10. How To Test PDF Files Using Selenium Automation?

PDF documents are small-sized, highly secure files. Almost all businesses use PDFs for processing their files, the reason being a distinguishing feature of maintaining format regardless of the tool used to access PDF files. It’s no surprise that all our invoices, official documents, contractual documents, boarding pass, bank statements, etc., are usually in PDF format.

Even if you are a developer, you’ll come across scenarios when a PDF file needs to be verified or used to locate certain parts of data. You can either do this manually if you have time to spare or opt for automation testing. When it comes to handling tricky components of such files using automation, it might seem a bit too tricky. But that’s not the case. Selenium test automation can make it easy to test PDF file formats.

In this blog post, we will be exploring the knotty topic of Selenium testing PDF files and come up with different solutions to handle a PDF document using automation. This post about Selenium testing PDF files explained everything about using Apache PDFBox, using PDFTextStripper, and using TestNG asserts. From extracting content from a specific page to validating its content, you can perform all those operations in LambdaTest.

9. Cypress Vs Selenium: How To Pick The Right Testing Tool For You?

Selenium is one of the most prominent automation frameworks for functional testing and web app testing. Automation testers who use Selenium can run tests across different browser and platform combinations by leveraging an online Selenium Grid. Though Selenium is the go-to framework for test automation, Cypress — a relatively late entrant in the test automation game has been catching up at a breakneck pace. Like Selenium, Cypress is also an open-source test automation framework for testing web applications. And that’s where the big Cypress vs Selenium fight begins!

In this blog, we have done a detailed Cypress vs. Selenium comparison to determine the core differences between Selenium and Cypress to make it easier for you to evaluate Cypress vs Selenium for your next test automation project!

5. Build An Automated Testing Pipeline With GitLab CI/CD & Selenium Grid

CI/CD has been gaining a lot of attraction & is probably one of the most talked topics for DevOps’ novices. With the availability of CI/CD tools available in the market, configuring and operating a CI/CD pipeline has become a lot easier than what it used to be 5–6 years ago.

In this article, we configured a CI/CD pipeline with GitLab CI/CD and executed Selenium testing over it through LambdaTest, an online Selenium Grid of 2000+ real browsers. With this, you can now successfully execute Selenium testing to perform all kinds of checks before the release gets deployed. GitLab CI prepares the release process for you, and it takes away all the hassle from doing those last-minute checks by allowing you to integrate with an online Selenium Grid of 2000+ real browsers, ensuring a seamless UI for your web-application.

This is how you can build a robust CI/CD pipeline for your company or team there.

4. How To Download & Upload Files Using Selenium With Java

While Selenium testing, you may have come across a requirement to either download or upload files in Selenium. Almost every web-application over the internet has a feature that allows users to either download or upload a file. Suppose you are an automation tester who has a routine set around Selenium testing. In that case, there is a good chance for you to run into a requirement where you may have to test a feature around downloading or uploading files in Selenium WebDriver.

Selenium testing can help you automate the download & upload file functionality of your web-application easily. Working on the upload file feature of Selenium is very easy if you have understood the difference between Remote WebDriver and WebDriver Interface. However, it is always recommended to go for a cloud-based Selenium Grid to save time and resources.
