What is Selenium?
An open-source program called Selenium automates web browsers. It offers a single interface that enables you to create test scripts in several different programming languages, including Ruby, Java, NodeJS, PHP, Perl, Python, and C#.
Since then, Selenium has gained widespread adoption as the de facto standard for online browser automation, with millions of downloads annually. Selenium is generally used for automated testing but may also be used for browser automation activities like web scraping. Selenium is your tool if you need to automate any form of web browser interaction.
Why do I need to test using Selenium automation?
Consider a case where a human tester must determine whether the web app’s signup page (www.example.com/signup) correctly registers a user and validates input strings in the most recent releases of Chrome and Firefox on Windows 7.
Assume the username, email address, and password boxes are on the signup page. The test subject will receive a Windows 7 desktop and do the following actions sequentially in the most recent Chrome and Firefox versions:
- Enter the URL (www.example.com/signup) in the address bar.
- Fill out each input field with an erroneous string (email, username, and password)
- Verify that the input strings were compared to the corresponding regexes and any existing database values.
- Fill out each input field with “legal” strings, then click Join Now.
- Verify if the “Welcome, ‘username'” page appeared.
- Verify whether a new userID for “username” was established in the system database.
- If it did, mark the test as “passed” and “failed” if the signup feature malfunctioned at any point during the trial.
- That system test is pretty elementary. To achieve the benchmarked compatibility standards, testers are more likely to examine all user workflows on www.example.com for issues on as many OS-browser combinations as necessary.
The number of human testers (and the thoroughness of the test cases) will determine how long it will take to verify that the web app is completely functional.
Modern product teams and developers cannot set aside so much time for testing, nor can they put off thorough testing to release quickly. This is why they use automation, driven by Selenium, to boost their testing.
What Types of Testing can be Automated with Selenium?
The following types of testing are frequently automated with Selenium:
Testing for compatibility:
Performed by QA experts or testers to make sure the web application satisfies performance standards on various browser-OS combinations. For instance, testing on multiple devices (desktop and mobile) to ensure the front-end is scalable (responsive); testing on multiple browsers to determine if video advertising displays as it should on the pages.
Performance evaluation:
QA experts/testers conduct several tests to ensure the project satisfies the stakeholders’ performance standards. The tester creates a script on several browsers and browser versions to see if all homepage items load in under two seconds.
Integrity checking:
Developers checked them to ensure that individually programmed units or modules that function independently also function together. For instance, the Parallel Test Calculator contains distinct levels. The output is calculated by business logic and sent back to the UI for display when the UI receives the input. The tester might confirm whether they can relay data or output if they are integrated.
System evaluation:
QA/Testing experts perform black Box testing without knowledge of the code or any previously run tests. Usually concentrated on the workflow of a single user. Before being redirected to the bank website, the checkout procedure on a product website, for instance, entails authenticating user credentials, retrieving products from the cart, verifying their availability, and validating payment details. To ensure that the entire system is operational, the tester could build a script.
Testing from end to end:
She is also performed by testers and QA experts, often from the user’s perspective. The objective is to confirm the functionality of every web app touchpoint. The tester might create a set of test cases based on the previous illustration to ensure that the signup, product search, checkout, review, bookmark, and all other features work as planned (and fail when invalid values are entered in input fields).
Testing for Regression:
A series of tests were conducted to confirm that newly developed features are compatible with the current system. Let’s use the same example to illustrate a new feature (promotional codes) that the product website introduces and automatically applies to qualifying items before checkout. The tester could create cases to ensure it doesn’t affect the rest of the checkout feature.
Career Opportunities In Selenium for 2022:
You’ve come to the perfect website if you’re considering working in the web testing sector. We will educate you about the many Selenium employment options available to qualified testers and pros. Selenium web tests are becoming one of the critical components for many firms due to the rising demand for them.
Selenium is unquestionably one of the best tools for helping developers create more effective web tests if there is such a thing. As a result, using Selenium web testers is becoming more and more necessary, and this trend is expected to continue.
According to Business Wire, Selenium was the most in-demand web testing technology, driving an astonishing surge of 300 percent in job posts over the previous three years.
Multiple-Browser Support:
Selenium enables web automation by working with a wide range of popular browsers. The.xml file that maps to the Test Cases in the.java file can be created using the test framework TestNG. This makes the program operates as intended across all browsers. This enables many users to access the web application through their preferred browser.
An enhanced API that is simple to locate is Selenium WebDriver. REST and SOAP are the two main frameworks on which most APIs are based. We can use the SOAP user interface to test the API; for instance, if the API we want to try is built using SOAP and we want to check it out.
Selenium testing is a crucial talent for the growth of the software industry, particularly in countries where the snowball effect is visible in the vacant positions and pay scales, such as Australia, the UK, India, and the US.
WebDriver:
Selenium is the first to come up when discussing which testing framework is the most effective. Due to developers’ widespread use of Selenium worldwide, it is one of the most well-liked automation testing frameworks. The Selenium Course is a superior resource for learning this.
Non-Privatized Software:
Selenium is a free and open-source utility that may be downloaded. There are no up-front expenses for developers to use it. So, we may cut costs. By modifying its code with Selenium, you may better control it and get better results from the built-in classes and functions. Because it can generate test scripts, Selenium WebDriver is a well-known web automation framework.
Three explanations for using Selenium in 2022:
- Selenium has once more demonstrated its dependability, and this year will only increase its popularity.
- Those who have chosen to pursue Software Testing with Selenium will benefit from a wide range of job prospects.
- In the past three years, selenium job growth has increased by over 300%, and there are no signs that it will slow down or stop.
Preferable abilities:
- working knowledge of code versioning technologies like Git
- working knowledge of IDEs like Eclipse
- Understanding of TDD (test-driven development) and BDD (test-driven development)
- knowledge of CI/CD workflows and tools like Jenkins
- excellent ability to solve problems
- a capacity for both independent and teamwork
Future Scope Of Selenium: Major Companies Hiring Selenium Testers:
The best tool for automating web-based applications is Selenium. Test engineers and developers have used it more frequently in recent years. Selenium testers will be in greater demand as the software industry expands.
Major corporations like Google, Facebook, and Amazon employ Selenium testers. Big businesses like Barclays, HSBC, Accenture, Microsoft, and others use Selenium. Selenium testers will continue to be in demand in the upcoming years due to the software industry’s explosive growth.
