Selenium IDE, Selenium 1.0, Selenium 2.0, Selenium RC, Selenium GRID, Web Driver and what not... Part 2

So we have seen, Selenium IDE, Core and RC in part 1 and its time to know a new booster in the offing for Selenium. By now you would have realized that Selenium greatly suffers from its own implementation design. It uses js to drive a page and suffers from js restriction in a browser. WebDriver originated as different web testing library, which tries to employ best possible solution for a automated tests in a browser. WebDriver for Firefox is implemented as Firefox extension, while for IE it makes use of IE's automation control. When facilities offered by Browser are not enough, WebDriver makes use of Operating System offerings. For example to type in file input box. WebDriver and Selenium are being merged to offer best of both API. They can not be exported to WebDriver overnight. How about the test which are already written in Selenium and WebDriver has solution for this also. WebDriver lets you write new test using WebDriver api, while yet supporting existing Selenium test using WebDriverBackedSelenium. for java client driver. WebDriver also supports headless (without head  without browser) execution of tests. Since there would not any browser interaction in this case so these tests would be faster than tests running on actual browser. But do you really want to sacrifice browser for sake of speed of tests ?

And we are still not happy with speed of test. We want to run tests on different browsers and all at the same time. Answer is Selenium GRID. One Selenium RC can also be used to invoke multiple browsers, but it would soon exhaust system resources. Grid works with Hub > Slave concept, where one hub (Selenium RC) controls slaves (more Selenium RCs) for invoking browsers on multiple systems.

At last about Selenium 1.0 and Selenium 2.0, Selenium Remote Control is referred as Selenium 1.0 while Selenium 2.0 is referred as merged Selenium and WebDriver api, which should be future Selenium. You may want to be loyal to Selenium 1.0 before while experimenting with Selenium 2.0 at the same time...

Verify email confirmation using Selenium WebDriver

Note: If you are new to java and selenium then start with selenium java training videos .   How to Verify Email Confirmation Using Selenium 4 and JavaMail (2026 Guide) Email confirmation is a critical part of most registration flows — account activation, password reset, multi-factor authentication, and onboarding. Every automation engineer eventually faces the same challenge: How do you verify an email confirmation link inside a Selenium test without making it slow and flaky? The wrong instinct is to automate Gmail's UI with Selenium. It's fragile, slow, and breaks constantly. The right approach: Use Selenium for browser automation Use JavaMail (IMAP) to read the email directly Extract the confirmation link Continue the test in Selenium Why Not Automate Gmail UI With Selenium? Automating the Gmail UI means logging in, searching, clicking a message, and parsing content from a third-party interface that changes frequently. This leads to: Flaky...

Using xPath to reach parent of an element

Note: If you are new to java and selenium then start with selenium java training videos .   I generally prefer CSS selectors over XPath when writing Selenium locators. CSS selectors are concise, readable, and usually provide everything I need. However, there are situations where XPath is a better fit—particularly when I need to navigate through an element's hierarchy, such as moving from an element to its parent, grandparent, or sibling. This post shows one such real-world example. The Problem I came across a situation where I needed to click a link based on the value of an input field. The HTML structure contained multiple similar groups of elements. The input field and the link I wanted to click were not directly related, but they shared a common parent structure. In the following example above, the input element is highlighted, and I need to click the corresponding anchor ( <a> ) element . The challenge is that there may be multiple similar structures on the page. I th...

Real Time JMeter Result Using Backend Listener

Since JMeter 2.13 Backend Listener has been available to create real time graph of JMeter Test. Following tutorial explain the entire process in detail. At the end of this tutorial you would be able to create JMeter Live Test Result dashboard similar to following - This tutorial borrows information from many sources and my own experiments with JMeter live reporting dashboard. I have added source of information wherever applicable But before we can build such a snazzy JMeter Live Reporting dashboard we need to understand two more components - influxDB (a time series database) and Grafana Dashboard This is a big tutorial, so take deep breath :-) and follow on. Once you complete set up specified in this tutorial then you can watch JMeter Training Video Tutorial to watch this in action. What is Time Series Database? A time series is a sequence of data points , typically consisting of successive measurements made over a time interval . Examples of time ...
