how and when to use selenium testing software

What's Selenium?

What's Selenium?

Selenium, an open-source tool for testing web applications, is very popular. It enables testers to build automated tests in various programming languages to validate a web application's functionality.

Selenium is compatible with a variety of operating systems and browsers. Web application testing can be automated using the Selenium Testing Tool. It can be used to test how well web applications work in various browsers and operating systems.

Web application testing can be automated with Selenium software testing.

Components Of Selenium

Components Of Selenium

Selenium is made up of three main components:

Selenium Ide: A Firefox add-on called Selenium Ide enables testers to record and replay automated tests.

It is simple to design and run automated tests rapidly with Selenium IDE. A built-in debugger is also included with Selenium Chrome, enabling you to troubleshoot and fix errors in your tests.

To utilize Selenium, you must first install the add-on for Chrome or Firefox. To launch Selenium IDE, click the "Selenium" icon in the toolbar of Firefox or Chrome.

To start recording your tests after opening Selenium IDE, click the "Record" button. Selenium will start capturing all of your browser activity.

To stop the test recording, click the "Stop" button. Your tests can be replayed by selecting the "Play" button. The actions you have captured will then all be played back by Selenium.

Selenium WebDriver: Selenium WebDriver is an open-source application that automates user interaction with web browsers.

You can design tests using Selenium WebDriver that mimic user interaction with a web application. Python, Java, C#, and many other programming languages can be utilized with Selenium WebDriver.

WebDriver is a flexible and powerful test automation tool that allows you to create automated tests for web applications quickly.

You can also capture screenshots and automatically discover elements on web pages.

Selenium Grid: You can spread your tests across various physical and virtual machines with Selenium Grid (VMs).

Selenium Grid allows you to run parallel tests on multiple devices or virtual machines (VMs), allowing you to scale up your automation. The Selenium testing suite would only be complete with Selenium Grid. Your automated tests will be able to run significantly more quickly as a result.

The Selenium Server from Selenium Grid can be hosted on your device or a different server or system.

What Does Selenium Do?

Selenium WebDriver emulates the actions of users. Selenium WebDriver works by mimicking the actions of a user. You could create a Selenium test that prompts you to input your username and password in the relevant boxes before clicking the login button if you want to test the login function.

The activities would be carried out via Selenium, indicating any browser issues.

Benefits Of Using Selenium For Automated Test

Benefits Of Using Selenium For Automated Test

Language And Framework Support

When choosing a tool, someone first thinks of it: "Does it support the language I speak?" All popular languages, including Java, Python, and JavaScript, are supported by Selenium.

Your scripts can quickly be converted by Selenium into code that is compatible with it. Languages specific to Selenium are not required. Every Selenium-supported language comes with a dedicated framework that allows you to write Selenium test scripts.

Selenium is a tool that automates automation testing. Support for frameworks and languages is not a concern.

Open Source Availability

Selenium's open-source nature is one of its many advantages. Selenium, an open-source tool, is free and available to all.

You can save money and put them to good use. The Selenium community can assist developers and software engineers to automate web browser capabilities and functions.

Because Selenium is open-source, you can alter the code and enhance the performance of built-in classes and functions. Selenium is the most excellent web automation tool because it is simple to write test scripts that verify functionality.

Multi-Browser Support

The "One Selenium code for all real browsers" Selenium script was developed and improved by the Selenium community.

The Selenium script can be used with all of these browsers. It doesn't matter if you rewrite the scripts for each browser. For all browsers, a single hand is adequate.

Support Across Various Operating Systems

Different people utilize various operating systems. Your automation tool must be able to support each of them. On Windows, Linux, and Mac OS, Selenium can be used.

Selenium can create test suites on any platform, such as Windows. Nevertheless, the same suite can also be used with a different operating system, such as Mac or Linux. Software developers and testers can write test automation scripts that aren't very concerned with the platform they'll be running on.

Easy Implementation

The Selenium automation framework is relatively easy to use. Selenium has a simple interface that makes it easy to create and execute test programs quickly and efficiently.

