What Is Holding A Software Tester From Finding Bugs?

Every major product on the internet is trying to expand their reach to full potential by accomplishing the goal of Web Interoperability. According to which various Web technologies on the World Wide Web should be compatible with one another. Also, the technologies should be accessible through any hardware and software. Facilitating Web Interoperability has been a major impediment for Software testers as they play a key role in ensuring the quality of a web-app. Although, recently automation and machine learning are dawning upon the IT world and are over shadowing the role of testers. Especially, if we refer to manual testing. We often underestimate the scope of manual testing assuming that automation is going to take over everything. This is a big misconception, the point of automation is to save testers the time to write better and efficient test scripts. Manual testing is going to prevail in the industry.

A Detailed Guide To Blockchain Testing

From 2009, when Satoshi Nakamoto implemented blockchain technology as a core component in Bitcoin, blockchain has been the buzzword in the industry. Bitcoin’s success proved the capabilities of blockchain based transactions and and now everyone is planning to implement blockchain technology in almost everything. According to World Economic Forum survey, by 2027, 10% of the global GDP may be stored using none other than blockchain based technology. Interesting, isn’t it?

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 the novices in DevOps. 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 was 5-6 years ago. Back then there were no containers and the only CI/CD tool that dominated the sphere was Jenkins. Jenkins provided you with a task runner, so you could define your jobs to run either sequentially or in parallel.

How to perform Mouse Actions in Selenium WebDriver

A web product (or website) comprises multiple web elements like buttons, text boxes, checkboxes, menus, sliders, and more. During the process of Selenium automation testing of the website, you can realise specific scenarios by automating low-level interactions such as keypresses and mouse button actions (e.g. click, double click, right-click, etc.) with the WebElement(s) in the DOM. These interactions, also called Actions, play an integral part in testing an application using the Selenium framework.

CSS Grid Layout vs CSS Frameworks: When To Use What?

“CSS Grid or CSS Framework? What should I use for my next project?” It is a question often asked by web developers, specifically new ones after they are introduced to the CSS Grid layout. CSS Grid layouts allows developers to build custom complex layouts with absolute control only by using Native CSS properties without relying on any frameworks which are bound by basic 12 column grid layouts plagued with default styling rules and do not offer a lot of room for customization. On the other hand building grid layouts with frameworks like Bootstrap feels like a breeze without the need of writing any CSS style rules or media queries to make the layout responsive.
