Overview
A Selenium Unit Test Framework for Selenium with the Selenium Python client.
Selenium is an open-source web application automation and testing framework. Tests are written using WebDriver-compatible language-specific client libraries.
The Selenium tests are written in Python and run through the language’s built-in unittest framework. A custom test runner and reporter handle boilerplate Selenium setup along with storage of results in a json file for post-processing.

Using the Chrome Developer Console
Description
Allows direct interaction and inspection of the web app in real-time via the web browser’s console. This is helpful when debugging or writing tests because it allows you to see a list of DOM elements on each page of the web app along with their properties. For example while writing a test you will need to click buttons, interact with forms, verify properties, etc. In order to write such a test, you will need to reference elements by id, name, or some other identifiers. The fastest way to figure out how to reference an element is by navigating to the page of the web app where the test will start from using the browser, right clicking on elements and selecting “Inspect Element” from the context menu, then trying to reference the element through the Chrome Developer Console using the commands below.
Useful commands
$() Returns the first element that matches the CSS selector specified within the parantheses. It is a shortcut for document.querySelector() $$() Returns an array of all the elements that match the CSS selector specified within the parantheses. This is an alias for document.querySelectorAll() $x() Returns an array of elements that match the XPath specified within the parantheses.
Element query examples
$x("//span[text()='Guidebook']") Returns an array of span tag elements containing the text “Guidebook”. $("p.usm_name span").textContent Returns the text content of the first span tag element which is a child of a “p” element with class “usm_name”.
