10 Best Software Testing Certifications To Take In 2021

Software testing is fueling the IT sector forward by scaling up the test process and continuous product delivery. Currently, this profession is in huge demand, as it needs certified testers with expertise in automation testing. When it comes to outsourcing software testing jobs, whether it’s an IT company or an individual customer, they all look for accredited professionals. That’s why having an software testing certification has become the need of the hour for the folks interested in the test automation field. A well-known certificate issued by an authorized institute kind vouches that the certificate holder is skilled in a specific technology.

June ‘21 Updates: Live With Cypress Testing, LT Browser Made Free Forever, YouTrack Integration & More!

Howdy testers! June has ended, and it’s time to give you a refresher on everything that happened at LambdaTest over the last month. We are thrilled to share that we are live with Cypress testing and that our very own LT Browser is free for all LambdaTest users. That’s not all, folks! We have also added a whole new range of browsers, devices & features to make testing more effortless than ever.

Are Agile Self-Managing Teams Realistic with Layered Management?

Agile software development stems from a philosophy that being agile means creating and responding to change swiftly. Agile means having the ability to adapt and respond to change without dissolving into chaos. Being Agile involves teamwork built on diverse capabilities, skills, and talents. Team members include both the business and software development sides working together to produce working software that meets or exceeds customer expectations continuously.
