Polymorphism ~= object ~= State-full approach
4. No Polymorphism ~= no objects ~= State-less approach
Rationale “business” limitations - Dynamic

28CONFIDENTIAL
1. “From Patterns to refactoring”
– There is no need to use a set of specific Design Patterns

30CONFIDENTIAL
Page Factory from Selenium library

31CONFIDENTIAL
Page Factory - definition
1. Page Factory is an inbuilt page object model concept for Selenium WebDriver but it is very
optimized.
2. We use initElements method to initialize web elements
3. Additionally with the help of PageFactory class - use annotations @FindBy to find WebElement.
4. @FindBy can accept as attributes:
1. tagName
2. name
3. partialLinkText
4. linkText
5. Id
6. Css
7. className
8. Xpath

32CONFIDENTIAL
Page Factory - notes
1. If you use the PageFactory, you can assume that the fields are initialized. If you don't use the
PageFactory, then NullPointerExceptions will be thrown if you make the assumption that the fields
are already initialized.
2. List<WebElement> fields are decorated if and only if they have @FindBy or @FindBys annotation.
Default search strategy "by id or name" that works for WebElement fields is hardly suitable for
lists because it is rare to have several elements with the same id or name on a page.

33CONFIDENTIAL
Page Factory - notes
1. WebElements are evaluated lazily. That is, if you never use a WebElement field in a PageObject,
there will never be a call to "findElement" for it.
2. The functionality works using dynamic proxies. This means that you shouldn't expect a
WebElement to be a particular subclass, even if you know the type of the driver. For example, if
you are using the HtmlUnitDriver, you shouldn't expect the WebElement field to be initialized with
an instance of HtmlUnitWebElement.

Serenity (ex. Thucydides)
1. Serenity (Thucydides) – is an open-source tool, oriented on effective acceptance testing and
detailed documentation and reports of the project.
2. It works with Junit and BDD tools like JBehave and Cucumber-JVM, and gives a wide API for
automated testing with integrity with Selenium Webdriver.
3. It is made for the following tasks:
• Creating more flexible tests, which are easier to be supported
• Getting illustrated story-based reports
• Clear context of connection between tests and requirements
• Measurement of requirements coverage.

93CONFIDENTIAL
Serenity (ex. Thucydides) workflow
• Step 1: Defining requirement and acceptance criteria
It starts from requirements, which are need to be tested. For every requirement there is an
acceptance criteria which describing the requirement better. Thucydides automate acceptance
criteria
• Step 2: Modelling the requirements
With the help of Thucydides you create a simple model of requirements made on Java language. There
are some ways of modelling requirements, including simple Java class, using convention and structure
of directories of integrating with other tools like Jira. That approach allows the developer what
requirement is tested each of the test, and give Thucydides the ability to track testing features and
requirements

94CONFIDENTIAL
• Step 3: Automation of acceptance testing
Next is describing acceptance criteria by business language is following, and automation engineers
implement them using BDD such as jBehave or Cucumber-JVM, or using Java and Junit, in order for
Thucydides to run it with “pending” status (body is not implemented)
• Step 4: Test implementation
Automation Engineers now can implement acceptance criteria in a form of real-time AUT test. Tests
can be divided into steps for better readability and easiness of support. Webdriver is used for testing.

95CONFIDENTIAL
• Step 5: Test results report
Thucydides allow you to create detailed test reports about test runs, including:
History for ach test
Screenshot for each test step
Result of test run including time and error messages
• Step 6: Requirements coverage report
Besides test run reports, Thucideds also provide information about:
Number of tested requirements
Number of passed requirements
Number of requirements which need to be run

96CONFIDENTIAL
• Step 7: Project progress report
Thucydides provide information about project history progress:
Change in number of features implemented in time
Change in quantity of implemented and tested features in time
Change of failed tests in time
• Summary
As we can see, Thucydides is a rather complex tool, build around BDD concept and acceptance testing,
using Webdriver for testing web applications.

Page Object
And what about Page Object supports …?

98CONFIDENTIAL
Page Object “default” implementation
Framework implements Page Object pattern and let’s you decrease code duplication another one type
of classes between tests and pages, called “steps”. Let’s look at “steps” with page object class:
1. public class StepsinBook extends ScenarioSteps {
2. public StepsinBook(Pages pages) {
3. super(pages);
4. }
5. public BookPage getPageBook()
6. {
7. return getPages().currentPageAt(BookPage.class);

Geb – general info
1. Tool for browser automation, made on Groovy (JVM-based) and based on Selenium Webdriver.
2. It using:
1. Selenium for browser automation
2. jQuery selectors for locating elements
3. Page object pattern
.
3. In the bounds of testing it can be easily integrated with different test frameworks like:
1. Junit
2. TestNG
3. Spock

104CONFIDENTIAL
Geb – general info
If to compare with Webdriver API, Geb provides more comfortable interface in the following areas:
• Working with Webdriver instance (creating, configuration, moves, destruction)
• Locating elements (jQuery locators)
• Page object pattern
• Waiters
• Page interactions
• Work with AJAX elements
• Integration with build-tools (maven, gradle, grails)
• Integration with cloud services (Sauce labs, Browser Stack)

SWD Page Recorder
1. SWD Page Recorder helps you to create locators of web-page, debug them in the application and
generate PageObject code for classes on C#, Java, Python, Ruby, Perl for using them in Selenium
Webdriver tests.
2. That tool not only lets you find locator needed, but also optimize it and generate all the code
needed for further element declaration in the code.
3. SWD Page Recorder is a unified tool for working with locators in every browser which are
supported by Selenium.
4. Important moment that Page Recorder tests the selectors using Webdriver – so you’re not going to
have cases when locator find other way will not work in Webdriver.

Tech “basement”
• Grady Butch «Object oriented analysis and design with examples of apps on C++
Notes: IMHO No need to be afraid of C++, 95% of the material is conceptual, there is no strict
connection to chosen language. From my point of view is one of the best books for true getting to
know with OOP.
• Martin Fowler «Refactoring»
Notes: IMHO strongly recommend to read from cover to cover, twice, in order to have contents of
the book – you active professional luggage.

luggage. And then look through different chapters before talking to a customer.
• Steve McConnel “Code complete”
