Selenium Testing Engineers Hiring Guide

QA Testing in the Modern Age

Any quality assurance (QA) engineer knows how time-consuming, inefficient, and repetitive manual testing is. That was the reasoning behind Jason Huggins’ initial creation of Selenium in the early 21st century. Initially called “JavaScriptTestRunner,” Selenium would later become Selenium Core, eventually evolving into the comprehensive, automated testing framework it is today.

The web application testing tool is used across a wide variety of industries and by major companies like Google, Alibaba, LinkedIn, Accenture, Penguin Random House, and many others. If you’re in search of a high-quality, skilled QA engineer with experience working with Selenium, here’s what you should know.

What Is Selenium?

Selenium is an open-source framework used to automate the testing of web applications. Intended to make the testing process quicker and more efficient than manual testing, it has become a fundamental part of the software development lifecycle (SDLC). You can use multiple languages with it: JavaScript, Python, Java, Ruby, PHP, and C#, to name a few.

Selenium was the first tool of its kind to be applied to a browser. After its initial development, other engineers began addressing some of the drawbacks to the Selenium testing process. Today, the automated testing framework consists of 4 main components:

  • Selenium Integrated Development Environment (IDE)
  • Selenium Remote Control (RC)
  • Selenium WebDriver: API, Library
  • Selenium Grid

Together, these tools make up the Selenium suite.


How Difficult Is It to Find a Skilled Selenium Tester?

Although Selenium has a fairly steep learning curve, particularly if you’re attempting to learn it without guidance, there are plenty of materials and resources available to help you become accustomed to it. And once a QA engineer has learned how to use this web application testing framework, it’s relatively simple to run. Moreover, a deep knowledge of programming languages isn’t required, although it will prove helpful.

Selenium is widely used, and you can feel rest assured that most seasoned QA engineers and testers you’re considering hiring have extensive experience using the framework — although you should, of course, verify that knowledge. That means that you shouldn’t have much problem finding a Selenium tester.


What to Look for in a Selenium Tester

Experience is the first quality to look for in a candidate. Because Selenium is only used for web application testing, if you’d like the prospective hire to work with other projects, such as mobile applications, then they will need to have experience with additional testing tools and frameworks.

Other qualities and skills to look for include:

  • At least a basic knowledge of programming languages
  • Soft skills like analytical thinking, problem-solving, collaboration, communication
  • Ability to interact with the developers and report bugs and other issues
  • Manual testing competencies
  • Test scripting
  • Experience with different types of testing — functional, performance, etc.
  • Experience working within your desired development methodology, especially agile
  • Curiosity and eagerness to learn

Additionally, make sure any candidate is aware of the top trends and goings-on in the testing field. QA professionals should stay up to date on best practices and news.

What are the advantages of using Selenium?

Selenium is one of the most popular testing tools out there, and with good reason. For one, it’s open-source, meaning that the costs associated with using it are lower. It can also be used for a wide variety of testing purposes and with all major browsers and operating systems, along with a number of programming languages.

Selenium has a huge community, too, lending support and resources to testers who encounter issues or need help.


What types of testing can you do with Selenium?

Selenium allows QA specialists to perform many different types of testing. Just some examples are:

  • Acceptance
  • Functional
  • Load
  • Performance
  • Regression
  • Sanity
  • Smoke
  • Stress
  • UI

How does QA testing fit into the Agile SDLC?

Agile depends on collaboration and quality. It also seeks to constantly improve products to be even better versions of themselves. Because the focus is on satisfying the consumer, QA testers enter the development process early on. They play a critical role in the process, conducting tests of modules to ensure their quality as early as possible. This is repeated several times.


What browsers does Selenium support?

According to the developer site, Selenium supports the following browsers:

  • Chromium, all versions
  • Edge, versions 84 and newer
  • Internet Explorer, versions 6 and newer
  • Mozilla Firefox, versions 54 and newer
  • Opera, versions 10.5 and newer
  • Safari, versions 10 and newer

When can you not use Selenium? What are some disadvantages of using the framework?

Selenium can only be used to support the development of web applications. That is, you can’t test mobile applications or any other types of software aside from web-based products.

There are some other drawbacks to relying on Selenium. For example, the tool demands that the tester have some coding knowledge, which isn’t always a prerequisite for QA specialists. Moreover, because it’s an open-source framework, users don’t have tech support from the developer, although there is a substantial community that offers support.


What is Selenese?

Selenese is the name of the language testers use to create commands in Selenium. These commands tell the framework what to do.
