Selenium is a tool that is used to test web applications. The Selenium testing framework works directly with browsers. Supported browsers include Mozilla Firefox, Safari, Google Chrome, Opera, Edge, and Internet Explorer versions 7, 8, 9, 10, and 11.

The following are the main goals of this tool: testing for browser compatibility; evaluating software to see whether it can function properly on different operating systems and browsers.

You should test the system’s functionality and create regression tests to ensure the final product meets user expectations. Support automatic action recording and the creation of test scripts using several languages, such as Perl, Java, and Net.

What are the advantages of using Selenium in such broad applications, and why is it used in them?

JavaScript is used in the framework’s basic layer to mimic the behaviors of actual users and manipulate the browser. When the test script is executed, the browser will automatically perform several actions according to the script code, such as clicking, entering, opening, validating, and more.

The applications should be tested from the end user’s point of view. Even though different browsers have small differences that set them apart from one another, this will allow automation of testing for browser compatibility.

  • There are many languages in which use case scripts can be created, including Java, Python, and others. The software is easy to use.
  • Using the Selenium framework by commercial enterprises is not restricted in any way and is open-source. In addition to educational documents, it facilitates diffusion and has a strong community.
  • Selenium tests can be run on Windows, Macintosh and Linux Computers using Internet Explorer, Firefox and Chrome. This is the only testing method to accommodate such a wide range of systems. Using Selenium and running tests within browsers has a ton of additional benefits.
  • Use case scripts are extremely easy to use and may be created in several languages, including Python, Java, Ruby, Perl, PHP, and C#.
  • For Windows, macOS, and Linux, build environments are provided for Selenium testing.
  • Continuous integration and continuous delivery (CI/CD) can be achieved with the help of Selenium integration with Maven, Jenkins, and Docker.
  • Additionally, it can communicate with other test management technologies like JUnit and TestNG.
  • By creating Selenium test scripts that mimic user operations, you may test apps from the end user’s viewpoint.
  • It is considerably easier to find browser incompatibilities when testing is conducted across various browsers. The core of Selenium, popularly known as the browser BOT, is written in JavaScript. Thanks to this, test scripts can now function in browsers that support them. The task of the browser BOT is to execute the commands given to it by the test script. The test script may be written in a supported programming language or an HTML table layout.

Things to know for writing the best Selenium scripts:

  • Ensure that the Right Locators Are Used:

Selenium uses pre-built actions to connect with the browser. There are locators in the following categories:

  • LinkText
  • ID
  • Class
  • XPath
  • Tag Name
  • PartPartial Link Textial

When dealing with Selenium, it is advisable to use unique class names or IDs as locators because they are rarely updated. However, locators like link text can be changed whenever you want.

For instance, dynamic buttons can change depending on whether the user is signed in, and your marketing team can do A/B tests. Avoid using XPath navigation unless it is necessary.

  • The browser’s zoom setting needs to be set to 100%:

Likely, some test scripts won’t function properly during Selenium test automation on some browsers. This problem occurs when running cross-browser tests on outdated browsers like Internet Explorer.

The Protected Mode Settings (in Internet Explorer) for each zone must be the same in addition to this setting. If not, you can get a message with the subject “NoSuchWindowException.”

  • Extend the browser window to its maximum size:

To ensure that the test report’s web page style is constant throughout. To ensure that a screenshot of the entire website is taken, it is advisable to maximize the browser window as soon as the test URL loads. (Selenium does not start browser windows in the maximized mode by default).

  • Implement Code Dependency Correctly:

It is proposed that operation methods and dependency files be built independently to maintain the values that must be provided. The code will become more universal as a result, and it will also be simpler to update, especially for testing across many browser versions.

How Should Test Scripts be Written in Selenium?

You can visit the official website of Selenium to create your Selenium test environment. How you design and set up WebDriver depends on the programming language environment you intend to use with your tests. The most popular operating system is installed-ready and pre-packaged.

The Selenium Selenium Suite of Tools Installation Basics:

  • RC selenium (Deprecated from Selenium V3 onwards)
  • Selenium WebDriver
  • Selenium Grid,
  • Selenium IDE.

 We will not even introduce Selenium RC because it needs to be updated. The following will be a description of the final three instruments:

  • Selenium IDE (Integrated Development Environment)

The Selenium IDE is your best choice if you want to build issue reproduction scripts to help automate assisted exploratory testing. This application makes it simple for Chrome, Firefox, and Edge plug-ins to record and replay browser interactions.

One benefit of using the Selenium IDE is exporting tests created by plug-ins in various programming languages, including Java, Ruby, and Python.

  • Selenium Grid:

You can use a Selenium grid if you want to distribute and run tests on several machines quickly, extend and manage various environments, and run tests against various browsers and operating systems.

To execute the automation scripts you wrote using Selenium, you can access the online Selenium grid offered by several websites. 

  • Selenium WebDriver:

This capability allows you to extend and share scripts in various environments. This allows for the creation of regression automation tests and browser-based tests. Selenium WebDriver is known to be a huge library of language-specific bindings for driving the browser.

