How many of you have put your Thinking Cap on before writing a variable name? Well, I certainly do more often than not. If you are working on a big project, sometimes it becomes a tedious job to correct variable naming conventions among the team members.
In the case of UI test automation using Selenium or any other tools for that matter, it becomes way more complex to decide variable names for different web elements. Enough with the talks, let’s show you the chart that will help you distinguish between varieties of web elements and keep your sanity in check.

public WebElement loc_txtLastName;
Thank you for reading so far. Hope it was helpful in some way. Nonetheless, I will keep writing such articles based on my experience and knowledge that may help you with the day-to-day tasks as a Test Automation Engineer. Stay connected!