You can even monitor the tests as they are being implemented. You can view detailed reports on Selenium tests and make follow-up decisions. Lastly, you will feel safe. Selenium has a large community available to assist you whenever you need it.

The community is open to all questions and brainstorming.

Reusability And Integration

As mentioned previously, selenium automation suites can be reused and tested on multiple operating systems and browsers.

What makes Selenium unique is that it does not offer a complete web automation tool. To increase the testing scope, third-party frameworks or add-ons are required.

To organize test cases and produce reports using Selenium, TestNG, JUnit, and TestNG must be combined. Integrating testing with CI/CD platforms like Jenkins, Maven, and Docker will enable continuous testing.

Selenium must be incorporated with Sikuli and cloud-grid to perform image-based testing. Selenium can be integrated with nearly all management tools.

Flexibility

It is the testing lifecycle's most crucial component. It is made simpler and more effective by Selenium's functionality, such as regrouping and restructuring test cases.

As a result, developers and testers may make code changes quickly. It lessens complexities, cuts down on duplication, and enhances maintainability. Selenium has an advantage over other automation testing solutions since it is more adaptable and user-friendly.

Parallel Testing Execution And Faster Get-To-Market

Saving time and effort is the main objective of automated testing. Selenium Grid allows us to run several tests simultaneously, speeding up test execution.

For cross-browser testing, cloud grids are employed. Selenium can be used to test simultaneously across a large number of browsers. This saves you time and effort.

Use Less Hardware

Selenium is less expensive than other vendor-focused automation tools such as UFT, QTP, and SilkTest.

It Is Easy To Learn And Use

Writing lengthy, intricate algorithms for selenium scripts is optional. Selenium scripts are a group of lines of code used to automate your website's operations.

The guide will be helpful for developers and testers to get started with Selenium automation testing. Selenium tutorials and testing are available via Google. You may also utilize the record and play features of the Selenium IDE plugin for the Firefox browser to construct Selenium scripts that can be used as a reference in the future.

Constant Updates

A community supports and upholds Selenium. Since we all know that vibrant communities prefer to stay active, the Selenium community frequently releases new features and updates.

These upgrades are easy to access and understand, which is the best thing about Selenium. Selenium is more resourceful than other tools, and it's also cost-effective. Hiring an Offshore Selenium Testers is the best option to get all the benefits.

What Is Selenium Automation Testing?

What Is Selenium Automation Testing?

Consider a scenario where a human tester must examine if the signup page for a web application correctly registered users and verifies input strings on Windows 7 using the most recent versions of Chrome and Firefox.

The registration form asks for your username, email address, and password. The tester will then have access to a Windows 7 desktop. Then, they will need to follow the steps on Firefox and Chrome:

  1. Enter the URL (www.example.com/signup) in the address bar.
  2. Enter a false string into each field (email, username, or password).
  3. Check whether the input strings have been checked against the relevant regexes and any previously stored data.
  4. To fill out each field with a valid string, click Sign up.
  5. Check whether the "Welcome" page of the "username'' was displayed}.
  6. Check if a new user with the "username" has been generated in the system database.
  7. Mark the test as successful if it passes.

    If the signup function is unsuccessful, mark it as failed.

This system test is fundamental. To find any issues, testers will more frequently test all user workflows at www.example.com in the actual world.

To ensure the system complies with the benchmarked compatibility standards, they may test as many OS-browser combinations as necessary.

It can take up to two weeks to ensure that the web application is functional, depending on how many manual testers are involved and the thoroughness of the test cases.

Modern product teams and developers need more time or resources for testing. However, they also need to pay attention to testing when it's urgent to release. Selenium is used to automate their testing.

How Selenium Testing Can Boost Agile Development

How Selenium Testing Can Boost Agile Development

What Is Agile?

An approach to creating software is called agile. Agile begins with the most basic iteration of the product concept, and iterations can be made over time.

Here's an example of an Agile workflow:

  • The product's most straightforward design is agreed upon by all stakeholders.
  • The design is broken up into more manageable components.
  • A cross-functional team of designers, developers, and quality assurance staff is tasked with working on each module.
  • Teams construct their modules during sprints, which have an iteration span of one to four weeks.
  • After each iteration, the modules are put together.

