Selenium Pagemodel implementation for Python.

Project description


This project helps **Test Engineers** by abstracting out the implementation -- in this case Selenium -- from the actual set of **Actions** necessary to perform a single **Test Scenario**. The Selenium-PageModel_ library does this by defining a set of well defined *PageModel* constructs that **Test Engineers** can extend/implement to describe a Website. These *PageModel* constructs includes the following:

1. WebPage
2. Button
3. Checkbox
4. Dropdown
5. Link
6. Table
7. TextElement
8. TextField
9. Widget

Using these constructs, you can describe a *WebPage* as having the following web-elements:

1. A Header *Widget* containing:
* A Home *Link*
* A Login *Link*
* A Register *Link*
2. A form *Widget* containing:
* A username *TextField*
* A password *TextField*
* A Submit *Button*
* A potential Error message *TextElement* (in the event of a login failure)

Once a *PageModel* is defined, a *login test* for an imaginary website may look like this::;

Please see the project's Homepage for more information: Selenium-PageModel_


The library can be installed via::

pip install seleniumpm

Or if you want to install from src::

pip install git+


Here is the ever so popular Google example using *seleniumpm*::

from selenium import webdriver
from seleniumpm.examples.google_page import GooglePage

Setup for Remote execution against a local standalone-selenium-server
and using the PhantomJS driver. This can be changed of course to using
the driver of your choice (e.g. Chrome or Firefox)
driver = webdriver.Remote(command_executor="http://localhost:4444/wd/hub", desired_capabilities=webdriver.DesiredCapabilities.PHANTOMJS)

# Instantiate Google Page
google = GooglePage(driver, url="")

# Open + wait for page load + validate Google

# Print the page title
print google.get_title()

# Search for 'Cheese!'
search_str = "Cheese!"

# Ensure that the page is refreshed from your search
print google.wait_for_title(search_str).get_title()

Creating your PageObject's

The GooglePage used in the above example looks like the following::

from import By
from seleniumpm.webpage import Webpage
from seleniumpm.webelements.textfield import TextField
from seleniumpm.locator import Locator

class GooglePage(Webpage):
def __init__(self, driver, url=None):
super(GooglePage, self).__init__(driver, url)
self.search_field = TextField(driver, Locator.by_name('q'))

def get_result_links(self):
links = []
elements = self.driver.find_elements(By.XPATH, "//h3[contains(@class, 'r')]/a")
for element in elements:
return links

You should notice that most of the operations except for get_result_links() are not visible on the GooglePage class. That is because the basic behaviors are either part of the Webpage or the TextField (aka an Element) type.

Language Support

The Selenium PageModel implementation is not limited to just one language. Here are other language implementations:

* **Java** - Java-SeleniumPM_
* **Ruby** - In consideration depending on needs and popularity.

Contributing to SeleniumPM

* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
* Fork the project.
* Start a feature/bugfix branch.
* Commit and push until you are happy with your contribution.
* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
* Please try not to mess with the version or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so that I can cherry-pick around it.

Release History


**New Features:**

- Moving upload of wheel to use to twine instead of See the following link for why:

2.7.0 (2017-03-20)

**New Features:**
- Adding a new ability to mark an Element type as 'invisible' so that validations on a Widget or Webpage can be done simply on presence
- Adding a new ability to mark an Element type as 'do not check' so that you could potentially define an Element that you simply don't validate using the default validation() operation defined on a Widget or a Webpage. This feature should be used sparingly as there are better design patterns to handle **most** cases that you may think that you need to avoid validating the presence of specific Element types.


2.6.0 (2017-03-17)

**New Features:**
- Adding get_tuple() to Locator object. This is to make passing between SeleniumPM and the Selenium libraries eaiser
- Adding simpler way of defining Locators. Locators can now be created via Locator.by_xpath(path) or Locator.by_css_selector(path). The following types are supported:
* by_xpath(path)
* by_css_selector(path)
* by_name(path)
* by_class_name(path)
* by_id(path)
* by_link_text(path)
* by_partial_link_text(path)
* by_tag_name(path)
- Adding wait_for_selected() to Element
- Adding wait_for_clickable() and click_invisible() to Clickable
- Adding send_keys_delayed() and type_delayed() to TextField
- Adding new Panel type that simply extends Widget. Conceptually they're exactly the same, but Panel appears to be a more generally acceptable term for a section of a page

- Simplifying README for more of a project overview. Details should be located on the wiki

2.5.2 (2017-03-07)

**New Features:**


- Fixing issue with throwing error missing HISTORY.rst from package data

2.5.1 (2017-03-07) - BROKEN

**New Features:**


- Fixing issue with set_focus() or scroll_into_view(). They were apparently not included in 2.5.0 release

2.5.0 (2017-03-07) - BROKEN

**New Features:**

- Addition of RadioButton type
- Addition of Dropdown type
- Addition of Image type
- Add new method get_element_attr() to Webpage and Widget type. This will give developers access to all define
Element attributes on a Webpage or within a Widget. This method all supports retrieving a specific Element type
(e.g. Button, Link, Checkbox)
- Changing default wait_for_page_load() and validate() methods to use the above mentioned get_element_attr(). This can
still be overridden, and does not affect previous implementations.
- Adding new seleniumpm.examples.widgets package
- Element class now implements a get_action_chains() method to return back an ActionChains type.
- Element class now implements a set_focus() or scroll_into_view() functionality, for those pesky webelements that are
need to be visible, but are corrently scrolled off page somehow.


- Adding type-checking to constructor of the Element, Widget, and Webpage types. These classes will now throw an
AttributeError if not passed in a legitimate RemoteWebdriver, URL, or Locator type as parameters.

2.4.2 (2017-02-13)

**New Features:**


- Fixing issue appending two .rst files together to generate the long_description
- Using setuptools for

2.4.1 (2017-02-13)

**New Features:**


- Using disutils.core instead of setuptools for Hoping this fixes pretty-print of rst files on PyPi

2.4.0 (2017-02-13)

**New Features:**

- Better support for Table type and interacting with them on a page. This includes support for 'search' operations and
enumerating over rows and columns
- Additional methods to Locator object to assist in managing them
- implemented get_webelement() and get_webelements() for all Elements. This will return the Selenium WebElement
- Implementation of object equality for all Selenium Page Model classes
- UnitTests are now using PhantomJS (Headless) target
- Removal of requestest dependency to keep the project simple


- The Widget type was missing in 2.3.0 release
- Expanding of the UnitTest coverage to ensure libraries are working correctly
- Fixing issue with get_text() in Python Selenium. Apparently, this call in Python (versus Java) is simply called 'text'
- Conversion of README and HISTORY files to rst. This is so that they are rendered correctly on PyPi server

2.3.0 (2017-02-06)

**New Features:**

- Provides a full implementation of the current Java v2.3 of Selenium PageModel

2.0.0 (2017-01-10)

**New Features:**

- First release of seleniumpm for the world
- Contains minimum proof-of-concept for testing search on Google
