Selenium For Beginner's
Introduction to Selenium
What is Selenium?
Selenium is a free (open source) computerized testing suite for web applications crosswise over various programs and stages. It is very like HP Quick Test Pro (QTP now UFT) just that Selenium centers around mechanizing online applications. Testing done utilizing Selenium instrument is typically alluded as Selenium Testing.
Selenium isn't only a solitary instrument however a suite of software's, each taking into account diverse testing needs of an association. It has four parts.
- Selenium Integrated Development Environment (IDE)
- Selenium Remote Control (RC)
- Selenium Grid
Right now, Selenium RC and WebDriver are converged into a solitary structure to shape Selenium 2. Selenium 1, incidentally, alludes to Selenium RC.
Who created Selenium?
Since Selenium is an accumulation of various apparatuses, it had distinctive designers too. The following are the key people who influenced striking commitments to the Selenium To extend
Prologue to Selenium
Birth of Selenium Remote Control (Selenium RC)
Tragically; analyzers utilizing Selenium Core needed to Best Selenium Institute in Marathahalli Bangalore introduce the entire application under test and the web server all alone neighborhood PCs due to the limitations forced by a similar source approach. So another ThoughtWork's architect, Paul Hammant, chose to make a server that will go about as a HTTP intermediary to "trap" the program into trusting that Selenium Core and the web application being tried originated from a similar space. This framework ended up known as the Selenium Remote Control or Selenium 1.
Birth of Selenium Grid
Selenium Grid was produced by Patrick Lightbody to address the need of limiting test execution times however much as could be expected. He at first called the framework "Facilitated QA." It was equipped for catching program screen captures amid noteworthy stages, and furthermore of conveying Selenium charges to various machines at the same time.
Birth of Selenium IDE
Shinya Kasatani of Japan made Selenium IDE, a Firefox expansion that can mechanize the program through a record-and-playback highlight. He thought of this plan to additionally expand the speed in making experiments. He gave Selenium IDE to the Selenium Project in 2006.
Birth of WebDriver
Birth of Selenium 2
In 2008, the entire Selenium Team chose to combine WebDriver Selenium Training in Marathahalli Bangalore and Selenium RC to shape an all the more ground-breaking instrument called Selenium 2, with WebDriver being the center. At present, Selenium RC is as yet being created yet just in support mode. The majority of the Selenium Project's endeavors are currently centered around Selenium 2.
Things being what they are, Why the Name Selenium?
It originated from a joke which Jason broke one an opportunity to his group. Another mechanized testing structure was famous amid Selenium's advancement, and it was by the organization called Mercury Interactive (yes, the organization who initially made QTP before it was procured by HP). Since Selenium is a notable cure for Mercury harming, Jason recommended that name. His colleagues took it, thus that is the means by which we got the opportunity to ring this structure to the present.
Brief Introduction Selenium IDE
Selenium Integrated Development Environment (IDE) is the most straightforward structure in the Selenium suite and is the least demanding one to learn. It is a Firefox module that you can introduce as effectively as you can with different modules. Nonetheless, due to its effortlessness, Selenium IDE should just be utilized as a prototyping apparatus. On the off chance that you need to make further developed experiments, you should utilize either Selenium RC or WebDriver.
Brief Introduction Selenium Remote Control (Selenium RC)
Selenium RC was the leader testing system of the entire Selenium venture for quite a while. This is the principal mechanized web testing device that enabled clients to utilize a programming dialect they lean toward. As of variant 2.25.0, RC can bolster the accompanying programming dialects:
Brief Introduction WebDriver
The upheld dialects are the same as those in Selenium RC.
Selenium Grid is an instrument utilized together with Selenium RC to run parallel tests crosswise over various machines and distinctive programs all in the meantime. Parallel execution implies running numerous tests without a moment's delay.
Empowers synchronous running of tests in numerous programs and situations.
Spares time gigantically. Uses the center point and-hubs idea. The center point goes about as a focal wellspring of Selenium charges to every hub associated with it.
