Open Command

Syntex:

open ( url )

Arguments:
url - the URL to open; may be relative or absolute

Description:

Opens an URL in the test frame. This accepts both relative and absolute URLs. The "open" command waits for the page to load before proceeding, ie. the "AndWait" suffix is implicit. Note: The URL must be on the same domain as the runner HTML due to security restrictions in the browser (Same Origin Policy). If you need to open an URL on another domain, use the Selenium Server to start a new browser session on that domain.

Implementation:

selenium.open("http://www.google.com");

What is Selenium RC (Remote Control) ?

Selenium Remote Control (RC) is a test tool that allows you to write automated web application UI tests in any programming language against any HTTP website using any mainstream JavaScript-enabled browser.
Selenium RC comes in two parts.

A server which automatically launches and kills browsers, and acts as a HTTP proxy for web requests from them.
Client libraries for your favorite computer language.

Here is a simplified architectural representation....

Selenium Remote Control is great for testing complex AJAX-based web user interfaces under a Continuous Integration system. It is also an ideal solution for users of Selenium IDE who want to write tests in a more expressive programming language than the Selenese HTML table format.

What is a Selenium Command?

A command is what tells Selenium what to do. Selenium commands come in three 'flavors': Actions, Accessors and Assertions. Each command call is one line in the test table of the form:

command target value

Actions are commands that generally manipulate the state of the application. They do things like "click this link" and "select that option". If an Action fails, or has an error, the execution of the current test is stopped.
Many Actions can be called with the "AndWait" suffix, e.g. "clickAndWait". This suffix tells Selenium that the action will cause the browser to make a call to the server, and that Selenium should wait for a new page to load.
Accessors examine the state of the application and store the results in variables, e.g. "storeTitle". They are also used to automatically generate Assertions.
Assertions are like Accessors, but they verify that the state of the application conforms to what is expected. Examples include "make sure the page title is X" and "verify that this checkbox is checked".
All Selenium Assertions can be used in 3 modes: "assert", "verify", and "waitFor". For example, you can "assertText", "verifyText" and "waitForText". When an "assert" fails, the test is aborted. When a "verify" fails, the test will continue execution, logging the failure. This allows a single "assert" to ensure that the application is on the correct page, followed by a bunch of "verify" assertions to test form field values, labels, etc.
"waitFor" commands wait for some condition to become true (which can be useful for testing Ajax applications). They will succeed immediately if the condition is already true. However, they will fail and halt the test if the condition does not become true within the current timeout setting.
Element Locators tell Selenium which HTML element a command refers to. Many commands require an Element Locator as the "target" attribute. Examples of Element Locators include "elementId" and "document.forms[0].element".
Patterns are used for various reasons, e.g. to specify the expected value of an input field, or identify a select option. Selenium supports various types of pattern, including regular-expressions.

Selenium IDE 1.7.2

What is Selenium IDE ?

Selenium IDE (Integrated Development Environment) is a prototyping tool for building test scripts. It is a Firefox plugin and provides an easy-to-use interface for developing automated tests. Selenium IDE has a recording feature, which records user actions as they are performed and then exports them as a reusable script in one of many programming languages that can be later executed.

Even though Selenium IDE has a “Save” feature that allows users to keep the tests in a table-based format for later import and execution, it is not designed to run your test passes nor is it designed to build all the automated tests you will need. Specifically, Selenium IDE doesn’t provide iteration or conditional statements for test scripts. Selenium IDE is simply intended as a rapid prototyping tool

What is Selenium Automation Testing Tool ?

Selenium is a automation testing tool whose primary job is to automate web applications for testing purposes

Selenium has the support of some of the largest web browser vendors like Firefox, Chrome, Safari, Internet Explorer etc. who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks.
