What exactly is selenium?

Selenium is an open-source web browser automation tool. It affords a single interface for writing test scripts in a variety of programming languages, including Ruby, Java, NodeJS, PHP, Perl, Python, and C#. Join Selenium Training in Chennai to learn more about Selenium Testing.

Selenium WebDriver:

WebDriver, also known as Selenium 2.0, runs test scripts using browser-specific drivers. It consists of the following components:

API:

API (Application Programming Interface) stands for Application Programming Interface. Through bindings, it converts test scripts written in Ruby, Java, Python, or C# to Selenese (Selenium’s own scripting language).

Library:

The API and language-specific bindings are stored in the library. Although there are various third-party bindings available to support various programming languages, the main project supports the following client-side bindings: Selenium Java (as selenium jar files), Selenium Ruby, Selenium dot net (or Selenium C#, available as.dll files), Selenium Python, and Selenium JavaScript (Node).

Driver:

Opens a browser instance and runs the test script with the Driver Executable module. Google, for example, creates and supports Chromedriver for Selenium to facilitate automation on Chromium/Chrome.

Framework:

Selenium with Cucumber or Selenium with TestNG are examples of framework support libraries for integration with natural or programming language test frameworks.

What is the purpose of Selenium Automation Testing?

Consider the following scenario for a manual tester: checking whether the web app’s signup page (www.xyz.com/signup) validates input strings and properly registers a user in the newest versions of Firefox on Windows 7 and Chrome.

Assume the signup page includes the following fields: username, email address, and password. On the latest versions of Firefox and Chrome, the tester will acquire a Windows 7 desktop and do the following steps in order:

  1. In the address bar, type (www.xyz.com/signup).
  2. In each input field, type an incorrect string (email, username, and password)
  3. Check to see if the input texts were checked against the database’s regexes and any pre-existing values.
  4. In each input field, type ‘valid’ strings; then click. Create an account
  5. Check to see if the page “Welcome, “username”” appeared.
  6. Check to see if a new userID for ‘‘username” was established in the system database.
  7. If it did, mark the test as a success; if the signup functionality broke at any point during the test, mark it as a failure.

That’s a fairly simple system check. In the real world, testers are more likely to test all user workflows on www.xyz.com for breakage across as many OS-browser combinations as necessary to fulfil the benchmarked compatibility standards.

It could take anywhere from hours to weeks to ensure that the web app is fully working, depending on the number of manual testers (and the quality of test cases).

Modern developers and product teams don’t have that amount of time to devote to testing, but they also can’t commit to thorough testing in order to meet a deadline. This is why they use Selenium-powered automation to boost their testing. So Join Selenium Online Course to enhance your knowledge in the Testing domain.