    Testing is performed, and the functional product with minimal bugs is presented to the stakeholders.

  • Stakeholders assess project priorities, get customer input, and make necessary adjustments.

The cycle repeats with the next iteration and a fresh set of modules. Multiple iterations are necessary for a product or feature that is market-ready.

Testing Automation Is Where It All Begins

  • QAs participate in the early stages of development to perform a series of acceptance and unit tests on modules.
  • Every iteration includes integration tests to ensure that modules with different codes don't fail when combined.
  • Every new iteration must pass regression tests to ensure that it doesn't invalidate any previously successful iterations.

To enable documentation of all iterations, it is crucial to keep track of the test cases and the source code. All subcategories of agile, quick, iterative development, including CI/CD, share the notion of frequent testing.

Selenium Testing Is Integral To Continuous Integration/Delivery (CI/CD)

What is CI/CD?: Continuous Integration/Release is a top priority for the speedy and frequent delivery of new builds.

After launch, a project is available for ongoing iterations (like Agile). The only difference is that the project can be shipped immediately rather than waiting for iterations.

This is How a CI/CD Pipeline Looks:

  • The project's developers wish to include the code they have.
  • An "integration test" is performed by an external CI server.

    It attempts to build the new code after grabbing the source files.

  • The server bundles the modifications with the source files if the build is successful.

    The server notifies team members if the build fails.

Dashboards for CI engines like Bamboo and Jenkins display recent and prior builds, check-in logs, the status (successful/failed), and what went wrong (and when).

Any modifications to the code, infrastructure, or configuration are communicated to everyone. This allows for early detection and fixing of deployment problems.

Automated functionality, efficiency, compatibility, and other testing are done with Selenium. Developers get near-instant feedback, allowing them to debug faster and allowing them more time to develop business logic for newer features/versions.

Modern web development requires Selenium testing because:

  • Testing smaller components of big(r) code bases is automated.
  • Agile software development, CI/CD, and agile development depend on it.
  • This saves time and money on manual testing.
  • It is trustworthy and capable of finding bugs that human testers might overlook.
  • It can offer extensive coverage for testing.
  • It is precise, and customized error reporting is an added benefit.
  • It can be reused; every new feature is deployed, and you can refactor the test script.
  • It is scalable.

    Over time you can build an extensive library of repeatable product test cases.

This technology enables the recording and replay of machine-learning-enabled test automation on actual desktop browsers.

Headless Browser Testing

Testing on headless browsers provides developers with quick feedback. Mozilla and Google Puppeteer are two examples.

Headless browser testing is easy to set up and increases test coverage.

Additional Tools And Frameworks

Selenium is one of many test tools. However, it forms the foundation for many other frameworks. For instance, Protractor was developed on top of Selenium to enable application testing of an AngularJS application.

Selenium can be integrated with all things. Use Selenium's additional testing tools in the following situations:

  • It would help if you offered a testing framework (BDD/ATDD).
  • Assertion functions (Chai.

    Jasmine.

    Jest.

    Unexpected).

  • Display, produce, and keep track of test results (Mocha Jasmine Jest, Karma).
  • Create reports on code coverage (Istanbul Jest, Blanket).
  • Give scenario execution and UI testing access to a browser or browser-like environment.
  • Offer mocks, spies, and ticket stubs (Sinon Jasmine enzyme, Jest test double),

Overall Strategy

You should consider your overall test automation plan as well. To be successful, you will need to combine these frameworks, including codeless and cross-browser coding-based frameworks.

Lastly, you can ask these questions:

  • Is the test automation framework capable of taking screenshots?
  • Is it possible to do performance and memory profiling?
  • Do you have the ability to provide coverage analysis for test results?
  • What are testing types available?
  • Is it compatible with your software development lifecycle (SDLC)?
  • How dependable and effective is the framework?
  • It can support page object modeling creation
  • What characteristics of this test automation framework are synchronized and asynchronous?
  • Is it available with a team of reporters?

These inquiries are critical today, especially if you have a responsive or progressive online application.
