3. How To Build An Automated Testing Pipeline With CircleCI & Selenium Grid
Continuous Integration and Continuous Deployment is a critical component of the software development lifecycle (SDLC) and is strongly linked to agile methodologies. The faster products are shipped to end-users, the more prominent will be a competitive advantage! However, complexity arises when the product delivery must be bug-free to sustain the customer experience. This is where automation testing comes into the picture, and when combined with deployment pipelines, the entire quality assurance process becomes seamless.
The best CI/CD tools like Jenkins, Travis CI, TeamCity, etc., help in these CI/CD procedures. CircleCI, on the other hand, integrates effectively with popular version control systems such as GitHub, GitLab, and others. CircleCI automates the build, testing, and deployment of apps, allowing quicker development and smoother collaboration between teams. This enables developers to confidently provide source code for the automation of the entire CI/CD process.
In this blog on building an automated testing pipeline with CircleCI & Selenium Grid, you will learn more about CircleCI, how to create a CircleCI pipeline, and how to execute automated testing on Cloud Selenium Grid using a CI/CD pipeline.
4. Selenium SendKeys: All You Need To Know
Selenium automation testing is more than just navigating and clicking on links. You can also use it to switch tabs, discover broken links, and drag & drop. Passing values to text fields is an integral part of test automation. For example, to input content into editable text fields or password fields on a webpage, Selenium provides the sendKeys() method. These fields are similar to the standard web elements found on a website and can be detected using Selenium locators.
5. How to Write Test Scripts in Selenium
Due to significant advancements in modern web automation frameworks, enterprises prefer Selenium for automated browser testing over other new frameworks like Cypress. In addition, Selenium has a diverse and sophisticated set of tools. As per the State of Open Source Survey, Selenium is still the go-to framework for automated browser testing.

7. Building A CI/CD Pipeline With Travis CI, Docker, And LambdaTest
Continuous Integration (CI) is the technique of constantly pushing small sets of code changes to the common integration branch rather than integrating all changes at once. This eliminates the need for a big-bang integration before a product release. Continuous Integration and Selenium test automation are essential software development life cycle components. As the benefits of implementing the DevOps technique in a development team become more apparent, teams have begun to use various tools and libraries, such as Travis CI with Docker, to carry out this activity.
Travis CI is a cloud-based tool for teams that allows them to develop and test apps. Travis CI, as a continuous integration platform, aids the development process by automatically building and testing code changes, delivering immediate feedback if the change is successful. It can also help us in automating other processes in the software development cycle, such as deployment and notification management.
In this tutorial on building CI/CD pipeline with Travis CI and Docker, we will look at the importance of Travis CI in Selenium test automation and how to use it with Docker with examples. In the end, we will automate Selenium tests with Travis CI on the LambdaTest cloud grid.
8. E2E Headless Browser Testing Using Nightwatch JS
Headless browsers are a feasible option for web app testing. Web browsers are an essential aspect of automation testing using Selenium WebDriver. Headless browsers are preferred in situations when the visuals do not need to be rendered. For example, they may not be suitable for surfing but can be an excellent tool for testing. During a Selenium automation test execution, Selenium runs the relevant browser defined in the script and then conducts test steps. However, difficulties such as slow web page rendering may cause the test execution pace to be delayed. Headless browser testing was introduced as a method to reduce test execution time.
In this post, we will discuss headless browser testing, its benefits and limitations, and also circumstances in which headless browser testing should be used or avoided. In addition, we will look at how to perform headless testing using Nightwatch.js. This will help you run tests in popular browsers in headless mode using the Nightwatch.js framework.
9. Parallel Testing With JUnit 5 And Selenium [Tutorial]
One of the key aspects that can influence test execution performance is parallel test execution with Selenium. Serial execution in Selenium automated testing is only useful if the tests should be run on a limited set of browser and operating system combinations. As a result, parallel execution should be used early in the QA process to accelerate test execution.
Though parallel testing with Selenium can be benefited by using a local Selenium Grid, it may not be a viable solution if you wish to test on a plethora of browsers, operating systems, and devices. This is where testing on a cloud-based Selenium Grid, such as LambdaTest, can be extremely beneficial. It can also help to accelerate parallel test execution by harnessing the Selenium Grid’s features. In this JUnit 5 tutorial, we’ll cover how to run parallel tests with JUnit 5 and Selenium in a variety of methods on the LambdaTest cloud grid that offers 3000 browser and operating system combinations.
10. How To Find Broken Images Using Selenium WebDriver?
A broken image is a link or image that does not appear as a picture, and clicking on it brings the user to a defunct image. One user clicks on the broken image and receives a 404 error. This error indicates that there is a problem with the image URL, and the image is not correctly loaded due to various reasons.
Fixing broken images on websites is just as important as fixing broken links in terms of end-user experience and retention. Broken images on web pages can be found using Selenium WebDriver. However, depending on how the images are fetched from the server, the internal logic for finding broken images may differ.
In this Selenium Tutorial, we’ll look at how to find broken images using Selenium WebDriver on websites. This will help you in finding broken images with Selenium WebDriver using programming languages like Python, Java, C#, and PHP.