The Most Common Problems with Selenium Scripts and How to Fix Them?

  • Scalability:

When used in different browsers, web apps behave differently in several ways. Even if the Selenium web driver permits testing on several operating systems and browser versions, the testing efficiency might not be at its best because of the constrained testers and test threads.

Additionally, Selenium may only run tests in a specific order at once. Parallel testing can reduce some of the stress brought on by this problem.

  • Taking Care of Dynamic Elements

Selenium-based automated testing of dynamic web apps is quite risky for various reasons. One of them is that locators occasionally fail to connect with web components. Another reason for the test script’s poor performance may be that Ajax-based web content loading occasionally requires some time.

  • Steps in Order

If the scheduled events didn’t occur for reasons that needed clarification, the Web tests’ sequencing might become problematic. Often waiting features are employed and are defined in Selenium, such as implicit waiting and explicit waiting, to address this problem.

  • Unreliable Positive or Negative Interpretations of Results:

False positives are errors during test scenarios even though the web application under test is normally operational. Similar to a false positive, a false negative describes a positive test case result even when the application under test has encountered a problem.

As a result, the testing team will receive inaccurate information, and communication between the QA and development teams will be more challenging. To deal with test instability, automated testers have a challenging problem.

We must make sure that our test strategies, test cases, and environments are managed effectively and efficiently to overcome this unpredictability.

  • Handling of Pop-Up and Alerts:

Several types of pop-up windows and warnings may occur while engaging with a web application; the following is a list of some of these:

  • Browser level, notification: permit or deny the download. Different browsers have different handling requirements for pop-ups at the browser level. Browsers that run Chrome can provide you with chrome options. Firefox profiles and settings pages can be used to personalize Firefox browsers.
  • OS-level pop-ups: Selenium’s capabilities are solely constrained by online interactions.
  • Page Alert: A page with a warning that reads, “you will be redirected to another website,” or something comparable The predefined “alerts” class that is included with Selenium can be used to manage this type of alert. There are numerous methods available in this class, including accept (), refuse (), and others.
  • OTP or a Captcha:

It is difficult for the automated test workers to verify whether the OTP and user access code for verification; the content mechanism should be to check the robot operations.

  • Mobile Testing:

More and more people are willing to use their mobile devices to access web apps rather than home computers. Testing using Selenium is almost impossible because there are so many different mobile devices available (each with its operating system, version, screen resolution, etc.).

How to Set up an automated selenium test suite on your mac?

Going ahead, we will be how we can install Selenium Python on Mac OS:

The automation script’s speed is increased and may be reused via Selenium’s Integrated Development Environment (IDE). As a result, you can do automated testing across various browsers using a single script.

For engineers with little coding knowledge, it is also straightforward to learn. All languages, including Python, Java, and C#, are supported by the Selenium scripts.

Additionally, the Selenium Grid enables the concurrent parallel execution of test cases across numerous browsers and operating systems. Because of this grid, the test’s execution time is reduced.

Additionally, Selenium is easily integrated with other testing tools like Maven, Docker, and Jenkins. Connecting Selenium with test management systems like Junit and TestNG is also easy.

Python is an open-source scripting language that is simpler to learn than other computer languages and is, therefore, easier to use. It provides a default framework called PyUnit or Unittest for automated testing.

Also, it comes with built-in testing frameworks like Robot and Pytest. It can also easily be coupled with other programming languages, such as C, Java, C++, and others.

What benefits do Python-based automation systems have over Selenium-based ones?

Automation testing is transforming manual test cases into automated test scripts using technologies for automation, such as Selenium. The main benefit of using automation is that it works more quickly and saves time.

Using this combination for automation is a good decision because both support cross-browser testing. Selenium Python is the preferred tool for automating testing as a result.

Installation of selenium Test suite on Mac OS:

Using macOS can allow you to avail yourself of the benefit that the OS already has Python installed by default.

  • To proceed further, the user must verify the Python installation via commands.
  • To install selenium Python, a PIP, i.e., Package Installer for Python, is required. It is also known as the package management system specialized for Python. Install it and then verify it on your macOS.
  • Now you can open the terminal for installing Selenium and run the required command.
  • On execution of the above steps, a folder called selenium will be created under the Python folder.
  • Now the existing version of Selenium needs to be updated. On completing the last step, your macOS is ready with the Selenium Python.

What is the best way to use Python and Selenium together?

If we use a Configuration File, we can use Python to install Selenium. Regarding: When we mention “configuration,” we mean “settings.” In plain English, the configuration file contains the details about the infrastructures and setup of our program. In addition, we used the term “Config File” to describe it.

It stores all of the information related to our interactions with the application’s user interface or UI. Consequently, we need it. 

The configuration file has the following functions in the Selenium Python framework: 

Role of the config file in Selenium Python: Selenium configuration files store data about various potential browsers and devices inside themselves. Selenium is used in the automation process to perform cross-browser testing.

Using Python and Selenium for Automation: Selenium is used in the automation field to test several common procedures. They include opening a website, browsing through it, pressing keys, selecting clickable elements, and other similar tasks.
