What is the difference between Selenium IDE and Selenium RC with its functionality?
回答1:
Selenium IDE is a firefox plugin that gives you a basic recorder for recording tests. These tests are recorded in an HTML table based architecture using keywords, and IDE gives you the ability to then export the code out to other languages (Java, .Net, PHP, Python, Ruby, or Perl).
Selenium RC is an API accessible from multiple languages. Rather than recording tests, you write programs that call into the API to control the browser.
You didn't ask, but Selenium WebDriver is Selenium 2.0's equivalent of RC. It's an API that is called from whatever language you're using (I believe it supports Java, .Net, Ruby, Python, and PHP_. This is a different API than that used in Selenium RC, but there are compatibilities built in to make the transition easier.
Most people find that having a full programming language available like you do with RC/Webdriver gives them much more power and flexibility. For example, conditional statements like if thens or loops are much easier to do in a programming language than in the HTML tables that IDE works with. Selenium 2 has just been released today.
I haven't used IDE in a while, but from what I remember, most of the actual API that Selenium provides is available in both the HTML keywords and the API functions, but the API is far easier to work with and make tests beyond the simpler ones that are recordable.

This article has a good explanation.
Selenium Core:
In 2004, Jason Huggins was testing an internal application at ThoughtWorks. Being a smart guy, he realized there were better uses of his time than manually stepping through the same tests with every change he made. He developed a JavaScript library that could drive interactions with the page, allowing him to automatically rerun tests against multiple browsers. He named this program as the JavaScriptTestRunner. Seeing potential in this idea to help automate other web applications, he made JavaScriptTestRunner open source which was later renamed as Selenium Core.
Selenium RC:
Unfortunately, to work within the Same Origin Policy, Selenium Core must be placed in the same origin as the Application Under Test (AUT). So another ThoughtWork’s engineer, Paul Hammant, created a server that would act as an HTTP proxy masking the AUT under a fictional URL, embedding Selenium Core and the set of tests and delivering them as if they were coming from the same origin. This system became known as the Selenium Remote Control (Selenium RC), or Selenium 1.
Selenium WebDriver:
In 2006 a plucky engineer at Google named Simon Stewart started work on a project he called WebDriver. Google had long been a heavy user of Selenium, but testers had to work around the limitations of the product. Simon wanted a testing tool that spoke directly to the browser using the “native” method for the browser and operating system, thus avoiding the restrictions of a sandboxed Javascript environment. All implementations of WebDriver that communicate with web browsers shall use a common wire protocol. This wire protocol defines a RESTful web service using JSON over HTTP.
Selenium IDE:
In order to further increase the speed in creating test cases, Shinya Kasatani of Japan created Selenium IDE, a Firefox extension providing an easy-to-use interface for developing automated tests. Selenium IDE has a recording feature, which captures 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. Selenium IDE was simply intended as a rapid prototyping tool. He donated Selenium IDE to the Selenium Project in 2006.

Selenium IDE is a firefox add-on. You are able to record/Edit/ play your test scripts. But unfortunately it supports only Firefox.
Selenium RC or the latest Web dirver it proivdes you an API to write your own test script. Also scripts can be written to test cross browser testing, to assert multiple languages (Junit, Nunit, TestNG, etc.,) and finally scripts can be taken to a Continuous Integration Environment
To maintain Selenium IDE scripts are very difficult. But Selenium RC / Webdirver test scripts maintainability or re usability is very easy

1 - The Selenium-IDE (Integrated Development Environment) is the tool you use to develop your Selenium test cases. It’s an easy-to-use Firefox plug-in and is generally the most efficient way to develop test cases. It also contains a context menu that allows you to first select a UI element from the browser’s currently displayed page and then select from a list of Selenium commands with parameters pre-defined according to the context of the selected UI element. This is not only a time-saver, but also an excellent way of learning Selenium script syntax.
2- Selenium RC was the main Selenium project for a long time, before the WebDriver/Selenium merge brought up Selenium 2, the newest and more powerful tool.
Selenium 1 is still actively supported (mostly in maintenance mode) and provides some features that may not be available in Selenium 2 for a while, including support for several languages (Java, Javascript, Ruby, PHP, Python, Perl and C#) and support for almost every browser out there.

Selenium RC is a Selenium server installed that will execute test scripts from that location. Selenium RC has the ability to use any of the supported server-side languages to write the test scripts which opens up a whole new set of error handling, scheduling, error notifying, and unit testing frameworks to use in conjunction with the Selenium core. It also supports the ability to execute the test scripts in varying browsers, where as the IDE currently only executes for Firefox.
回答6:
Selenium IDE works on only in Firefox where as selenium RC Support multiple browser. selenium RC using null session value.
