Stop Losing Money. Invest in Software Testing

I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.

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.

Test Optimization for Continuous Integration

“Test frequently and early.” If you’ve been following my testing agenda, you’re probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. I’ve encountered several teams who have a lot of automated tests but don’t use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.

In today’s fast-paced world, the primary goal of every business is to release their application or websites to the end users as early as possible. As a result, businesses constantly search for ways to test, measure, and improve their products. With the increase in competition, faster time to market (TTM) has become vital for any business to survive in today’s market. However, one of the possible challenges many business teams face is the release cycle time, which usually gets extended for several reasons.
