Check out the latest blogs from LambdaTest on this topic:
As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.
Hey everyone! We hope you had a great Hacktober. At LambdaTest, we thrive to bring you the best with each update. Our engineering and tech teams work at lightning speed to deliver you a seamless testing experience.
Companies are using DevOps to quickly respond to changing market dynamics and customer requirements.
Let’s put it short: Appium Desktop = Appium Server + Inspector. When Appium Server runs automation test scripts, Appium Inspector can identify the UI elements of every application under test. The core structure of an Appium Inspector is to ensure that you discover every visible app element when you develop your test scripts. Before you kickstart your journey with Appium Inspector, you need to understand the details of it.
There are times when developers get stuck with a problem that has to do with version changes. Trying to run the code or test without upgrading the package can result in unexpected errors.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
