Putting Together a Testing Team

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.

How To Use Appium Inspector For Mobile Apps

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.
